This planet is all we have and, unless we start properly looking after it, we can lose everything from ecosystems to all resources, including our most precious – freshwater. However, selective recycling isn’t the only way to reduce pollution and help the planet.
Owning a pet is a great responsibility but also a challenge since most of their accessories and food are made of plastic or packed in it. As one of the most vocal advocates of sustainability in the Middle East, EcoMENA pleads for a more responsible life and wishes to share some easy tips on how to look after the planet while still raising a healthy and happy pet.
Adopt, don’t shop
Although you’ll rarely see stray dogs and cats wandering on the streets of Middle Eastern countries, there is no doubt that many animals are still abandoned by their owners in shelters, because they can no longer provide for them.
If you want to make Earth a better place, start by adopting a pet that needs love and affection instead of spending small fortunes on pure-breed cats and dogs. Remember that whenever you’re adopting from a shelter, you save a life and you gain a new friend or a family member.
Adopting is an economic-friendly solution for all animal lovers, and we assure you there are plenty of adorable kittens and puppies waiting for their forever home.
Opt for sustainable pet food
We know that you want your best for your pet, and this includes paying extra for organic food but why settle for small packages that only add to the global plastic waste? Choose food brands that are committed to making a positive change, and this includes selling their products in environmentally-friendly and biodegradable packages. Check out Nutra Thrive Cat reviews to find the best nutrition for your pet.
If that’s not possible, another way to reduce waste would be to buy larger quantities. Store the extra food in glass recipients or paper bags, in cool and dry places. This will help preserve the flavor and the taste of the food as months pass by. The same goes for resealable bags that won’t alter the food’s properties.
Why spend hundreds of dollars on pet treats and contribute to more waste when you can bake or make your own? Various online tutorials will teach you how to make delicious snacks, step-by-step.
What’s even better is that you can bake tasty recipes with ingredients that you already have at home and use for your regular meals. As long as the ingredients are organic and designed for dog or cat consumption, you can create a wide array of treats for any occasion.
If spending extra time in the kitchen isn’t your thing, you can always adapt your dinner recipes to the needs of your pet. Steaks are a delicious meal for all your family members and, as long as you don’t use any seasoning or sauces for your dog’s piece, you will have its snack ready in a minute.
Cats love tuna and any other type of fish, so make sure to grill one for them. The same goes for poultry, turkey, and any other type of meat. Grilled, baked or steamed meat represents a healthy choice for all your family members, including your pawed friends.
Eco-friendly accessories and grooming products
If you want to reduce plastic waste, you should also consider opting for green and eco-friendly pet grooming products packaged in biodegradable bottles. As for leashes, collars, kennels, and even outfits, why not opt for second-hand products?
Many animal lovers tend to buy all the accessories and products they can find for their pets but don’t end up using more than 20-30% of them. Luckily, there are plenty of online forums and even physical stores where you can shop for unused products at discount prices. Reusing and recycling are two of the main principles for a cleaner world, so why not adopt this lifestyle?
Apart from finding unique accessories and cool new outfits for your pooch, you will also save money and prevent waste
Invest in pet-proof products
Cats, dogs, and ferrets are all wonderful creatures but they can end up tearing your house apart and breaking your most valuable belongings. If you’re serious about adopting a new pet, you must know how to “animal-proof” your house to prevent buying new shoes, clothes, electronics, and accessories every other month.
Keep all your shoes and clothes in the closet, on high shelves where your pet cannot reach them and replace some of your tableware with plates, glasses, and cups made of metal or other strong materials. You should do the same with your trash bin if you don’t want your animals to move it from one place to another and spill all its content on the floor.
Before the current pandemic that the world is battling, East Africa and neighbouring regions of the globe experienced the biggest locust infestation in the past 70 years. That event was devastating. Then the Covid-19 pandemic started to move across the globe. And just as a viral plague can resurface if adequate measures are not taken and sustained for a long enough period of time to interrupt the spread of the virus, the locusts have returned. The locust plague has reappeared in East Africa and is said to be 20 times the strength of the earlier infestations.
The Fight for Food
Billions of young, hungry locusts are swarming across the continent from their breeding grounds in Somalia. As the summer season is fast approaching, fresh, young vegetation is starting to flourish with the help of the seasonal rains.
Rural people are in a double whammy situation, needing to protect their crops by whatever means are available while the spread of coronavirus is over-shadowing them as well. The fight for food will win out over the fight for prevention of the virus. Its another catch-22 where humanity suffers from infection or dies of starvation. These are impossible situations in which to have to make choices. The most destructive impact obviously wins out.
The nations affected include Kenya, Ethiopia, South Sudan. The swarms have also been sighted in Djibouti, Eritrea, Tanzania and the Congo.
Village farmers have very limited means of defeating the locusts and driving the swarms off their lands onto neighbouring lands. The farmers even resort to bang metal pots and pans, throwing stones, and whistling and shouting. Others merely watch and stare. Their main crop is a starch-food, cassava that helps ward off the village people from starvation.
The Role of Climate Change
The UN Food and Agricultural Organisation (FAO) attributes the locust infestations partly due to the change in the regional climate. In other words, climate change. New swarms keep appearing because of the ideal breeding conditions. These favourable conditions could last through May, meaning that more swarms of the locusts could appear during the harvest months, June and July.
To counterattack the locust swarms, the UN is appealing for financial aid to be freed up and made available for combat measures. The young or juvenile locusts are far more voracious that the mature adult locusts. The scientists, satellite information analysts to be precise, at the Nairobi-based Climate Prediction and Application Centre are analyzing satellite imagery.
The Difficult Fight Against Locust Swarms
The ability to fight the swarms with the spraying of pesticide is severely restricted by the Covid-19 regulations that have significant restrictions on travel and delivery of the much needed pesticides. The dilemma is which infestation takes precedence. Field verification of the severity of the locust swarms is also hampered majorly. Overall, the world is stretched to its limits dealing with the global pandemic that other regional plagues are not receiving the attention that they also need in terms of combating the devastating situation.
The extent of these swarms is vast, that aerial top-spraying is the best option but there are border control issues as well as the challenges of securing aerial flight crews and delivery of pesticides via road or air. There is major concern, that the importation of pesticides from suppliers around the globe is also hampered by the interruptions in international cargo shipments during this pandemic.
Bottom Line
The food security in East African nations are seriously threatened by crop devastation, loss of pasture cover used as fodder for livestock and forest cover could also be denuded. The final note of gloom is that these swarms are appearing in regions previously not subjected to locusts.
