This article explores these technological advancements in-depth, highlighting how they are revolutionizing the future of tire disposal.

The General Process Of Tire Shredding Today

In simple terms, tire shredding is the process of breaking down tires into smaller pieces, often called tire chips or rubber mulch. This begins with the collection of used and discarded tires. These can be sourced from various locations, such as landfills, garbage dumps, and even old warehouses.

Once collected, the tires are placed on a tire cutting machine. Here, the tires are cut and ground down into smaller pieces. The shredding process may go through multiple stages, depending on the intended use of the tire chips. This ensures that the resulting material is of the appropriate size and consistency.

The shredded material is then sorted and processed further to remove foreign elements, including metal wires and fibers, commonly found in tire construction. The product—clean, shredded tires—can be used in various applications, from road construction to playground surfaces.

Traditional Equipment And Techniques Used

The machinery used in the tire shredding process is robust and designed to withstand the wear and tear of heavy-duty operations. Traditional equipment typically involves using tire shredders, grinders, and granulators. Each machine serves a different purpose, breaking the tires into smaller pieces.

Tire shredders are the first stage in the process. These machines have potent blades that cut the tires into smaller chunks. Grinders and granulators then come into play, breaking down the chunks into smaller pieces or granules. These machines are often custom-built and designed to handle the rigors of shredding rubber, a tough and resilient material.

In terms of techniques, most traditional tire shredding processes involve using a conveyor belt system to feed the tires into the shredders. The shredding happens at room temperature, a process known as ambient shredding. While effective, these traditional methods are now being complemented or replaced by more advanced techniques.

Implications For Waste Management

Tire shredding has significant implications for waste management and environmental sustainability. For starters, shredded tires take up significantly less space than whole tires. This means that more shredded tires can be accommodated in each space, reducing the strain on landfills.

Furthermore, tire chips derived from shredding are highly versatile. They can be repurposed in various industries, including civil engineering, construction, and even energy generation, where they are used as fuel. This repurposing extends the lifecycle of the tires, reducing the overall need for raw materials.

In a country that imports 90% of its food, discarded food accounts for about half of Qatar’s municipal garbage. These statistics point to the loss of millions of riyals each year, in the form of food wastage. The food in landfills rots to release greenhouse gases like methane which are responsible for the rise in temperatures which contributes to global warming.

According to Project Drawdown, the global leader in quantifying climate change strategies, reducing food waste is the single greatest solution to reverse climate change, which could draw 87 gigatons of CO2 out of the atmosphere, way ahead of a global plant-based diet, electric cars, regenerative agriculture or even utility-scale solar panels.

What is Wa’hab?

Wa’hab is fighting food waste in Qatar by implementing the 3 Rs of sustainable food waste management – Reduce by creating awareness on food waste impacts, Reuse surplus by redistribution and Recycle food waste to nutrient rich soil enhancer.

Wa’hab was the product of an inner calling, founded on a dream to utilize food to bring about greater public good. We have been able bring the community together under the umbrella of ‘Wahab Food Heroes’, a group with more than 150 volunteers from various backgrounds, religions and cultures.

wahab-qatar

Creating Mass Awareness

Schools and universities have a major role in educating children about the importance of reducing food waste. Children are our future: if we can influence them to make better choices to reduce, reuse and compost food waste, we can assure ourselves of a better planet.

Sharing Surplus Food with the Community

Redistribution of surplus food to people in need provides them with good food and helps save cost, which would otherwise be spent on buying more food. Optimal use of available food also saves Qatar’s need to import more food to meet growing demands. There is a growing interest to donate surplus food in Qatar, with more public events and food festivals reaching out to local food rescue groups than ever before.

food-waste-management-qatar

Over the last three years, Wa’hab has been able to divert more than 200 tonnes of food from being thrown away into landfills. With clearer guidance on surplus food distribution laws, more businesses would be willing to share their excess food with the community.

Composting on Unusable Food

Composting is nature’s way of recycling organic waste by converting them into valuable soil amendment. By composting unusable food like vegetable peels, coffee grinds and plate scrapings, we add essential nutrients back into the soil, thereby replenishing the soil. It is also known to help sandy soils retain water and nutrients which is key to grow the next generation of crops, and ties in directly with Qatar National Vision 2030, which aims to achieve self sufficiency in food production.

Wa’hab aims to make composting easy and accessible to all by providing an array of composting solutions: ranging from machines intended for large scale commercial institutions to small compost bins for urban homes.

Bottom Line

Sustainability is not just about the bigger changes in society,  it’s just as much about the small choices we make in our everyday lives- choosing to buy that misshaped carrot the next time you go grocery shopping goes a long way to reduce food waste and improve the livelihood of those who grow our food.

Textile Waste – The Next Big Challenge After Plastic Pollution

By | | , ,
Leave a comment

For decades, plastic pollution has dominated environmental discussions and policy agendas worldwide. Yet another environmental challenge is rapidly escalating and deserves equal attention: textile waste. The unprecedented expansion of the fashion industry, particularly the rise of fast fashion, has transformed the way clothes are designed, produced, consumed, and discarded. As a result, textile waste is growing at an alarming rate, creating serious environmental, economic, and social consequences that extend far beyond overflowing landfills.

The global fashion industry has experienced extraordinary growth over the past two decades. Clothing production has more than doubled since 2000, while consumers now purchase approximately 60% more garments than they did fifteen years ago but keep them for only about half as long before disposal [1]. This shift reflects the success of fast fashion, a business model based on rapidly changing collections, low production costs, and affordable prices that encourage frequent purchases rather than long-term use. While this model has increased consumer access to fashionable clothing, it has also promoted a culture of disposability.

a pile of textile waste

The environmental footprint of the textile sector is substantial. According to the United Nations Environment Programme (UNEP), the fashion industry is responsible for approximately 2–8% of global greenhouse gas emissions and consumes nearly 215 trillion liters of water every year throughout its value chain [2]. Cotton cultivation requires large quantities of irrigation water and agrochemicals, whereas synthetic fibers such as polyester depend heavily on fossil resources and energy-intensive manufacturing processes. Together, these impacts make textiles one of the world’s most resource-intensive consumer products.

One of the most striking consequences of current consumption patterns is the enormous volume of textile waste generated every year. UNEP estimates that approximately 92 million tonnes of textile waste are produced annually worldwide, equivalent to a truckload of clothing being landfilled or incinerated every second [2]. If current production and consumption trends continue, global textile demand is expected to increase by more than 60% by 2030, placing additional pressure on natural resources and waste management systems [3].

Beyond visible waste, synthetic textiles have become a major source of invisible plastic pollution. Polyester, acrylic, nylon, and other synthetic fibers release microscopic plastic particles during washing. These microfibers pass through domestic wastewater and, despite the high removal efficiency of many wastewater treatment plants, significant quantities eventually reach rivers, lakes, and oceans. The International Union for Conservation of Nature estimates that around 35% of primary microplastics entering the marine environment originate from laundering synthetic textiles [4]. Today, microfibers have been detected in marine organisms, freshwater ecosystems, agricultural soils, drinking water, human blood, and lung tissue, raising growing concerns regarding their long-term ecological and health implications [2,5].

Textile recycling presents challenges that are considerably more complex than recycling many other materials. Modern garments frequently consist of blends of cotton, polyester, elastane, viscose, and other fibers, combined with dyes, chemical finishes, coatings, buttons, zippers, and decorative accessories. These complex material combinations make automated sorting and fiber separation technically difficult and economically expensive. As a result, recycling rates remain extremely low.

According to the Ellen MacArthur Foundation, less than 1% of clothing collected after use is recycled into new clothing of equivalent quality [1]. Most recovered textiles are instead downcycled into lower-value products such as insulation materials, industrial wiping cloths, mattress filling, or construction materials. Although chemical recycling technologies capable of recovering high-quality fibers are advancing rapidly, they remain expensive and have not yet reached widespread commercial deployment [6].

a pile of old clothes

The textile waste problem extends well beyond producing countries. Millions of tonnes of used clothing are exported every year to developing nations under the label of second-hand reuse. While extending garment lifespans can reduce environmental impacts, recipient countries often lack adequate collection, recycling, and disposal infrastructure. Consequently, large quantities of low-quality textiles accumulate in informal dumpsites, rivers, and coastal environments. Images of discarded clothing covering parts of Chile’s Atacama Desert and overflowing waste sites around Ghana’s Kantamanto Market have become powerful symbols of the hidden environmental costs of fast fashion [7].

Moving away from the current linear model of “take, make, use, and dispose” requires embracing circular economy principles. Circular textile systems seek to keep materials in productive use for as long as possible through better product design, repair, reuse, refurbishment, remanufacturing, and high-quality fiber-to-fiber recycling. Designing garments using mono-materials instead of blended fibers, reducing hazardous chemical additives, and improving product durability can significantly increase recycling efficiency while extending product lifespans [8].

Governments are increasingly adopting policies to accelerate this transition. The European Union’s Strategy for Sustainable and Circular Textiles aims to ensure that textile products placed on the European market by 2030 are durable, repairable, recyclable, and largely manufactured from recycled fibers [8]. Furthermore, since 2025, separate collection of textile waste has become mandatory across European Union Member States, creating new opportunities for recycling industries and circular business models [9]. Extended Producer Responsibility (EPR) schemes are also gaining momentum by making manufacturers financially responsible for collecting and managing textile products at the end of their useful life.

Technology will play an essential role in improving textile circularity. Artificial intelligence can enhance automated sorting systems, while digital product passports, RFID technologies, and blockchain platforms can improve material traceability throughout the supply chain. These innovations will help recyclers identify fiber composition more accurately and recover valuable materials more efficiently [8].

Consumers also have an important role to play. Choosing higher-quality garments, repairing damaged clothing, purchasing second-hand products, participating in clothing rental platforms, donating usable garments, and properly separating textile waste all contribute to reducing environmental impacts. Research indicates that extending the active lifespan of clothing by just nine months can reduce its carbon, water, and waste footprints by approximately 20–30%, depending on the product category [10].

