Recycling Prospects in Saudi Arabia

The concept of waste recycling has been getting increasing attention in Saudi Arabia in recent years. The country produces around 15 million tons of municipal solid waste each year with an average daily rate of 1.4 kg per person. This rate is projected to double (30 million tons per year) by 2033 with current annual population growth rate of 3.4%. The major ingredients of Saudi Arabian municipal solid waste are food waste (40-51%), paper (12-28%), cardboard (7%), plastics (5-17%), glass (3-5%), wood (2-8%), textile (2-6%), metals (2-8%) etc. depending on the urban activities and population density of studied region. Prevalent … Continue reading

The Unending Benefits of Recycling

Recycling is the process in which used or abandoned materials from our everyday waste is converted into new products. Items that can be recycled include; glass, paper, plastics and various metals.  The process of recycling involves waste segregation after collection, processing the recyclable waste and finally manufacturing products from the waste thus processed. Why Do We Need Recycling? Manufacturing products involves obtaining raw materials from various sources. Raw materials may be from forests or mines. They are then transported to the place of manufacture usually by land or sea, which is an energy consuming process. Procurement of raw materials and their … Continue reading

A Holistic Approach to Tackling Food Waste Problem in Qatar

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 … Continue reading

Advancements in Tire Shredding: Enhancing Tire Disposal Efficiency

Disposing of old tires is a real challenge, especially considering its link to broader issues such as waste management and environmental care. With growing global concern, finding efficient ways to handle used tires is more crucial than ever. One approach gaining popularity is tire-shredding, a practical method to deal with tire waste that also minimizes environmental impact. Fortunately, the tire-shredding techniques of today have undergone numerous transformations, mainly owing to technological advancements. These improvements aim to make the tire shredding process more efficient, sustainable, and less damaging to the environment. This article explores these technological advancements in-depth, highlighting how they … Continue reading

Analysis of a Composting Facility

The composting process is a complex interaction between the waste and the microorganisms within the waste. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and actinomycetes. Actinomycetes are a form of fungi-like bacteria that break down organic matter. The first stage of the biological activity is the consumption of easily available sugars by bacteria, which causes a fast rise in temperature. The second stage involves bacteria and actinomycetes that cause cellulose breakdown. The last stage is concerned with the breakdown of the tougher lignins by fungi. The composting process occurs when biodegradable waste is piled together … Continue reading

Making a Switch to Circular Economy

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 … Continue reading

The Popular Methods for Aluminium Recycling

The demand for aluminium products is growing steadily because of their positive contribution to modern living. Aluminium is the second most widely used metal whereas the aluminum can is the most recycled consumer product in the world. Aluminium finds extensive use in air, road and sea transport, food and medicine, packaging, construction, electronics and electrical power transmission. The excellent recyclability of aluminium, together with its high scrap value and low energy needs during recycling make aluminium highly desirable to one and all. The global aluminium demand is forecasted to soar to nearly 70 million tons by 2020 from around 37 … Continue reading

Fuel Pellets from Solid Wastes

Municipal solid waste is a poor-quality fuel and its pre-processing is necessary to convert it into fuel pellets to improve its consistency, storage properties, handling characteristics, combustion behaviour and calorific value. Technological improvements are taking place in the realms of advanced source separation of MSW, resource recovery and production of MSW fuel pellets in both existing and new plants for this purpose. There has been an increase in global interest in the preparation of MSW fuel pellets or Refuse Derived Fuel (or RDF) so let us take a close look at this interesting alternative fuel. Pelletization of Muncipal Solid Waste … Continue reading

Recycling of PET Plastic Bottles

Like all other modern urban centers, the Middle East also faces challenges in environmental protection due to tremendous tonnage of plastic waste produced in different forms. The gross urban waste generation from Middle East countries exceeds 150 million tons per annum, out of which 10-15 percent is contributed by plastic wastes. The burgeoning population, growing consumption, and an increasing trend towards a “disposable” culture, is causing nightmares to municipal authorities across the region and beyond. Plastic consumption has grown at a tremendous rate over the past two decades as plastics now play an important role in all aspects of modern … Continue reading

The Significance of E-Waste Management

E-waste is the fastest growing waste stream, and its disposal is a major environmental concern in all parts of the world. More than 50 million tons of e-waste is generated every year with major fraction finding its way to landfills and dumpsites. E-waste comprises as much as 8% of the municipal solid waste stream in rich nations, such as those in GCC. Globally only 15 – 20 percent of e-waste is recycled while the rest is dumped into developing countries. However, in the Middle East, merely 5 percent of e-waste is sent to recycling facilities (which are located in Asia, … Continue reading