The solutions are not obvious while the situation is dire for all concerned individuals. Researchers prefer to write on situations and propose solutions or at least recommendations. In this case, nature is proving stronger humankind in its ability, not to control, but even to work with nature.
تبذير الطعام له آثار بيئية واقتصادية وكذلك الاجتماعية. ارتفاع نصيب الفرد من الدخل والإنفاق، ومستويات المعيشة، القدرة على تحمل التكاليف و اللامبالاة تجاه الطعام كلها عوامل لها تأثير سلبي كبير على مواردنا المحدودة. في مراكز التسوق والمطاعم على سبيل المثال ، من الشائع أن نرى كميات متراكمة من الطعام غير المستهلك كليا أو جزئيا. للأسف، الرفاهية تؤدي إلى تفشي توليد النفايات الغذائية في جميع أنحاء الشرق الأوسط، وخاصة دول مجلس التعاون الخليجي.
خطورة الوضع يمكن قياسها من كون أن أكثر من 300 طن من النفايات الغذائية يتم توليدها يوميا في البحرين وهذا يشكل حوالي 11٪ من إجمالي نفايات البلدية . كل هذه النفايات يتم تفريغها في حاويات و جمعها من قبل عمال البلدية ونقلها إلى مكب عسكر الواقع على بعد نحو 25 كيلومترا من المدينة.
الناس في الشرق الأوسط يجب أن تعي أننا نستورد معظم المواد الغذائية ,ورميها بلا مبالاة في القمامة غير مقبول بتاتا. تشير التقديرات إلى أن حوالي ربع المواد الغذائية التي يتم شراؤها تتعفن وتجد طريقها إلى سلة المهملات حتى قبل استخدامها أو تناولها.
الناس يميلون إلى شراء أكثر مما يحتاجون أو ما يمكنهم استهلاكه وغالبا ما تترك الوجبات نصف مأكولة، و هذا سلوك غير لائق. ترك الطعام هو عادة سيئة تؤدي إلى المزيد من الهدر حيث أن المواد الغذائية لا يتم الاستفادة منها بشكل كامل وفعال وينتهي بها المطاف في صناديق القمامة. وبالإضافة إلى ذلك، فإن أكثر مشاهد هدر الطعام نراها في المأدبات و الولائم (البوفيه)، حيث الخيارات من أطباق كثيرة و الكميات غير محدودة. رد فعلنا أو موقفنا من طعامنا يجب أن يكون “اخذ فقط ما يمكنك أن تأكل.
ارتفعت تكلفة الأطعمة النيئة و المطبوخة بشكل حاد في السنوات الأخيرة، الامر الذي يشكل عبئا إضافيا على ميزانيات البيوت و أرباب الأسر الذين يرزحون تحت تكاليف أخرى مرتفعة من معيشة وسكن ودواء ونقل الخ. تجنب تبذير الأطعمة هو مهمتنا الاولى لنساعد على التقليل من كمية النفايات القابلة للتحلل عضويا الذاهبة إلى صناديق القمامة ومن ثم إلى مكب النفايات. وبالإضافة إلى ذلك، إذا قمنا بجمع فضلات الطعام، فإننا سنزيل جزأ كبيرا من نسبة الفضلات القابلة للتحلل من سلة المهملات. ونحن نعلم أيضا أنه عندما يتم إرسال المواد الغذائية إلى المكب فإنها تنتج المزيد من الغازات المسببة للاحتباس الحراري إثر تحللها.

· شراء المواد الغذائية وخاصة الفواكه والخضروات بكميات صغيرة حسب الحاجة.
· الحرص على الاستخدام الأمثل للمواد الغذائية وتناول الطعام اللازم وحتى بقايا الوجبات
· لا تشعر بالخجل من أخذ/تعبئة بقايا الوجبات في الحفلات فإنه لا يؤثر على ثقتك بنفسك وسمعتك.
· قم يوميا بجرد المواد الغذائية الخاصة بك في الثلاجة وفي سلة الفاكهة بحثا عن العناصر التي قد تتعفن أو تنتهي صلاحيتها . استفد منها أو تبرع بها قبل أن تصبح نفايات.
Water scarcity has emerged as one of the most pressing challenges facing the Mediterranean basin, a region characterized by sharp climatic gradients, demographic pressures, and structural inequalities in resource distribution. Agriculture alone accounts for between 64% and 79% of freshwater withdrawals in many Mediterranean countries, particularly in the southern and eastern shores, where irrigation is essential for food security and rural livelihoods [1]. Climate change is intensifying these pressures through increased frequency of droughts, rising temperatures, and declining precipitation, thereby exacerbating groundwater depletion and salinization [2].
In this context, decentralized brackish water desalination is gaining recognition as a promising pathway to enhance water availability while supporting climate-resilient and resource-efficient agricultural systems. However, the success of such approaches depends not only on technological innovation but also on the capacity to bridge scientific, economic, and institutional gaps between the northern and southern shores of the Mediterranean.
Brackish water desalination offers a strategic alternative to conventional freshwater resources by tapping into underutilized saline aquifers. Compared to seawater desalination, brackish water treatment generally requires lower energy input and operational costs due to its lower salinity levels, making it particularly suitable for decentralized applications in rural and peri-urban areas [3].
Recent advances in membrane technologies, including low-pressure reverse osmosis, nanofiltration, and hybrid systems, have significantly improved efficiency and reduced energy consumption [4]. Studies published in scientific journals have demonstrated that energy requirements for brackish water desalination can be as low as 0.5–2.5 kWh/m³, compared to 3–4 kWh/m³ for seawater desalination, depending on feedwater characteristics and system design [5]. These improvements create new opportunities for integrating desalination into agricultural practices, particularly when combined with renewable energy sources such as solar photovoltaics.
The integration of renewable energy with desalination technologies is a critical factor in reducing the carbon footprint of irrigation systems and aligning with global climate targets. The Mediterranean region, especially its southern part, has significant solar energy potential, which can be harnessed to power decentralized desalination units [6]. Hybrid systems combining solar energy with battery storage or grid backup have shown promising results in ensuring continuous operation and adapting to seasonal variations in water demand [7]. According to recent technical reports by international agencies, renewable-powered desalination can reduce greenhouse gas emissions by up to 70% compared to fossil-fuel-based systems [8]. This aligns with broader policy frameworks such as the European Green Deal and the Sustainable Development Goals, particularly SDG 6, SDG 7, and SDG 13.