The textile waste crisis demonstrates that environmental sustainability extends well beyond reducing plastic bags and packaging. Clothing has become one of the fastest-growing waste streams worldwide, driven by unsustainable production and consumption patterns. Addressing this challenge will require coordinated action involving governments, manufacturers, retailers, researchers, waste management companies, and consumers. By combining eco-design, innovative recycling technologies, responsible business models, supportive public policies, and more conscious consumption habits, the textile industry can evolve from one of the world’s largest sources of waste into a cornerstone of the circular economy. As attention increasingly shifts beyond conventional plastic pollution, textile waste is emerging as one of the defining environmental challenges of the twenty-first century.

8 Eco-Friendly Ways to Wash Your Car

By | | , ,
2 Comments

How do you normally wash your car? Most of us will answer “the driveway” as the place where we normally wash our car. Washing our car in the free driveway might be one of the most harmful things we do to our environment. Like the other wastewater from our home, the car wash wastewater doesn’t go into the septic to get into treatment. The car wash wastewater from the driveway goes straight into the sewer or drains and gets mixed with the river or local pond without any wastewater treatment. This chemical car wash water pollutes the aquatic life and its ecosystem.

There are many ways to clean your car, one of the best way is to clean via car vacuum cleaners. All the oil, gasoline, paint residues, dust, soap chemical, and other pollutants from the car wash water completely destroys the aquatic ecosystem. It is a must that we avoid polluting the aquatic ecosystem by following other eco-friendly methods instead of the traditional one.

Let us explore some of the eco-friendly ways in which we can wash our car and other automobiles.

1. Commercial Car Wash

Commercial Car wash is an obvious answer to clean our car in an eco-friendly way. Car wash centers are required to treat the wastewater before letting it go into the drain or sewer. In this way, the aquatic ecosystem doesn’t get polluted as the waste is treated beforehand by the wash centers. They also use a computer-controlled motorized pressure pump to efficiently clean our cars. It minimizes the use of water in cleaning the car.

commercial-car-wash

Using a commercial car wash or drive-through car wash saves you a lot of time and energy in cleaning your car even if it costs you some money. They also give you a thorough cleaning of your car, so your money spent will also be worth in the long run. Commercial car wash centers are probably one of the best ways to clean our car in an eco-friendly way.

2. Biodegradable soap

If you like to wash your car by yourself in your home, you can still do it in an eco-friendly way by using biodegradable soap. These soaps are better than your normal car wash liquid as it is phosphate-free and has no harmful chemicals. They are also water-based cleaners, so you can safely use it on your car to clean without affecting your environment.

The main reason why cleaning your car in the driveway causes harm is because of the chemical soap or liquid that you use. It contains harmful chemical with phosphate, sodium, and potassium that affects the soil and water when mixed. When you use a biodegradable soap instead of your normal one, you can still wash your car in your home without affecting the environment.

3. Waterless car washing

There are other ways in which you can wash your car without the use of water. One such way is to use car wash spray. Using a spray gun, you can wash your car while also minimizing the use of water. You can do spot cleaning with a spray gun and wipe the dust off with a washcloth. It is effective in spot cleaning than using a pipe or hose.

environmentally-friendly-car-wash

The main advantage of this method is that no chemical water is let into the drain and sewers, so you are cleaning your car in an eco-friendly way. While you won’t get the satisfaction of cleaning your car whole using a pipe, this way of using the spray gun to clean the car is definitely better for the environment.

4. Don’t let chemical water mix into the sewer

If you are used to cleaning your car in your home using a chemical or bio-friendly soap, you can still be eco-friendly by following this advice. The environment gets affected when the wastewater gets mixed into the soil or the sewer, so you can prevent this to be eco-friendly in cleaning your car.

You can use a bucket to collect all the dirty chemical water from the cleaning before it reaches into the sewer. Then, you can dump this waste chemical-laced water into your kitchen sink or toilet. This will work because the water from your house gets treated before it reaches the river. It is a great eco-friendly way to wash your car.

5. Washing your car on gravel or grass

Washing your car above gravel or grass might not be completely eco-friendly, but it’s still better than doing nothing. The stone and sand mixture in the gravel or the grass will filter the wastewater from your car wash, so it will not reach the nearby sewer to get mixed into the river.

environmentally-friendly-car-washing

The wastewater will soak into the ground and settles there. It will still affect the soil and the land, but the aquatic ecosystem will be protected as the wastewater will not mix into the sewer.

6. Use the chemical subtly

Even if you use a biodegradable or other chemical soap to clean your car, you should use it as little as you need to clean. Using the chemical soap abundantly without any caution will clearly affect the environment much.

So it will be prudent for you to use the chemicals as little as possible so the environment doesn’t get affected much. The biodegradable soap that was mentioned earlier will also contain a few harmful chemicals, so you must use those carefully as not to affect the environment.

7. Cleaning Windows using Vinegar

Instead of using chemical soap to clean your windows, you can use vinegar. Use a spray bottle filled with vinegar and washcloth to do a spot cleaning of your windows. It will clean your car while not affecting the environment in any way.

8. Using reusable washcloth

Instead of using a one-time use cloth or wipes to clean your car, you can use a reusable washcloth. Using the reusable washcloth will benefit the environment in a great way. It reduces the accumulation of dust while also saving your money on buying new clothes.

Conclusion

Many of us are not aware of the environmental problems caused by cleaning the car in our home. It can be easily mitigated by following any of the steps listed above but using a commercial car wash center is considered the best option for both the car and the environment. We hope you got some information on how to clean your car in an eco-friendly manner.

Leave a comment

Credit cards are a powerful financial tool with several advantages when it comes to managing money. There may, however, be a temptation to overspend. And besides damaging your financial health, the resulting spiralling debt can severely limit your ability to make eco-friendly choices. This is why responsible credit card use and debt management are crucial.

How to use your credit card responsibly

Table of Contents

Credit Cards and the Debt Trap Risk

Credit cards allow you to spread the cost of big purchases and offer perks such as cashback rewards and fraud protection. The introduction of eco-friendly credit cards gives consumers a more ethical way to buy goods while the card provider makes donations to green causes.

But whatever type of credit card you have, there’s a risk of falling into a debt trap if you overuse it.

If you can’t pay back what you borrow, the debt can spiral out of control, and with high interest rates and default penalties you could end up owing a lot more than you borrowed.

If you’re concerned about environmental issues such as pollution, climate change, and deforestation and you find yourself with too much credit card debt, it becomes harder or impossible to make key eco-friendly choices.

As you struggle to pay off the debt it’s unlikely you’ll have enough money to invest in green energy solutions such as solar panels or heat pumps, for example, which reduce energy bills as well as reduce your carbon footprint.

Credit Card Debt and Low Credit Scores

Besides limiting eco-friendly choices, credit card debt is also likely to lower your credit score. This happens because your card provider reports your outstanding balances and payment activity to credit reference agencies.

In fact, how much debt you owe on your credit card is a major factor that affects your credit score. If you max out your credit card by using the entire credit limit, you could see your credit score drop significantly. With a low credit score, you may have to pay higher interest rates on any other credit cards or loans you take out. On the other hand, responsible use of your credit card can improve your credit score.

How to Use Your Credit Card Responsibly and Build Your Credit Score

Responsible credit card use is one of the most effective ways to build your credit history and improve your credit score. Increasing your creditworthiness in this way opens up a range of affordable borrowing options in the future. Strategic use of a credit card includes keeping your balance low and making payments on time.

Here are the key steps in responsible credit card use.

Understand Your Credit Card Terms and Conditions

Credit card terms and conditions are often full of jargon that can be difficult to understand.

You need to know what the following mean.

  • Annual fee. Some credit card providers charge an annual fee. This is usually charged to your card every year on the anniversary of your account opening.
  • Annual percentage rate (APR). This is the yearly rate of interest you pay on your card’s outstanding balance. You can determine your card’s monthly interest rate by dividing the APR by 12.
  • Introductory APR. Many credit card issuers offer an introductory zero percent APR. While this lasts, you won’t have to pay interest charges on purchases or balance transfers.
  • Balance transfer fee. This is the amount a new credit card provider charges when you transfer your debt from another account.
  • Credit limit. Your credit limit is the maximum amount you can spend with your credit card.
  • Late payment fees. Card issuers can impose fees if you don’t make payments on time.

Pay Your Credit Card Bill Promptly

Making late payments on your credit card bill can result in fees or penalty APRs and damage your credit score. Make sure you pay at least the minimum by the due date each month. Ideally, pay off the entire balance each month, which will avoid interest charges. Consider setting up automatic payments so you never miss a payment.

Have a Credit Card Budget

It’s easy to overspend and indulge in impulse purchases when you have a credit card. You can avoid this temptation by having a budget in place to ensure you’re spending only what you can afford. This will keep your card balances low enough to pay off each month.

Set Up Account Alerts

Having email or text alerts on your credit card account helps you track your spending, avoid late payments, and identify fraud. Alert options may include:

  • Payment due date reminders.
  • Approaching credit limit notification.
  • Updates on your credit card balance.

How to Manage Credit Card Debt

There are various strategies you can use to pay off credit card debt, especially if you have multiple accounts. These approaches include the debt snowball process and the debt avalanche method. You could also get a balance transfer credit card or a debt consolidation loan.

Debt Snowball Process

The debt snowball approach is an accelerated payoff strategy that’s ideal if you have more than one credit card and struggle to stay motivated.

It entails making the minimum payment on all your credit cards and putting more money towards your debt each month, starting with the card that has the lowest balance. Once you’ve paid off that card, add that amount to the minimum payment on the card with the next-lowest balance.

Debt Avalanche Method

With the debt avalanche method, you focus first on balances with the highest interest rates. If the card with the highest APR also has a high balance, it can take a long time to pay off the first credit card. But it can also save you money by eliminating the most expensive debts first.

Balance Transfer Credit Card

Balance transfer credit cards offer an introductory zero annual percentage rate for a set period of time, during which you can pay off your debt interest free. If you have multiple balances, consolidating them with a balance transfer can also simplify monthly payments.

Debt Consolidation Loan

You can use a debt consolidation loan to pay off your credit card debt. Debt consolidation rolls several debts into a single monthly repayment, often with a lower rate of interest. This can reduce the total debt and you may be able to pay it off faster.

Summary

Responsible credit card use avoids getting into debt traps and compromising your financial health. And managing credit card debt effectively minimises interest charges.

Both of these strategies can help improve your credit status. They can also give you more spending power to invest in your future, including environmentally friendly choices.