Despite these technological advancements, several barriers continue to hinder the widespread adoption of decentralized desalination systems in Mediterranean agriculture. High initial capital expenditures, limited access to financing, and lack of technical capacity among farmers remain significant challenges [9]. Moreover, the management of brine, a concentrated by-product of desalination, poses environmental risks if not properly handled. Recent research emphasizes the need for circular approaches to brine management, including the recovery of valuable minerals and nutrients, as well as the development of zero-liquid discharge systems [10]. These approaches not only mitigate environmental impacts but also enhance the economic viability of desalination projects.
The socio-economic dimension of water management is particularly critical in the Mediterranean context, where disparities between northern and southern countries are pronounced. Northern Mediterranean countries generally benefit from stronger institutional frameworks, higher levels of technological development, and better access to financial resources. In contrast, southern and eastern countries often face constraints related to governance, infrastructure, and investment capacity [11]. Bridging these gaps requires a comprehensive and inclusive approach that fosters collaboration, knowledge transfer, and co-development of solutions tailored to local conditions.
One of the most effective mechanisms for achieving this is the implementation of multi-actor approaches that actively involve farmers, researchers, technology providers, policymakers, and financial institutions. Living Labs, as highlighted in recent European research initiatives, provide a dynamic platform for co-creation, testing, and validation of innovative solutions in real-world settings [12]. These participatory frameworks ensure that technologies are not only technically sound but also socially acceptable and economically viable. Evidence from pilot projects across the Mediterranean indicates that stakeholder engagement significantly enhances adoption rates and long-term sustainability of water management solutions [13].
Digital technologies are also playing an increasingly important role in optimizing desalination and irrigation systems. The use of Internet of Things (IoT) sensors, artificial intelligence, and digital twins enables real-time monitoring and predictive management of water and energy flows [14]. For instance, AI-driven optimization algorithms can adjust desalination parameters based on feedwater quality and energy availability, thereby improving efficiency and reducing operational costs. Recent studies have shown that digitalization can lead to energy savings of up to 20% and water use efficiency improvements of 15–25% in agricultural systems [15]. These innovations are particularly relevant in decentralized contexts, where resource constraints necessitate smart and adaptive management strategies.
The concept of the water-energy-food-ecosystem (WEFE) nexus provides a comprehensive framework for understanding the interdependencies between different resource systems and for designing integrated solutions. In the Mediterranean region, where water scarcity directly impacts agricultural productivity and energy use, adopting a nexus approach is essential for achieving sustainability [16]. Decentralized desalination systems powered by renewable energy and coupled with efficient irrigation techniques such as drip irrigation can significantly enhance water productivity while minimizing environmental impacts. Moreover, the recovery of nutrients from brine streams can contribute to soil fertility and reduce reliance on chemical fertilizers, thereby supporting circular economy principles [17].
Bridging the gaps between the two shores of the Mediterranean is not only a matter of technology transfer but also of building mutual trust, shared governance structures, and aligned policy frameworks. Collaborative research and innovation programs, such as those funded under regional partnerships, play a crucial role in facilitating cross-border cooperation. These initiatives enable the exchange of best practices, harmonization of standards, and development of joint strategies for addressing common challenges [18]. For example, joint pilot projects involving partners from both northern and southern countries have demonstrated the feasibility of scaling up decentralized desalination solutions while adapting them to diverse agro-ecological conditions [19].
Financial mechanisms are another key element in bridging these gaps. Innovative financing models, including public-private partnerships, blended finance, and microcredit schemes, can help overcome investment barriers and support the deployment of decentralized systems at scale [20]. In particular, engaging local small and medium-sized enterprises (SMEs) in the design, manufacturing, and maintenance of desalination units can stimulate economic development and create job opportunities in rural areas. Evidence from recent case studies suggests that localized value chains significantly enhance the resilience and sustainability of water infrastructure projects [21].
Policy coherence and regulatory support are equally important in enabling the adoption of non-conventional water resources. Clear guidelines on water quality standards, environmental protection, and resource allocation are necessary to ensure the safe and efficient use of desalinated water in agriculture. Furthermore, integrating desalination into national water management strategies and agricultural policies can provide a strong foundation for scaling up innovative solutions [22]. Cross-border policy dialogue and cooperation can also facilitate the alignment of regulatory frameworks and promote the adoption of best practices across the region.
Bottom Line
The success of decentralized brackish water desalination in the Mediterranean depends on the ability to create synergies between technological innovation, socio-economic development, and environmental sustainability. Bridging the gaps between the northern and southern shores is a critical step in this process, as it enables the sharing of knowledge, resources, and experiences that can drive collective progress. By fostering collaboration, promoting inclusive governance, and investing in capacity building, the Mediterranean region can transform water scarcity from a constraint into an opportunity for sustainable development.
Decentralized brackish water desalination represents a transformative solution for addressing water scarcity and enhancing agricultural resilience in the Mediterranean. Its successful implementation requires not only technological advancements but also a holistic approach that integrates renewable energy, digital innovation, circular economy principles, and stakeholder engagement. Bridging the gaps between the two shores of the Mediterranean is essential for unlocking the full potential of these solutions and for ensuring equitable and sustainable development across the region. Through coordinated efforts and shared commitment, the Mediterranean can serve as a model for climate-resilient water management and sustainable agriculture in water-scarce regions worldwide.

Birds are not decorative extras in the urban frame. They are part of the living mechanism that keeps cities functioning — regulating insects, spreading seeds, supporting pollination, and holding together the fragile web of biodiversity that still survives between roads, towers, and heat‑soaked concrete.
Today, as extreme heat becomes a defining reality for cities around the world, this balance is under growing threat.
Rising temperatures and prolonged heatwaves are making urban environments harsher not only for people, but for wildlife struggling to survive in spaces built almost entirely for human comfort. When birds begin to disappear, the whole urban ecosystem starts to fail. Insects multiply unchecked. Biodiversity weakens. Cities become less stable, less resilient, less alive.
It doesn’t promise a distant technological breakthrough. It reveals a solution already flowing through our cities every day — unnoticed, unused, and wasted.
Air conditioners produce condensed water as they cool the air. In most buildings, this clean water simply drips onto pavement and disappears. Drops of Life captures that condensation and redirects it into small drinking points for birds and other urban animals.
A tiny intervention. A massive meaning.
Because this is not just about hydration.