The building roof is very important because it has a direct impact on thermal comfort and energy conservation in and around buildings. Urban green roofs can help to address the lack of green spaces in many urban areas.

Urban green roofs provides the city with open spaces that helps reduce urban heat island effect and provides the human population on the site with a connection to the outdoors. However, we must differentiate between two types of urban green roofs and assess their adaptability to Arab cities. This article provides an insight on green roofs and roof farming in Arab cities.

What are Green Roofs?

Green roofs are essentially sustainable and passive design features of vegetation surfaces applied to a waterproofing layer of a suitable conventional roof build-up in rainy climates. In rainy countries such as Austria, Germany and Belgium green roofs are recognized as a significant source-control feature, contributing mainly to stormwater management and drainage control.

Green roofs not only store water at roof level, but also reduce the run-off rate from the roof, which in turn reduces the underground drainage network requirements. It is also possible to use or harvest rainfall from a green roof, although the amount of rainwater that can be used may be reduced depending on the type of green roof implemented.

Generally speaking, there are no green roofs in hot arid climates. In in the Middle East, it is hardly to find any examples of successful green roofs. According to European norms the minimum annual precipitation rate for a green roof should be more than 450-650mm. Therefore, it is impossible to grow a green roof in Cairo (26mm), Amman (276mm), Riyadh (20mm) or Dubai (10mm). Even coastal cities like Alexandria (190mm), Tunis (450mm) or Casablanca (425mm) witness extreme summers and drought periods that almost eliminates the sedum plants from recovery during the winter season.

Facing these facts, there are many voices in the Middle East that surprisingly continue pushing the idea of green roofs claiming to sustain it through artificial irrigation. An idea that make us lose the whole point of sustainability in an already water scarce region.

Unfortunately, across the Middle East there are large numbers of students, architects, clients and even researchers who have a wrong perception and a defective understanding of semantic of green roofs, which are essentially associated with the presence of renewable rain water. This is due to the unfamiliarity with word Green Roof in our region and the huge influence of the Northern imaged media.

Moreover, there are many researchers who talk about the positive side effect of green roofs that significantly save energy, enhance the thermal performance and comfort of buildings, particularly in terms of summer cooling, based on readings and studies made in countries with latitude higher than 40o with temperate or cold climates. What is missing here is local evidence based experimentation and practices that address green roof in the warm and hot climate not from a theoretical copy-paste approach.

The Real Problem

Arab cities suffer from serious problems that are similar to most other large cities in the developing countries. Among the most visible manifestations of the challenges posed by rapid urbanization are many environmental problems, such as pollution, dense urbanization, urban heat island effect and inversed greenhouse effect during winters. In fact, the dense concentration of automobiles and polluting buildings created a negative impact on the environment. In fact, the rapid urbanization not only created environmental problems but also economic problems.

For example, air conditioners are running, over the whole summer period, trying to deliver an endless demand for cooling. This leads to increasing prices of electricity bills. This is due to the lack of energy codes, which means that roofs are without or with very poor insulation. Additionally, cities suffer from constant desert sand depositing together with disappearance of green spaces which lead to deprivation of open space.

During the last decade many Arab cities witnessed several times inefficient food production and distribution, inaccessibly high food prices and above all locally grown food, loaded with toxic contaminants. The fast-growing population and the failing government approaches to housing and spatial planning policies contributed to the growth off informal settlements within and around the center.

For example, 8 million Egyptian live in informal settlements in Cairo with problems of unemployment, pollution, transportation, inadequate drainage and sewerage, and lack of usable urban open spaces. In Cairo, the amount of green space per inhabitant is roughly equivalent to 0.33 square meters per person (3.5 square feet), one of the lowest proportions in the world. Among the above listed problems stands out a common denominator. It is the building roof.

Roof Farming as an Alternative

Under the influence of the all those issues emerges the idea of roof farming. Urban roof farming has long been promoted as an easy and effective strategy for beautifying the built environment and increasing investment opportunity. Roof farming can help to address the lack of green space in many urban areas. Urban roof farms provides the city with open spaces that helps reduce urban heat island effect and provides the human population on the site with a connection to the outdoors. Challenged by environmental and pollution, Cities suffer from locally grown food, loaded with toxic contaminants that threat the health.

In the last couple of years, Cairo suffered from an inefficient production and food distribution and inaccessibly high food prices. The population explosion and the tendency to build on agricultural land have acted to limit the resources of city families and their access to healthy edible products. With a little effort and money, roof farming can contribute in improving the families quality of life and provide them with healthy food and raise their income, this is besides the environmental and aesthetical role it plays.

For example, Cairo citizens and some governmental authorities acknowledged the problem of food contamination & distribution and are mapping measures and methods that can guarantee safe food.While it is not new, the notion of planting rooftops in Egypt has only recently been implemented. In the early 1990s at Ain Shams University, a group of agriculture professors developed an initiative of growing organic vegetables to suit densely populated cities of Egypt. The initiative was applied on a small scale; until it was officially adopted in 2001, by the Food and Agriculture Organization (FAO).

There are several case studies that represent successful projects implemented by different non-governmental organizations (NGO), public institutions and private civil initiatives. For example Ibn Kassir foundation, in Al-Zawya Al-Hamra, Cairo, created a roof farm from wooden containers (barrels) with plastic sheets filled with peat moss or perlite used as substrates. The drainage is driven through small plastic hoses to buckets. This system is producing leafy crops such as parsley, radish, and carrots. A square meter using this method would cost around 400 Egyptian pounds (LE).

Finally, in many Arab cities, where many environmental social and economic problems exist, a beam of light emerges to contribute in solving many of these interrelated problems. Planting our roof with different kinds of vegetables and fruits or even any kind of green plants will change lots of things. It is certain that roof gardening and farming have measurable qualitative and quantitative benefits. The techniques for implementation are simple and doable and above all cost efficient. However, no roof gardens can be created without the knowledge of the factors affecting the creation and design. The most important factors are the climate, the constructional and economic factors.

Regarding green roofs, we shall only address this issue based on experimental and monitored cases. More importantly, a vision is required to be drawn together with long term strategy, adopting the holistic approach of roof farming and providing support and sustainability. It is this holistic approach that can solve many problems of different background and aspects, and can contribute to improving the quality of life of the dense Arab cities.

By exploitation of such roofs, their development and planting; a reasonable ratio of green areas can be reached in the near future. A ratio of 4 square meters per person can be provided once the suitable green framing roofs have been developed and exploited.

We compare the number of road fatalities per 100,000 population between the USA and other English Speaking Countries – the UK, NZ, Canada, Australia and Ireland

International Road Safety Report

  • USA road fatalities are 11.78 people per 100,000 population – highest of English-speaking countries
  • New Zealand is second highest, with a rate of 6.01 deaths per 100,000 people
  • Canada is third behind the USA and NZ with 4.59 road fatalities per 100,000 population
  • Australia is fourth highest in terms of road fatalities with a rate of 4.26
  • Ireland’s road fatality rate per 100,000 is 2.96
  • UK has lowest fatalities per 100,000 population, of 2.26 among English-speaking OECD countries

Road fatalities in English-speaking OECD countries

One of the most troubling aspects of modern industrialized society in the USA is the trade-off between ease of transportation and its dangers. Unfortunately, people lose their lives to road and traffic accidents all over the world, and the United States is no exception. Efforts have been made to reduce the road toll (or road deaths/road fatalities) through more stringent safety standards, tougher penalties for ignoring safety laws (e.g., making seat belt use mandatory, harsher punishments for driving under the influence of alcohol), and education campaigns by federal, state, and local road safety authorities.

Road safety is a significant challenge for nations in the Organization of Economic Cooperation and Development (OECD). As highly industrialized, wealthier nations, these countries have higher rates of car or vehicle ownership than non-OECD countries.

Among the anglophone (English-speaking) countries, there are many disparities in terms of road fatality statistics. The United States, one of the most developed countries, unfortunately ranks highest among English-speaking countries when it comes to road fatalities, while the United Kingdom consistently maintains the lowest rates. Australia falls somewhere in the middle, while New Zealand, by way of comparison, has a far less safe record.

Here, we’ll delve into the statistics about road fatalities and compare them among leading English-speaking nations.

road safety in English-speaking OECD countries

United States road fatality statistics – the benchmark

Road fatalities are a significant concern in the United States, as it consistently ranks among the most dangerous. According to the US Department of Transportation’s National Highway Traffic Safety Authority, 38,824 road fatalities were recorded during 2020, the highest year on record since 2007.

US fatality rates per capita and registered vehicle

The fatality rate per 100,000 population is an important indicator of road safety. In 2020, the United States had a fatality rate of 11.78 deaths per 100,000 population. Comparatively, New Zealand had the second highest fatality rate among the countries analyzed, with 6.01 deaths/100,000 population, while the UK had the lowest rate at 2.26 deaths per 100,000 population, while the OECD median fatality rate was 4.09.

Examining the changes in fatality rates over time can reveal trends in road safety. From 1990 to 2020, the fatality rate in the United States decreased from 17.9 to 11.78 deaths per 100,000 population. This downward trend indicates improvements in road safety measures. However, it is important to note that there was a slight increase in the fatality rate from 2017 to 2020. The lowest point was in 2014, when the rate dropped to 10.3, after which the fatality rate trended upward to 2020.

road safety report usa

In 2020, the United States had a fatality rate of 1.30 deaths per 10,000 registered vehicles. Compared to other countries, the United States had a relatively higher fatality rate in this category. The closest English-speaking country was New Zealand, at 0.69 deaths per 10,000 registered vehicles. The OECD median is 0.52.

Breakdown by Age Group, Road User Group, and Gender

In 2020, the United States had a proportion of road deaths by age group as follows: 3% in the 0-14 age group, 17% in the 15-24 age group, 63% in the 25-64 age group, and 17% in the 65+ age group. Compared to other English-speaking OECD countries, the United States (17%) had a similar proportion of road deaths in the 15-24 age group to Canada (17%) and Australia (17%), but higher than Ireland (10%) and the United Kingdom (16%). Older drivers 65 and older involved in fatal crashes made up 17% of the total; similar to the 15-24 age bracket.

road deaths in USA

Looking at the road user group statistics, the United States had 35% of road deaths categorized as passenger car occupants, 17% as pedestrians, 14% as motorcyclists, 2% as cyclists, and 31% as other. Comparing these figures to other OECD English-speaking countries, the United States had a significantly lower proportion of road deaths among cyclists compared to Ireland (7%), Australia (4%), and the United Kingdom (10%), but a higher proportion of road deaths in the “other” category.

road safety usa

Key findings from the NHTSA showed that Urban fatalities increased by 8.5%, and rural fatalities increased by 2.3%. 42 out of the 50 states including the District of Columbia saw increases in the number of road deaths. Nighttime (6 p.m. to 5:59 a.m.) fatalities increased by 12%; daytime (6 a.m. to 5:59 p.m.) traffic fatalities increased by 1.4%.

When considering gender, the United States had 72% of road deaths among males and 28% among females. This distribution was similar to Canada and Australia but different from the United Kingdom, where males accounted for 77% of road deaths.

The United States exhibited certain similarities and differences in road fatality statistics compared to other OECD English-speaking countries, highlighting the importance of analyzing these figures to identify areas for targeted road safety measures.

New Zealand road fatality statistics

With 6.01 deaths recorded for every 100,000 people in the population, New Zealand is one of the least safe nations when it comes to the risk of being killed on the road. This puts them in the seventh worst position among the OECD countries with the highest rate of fatalities. Their incidence of fatalities was 0.69 for every 10,000 automobiles registered in their state. New Zealand’s trend line for fatalities per 100K population has been downward, halving each decade: 21.4 in 1990, 12 in 2000, and 8.6 in 2010.

In terms of the types of people who were killed while using the road, around 66% were either passengers or drivers, 10% were pedestrians, 18% were motorcyclists, and 4% were cyclists. The mortality rate in New Zealand was 0.66 cases for every 100 million vehicle kilometers traveled (VKT).

United Kingdom road fatality statistics

The UK is the fourth safest OECD country in terms of road fatalities per 100,000 population with a rate of 2.26, just behind the top three of Iceland, Sweden, and Norway. As mentioned above, the UK ranks first when compared to other English-speaking countries. Their fatality rate per 10,000 registered vehicles was slightly higher at 0.38, behind Japan and Spain (0.37) and Switzerland (0.35). However, they have managed to halve this number over the past two decades – their fatality rate was 1.2 in 2000 and 0.5 in 2010.

43% of road fatalities were suffered by passenger or car occupants, 23% by pedestrians, 20% by motorcyclists, 10% by cyclists, and 5% by “other.” 77% were male and 23% were female. 2% were aged 0-14, 16% 15-24, 58% 25-64, and 24% over the age of 65.

The fatality rate in the United Kingdom per 100 million VKT was 0.34.

Ireland road fatality statistics

Ireland is towards the top of the league tables in terms of road fatality safety for English-speaking OECD countries. Their fatality rate per 100,000 population is 2.96. Ireland’s fatality rate has trended downward since 2000, where their road fatality rate per 100,000 was 11, more than halving in a decade at 4.7 in 2010. It would seem they achieved another halving of the fatality rate in the ensuing decade. In another measure, Ireland’s fatality rate per 10,000 registered vehicles is 0.52.

The fatality rate per 100 million VKT was 0.41, the OECD median.

In terms of age-group, in 2020 Ireland had 5% of deaths in the 0-14 age group, 10% in 15-24, 63% in 25-64 and 22% in 65+.

Canada road fatality statistics

Canada is towards the middle of the pack when it comes to road safety, with a rate of 4.59 road fatalities per 100,000 population. Canada’s road fatality statistics have trended downward in the previous decades, recording a rate of 9.5 in 2000 and 6.6 in 2010. Their fatality rate per 10,000 registered vehicles was 0.68.

58% of Canadian road fatalities were among car drivers or passengers, followed by 16% of pedestrians, 14% of motorcyclists, and 3% of cyclists. Canada’s fatality rate per 100 million vehicle kilometers traveled (VKT) was 0.47. 3% of deaths were recorded among 0-14s, 17% among 15-24s, 59% among 25-64s, and 22% over the age of 65.

A quick look at Australia

In terms of Australia’s road fatality rate per 100,000 population, Australia’s rate was 4.26, ranking 20th out of the 36 OECD nations. This declined from a rate of 6.1 in 2010, trending downward over the next decade. Australia sits ahead of several other English-speaking countries, which are Canada, New Zealand and the United States.

The fatality rate per 10,000 registered vehicles was 0.55, ranking 18th among 30 nations with available data. This dropped consistently over the preceding ten-year period, from 0.8.

As for the fatality rate per 100 million vehicle kilometers travelled (VKT) in 2020, Australia’s rate was 0.44 –9th out of 15 nations with available data. In Australia during 2020, vulnerable road users (motorcyclists, pedestrian, or cyclists) accounted for 35% of total road deaths, which is lower than the OECD average of 44%.

Australia’s distribution of deaths by age group shows 4% between 0-14s, 19% between 15-24s, 59% between 25-64s, and 19% for over 65s. The gender breakdown was 73% male and 27% female. In terms of deaths by road user group in Australia, 48% were passenger car occupant, 12% were pedestrians, 17% motorcyclists, 4% cyclists and 19% were classified as “other”.

Can we get to Zero road toll?

It would seem that many English-speaking OECD countries have their own challenges to bringing their road tolls or road fatality statistics down. Most trends in the OECD, more broadly, have shown a decrease in road fatalities in the last decade or two. Even in the least safe countries such as the United States and New Zealand, great strides have been taken to reduce the road fatality rate. New Zealand’s rate per 100,000 has roughly halved each decade.

Though cars may be safer and education campaigns may be more prevalent, it may take a quantum leap in technology – accessible for all countries – to whittle the road toll down to even lower levels, or that long-strived for zero number.

Urban Integration of Waste-to-Energy Facilities: A Comparative Case Study and Framework for Sustainable Neighborhoods

Leave a comment

The paper addresses the global and local shift towards the circular economy as a tool to achieve environmental sustainability and reduce climate impacts, given the global challenges of converting waste into energy. Through an analysis of global studies, the trend towards the circular economy and successful global standards, specifically the Danish model (Copenhill WTE plant) and Singapore (Tuas One WTE Plant), and how we utilize waste and achieve sustainability, this study discusses global strategies in the local context in Jordan, where it identifies current infrastructure challenges and proposes a sustainable local framework aimed at improving waste management and supporting the goals and strategy for sustainability in Jordan for 2030.

The world is moving toward sustainability, which involves bringing about a radical change to transform what is traditionally viewed as an environmental burden into a sustainable resource that delivers benefits in many areas.

Sustainable development, according to the United Nations, is development that meets the needs of the present without compromising the ability of future generations to meet their own needs [1]. Sustainable development has multiple facets and benefits in several areas, including human health, the environment, social justice and equality, livelihoods, security, and well-being for all, as recognized by AASHE[2]. The circular economy system prevents materials from becoming waste; instead, it revitalizes nature. This system focuses on waste elimination, material recycling, and the restoration of natural resources to protect the environment. This approach addresses climate change and other challenges. The system is based on three principles: first, waste and pollution reduction; second, the circulation of products and materials; and third, the restoration of natural systems. This system relies on the principle of “closing the loop.”

Among the organizations aiming to accelerate the global transition to a circular economy is the Ellen Foundation, which focuses on waste reduction through reuse to achieve a fundamental approach to a sustainable system [3]. The organization indicates that cities contribute 80% of global GDP, making them the largest consumers of resources and the primary driver of the transition to a circular economy. This is because they consume 75% of natural resources, generate 50% of global waste, and are responsible for 60% to 80% of greenhouse gas emissions. Artificial intelligence (AI) solutions are used to identify patterns, predict processes, improve operations, and provide recommendations using diverse data sources [4].

To scientifically implement the principles of the circular economy, the twelfth Sustainable Development Goal (SDG 12) of the United Nations stands out. It stipulates a substantial reduction in waste production by 2030 through prevention, reduction, recycling, and reuse, emphasizing the environmentally sound management of chemicals and waste throughout their lifecycle [5]. Denmark is a world leader in the circular economy model. While many countries have successfully harnessed waste for their benefit, Denmark has transformed waste management facilities into sustainable projects. Although Denmark boasts numerous sustainable factories, the Copenhill waste-to-energy plant stands out for embodying the concept of social and urban sustainability. It integrates an industrial facility with a 400-meter-long artificial ski slope on its roof, serving as a public space for the area and its residents. Its smokestacks are designed to emit emissions in the form of visual vapor rings, symbolizing visual awareness. This has made Copenhagen the first carbon-neutral city [6].

Despite the magnitude of the challenges in Denmark, where the average individual generates about 755 kg of waste per year, compared to the European Union where the average individual generates about 517 kg per year, Denmark has made a historic leap. While the percentage of landfill waste was about 44% before the 1990s, it has now decreased to levels close to zero, about 0.7%. In contrast, municipal waste is converted into energy for cities at a rate of 55% through the burning of non-recyclable waste, and recycling rates have reached between 45%-50%, with goals to raise these rates to 60% by 2030 [7].

Jordan produces approximately 2.7 – 3 million tons of waste annually. The problem in Jordan is that the landfill rate reaches over 85-90%, with most of it going to the (Ghabawi and Akeeder) landfills. The recycling rate is minimal, between 7-10%. Organic waste, particularly food scraps, constitutes over 50-60% of the total waste volume[9]. A very high percentage that generates methane gas. In line with the goals and vision of the Jordanian state to modernize the economy towards a circular economy, reduce the landfill rate, and strive to achieve its 2030 targets of diverting 60% of solid waste from landfills and reducing the landfill rate from approximately 85% to less than 40% by 2030, efforts are underway to increase recycling rates and material recovery to 30%, and to process 30% of organic waste into compost and biogas for energy production[8].

Case Study 1: Denmark (The CopenHill WTE Plant)

The Copenhill ski resort, designed by the architectural firm Bjarke Ingels Group (BIG), was completed in October 2019 in Copenhagen, Denmark. It is a truly unconventional facility.

The feasibility of building a ski slope at the top of an existing facility was uncertain, as Denmark lacks natural mountains and snowfall is scarce. Skiing on an artificial surface is a novel concept. However, some studies analyzed the number of visitors to ski slopes and the number of active skiers in the area. Based on this data, they estimated that between 42,000 and 57,000 visitors use the site annually. The biggest challenge of the project was helping all stakeholders understand that it was not merely an engineering, sporting, or architectural project, but rather a multi-faceted endeavor requiring a holistic approach to design and implementation.