It is about restoring ecological balance where people actually live.
It is about rethinking waste as care.
It is about turning everyday urban infrastructure into an act of shared responsibility.
Most importantly, Drops of Life is not an idea meant to live on a website or inside environmental reports. It is designed to be repeated, copied, and adopted anywhere.
Residents, cafés, offices, schools, property managers, architects, maintenance teams, developers, and city communities: this is your cue. If your building has air conditioners, it already has untapped potential. If your city faces heat and water stress, it already has a reason to act.
Ask how condensation can be collected. Suggest simple dispensers.
Make small water points part of everyday urban life.
That is how real environmental change spreads — not only through awareness, but through simple actions that anyone can repeat. The 3D‑printable model of the water dispenser is openly available at https://dropsoflife.city. Install it. Share it. Improve it.
Drops of Life turns an overlooked urban by‑product into a shared environmental gesture.
A drop that once vanished into concrete can now help birds survive, support biodiversity, and maintain the fragile rhythm between species that keeps cities livable.
Patagonia, an American company, has launched a program called “Worn Wear” to promote its sustainable approach. The initiative encourages customers to repair or reuse their clothing instead of buying new pieces, by providing spare parts for clothes that need repair. Additionally, the company offers a special program for customers through its website, where they can send in their used Patagonia clothing and exchange it for points that can be used to purchase new items. The company also provides important tips for caring for and repairing clothes, as well as offering some used products for sale.
Of course, there are several companies from various countries that follow the sustainable and recycling approach, aiming to reduce the use of resources and keep them in the manufacturing and usage cycle.
So what is the purpose of all this? It is the circular economy, which I tend to call “circular improvement”. This is different from the linear economy, which relies on the usual process from resource extraction to usage, and then disposal of products, which turn into waste and pollution. In the circular economy, the product cycle is extended, while reducing waste and emissions in the product or service journey. This is based on the three principles of using, reusing, and recycling.
With the increasing environmental awareness on one hand, and the negative consequences of the linear economy on the other, it has become necessary to stop the continuous production of waste and its catastrophic effects on the environmental balance, which directly or indirectly affects humans.
So how can companies enhance their presence as effective brands through the circular economy? And can this approach serve them in terms of presence, profitability, and innovation compared to companies that use the linear economy?
In this article, we try to shed light on the importance of the circular economy in shaping the identities of companies in a competitive market. While the circular economy may not be a prominent feature for many sectors, it has proven to be a crucial approach in achieving sustainability and mitigating environmental impacts.
Companies can benefit from the circular economy by:
Reducing costs by adopting more efficient production processes and reducing waste.
The potential to save on raw material costs and disposal, which leads to increased profitability.
Opportunities to increase revenue by designing products that can be reused, repaired, or recycled. These companies can also provide new sources of income by selling refurbished or recycled products.
This is what Patagonia did, as we mentioned earlier, and its practice contributed to reducing costs, reducing waste, and increasing its profitability at the same time.
Creating a unique positioning for the brand without competitors, making the distinction in this area prominent and ahead of others, especially for companies that rely heavily on the linear economy. The transition to the circular economy is an intelligent repositioning for the company, taking a new line that advances over the rest of the competitors.
Building customer loyalty through these environmental practices, which make their impact on the target audience, especially those who are concerned about the environment and are aware of the products they buy. This interest can be reflected in several environmental and social images to form sustainable corporate social responsibility (CSR).
A space for innovation and collaboration by continuously communicating with suppliers, customers, and all parties involved in the product or service cycle. Companies can develop circular models in manufacturing, transportation, and delivery.
One of the notable models, for example, is Philips, where it developed lighting service models, where customers pay for using lighting instead of buying products directly! This trend will reduce waste and provide new revenue opportunities for the company.
Of course, considering understanding the purchasing behavior of the target audience and the importance of aligning the company’s goal with the possibility of changing consumer behavior through possible and practical human engineering.
Challenges facing the circular economy practice
If we look at the matter, although it seems beautiful and encouraging, and although it is possible for companies that want to make their own presence with the sustainability of their products and revenues, there are a number of challenges as there are opportunities, including:
The absence of qualified infrastructure for the circular economy. Therefore, everything we have is based on the linear economy. Hence, the matter needs to work in stages to smartly transition from the linear economy to the circular economy.
Among the possible measures are the implementation of extended responsibility programs for the product, support for the development of supply chains, and the study of time, distance, and the mechanism contributing to the carbon or water footprint of the product or service. Each product consumes a certain amount of energy, which results in carbon emissions, and this is the “carbon footprint,” as well as the amount of water used to provide a product or service, which is the “water footprint.”
Several companies are working to reduce water use during their product manufacturing, including Levi’s, Adidas, H&M, Stella McCartney, and Eileen Fisher.
The need to provide policies and legislation, by directing towards the circular economy gradually, through legislation that encourages reuse, recycling, and waste reduction. The direction towards supporting companies, institutions, and entities that partially adopt the circular economy. This will encourage others to follow suit, and there will be models that can be relied upon even if only partially. This is the starting point for expansion and benefiting from the best practices.
Working on creating public awareness, through continued smart and effective communication with the public through various digital and physical contact points, and demonstrating the mutual added value from the manufacturer of the product or service provider or even the consumer himself, in case of adopting the circular economy in the selection of products and services. It may be difficult for industries with complex supply chains, but there are still many areas where several industries can take their first steps in this direction.
Awareness is through choosing environmentally friendly products and services, promoting a culture of recycling and reuse, and educating individuals on the importance of reducing waste and carbon emissions.
A roadmap for business sustainability can be achieved by incorporating sustainability into various elements of the company’s core identity. For companies focusing on sustainability, collecting feedback throughout the product journey not only encourages innovation but also enhances the overall customer experience by identifying opportunities to implement sustainable changes. Effective real-time feedback systems can help businesses quickly understand and address consumer expectations as seen in modern customer experience platforms. These elements include the purpose, vision, mission, values, positioning, promise, and products/services. They can be abbreviated as 4P2VM, which stands for Purpose, Vision, Mission, Values, Positioning, Promise, and Products.
However, this cannot be accomplished in one fell swoop. It is part of a sustainability strategy that must be embraced by the company or organization. The low number of players in this economy is an opportunity to enter early and gain both material and spiritual benefits, as well as create change. There are challenges, but it is worth working on, and the following steps can help achieve it:
Study the product and service cycle, and examine the possibility of reducing waste from the first birth of the product until its end of life.
Identify areas where the product can move to be closer to the circular economy, such as the type of packaging used with the product, using recyclable or environmentally friendly materials.
Connect that area to one of the aforementioned strategic points, such as the purpose, vision, mission, etc., to make it part of the company’s policy rather than a luxury.
Examine the best practices and include them in the “optimized” product cycle, by studying the experiences of companies from different countries, and looking at the latest technologies and practices in this field.
Start with the initial model of the product or service and calculate the cost, while educating the target audience to be a parallel path, one in the product journey and the other in the customer experience.
Collect feedback from the product manufacturing cycle and from the customer experience and evaluate it.
Make recommendations for continuous improvement.
Expand the experience vertically in terms of supply chains and raw materials, and in terms of product logistics and quantity, while the focus remains on the customer experience and the impact on the environment.
Between environmental balance and innovation
The shift to a circular economy, as a qualitative leap for the economy, naturally presents challenges in transitioning from a linear economy inherited from the first industrial revolution to the present. However, it would be our best option if we want to maintain a healthy and civilized life simultaneously. This balance cannot be achieved with a linear and environmentally polluted economy, leaving heavy consequences of emissions. Rather, it can be achieved through a well-thought-out adoption of what we produce and what is wasted, and the journey between them.
The goal is to increase the lifespan of the product and reduce waste, thus improving the quality of life by providing job opportunities, promoting innovation and expanding the scope of use, and obtaining a better environment, resulting in fewer diseases and better restoration of the earth’s natural cycle.
Identity presence can be created by touching on these possible areas in the circular economy, if included in the strategies of governments and companies in a coordinated manner.
The distinctive presence will be through understanding the circular economy scenario and linking it to the organization’s strategy, with smart employment of available tools to enhance it, including “artificial intelligence,” which can play a role in planning, financial analysis, risk management, understanding the behavior engineering of the target audience, and all this through data analysis, predicting demand and identifying future opportunities.
Artificial intelligence can also analyze data related to product and service usage and design models to develop more efficient and sustainable methods of production and consumption.
Local Reading and the Reality of the Circular Economy
In Bahrain, we produce about 1.2 million tons of solid waste annually, at a daily rate of more than 4,500 tons. This provides many opportunities not only to work on recycling waste at the end of the linear economy but also to work on the beginning, during, and after the product’s birth, and in this way, the process of transforming the linear economy with time into a circular economy can be accomplished.
It seems that there is an ambitious vision, given that the Bahraini government has launched a waste management strategy for the period 2020-2035. The goal is to reduce the amount of waste that is sent to landfills to 60%. If we know that the landfill in Askar is expected to reach its maximum capacity in the coming years, this becomes crucial.
Based on the Economic Recovery Plan in Bahrain, the Kingdom plans to target investments of up to $30 billion in strategic projects, creating new investment opportunities in infrastructure and priority sectors across the Kingdom, including renewable energy sectors such as blue and green hydrogen.
Knowing the quantity and quality of waste and using data analysis, it is possible to determine the percentage of waste from residential, commercial, and industrial use. By providing this data to interested companies, universities, research centers, and institutions in and outside Bahrain, it is possible to work on reverse engineering and providing practical solutions to reduce the amount of waste and focus on transitioning from a linear to a circular economy.
All of this comes within the context of the clear vision of Bahrain’s 2030 economic vision, which talked about the importance of the need to change the current economic model according to sustainability, competitiveness, and justice. As stated in the vision, “Bahrain finds economic model that contributes to achieving sustainable development, enhancing competitiveness, and ensuring social justice.”
To achieve these goals, Bahrain has launched various initiatives and strategies, such as the Waste Management Strategy and the Vision 2030, which aim to create a more sustainable and circular economy. This shift towards a circular economy not only helps to reduce waste and environmental degradation but also creates new opportunities for innovation, job creation, and economic growth.
In conclusion, the issue of solid waste management in Bahrain presents both a challenge and an opportunity to transition towards a circular economy. By leveraging data analysis and engineering, and by implementing various initiatives and strategies, Bahrain can reduce its waste output, create new investment opportunities, and contribute to a more sustainable future.
“Kaizen Day-to-Day”!
When we aim for continuous small changes, as the Japanese call it “Kaizen”, some products can contribute to providing a daily experience for the audience and practically enhance their awareness. Among the displayed products is this device that converts food waste into organic fertilizer that can be utilized! Check out www.Lomi.com.
There is also a Saudi product that provides a smart farm at home, which enables self-sufficiency for some vegetables, and it was discussed in the “Future of Food” episode on the program “Seen” by Ahmed Al-Shugairi. Check out https://www.youtube.com/watch?v=9KC4XKEn10o.
These are images of converting the consumer into a “Prosumer”, i.e., a consumer and producer at the same time. This is a call for action in two directions: first, towards innovation to reduce the amount of waste we dispose of, whether it is food or other products. Second, through social engineering, which can be primarily done by governments, by legislations, laws, and incentives. The less you waste of what you consume, the more you can turn that into appreciation points that individuals can benefit from in different areas of life for products and services that interest them.
If we talk about a slightly larger circle in the industry sector, there are advanced technologies that can save a lot of waste, in addition to energy, by providing innovative and practical solutions. These technologies can balance between the environment, productivity, and quality. One of them is the Magic Fiber product from MTECHX, which is a tested Japanese innovation. It is a cotton piece treated with nano-technology and has unique advantages, such as its absorbency, which helps in treating oil leaks in water, as well as practical applications in factories.
Such technologies can be leveraged and employed to enhance sustainability on the one hand, and productivity and quality on the other hand. All of this can be achieved through the gateway of choosing sustainability as part of the government or company’s identity strategy.
Cycling in a circular economy!
What we need most is to pause for a moment, reflect, read the numbers on pollution, carbon emissions, and waste, and reverse engineer the compass of the economy to make it more circular rather than linear, even if gradually and in specific sectors at first.
This shift offers many opportunities to realign governments, companies, and institutions, with room for innovation and sustainable development, which would reflect positively on revenues, improvement, and growth.
Both factories and banks can play a crucial role in promoting the circular economy through the umbrella of social responsibility and innovation. This should be included in their sustainability strategy to achieve positive results in the environment, economy, and market.
Universities can also leave their mark in the research and development of this change, with the importance of sustainable partnerships between universities, the public and private sectors, banks, and financing.