The ingenious concept behind the resort is to transform a state-of-the-art waste-to-energy plant into a clean energy facility serving 150,000 homes. This station converts 440,000 tons of waste annually into electricity and heating. At the top of the station is a recreational park featuring a 450-meter ski slope, a walking trail, and an 85-meter-high artificial climbing wall. The design goes beyond simply providing enjoyment for local residents; it aims to propel the Danish capital towards sustainability. Costing $670 million USD, this is a crucial step towards making Copenhagen the first carbon-neutral capital, a goal it is expected to achieve by 2025.

Among the key technologies used at the station are waste-to-energy conversion, emission reduction systems, selective catalytic reduction (SCR), and carbon capture technology.

The station also features sustainable architecture and integrated recreational facilities, including a ski slope, climbing wall, and green spaces[9].

copenhill waste to energy plant

Detailed Timeline and Construction Phases of the Project between (2009 – 2019).

In 2009, the Ministry of Environment won the engineering contract. In 2011, Bjarke Inglesa Group (BIG) won the competition to replace the old station. In March 2014, contracts for the structural pouring and concrete work were awarded, marking the start of the foundation phase. In March 2017, the power station was officially completed, and the machinery and thermal processing units began operation. In the fall of 2019, the roof and recreational facilities, including the world’s tallest climbing wall and ski slope, were officially opened to the public.

The aesthetic engineering and roof preparation phase (2017-2019) included the construction of a 400m long ski slope at an altitude of 900m, the building of hiking trails, an 85m high external climbing wall, and the integration of an emissions station designed to produce the distinctive smoke rings[10].

The building’s concept and design are divided into interactive green energy elements. The idea breaks the traditional image of factories, and considering the natural topography of Copenhagen, the designers created a mountain that offers various sports, including skiing and mountaineering, in the heart of the city. The building also houses administrative offices and an environmental education center to raise awareness among visitors about the importance of recycling and clean energy production.

The building’s architectural masses form a sloping shape, precisely tailored to the requirements of the industrial machinery and waste incineration equipment inside. The masses slope down from the top of the building, creating a contemporary industrial style. The facades of the station are composed of massive, overlapping, and stacked aluminum pieces, like bricks, which reinforces the building’s industrial identity. Double-glazed windows in the facades incorporate long strips of glass that allow natural air to penetrate deep into the factory, and the office spaces are illuminated at night to reflect the rhythm of work within the station[11].

The plant is equipped with two furnace lines and a combined turbine and generator system. Each line burns 35 tons of waste per hour. It is designed to process approximately 400,000 tons of waste annually, generated by 600,000 people and at least 46,000 companies. Electricity is supplied to at least 50,000 households and central heating to 120,000 households. Steam at 440°C and 70 bar pressure is provided, doubling electrical efficiency. The innovative DynaGrate combustion grid technology is characterized by its flexibility in using waste fuels, optimal combustion, and low maintenance costs. The entire cooling system is fully integrated and protected within a steel column, with the grid components not touching, thus reducing friction. The mechanical agglomeration of the waste layer on the grid ensures thorough mixing and combustion conditions. The water cooling system provides the high calorific value necessary for the flexibility in using different fuel types. The organic carbon content is approximately 0.2% in the bottom ash[12].

Plant design data (Per line)

The Dyna-Grate water-cooled system does not cool the air but provides complete control over the primary combustion air. This improves the combustion process to reduce nitrogen oxides. B&W Volund options operate at oxygen levels between 4.5% and 5% and nitrogen oxide levels between 200 and 250 mg/m³ before the combustion gases reach the SCR filter. Furthermore, reducing excess air leads to lower nitrogen oxide emissions. The VoluMix excess air system is designed using computational dynamics (CFD), which reduces carbon monoxide and total organic carbon emissions. VoluMix also injects secondary air into the combustion zone, resulting in complete combustion in the gaseous phase[12].

The original concept behind BIG’s CopenHill chimney mechanism involved creating a steam ring generator. The mechanism works by capturing rising steam, while an internal unit condenses and traps the steam in a circular chamber. This steam is then released as a giant smoke ring made of pure steam each time 25 kg of CO2 is burned, serving as a tangible visual representation of emissions. Despite the success of the prototypes, the steam ring-blowing mechanism was not permanently implemented in the final building.

Currently, the plant operates as one of the cleanest waste-to-energy plants in a world where 440,000 tons of waste are converted annually into electricity and heating. Instead of a continuous upward movement, the chimney releases a massive steam ring into the sky. The purpose of these rings is to provide a tangible visual representation, with a smoke ring being released into the air for every ton of CO2 emitted, alerting local residents and the world to the scale of emissions[13].

The factory’s architectural envelope is made of 3.3-meter-wide extruded aluminum blocks. Aluminum was chosen for its ease of recycling, longer lifespan, and corrosion resistance. It is laid in an interlocking, brick-like pattern, improves water quality, does not require external coatings, and is easy to disassemble and recycle at the end of its lifecycle. Light enters the factory to its deepest point through integrated glass strips, providing natural lighting for the administrative spaces. The structure is built of steel and concrete and is designed to support an integrated public program that superimposes its basic service infrastructure[14].

Case Study 2: The Tuas One WTE Plant (Singapore)

The Tuas One waste-to-energy plant is located in the Tuas Industrial Estate in southwestern Singapore. Spanning approximately 4.8 hectares, this sixth waste-to-energy plant in Singapore can incinerate 3,600 tons of waste daily, generating 120 megawatts of electricity. The electricity produced powers approximately 240,000 residential units belonging to the Housing and Development Board. The Tuas One plant was developed as a public-private partnership to provide waste incineration services.

Initial operations commenced on July 27, 2022, at the National Environmental Company, while a second phase, developed under a design, build, own, and operate model, began in December 2021. Since then, operational capacity has increased. The plant will provide waste services for at least 25 years, helping Singapore meet its long-term waste management and energy needs. The incineration process generates energy to meet the demand for waste-to-energy conversion, with 90% of the waste being reduced to ash [15].

Tuas One Waste to Energy Plant

Integrated Waste Management Facilities

In 2019, the total solid waste amounted to 7.23 million tons, with 59% of this waste being recycled. Waste-to-energy plants in Singapore incinerated approximately 2.98 million tons in the same year. With the increasing population, waste is expected to rise. Unlike existing waste-to-energy plants, the organization adopts a different approach to comprehensive waste management, processing multiple types of waste to maximize resource and energy recovery and minimize environmental impact and land consumption. Waste consists of incinerable and recyclable waste collected by the National Recycling Programme[15].

Timeline of Tuas Water Rehabilitation Project

On July 3, 2019, the project was awarded to a joint venture between Brothers Engineering and Civil Contracting Company and China Harbour Engineering Singapore Limited. This followed the construction of internal pumping stations to the plant. These stations consist of five shafts extending 80 meters underground. units within the Tuas wastewater treatment plant.

The second phase of the technical decision support system extends under the Air Rajah Road and terminates at the Tuas Water Treatment Plant. This phase includes a 40-kilometer southern tunnel connecting to the existing deep tunnels and creating an interconnected network that transports wastewater from the existing sewage system to a depth of 60 kilometers. Upon completion of the second phase in 2025, the existing conventional water treatment plants in Jurong and Ulu Bandan will be decommissioned. 37 intermediate pumping stations will thus free up approximately 83 hectares of land for alternative uses[15].

The building, completed in 2019, operates at a massive capacity, processing 3,600 tons of solid waste daily and generating approximately 120 MW of clean, renewable electricity. The core of the thermal treatment process relies on a sophisticated reversible system. This system ensures the rapid drying and combustion of waste. Furthermore, the dynamic mechanical movements of the reversible system guarantee exceptional combustion efficiency, producing minimal carbon content from the remaining ash and maximizing the overall combustion energy output.

The facility prioritizes environmental safety and emissions control. Each thermal treatment unit features a dedicated flue gas treatment system and an advanced consolidation system. This system fully complies with Singapore’s Environmental Protection and Management Regulations of 2001. Key emission reduction processes incorporate non-catalytic selective reduction (SNCR) technology to lower nitrogen oxide (NOx) concentrations in flue gases. Additionally, a highly efficient dry catalytic fabric filtration system is designed to capture and extract dust particles, acid compounds, and other hazardous pollutants[15].

One of the most prominent sustainability features at the Tuas WTE facility is its combustion management, specifically bottom ash. Instead of being disposed of in landfills, it undergoes a recycling and stabilization process to extract ferrous and non-ferrous metals. The remaining ash is then processed into an environmentally friendly building material known as “news-side.” This material is used in recycling infrastructure projects such as roads and landfill sites, thus promoting a circular economy and achieving the goal of a waste-free landfill[15].

The table aims to provide a comprehensive evaluation of the waste-to-energy models that have been researched. This comparison highlights how different urban contexts and functional outcomes of infrastructure projects affect the process.

Design Criteria CopenHill
(Denmark)		 Tuas Nexus/Tuas One (Singapore)
Primary urban objective Social integration, recreation, and urban landmark. Industrial symbiosis, land optimization and resource recovery
Integration synergy Waste-to-energy mixed with public sports ( ski slope). Waste-to-energy co-located with water reclamation plant.
Byproduct innovation Clean steam rings for environmental awareness. NEWS and production for land reclamation and building .
Land allocation Compact footprint within a high-density city center . Highly optimized multi-level facility for land scarcity.

Based on the comparative data shown in the table, it is clear that sustainable engineering philosophies focus heavily on industrial-technological synergy to solve the problem of material and land scarcity, while the Danish city of Copenhagen prioritizes social and architectural integration and heavy infrastructure in public life based on recreational urban planning. Both strategies redefine the traditional concept of waste management, shifting burdens to economic models

Local Context and Project Site Analysis: The New Amra City (Amman)

Jordan is making significant strides towards transitioning from an economy based on resource extraction, manufacturing, and waste disposal to a circular economy. This economy relies on resource reuse, waste recycling, and reprocessing. The circular economy presents Jordan with a promising opportunity to achieve sustainable development, encompassing environmental commitments, economic growth, increased GDP, and job creation.