The circular economy will not be an option in the near future but rather an essential path that governments, companies, and institutions must take. This is an opportunity for them to work on it, whether for sustainability or to create a unique identity.
Future challenges are not limited to energy consumption but rather in how we recycle it to make it last longer. As it has been said before, “we don’t spin in an empty circle” but rather we can “cycle in a productive circle”.
We all know that whirlpool baths are truly a luxurious addition to any home bathroom. They offer a relaxing and soothing experience – an experience we all need in our ever-hectic and demanding lives. However, we also know that whirlpool baths can be quite energy-intensive and, thus, can significantly impact the environment. But fortunately for you, if you’re concerned about your environmental impact but still want to enjoy your whirlpool bath, there are several ways to use it more sustainably and in a more eco-friendly manner. So how can you use your whirlpool bath in a more sustainable way? Let’s learn more about it, shall we?
1. Choose a model that’s energy-efficient
The good news is that whirlpool baths are now more energy-efficient. For instance, you can look for models with a high Energy Factor or EF rating or are ‘Energy Star’ -certified. An Energy Star-certified whirlpool bath can save up to 60% in energy expenses compared to a standard model. Meanwhile, the EF or Energy Factor rating indicates the model’s energy efficiency, with higher ratings indicating greater efficiency.
2. Use eco-friendly cleaning products
When cleaning your whirlpool bath, choose eco-friendly cleaning products. Harsh and strong chemicals can damage the bath’s surface – and even worse, harm the environment. You can instead opt for natural cleaning solutions such as lemon juice, vinegar, or baking soda. These natural cleaners are not only effective – they are also safe and environmentally friendly.
3. Fill the bath with cold water
In order to save energy, fill the bath with cold water as opposed to hot water. With this, you can reduce the energy required to heat the water, saving you money and reducing your environmental impact.
4. Limit the amount of water you use
To reduce water usage, only fill the tub with the amount of water you will need. In other words, avoid overfilling the bath, as this wastes water and can put additional strain on the motor of the whirlpool. If you want, you can use a bucket to measure the amount of water you require before turning on the jets.
5. Use the timer function
Most whirlpool baths today come with a timer function that allows you to set the amount of time the jets will run. You can use this function to limit the time the jets are running. Keep in mind that the longer the jets run, the more energy they consume.
6. Opt for a water-saving showerhead
If your whirlpool bath comes with a showerhead, consider replacing it with a water-saving showerhead. This can help you reduce the water used during your bath, saving you money and decreasing your environmental impact.
7. Don’t forget to maintain your whirlpool bath
Regular upkeep and maintenance are crucial to keeping your whirlpool bath operating efficiently. Follow the manufacturer’s instructions for cleaning and maintenance, and have the unit serviced regularly by a professional. When you have a unit that is well-maintained and cleaned regularly, your whirlpool bath will use less energy and last for a longer time, reducing the need for parts replacements.
Electric vehicle (EV) adoption has gained momentum over the last decade, and it’s not going to slow down. More than 20% of new cars sold worldwide in 2025 were electric. Nothing strange, though, while these are already an integral part of logistics operations, corporate fleets, and employee mobility programs. As electric vehicle adoption spreads, a new question arises: how to manage EV charging costs effectively?
Without proper control, charging infrastructure may quickly increase operational expenses and even strain energy resources. Smart EV charging management helps optimize charging workflows, reduce expenses, and enhance operational performance. In this post, you’ll find out what smart EV charging is, how it works, and how businesses can use it to lower operational costs in a scalable and predictable way.
What is Smart EV Charging
Smart EV charging refers to an intelligent approach to managing electric vehicle charging through software, connected hardware, and data analytics.
At its core, it functions as an EV software management system that gives businesses control over how charging infrastructure interacts with vehicles, energy prices, and grid constraints. It works like this: as soon as a vehicle is plugged in, an EV charger sends data to the charging operator seamlessly via the cloud. It can include information about charging speed and time, current energy usage, and grid capacity. As a result, businesses have a tool for monitoring energy usage, applying charging rules, and adjusting power distribution in real time.
Key Pros for Businesses to Use Smart EV Charging
Smart charging can be incredibly beneficial for EV drivers: it enables quick access to a safe charger and helps reduce costs and protect the environment. But what about businesses? The truth is that an intelligent approach to smart electric vehicle charging is a genuinely future-proof solution for businesses, and here is why:
Reduced energy costs due to off-peak charging
Operational transparency due to real-time monitoring and reporting
Scalability for expanding EV fleets and locations
Remote monitoring of EV charging events
Improved fleet availability through priority-based charging
While all these advantages are appealing, the major impact comes from how smart EV charging management can reduce operational costs in practice. And here are some businesses that already feel the benefits of incorporating EV charging today. See these pros below:
Ways to Lower Operational Costs
By following a few practical principles of smart EV charging, businesses can build an efficient charging management workflow. Let’s take a closer look at the most effective cost-reduction strategies.
Manage Charging to Avoid Peak Pricing
Electricity costs fluctuate throughout the entire day. Charging EVs during peak hours results in sky-high energy bills, especially for businesses operating multiple chargers. A recent analysis of EV charging costs in Europe found that charging at peak times can cost 30% or more than charging during off-peak or night-time rates due to dynamic/grid pricing models.
Smart EV charging systems automatically shift charging to off-peak hours when electricity is cheaper. The system schedules vehicles that do not need immediate charging later, without affecting availability.
Optimize Power Distribution
Installing additional chargers often requires expensive grid upgrades. Unmanaged charging can overload electrical systems and trigger severe outages. In contrast, smart load balancing distributes available power across all active chargers. Therefore, instead of charging all vehicles at full capacity, the system adjusts charging speeds based on demand and grid limits.
Beyond software-based load balancing, validating site capacity requires instrumentation. By monitoring phase currents, voltage sag/swell, harmonics, and THD at panels and feeders, facility teams can quantify real demand, identify power-quality issues that degrade charger efficiency, and set safe limits. Using power analysis for electrical systems enables high-precision measurements, transient capture, and long-term logging, supporting demand-charge mitigation, predictive maintenance, and compliance with IEC/IEEE power quality standards.
Enable Smart Energy Integration
One of the benefits of using intelligent EV charging is that it can be integrated with renewable energy sources, such as on-site battery storage, wind turbines, or solar panels. Charging sessions can be aligned with periods of when renewable energy is available. For businesses investing in sustainability, this reduces reliance on grid electricity and stabilises long-term energy costs.
Maintain Charging Stations Regularly
When it comes to EV charging management, it is crucial to regularly maintain charging stations. The reason is simple: replacements and repairs can be quite expensive. Basic maintenance for Level 1 and Level 2 chargers averages around $400 per station per year, with higher costs for more complex or commercial-grade units like DC fast chargers.
Scheduling checkups ensures the system’s effectiveness, and a rapid response to any disruption can quickly turn into a massive problem. Besides, real-time monitoring is handy for managing a few EV charging stations and conducting diagnostics remotely.
Centralize Management across Locations
Managing EV charging manually across multiple sites is resource-intensive. Different tariffs, usage patterns, and local constraints add a cherry on top. Smart charging platforms provide a single dashboard for all locations. Operation teams can monitor usage, set policies, and analyse costs without being physically on site.
Strategic Investment Into the Future
Smart EV charging management is not just a technical upgrade. It is a system that aligns energy usage with business goals. As EV adoption increases, unmanaged charging becomes a growing operational risk.
Businesses that implement smart charging from the very beginning gain control over how, when, and at what cost electricity is consumed. This enables predictable operating costs, greater scalability, and stronger energy resilience against energy price volatility or grid disruptions.
Rather than reacting to rising demand, organisations can proactively optimize energy consumptions in line with capacity and sustainability goals.
Turn charging strategy into competitive advantage. Download our white paper on global EV regulations to learn how they are redefining uptime, interoperability, and grid integration, and what it means for your charging platform.
Moreover, smart charging platforms have been shown to reduce energy expenses by as much as 20–50% by adjusting charging to off-peak periods and controlling consumption.
Ultimately, smart EV charging transforms infrastructure investment into a competitive advantage.
Bottom Line
Smart EV charging management empowers businesses to maintain control over energy costs. By optimizing charging schedules, centralizing control, and balancing power loads, one can achieve visible cost reduction. As energy prices fluctuate and grid demand increases, intelligent charging becomes vital to maintain efficiency and predictability.
Water scarcity has emerged as one of the most critical global challenges of the twenty-first century, particularly in arid and semi-arid regions where natural water availability is inherently limited and increasingly threatened by climate change. In such contexts, relying on a single water source is no longer sustainable. Scientific consensus increasingly supports the idea that no single solution can solve water scarcity; instead, diversification of water supply sources represents a robust and adaptive risk management strategy. This approach is particularly relevant for countries like Algeria, where water stress is structural, yet where significant investments have been made to mobilize a diversified portfolio of water resources including dams, groundwater, desalination, and wastewater reuse.
Water scarcity in Algeria is characterized by both quantitative and qualitative dimensions. The country experiences highly uneven rainfall distribution, with most precipitation occurring in the northern coastal regions, while vast inland and southern areas remain arid. Furthermore, interannual variability in rainfall has increased due to climate change, leading to recurrent droughts and reduced reservoir inflows. In this context, dependence on a single water source such as surface water would expose the system to severe supply shocks. Diversification, therefore, becomes not merely an option but a necessity to ensure water security and resilience.
Surface water mobilized through dams has historically been the backbone of Algeria’s water supply system. With several of dams constructed across the country, these infrastructures play a crucial role in storing seasonal rainfall and regulating water availability for domestic, agricultural, and industrial uses. However, dam-based systems are inherently vulnerable to climatic variability, sedimentation, and evaporation losses. During prolonged droughts, reservoir levels can decline significantly, reducing their reliability as a sole source of water. This limitation underscores the importance of integrating surface water with other sources within a diversified framework.
Groundwater resources constitute another major component of Algeria’s water supply. In many regions, particularly in agriculture, groundwater serves as a primary source of irrigation water. However, excessive reliance on groundwater has led to overexploitation, declining water tables, and salinization. In northern aquifers, recharge rates are relatively higher but still insufficient to meet growing demand sustainably. In contrast, southern aquifers, such as those in the Sahara, are largely fossil and non-renewable. This makes groundwater a strategic but limited resource that must be carefully managed within an integrated system. Its role in a diversified portfolio is to provide flexibility and buffering capacity during periods of surface water scarcity, rather than serving as a standalone solution.
The expansion of seawater desalination represents one of the most significant transformations in Algeria’s water management strategy over the past two decades. Leveraging its extensive Mediterranean coastline, Algeria has invested heavily in desalination infrastructure to produce potable water independent of rainfall variability. Desalination has become a cornerstone of urban water supply, particularly in coastal cities. Its main advantage lies in its reliability, as it is largely unaffected by climatic fluctuations. However, desalination is energy-intensive and associated with environmental challenges such as brine discharge.
Recent research emphasizes the importance of coupling desalination with renewable energy sources to enhance sustainability and reduce operational costs. For instance, studies have demonstrated the feasibility of integrating photovoltaic systems with reverse osmosis desalination units in Algeria, highlighting the country’s potential to harness solar energy for water production [1].
Wastewater treatment and reuse add another critical dimension to the diversification strategy. Rather than viewing wastewater as a liability, modern water management frameworks recognize it as a valuable resource. In Algeria, significant investments have been made in wastewater treatment plants, enabling the production of treated effluent that can be reused in agriculture, industry, and landscaping. This approach reduces pressure on freshwater resources and contributes to a circular economy model. Water reuse is particularly advantageous because it provides a stable and predictable supply that is less affected by climatic variability. Moreover, integrating reuse into the water system enhances overall efficiency by maximizing the utility of existing water resources. The combined use of desalination and wastewater reuse has been identified as a key opportunity within the water–energy–food nexus framework, supporting both water security and agricultural productivity [2].
The concept of diversification in water supply can be understood as analogous to financial portfolio management, where risk is minimized by investing in a variety of assets with different characteristics. In the context of water resources, each source, surface water, groundwater, desalination, and reuse has distinct advantages and limitations in terms of availability, cost, quality, and resilience to external shocks. By combining these sources, Algeria reduces its vulnerability to any single point of failure. For example, during drought periods when dam levels are low, desalination plants can maintain a steady supply of drinking water. Similarly, treated wastewater can be used for irrigation, reducing the demand for freshwater and preserving groundwater reserves.