Regarding waste management, the most prominent feature of the waste management system is the collection and disposal method. Municipalities and the Greater Amman Municipality are responsible for collecting solid waste from residential areas and transporting it to the Ghabawi landfill, which receives waste from the capital, and the Al-Akeeder landfill in the north.

Recycling is currently limited to only 7% of waste, compared to 60% of biodegradable organic waste. Jordan is currently working to increase support for programs and projects that encourage sorting at the source and converting waste into energy. However, one of the most significant shortcomings in Jordan’s waste management is the heavy reliance on open landfills, along with structural and environmental challenges.

Population growth is placing immense pressure on infrastructure, and the primary drawback is the lack of sorting and recycling. The Kingdom relies on mixed waste collection, with organic waste constituting the largest percentage (63%), and depends on traditional landfills. The practice of burying waste and not utilizing it creates a significant burden, leading to groundwater and soil pollution and greenhouse gas emissions. There is also limited private sector participation in attracting major investments to convert waste into energy[16].

General Waste Generation and Composition Rates in Amman

Amman’s current population is 3 million. The average waste generation per person ranges from 0.6 to 1 kg/person/day, equivalent to an average design capacity of 0.8 kg. The total volume of waste in Jordan is expected to increase to 6.57 million tons by 2050, based on an estimated population growth of 22.5 million. The table below shows the proportions of solid waste components in Amman, representing the overall mix of waste generated in the city. This is essential for determining the economic and environmental viability of recycling processes[17].

Component Percentage (%) Nature and characteristics
Organic waste ( food scraps) 63,4% It represents the largest part and is characterized by a high humidity level.
Paper and cardboard 14,76% Recyclable and increasing in high-income areas
Plastic 13,57% Its proportion increases in industrial and poor areas.
Metals and cans 3,20% It is heavily concentrated in East Amman, reaching up to 12%, due to workshops and factories.
Glass 2,56% A biodegradable material with good recycling potential
Other miscellaneous waste 2,87% Includes textiles, wood, and various umbrellas

Site Selection Criteria

Despite the previous environmental indicators and challenges facing the solid waste management sector in Jordan, it has become necessary to move away from traditional solutions based on total landfilling to well-studied and smart engineering and architectural solutions. The (New Amra) project in Amman was chosen to be the first area to embody sustainability and environmental friendliness. Since the smart project is under study and implementation, which I will present with hypothetical statistics in the area, and based on precise planning and environmental parameters that serve sustainability goals, the strategic open location of the New Amra area is located in an expansion area and provides high flexibility for designing an integrated environmental facility.

Its proximity to the planning road network is located within a geographical route that facilitates the process of collecting waste from different areas and redirecting it. The diversity of the nature of the waste, as the site is close to the eastern and southern sides of Amman, the site receives a mixture of collecting residential organic and solid waste. The site will establish a waste station suitable for the New Amra area itself and the eastern and southern extensions.

Estimated and hypothetical design calculations for the new city of Amra

Given that the new city of Amra is a future city under development and expansion, and has not yet been fully implemented, the projections were based on a hypothetical planning model with projected target population (phase one)

For phase one, we assume the area will accommodate 250,000 people, and the average waste generation per capita, according to national studies in Amman, is 0.8 kg/person/day.

Equation for calculating the city’s total daily waste

Converting kilograms to tons

Total=200,000/1000=200 tons/day

Estimate of component sizes based on official Amman city proportions

The percentage is based on a hypothetical total of 200 tons/day, resulting in the calculation of the waste entering the factory daily:

Component Default percentage % Expected quantity (tons/day)
Organic waste (food scraps) 63% 126 tons/day
Paper and cardboard 15% 30 tons/day
Plastic 13,5% 27 tons/day
Metals, glass and other materials 8,5% 17 tons/day
Total 100% 200 tons/day

Adapting the power supply of the plant/station designed with the default outputs

The mechanical sorting line, with its conveyor belts and magnetic separators, is designed to accommodate any future population growth or peak, with an operational capacity of up to 250 tons/day. This includes 57 tons of plastic waste.

The biological recycling and composting unit, given that organic waste constitutes 126 tons/day, occupies the largest section of the station. It features anaerobic digesters and a mechanical aerobic composting units capable of handling large quantities.

The design aims to reduce landfill volume by 80-90%, leaving only non-organic materials for recycling as the final disposal method. This makes the city more sustainable.

Architectural Design Vision

The design vision for the project is to move away from traditional industrial facilities, which are merely places for waste disposal, towards a redesign of a vibrant green infrastructure that integrates with the future urban fabric of the new city of Amra. The design vision focuses on three axes:

The massing and site simulation through the ground architecture are inspired by the open land of Amra, and the design masses are on horizontal lines that are in harmony with the topography, thus reducing the visual impact Intelligent building orientation involves orienting architectural openings to maximize prevailing winds, while designing facades to deflect sunlight on heat-exposed sides.

Complete separation is maintained between the movement of trucks responsible for transporting waste and the path of employees and visitors. Operations that produce odors or emissions are confined within isolated and airtight concrete blocks under negative air pressure, while offices and educational facilities open green internal courtyards to provide a healthy and suitable working environment.

Sustainability and transforming the facility into an environmental landmark

The waste-to-energy project is self-sufficient, embodying the principle of sustainability and transforming the project into a net-zero energy facility. The project, with its rooftop terrace surrounded by gardens, is not limited to engineering; it also includes an environmental awareness and innovation center containing educational halls and elevated glass walkways that allow visitors and students to observe smart sorting and recycling processes.

How to Introduce Sustainable Home Cleaning Practices

By | | ,
Leave a comment

You may not be able to control the waste that happens outside of your home, but your home is your domain. You have some control over what happens there, and you can actively work to limit waste. In the area of home cleaning, you can conserve resources and ensure that wastage is minimized so that your impact on the environment is a positive one.

sustainable home cleaning

Limit Water Usage

One of the most egregious wastes that takes place when people clean their homes is in the amount of water they use up. Keep in mind that a hose will use far more water than a bucket. With a bucket of water to work from, you have greater control over the amount of water that you use. You can regulate your water wastage better and eliminate unnecessary use.

Some water can be used over and over again, particularly for tasks that don’t require extremely clean water. For instance, if you are mopping floors, you can use water that is classified as grey water, which would be leftover water from washing dishes or from another cleaning task that does not put harmful chemicals into the water. If you use safe cleaning supplies as you work, you may end up with grey water that can be reused. This is not water you would drink with or use to brush your teeth, but there are other uses for it that would allow you to reuse it and conserve precious resources, especially in times of drought.

Use Professional Cleaning Services

If you believe that you waste resources when cleaning, you may want to look into alternatives that would be less wasteful and more effective. One of those is expert home cleaning services, and you can use Dustbrook house cleaning to help you out. They will buy their cleaning supplies in bulk, saving resources by using larger containers. They will clean more efficiently, which uses fewer resources and conserves water and cleaning supplies. They will know shortcuts to ensure that the cleaning gets done faster, so less power is used as well.

One of the big ways that professional cleaners will help you reduce environmental impact is when they perform pressure washing for you. If you have never done this kind of cleaning task before, then you may waste lots of water and may be inefficient in the use of precious resources. Because of the expert cleaners’ experience, they can do the work much faster and use less resources.

In many ways, professional cleaners can cut down on used resources, make the work go faster, and help you be more environmentally friendly. They can make the work much easier for you as well, and that’s a big help when your schedule is busy or you just lack energy.

Reuse the Same High Quality Tools

Another area where many homeowners tend to waste money and resources is in the kinds of cleaning tools that they buy. It is tempting to purchase mops, brooms, scrubbing pads, and other tools for cleaning that are cheap. They cost less upfront, so it often makes financial sense from the outset to buy these tools. But what you may not realize is that by doing this, you pay more over time and you use up valuable and limited resources.

Consider the impact of buying the same low quality, cheap cleaning tools over a period of years. You use up the scrubbing pads quickly, leading you to have to replace them after just a few weeks of use. So, you buy new ones over and over again, at a cheap price but at a cost that adds up. Now, consider buying stronger and more expensive scrubbing pads and using them repeatedly month after month. They last longer and work better. They don’t fall apart as fast, so you can keep using them and experience less frustration as well.

We want to encourage you to buy cleaning supplies that will last and that can be used repeatedly for long periods of time. These cost more initially, but your cost savings over time is going to be tremendous. Plus, you will use fewer resources by doing this. It costs more for manufacturing companies and causes them to use more resources to create multiple copies of the same cheap clearing tool than it does for them to make one product that is used over and over.

Your buying choices do matter to the environment, and if you are careful and thoughtful, you can directly impact how much work and how many resources go into the things that you buy. If you purchase only tough, reusable items and stay away from cheap, one-time use products, you will have a positive impact on the environment. That impact may be small, btu it can have a ripple effect as you influence your friends and family to do the same.

Use Safe, Natural Cleaning Solutions

When you buy spray cleaners, disinfectants, and other cleaning supplies that use chemicals, do you think about what those chemicals are doing to the environment? Parabens, aerosols, and other chemicals that are known to hurt the environment are easily found and purchased in your average store. These make for decent cleaners simply because they can be easy to use and can also be very effective, but their negative impact on the environment needs to be recognized.

eco-friendly cleaner at work

If you use harmful chacmas to clean with, they can leech into the environment and hurt the plant life and the atmosphere. If you choose natural and safe cleaners instead, you will cut down on your environmental impact and preserve the immediate environment around you. These cleaners also tend to be better for your health and the health of your family and pets. They can be a little tough to find and may not be as readily available, but the difference they make cannot be overstated.

Your buying choices are very important when it comes to your impact on the environment. You can clean your house effectively and conserve resources by making smart decisions, and we hope that this article helps you to do that.

Beyond the Blue Economy: The Rise of Integrated Circular Coastal Systems

By | | ,
Leave a comment

For decades, the Blue Economy has inspired governments, industries, and researchers to rethink humanity’s relationship with the oceans. By promoting sustainable fisheries, aquaculture, maritime transport, offshore renewable energy, coastal tourism, and marine biotechnology, it has demonstrated that economic growth and environmental stewardship can coexist [1–3]. Today, the Blue Economy contributes significantly to global development while supporting millions of jobs and generating substantial economic value across coastal regions. Yet, despite its remarkable achievements, the concept is reaching a new crossroads. The environmental challenges of the twenty-first century extend well beyond the sustainable exploitation of marine resources. They now encompass water scarcity, climate change, energy security, critical raw material supply, marine pollution, and ecosystem degradation issues that cannot be addressed independently.

blue economy

Every day, coastal infrastructure around the world produces enormous quantities of freshwater, renewable electricity, treated wastewater, concentrated desalination brine, industrial gases, organic residues, and marine biomass. Ironically, these valuable resources continue to be managed as separate outputs of independent sectors. Desalination plants focus on freshwater production while discarding concentrated brine. Wastewater treatment facilities remove pollutants before discharge. Renewable energy installations generate electricity without systematic integration with water infrastructure. Green hydrogen projects are often planned independently from desalination systems, despite their dependence on high-quality water. This fragmented approach reflects the industrial logic of the twentieth century, where each facility was designed to optimize a single objective. It is becoming increasingly inadequate for addressing the interconnected challenges of climate resilience, resource efficiency, and sustainable development [4,5].

The urgency of adopting a more integrated approach is reflected in global trends. Nearly 40% of the world’s population lives within 100 kilometres of the coast, where urbanization, industrial development, tourism, agriculture, and ecosystem conservation compete for increasingly limited water and energy resources [2]. At the same time, freshwater demand is projected to increase by 20–30% by 2050, while climate change is intensifying droughts, sea-level rise, and coastal ecosystem degradation [2,13]. These converging pressures highlight a simple reality: future coastal infrastructure must simultaneously deliver water security, renewable energy, resource recovery, and ecosystem resilience rather than addressing each challenge separately.

The next evolution of the Blue Economy will therefore not be driven by a single breakthrough technology. Instead, it will emerge from the intelligent integration of existing technologies into regenerative coastal systems. The future unit of innovation is no longer the desalination plant, the wastewater treatment facility, the hydrogen electrolyser, or the aquaculture farm. It is the coastal system itself.

This emerging paradigm may be described as Integrated Circular Coastal Systems (ICCS); a framework in which freshwater, renewable energy, materials, nutrients, biological resources, and ecosystem services continuously circulate through interconnected infrastructures that maximize resource efficiency while minimizing environmental impacts. Unlike conventional coastal development, where individual sectors operate independently, ICCS promotes industrial symbiosis, whereby the output of one process becomes the input of another. Wastewater becomes a water resource. Desalination brine becomes a source of strategic minerals. Organic residues become bioenergy or fertilizers. Renewable electricity simultaneously powers desalination, electrolysis, and resource recovery processes. The objective is no longer simply to reduce environmental impacts but to create regenerative coastal economies that continuously recover value from every resource stream.

Few technologies illustrate this transformation better than seawater desalination. Once considered an expensive solution reserved for extremely water-scarce regions, desalination has evolved into one of the world’s fastest-growing sources of freshwater. More than 22,000 desalination plants currently produce over 100 million cubic metres of freshwater every day, supplying drinking water to hundreds of millions of people worldwide [6]. Continuous improvements in reverse osmosis membranes, energy recovery devices, and process optimization have significantly reduced both energy consumption and operating costs over the past two decades [7]. As renewable electricity becomes increasingly available, desalination is progressively evolving into a lower-carbon solution capable of strengthening long-term water security.

However, desalination also exposes the limitations of linear infrastructure. Conventional plants produce two outputs: freshwater and concentrated brine. While freshwater is highly valued, the brine is generally discharged back into the marine environment, where localized increases in salinity may affect sensitive ecosystems [6]. From the perspective of a Circular Blue Economy, this represents an untapped opportunity rather than an unavoidable waste stream. Brine contains commercially valuable elements including sodium, magnesium, potassium, calcium, bromine, and trace quantities of lithium and other strategic minerals that are becoming increasingly important for batteries, renewable energy technologies, and advanced manufacturing [6,8].

Historically, desalination facilities have been evaluated almost exclusively according to freshwater production and operational efficiency. Future plants should instead be assessed according to the total value they generate. Freshwater production, mineral recovery, renewable energy integration, recovered industrial gases, avoided greenhouse gas emissions, and ecosystem protection should all become indicators of performance. In a truly circular coastal economy, success is measured not simply by the volume of freshwater produced, but by the overall value created from every cubic metre of seawater processed.

Green hydrogen represents another cornerstone of this new generation of coastal systems. As countries accelerate their transition toward carbon neutrality, hydrogen produced through renewable-powered electrolysis is emerging as one of the most promising solutions for decarbonizing sectors that are difficult to electrify, including steel production, fertilizers, shipping, aviation, and heavy industry [9,10]. While discussions often focus on renewable electricity, much less attention has been paid to the water required for electrolysis. Producing one kilogram of hydrogen requires approximately nine litres of highly purified water. Although this volume is modest compared with agricultural or municipal demand, reliable access to high-quality water becomes essential as hydrogen production expands to industrial scales [9].

Rather than considering this requirement as a constraint, coastal regions should view it as an opportunity. Renewable-powered desalination can provide a sustainable source of ultrapure water while simultaneously strengthening water security for surrounding communities. Solar and wind electricity can power both reverse osmosis systems and electrolyzers, creating integrated facilities capable of producing freshwater and green hydrogen from the same renewable energy source. Even the oxygen generated during electrolysis, often regarded as a secondary product, can be recovered for hospitals, aquaculture, wastewater treatment, and industrial applications, further improving overall resource efficiency [9,10]. Instead of functioning as isolated facilities, desalination plants and hydrogen production units become complementary components of a single circular coastal system.

This transformation also reflects a broader evolution in industrial design. Coastal infrastructure should no longer be conceived as facilities delivering one product, but as multi-resource platforms capable of simultaneously producing water, clean energy, recovered materials, industrial gases, and environmental services. Such integration increases economic resilience while reducing waste generation and greenhouse gas emissions.

Digital technologies will play a decisive role in enabling this transition. Artificial intelligence can optimize membrane operation, predict fouling before it occurs, and reduce electricity consumption in desalination plants. Digital twins allow engineers to simulate the behaviour of integrated coastal infrastructures under different operating and climate scenarios, while satellite observations and remote sensing technologies provide continuous information on water quality, coastal erosion, and ecosystem health. Together, these technologies create the intelligence necessary to coordinate increasingly complex interactions between water, energy, materials, and ecosystems, transforming conventional infrastructure into adaptive and resilient resource systems.

The principles of circularity extend well beyond desalination and hydrogen production. Around the world, wastewater treatment plants are progressively evolving into Water Resource Recovery Facilities (WRRFs) capable of generating reclaimed water, renewable biogas, phosphorus, nitrogen fertilizers, and biosolids rather than simply treating wastewater before discharge [11]. This transition represents one of the clearest examples of the circular economy in practice. Instead of considering wastewater as a liability, it becomes an alternative source of freshwater, nutrients, renewable energy, and industrial raw materials.

The same philosophy applies to fisheries, aquaculture, and marine biotechnology. Organic residues generated by fish processing industries can be converted into animal feed, biofertilizers, collagen, chitosan, and other high-value bioproducts. Marine algae are increasingly recognized as versatile biological resources capable of producing pharmaceuticals, cosmetics, functional foods, biodegradable plastics, biofuels, and sustainable aviation fuels [12]. Their ability to absorb nutrients and carbon dioxide further strengthens their role within circular coastal systems by simultaneously contributing to wastewater polishing, carbon sequestration, and biomass production.

Similarly, desalination brine is gradually evolving from an environmental challenge into an economic opportunity. Recent advances in selective membranes, electrodialysis, membrane distillation, electrochemical separation, adsorption technologies, and advanced crystallization have significantly improved the feasibility of recovering valuable compounds from concentrated saline streams [8]. Magnesium, bromine, potassium, sodium salts, and, potentially, lithium are increasingly attracting attention as strategic resources needed for batteries, renewable energy technologies, lightweight alloys, pharmaceuticals, and specialty chemicals. Although several recovery technologies remain at pilot scale, they illustrate a profound change in perspective: future desalination plants may become integrated mineral production facilities rather than simple freshwater factories.

Perhaps the most significant implication of this emerging paradigm is that coastal competitiveness will increasingly depend on resource circularity rather than resource abundance alone. Regions capable of recovering materials, reusing water, integrating renewable energy, restoring ecosystems, and creating industrial symbiosis will enjoy substantial economic and environmental advantages over those relying on conventional linear infrastructure. Competitive coastal economies of the future will therefore not necessarily be those endowed with the greatest natural resources, but those managing them most intelligently.

This systems perspective also changes how success should be measured. Traditional performance indicators such as cubic metres of freshwater produced, megawatts generated, or tonnes of hydrogen exported, capture only part of the value created by coastal infrastructure. Integrated circular coastal systems require broader indicators that include water reuse rates, renewable energy integration, resource recovery efficiency, avoided carbon emissions, ecosystem restoration, biodiversity protection, and economic value generated from recovered materials. Such multidimensional evaluation better reflects the true contribution of circular infrastructure to sustainable development.

Increasingly, the objective is no longer to optimize individual facilities but to optimize the interactions among them. Water supports energy production. Energy enables desalination. Brine becomes a source of minerals. Wastewater supplies irrigation and industry. Organic residues produce renewable energy and fertilizers. Marine ecosystems provide carbon sequestration, biodiversity, fisheries, and coastal protection. Every resource flow reinforces another, creating a regenerative network that is significantly more resilient than isolated infrastructure.

The Mediterranean region is uniquely positioned to become a global laboratory for this new model of coastal development. Although the Mediterranean Sea represents less than 1% of the world’s ocean surface, it hosts nearly 10% of global marine biodiversity while supporting more than 500 million people along its coastline [13]. At the same time, the region is recognized as one of the world’s climate change hotspots, warming faster than the global average and facing increasing water scarcity, coastal erosion, biodiversity loss, and growing competition among agriculture, industry, tourism, and urban development for limited natural resources [13]. These interconnected challenges cannot be solved through isolated sectoral policies. They require integrated solutions that simultaneously strengthen water security, accelerate the energy transition, recover valuable resources, and restore coastal ecosystems.