Beyond technical considerations, the success of a diversified water strategy depends on governance, infrastructure integration, and policy coherence. Algeria has made progress in developing large-scale water transfer systems that connect dams, desalination plants, and urban centers, allowing for more flexible allocation of water resources. Institutional coordination among different sectors; water, energy, agriculture, and environment is essential to optimize resource use and manage trade-offs. The water–energy–food nexus approach provides a useful framework for understanding these interconnections and designing integrated solutions that enhance overall system sustainability. Recent studies in Algeria have demonstrated how desalination and agricultural expansion can be analyzed within this nexus framework to assess impacts on resource use and sustainability [3].
Despite these advances, several challenges remain. The high energy demand of desalination raises concerns about economic and environmental sustainability, particularly in the context of fossil fuel dependence. Integrating renewable energy into desalination processes is therefore a priority. Groundwater overexploitation continues to threaten long-term sustainability, requiring stricter regulation and monitoring. Water quality issues, including pollution from industrial and agricultural activities, further complicate management efforts. Additionally, improving water use efficiency, particularly in agriculture, is essential to reduce overall demand and complement supply-side measures.
Bottom Line
The Algerian experience clearly illustrates that no single solution can address the complex and multifaceted challenge of water scarcity. Diversification of water resources, combining dams, groundwater, desalination, and wastewater reuse provides a resilient and adaptive framework for managing water under conditions of uncertainty. Each component plays a specific role within the system, and their integration enhances overall reliability, efficiency, and sustainability. As climate change continues to exacerbate water scarcity worldwide, the lessons from Algeria underscore the importance of adopting diversified and integrated approaches to water management. Such strategies not only reduce risk but also create opportunities for innovation, resource efficiency, and sustainable development.

Wastewater treatment is evolving from a pollutant removal process to a resource recovery system. In the context of increasing water scarcity and global energy transition, wastewater represents a strategic source of reusable water, nutrients, and energy. This study analyzes the role of wastewater treatment technologies as a driver of energy transition and water security. Based on a critical review of scientific and institutional literature, conventional and advanced treatment systems are compared. Results indicate that anaerobic digestion and nature-based solutions significantly improve energy recovery and reduce carbon emissions. Wastewater treatment plants can thus evolve into energy-positive infrastructures within the water–energy nexus.
Introduction
Water scarcity and energy transition are two of the most pressing global challenges. Wastewater treatment plays a central role in both, as it directly impacts water reuse, environmental protection, and energy consumption.
Despite progress, a significant proportion of global wastewater remains insufficiently treated, leading to environmental degradation and public health risks [1]. Conventional wastewater treatment plants (WWTPs) are energy-intensive systems, primarily due to aeration and sludge management processes [2].
Recent technological advances have introduced the concept of resource-oriented wastewater treatment, where water, energy, and nutrients are recovered [3]. This paradigm shift aligns with the water–energy–resource nexus, positioning wastewater treatment as a key contributor to sustainability.
Methodology
This study is based on a systematic and critical literature review, including:
peer-reviewed scientific articles
international institutional reports
engineering reference books
The evaluation criteria include:
energy consumption
energy recovery potential
greenhouse gas emissions
water reuse potential
technological maturity
Technologies are classified into:
conventional systems
advanced and sustainable systems
Results
Conventional Wastewater Treatment Systems
Conventional systems consist of primary, secondary, and tertiary treatment processes. These systems are effective for pollutant removal but are characterized by:
high energy consumption (especially aeration)
significant sludge production
limited resource recovery
As a result, they are not optimized for energy efficiency or sustainability [2].
Energy Recovery via Anaerobic Digestion
Anaerobic digestion is a key technology enabling energy recovery:
conversion of organic matter into biogas (methane)
reduction of sludge volume
improved energy balance
Studies show that anaerobic processes can significantly reduce net energy consumption and, in some cases, allow energy-neutral or energy-positive operation [6].
Hybrid systems combining anaerobic and aerobic processes or integrating biological and natural systems enhance treatment efficiency and resource recovery [7].
Water Reuse and Resource Recovery
Wastewater reuse contributes to:
reduction of freshwater demand
increased water availability
improved resilience in water-scarce regions
Recovered nutrients (nitrogen and phosphorus) can be reused in agriculture, reinforcing circular economy principles [8].
Discussion
The results confirm a major transition in wastewater treatment philosophy:

Food waste is a huge environmental and socio-economic issue in the State of Qatar. In 2012, a massive 1.4 million metric tonnes of food was consumed and wasted in Qatar. This figure, divided by the then population of 2.05 million, equates to an average of 636 kilograms (kg) of food per person for the year, or 1.74 kg per day. Given the benchmark of two kg per person per day (preferably nutritious fare that does not contain too many kilojoules), that does not sound too excessive. But if you remove the young, elderly, short-term visitors/workers and people who consume less than two kg per day from the equation, it is clear that much more than two kg per adult is either consumed or wasted. This only compounds the country’s rapidly growing and expensive obesity problem.
Added to the wasted food are the litres of bottled water and soft or hot drinks that are consumed every day. The average Qatari resident uses more 500 litres of water per day (drinking, washing and waste), at a rate double that of the average European.
Over and above the 1.4 million tonnes of wasted food, an additional 14 percent – representing nearly 20 million kilograms – is also discarded or destroyed before it even reaches the Qatari end-consumer. This food is either past its sell-by date or spoilt due to problems with the cooling chain. On one hand, this is due to a lack of effective agricultural planning, and decades of environmental degradation (after all, even the local fish industry is but a shadow of its former self).
But on the other hand, Qatar’s growing and increasingly affluent population means that money is no deterrent in terms of the quantity and quality of food demanded. Huge banquets, often with expensive exotic food, are commonplace, and Qatar is the fastest-growing food consumption market among Gulf Cooperation Council (GCC) countries.
Based on UNEP methodology, the per capita food waste generation in Qatar is estimated to be 92.9 kg per person per year which is among the highest worldwide. But while Qatar as a country, and the GCC as a region, are among the biggest culprits, food waste is a global problem. Nearly 30 percent of all food fails to end up in someone’s mouth, and if the total worldwide food loss and waste were a country, it would be the third largest CO2 offender on the planet.
Qatar-based sustainability advocacy group EcoMENA estimates that about half of the waste sitting in Qatar’s landfills is made up of leftover food. The combination of the country’s very high consumption rate and very low recycling rate, mean that mountains upon mountains of food are being dumped. Furthermore, only a minimal portion of this discarded food is being composted, despite the short supply of good soil. EcoMENA’s research shows that up to 25 percent of all food prepared during Ramadan is eventually thrown away – even at a time when the distribution of leftover food to the poor is traditionally at its highest.