This is precisely where Integrated Circular Coastal Systems can make a transformative contribution. Rather than planning desalination plants, wastewater treatment facilities, renewable energy projects, hydrogen hubs, ports, and industrial zones independently, coastal territories should be designed as interconnected resource systems where water, energy, materials, nutrients, and ecosystem services circulate continuously. Such an approach increases resource productivity while reducing environmental pressures and strengthening climate resilience.

Among Mediterranean countries, Algeria possesses exceptional assets to pioneer this transition. With more than 1,600 km of coastline, one of the highest solar irradiation levels in the world, expanding seawater desalination infrastructure, ambitious renewable energy programmes, and growing interest in green hydrogen exports, the country has many of the ingredients required to develop integrated circular coastal systems. Rather than viewing desalination simply as a source of drinking water, Algeria has the opportunity to transform future plants into multifunctional facilities producing freshwater, ultrapure water for electrolysis, recovered minerals, industrial salts, oxygen, and valuable by-products. Coupled with wastewater reuse, marine biotechnology, and ecosystem restoration, such infrastructure could significantly improve both environmental sustainability and economic competitiveness.

This integrated vision is fully aligned with the Sustainable Development Goals, particularly those related to clean water (SDG 6), affordable and clean energy (SDG 7), sustainable industry (SDG 9), sustainable cities (SDG 11), responsible consumption and production (SDG 12), climate action (SDG 13), and life below water (SDG 14) [2]. It also complements emerging international strategies promoting circular economy principles, industrial symbiosis, nature-based solutions, and low-carbon development pathways [14,15].

However, achieving this transition requires more than technological innovation. It demands new governance models capable of breaking down institutional barriers between water authorities, energy agencies, environmental regulators, industrial operators, and coastal planners. Future investment strategies should encourage projects that maximize resource synergies rather than optimizing individual sectors in isolation. Research institutions and universities also have an essential role to play by developing interdisciplinary knowledge that bridges engineering, environmental science, economics, ecology, and public policy.

Ultimately, the Circular Blue Economy should not be understood simply as the application of circular economy principles to marine sectors. It represents a broader transformation in how coastal territories are conceived and managed. The objective is no longer merely to reduce environmental impacts but to create regenerative systems in which every drop of water, every unit of renewable energy, every kilogram of recovered material, and every ecosystem service contributes to long-term resilience and prosperity.

The Blue Economy has already transformed our understanding of sustainable ocean development. Its next evolution should move beyond the sustainable exploitation of marine resources toward the intelligent integration of coastal systems. Future competitiveness will no longer depend solely on access to natural resources but on the capacity to circulate them efficiently through interconnected infrastructures.

The twentieth century built coastal infrastructure to extract resources from the sea. The twenty-first century must build coastal systems that regenerate them. The future of coastal development will not be defined by isolated desalination plants, hydrogen facilities, wastewater treatment plants, or renewable energy projects, but by the intelligence with which these systems interact. The greatest wealth of the oceans is no longer simply what they contain, it is the capacity of coastal societies to circulate water, energy, materials, nutrients, and ecosystem services within resilient and regenerative systems. This is the true promise of the next generation of the Blue Economy.

The Rationale for Making a Switch to Circular Economy

By | | ,
3 Comments

All forms of wealth and security, including climate stability, biodiversity, resource availability, soil fertility, air and water purity and health, are depleted by the systemic error of running a linear economy. Linear economics consumes the basis for future growth so what is now growing fastest is unproductive activity, inactivity and instabilities. The credit crunch marks the withdrawal of faith in growth-as-usual and any reliable revival of growth and prosperity requires a switch of vision.

Circular Economics

The future for growth is circular economics where more economic activity would mean a faster pace of change away from waste-making and towards looking after the world and all its inhabitants. This would preserve and regenerate material value, co-operation and natural capital instead of losing it, so growth would work to build the basis for more growth.

Today this may appear idealistic. Yet if circular economics was already practiced, and people were accustomed to prosperity based on resource security, then any proposal to adopt an exploitive self-defeating vision would be laughable.

Promise of Precycling

Economic dependence on waste is perpetuated by managing waste primarily as an addiction to disposal, “how can we get rid of all this junk?” The ‘waste hierarchy’ (reduce, reuse, recycle, then dispose) that has been available since 1975 is commonly quoted but in practice the bulk of effort and funding provides for continuing long-term disposal to ecosystems (by landfill, waste-burning and pollution).

The waste hierarchy is being used backwards and no nation has yet attempted to create the incentives for an economy that grows from the work done to end waste dumping and implement circular economics. This is achievable with the concept of ‘precycling’ originally used for public waste education.

Precycling is applicable throughout an economy and may be understood as action taken to prepare for current resources to become future resources. The ‘pre’ prefix emphasises that this cannot be arranged after something becomes waste; it must be done beforehand. The scope of action extends far beyond recycling, to creating the economic, social and ecological conditions for all resources to remain of use to people or nature.

Precycling Insurance

A simple economic tool is available to switch from linear to circular economics and from dumping waste to dumping the habit of wasting. This tool internalises diverse externalities efficiently within markets by paying the price of preventing problems instead of the larger or unaffordable price of not preventing them.

Precycling insurance is an extension of the EU WEEE Directive’s ‘recycling insurance’ from just recycling to all forms of preventing all products becoming waste in any ecosystem. This allows a single economic instrument to work with the issues at every stage of product life-cycles. Significant producers would be obliged to consider the risk of their products ending up as waste in ecosystems and to retain responsibility for insuring against that risk.

Life Insurance for Products and Planet

Precycling insurance is a form of regulation to be set-up in every nation but not centrally planned. The volume of regulation can be cut but its effectiveness drastically boosted. For example, emissions can be cut rapidly with no need for any further ineffectual negotiations about capping. Unlike taxes, the premiums from precycling insurance would not be handled by governments (whose role would be to legislate, monitor and ensure full public transparency).

circular-economy

Unlike conventional insurance, the premiums would not be collected up and then paid out following (potentially irrecoverable) planet crunch shocks. Premiums would be distributed by insurers and invested preventively throughout society, to cut the risk of resources being lost as wastes.

Support would be provided for the dialogue, understanding, participation, capabilities, designs, efficiencies, facilities and ecological productivity needed to return used matter as new resources for people and for nature. Today’s resources would feed tomorrow’s economy.

A Free Market in Harmony with Nature

Precycling insurance would switch the power of markets to reversing the planet crunch. The speed and scale of change would exceed the expectations of all who are accustomed to ineffectual controls designed to make markets less-bad. All market participants (such as buyers, sellers, investors and governments) would adapt their decisions to the new incentives, profiting by addressing actual needs rather than superficial consumerist wants.

Precycling

Producers would remain free to choose how to meet customers’ needs without waste, and even free to continue making wasteful products, in competition with other producers cutting their costs (including precycling insurance costs) by cutting their product’s waste risk. Economic growth would no longer be a competitive scramble between people rushing to acquire and discard ever more resources from an every-shrinking stock. The economy would prosper in harmony, rather than in conflict, with nature.

Shrinking Material and Energy Demands

The material requirements of today’s linear economy would rapidly shrink since the new incentives would lead to the most needs being met with the least materials moved the least distance and then regenerated rather than dumped. The energy requirements of today’s linear economy would rapidly shrink since a smaller material flow with higher quality materials closer to where they are needed requires less energy to process.

Shrinking energy dependence is the key to energy security, economic recovery, climate restabilisation and prevention of conflict over diminishing non-renewable resources. The resource and energy efficiency of circular economics makes it realistic to plan the necessary reductions in GHG concentrations.

Waste-to-Energy Pathways: An Overview

Waste-to-energy is the use of modern combustion and biological technologies to recover energy from urban wastes. The conversion of waste material to energy can proceed along three major pathways – thermochemical, biochemical and physicochemical.

Thermochemical conversion, characterized by higher temperature and conversion rates, is best suited for lower moisture feedstock and is generally less selective for products. On the other hand, biochemical technologies are more suitable for wet wastes which are rich in organic matter.

Waste-to-Energy

1. Thermochemical Conversion of Waste

The three principal methods of thermochemical conversion of MSW are combustion (in excess air), gasification (in reduced air), and pyrolysis (in absence of air). The most common technique for producing both heat and electrical energy from wastes is direct combustion. Combined heat and power (CHP) or cogeneration systems, ranging from small-scale technology to large grid-connected facilities, provide significantly higher efficiencies than systems that only generate electricity.

Combustion technology is the controlled combustion of waste with the recovery of heat to produce steam which in turn produces power through steam turbines. Pyrolysis and gasification represent refined thermal treatment methods as alternatives to incineration and are characterized by the transformation of the waste into product gas as energy carrier for later combustion in, for example, a boiler or a gas engine. Plasma gasification, which takes place at extremely high temperature, is also hogging limelight.

2. Biochemical Conversion of Waste

Biochemical processes, like anaerobic digestion, can also produce clean energy in the form of biogas which can be converted to power and heat using a gas engine. Anaerobic digestion is the natural biological process which stabilizes organic waste in the absence of air and transforms it into biofertilizer and biogas.

Anaerobic digestion is a reliable and well-proven technology for the treatment of wet, organic waste.  Organic waste from various sources is biochemically degraded in highly controlled, oxygen-free conditions circumstances resulting in the production of biogas which can be used to produce both electricity and heat.

Anaerobic digestion is a reliable technology for treatment of organic fraction of MSW

In addition, a variety of fuels can be produced from waste resources including liquid fuels, such as ethanol, methanol, biodiesel, Fischer-Tropsch diesel, and gaseous fuels, such as hydrogen and methane. The resource base for biofuel production is composed of a wide variety of forestry and agricultural resources, industrial processing residues, and municipal solid and urban wood residues. Globally, biofuels are most commonly used to power vehicles, heat homes, and for cooking.

3. Physico-chemical Conversion of Waste

The physico-chemical technology involves various processes to improve physical and chemical properties of solid waste. The combustible fraction of the waste is converted into high-energy fuel pellets which may be used in steam generation. The waste is first dried to bring down the high moisture levels. Sand, grit, and other incombustible matter are then mechanically separated before the waste is compacted and converted into fuel pellets or RDF.

Fuel pellets have several distinct advantages over coal and wood because it is cleaner, free from incombustibles, has lower ash and moisture contents, is of uniform size, cost-effective, and eco-friendly.
