Garbage Woes in Cairo

Cairo, being one of the largest cities in the world, is home to more than 15 million inhabitants. Like other mega-cities, solid waste management is a huge challenge for Cairo municipality and other stakeholders.  The city produces more than 15,000 tons of solid waste every day which is putting tremendous strain on city’s infrastructure. Waste collection services in Cairo are provided by formal as well as informal sectors. While local authorities, such as the Cairo Cleanliness and Beautification Authority (CCBA), form the formal public sector, the informal public sector is comprised of traditional garbage-collectors (the Zabbaleen). Around 60 percent of the … Continue reading

The Menace of Landfills in Kuwait

Kuwait, being one of the richest countries, is among the highest per capita waste generators in the world. Each year more than 2 million tons of solid waste in generated in the tiny Arab nation. High standards of living and rapid economic growth has been a major factor behind very high per capita waste generation of 1.4 to 1.5 kg per day. The prevalent solid waste disposal method in Kuwait is landfill burial. Despite being a small country, Kuwait has astonishingly high number of landfills. There are 18 landfills, of which 14 sites are closed and 4 sites are still … Continue reading

تحسين الوضع الاقتصادي للمجتمعات عن طريق تعزيز مشاريع إعادة التدوير

   تعتبر البلديات و المجالس المحلية المسئول المباشر عن إدارة ملف النفايات الصلبة في المدن حول العالم للحفاظ على المدن نظيفة. ففي الوقت التي تحتل فيه التكنولوجيا المتوفرة (جمع النفايات، النقل، إعادة التدوير، التخزين، المعالجة)، تزداد النداءات الدولية لإعادة النظر إلى مجال إدارة النفايات الصلبة كأداة لحل العديد من المشاكل الاقتصادية، الإجتماعية، و البيئية. و من هذه الأصوات الرئيس الأمريكي السابق "بيل كلينتون" عندما صرح في المؤتمر السنوي لمبادرة كلينتون العالمية عام 2010 " إذا أردتم محاربة التغير المناخي، تحسين الصحة العامة، إيجاد فرص عمل للفقراء و خلق مناخ مناسب للروّاد، فإن أفضل الطرق للوصول لهذا الشيئ هو إغلاق مكبات النفايات" … Continue reading

Solid Waste Management in Iraq

Iraq is one of the most populous Arab countries with population exceeding 32 million. Rapid economic growth, high population growth, increasing individual income and sectarian conflicts have led to worsening solid waste management problem in the country. Iraq is estimated to produce 31,000 tons of solid waste every day with per capita waste generation exceeding 1.4 kg per day. Baghdad alone produces more than 1.5 million tons of solid wastes each year. Rapid increase in waste generation production is putting tremendous strain on Iraqi waste handling infrastructure which have heavily damaged after decades of conflict and mismanagement. In the absence … Continue reading

Solid Waste Management in Qatar

Qatar is counted among the world’s fastest growing economies. Municipal solid waste management is one of the most serious challenges faced by this tiny Gulf nation on account of high population growth rate, urbanization, industrial growth and economic expansion. The country has one of the highest per capita waste generation rates worldwide which is as high as 1.8 kg per day. Qatar produces more than 2.5 million tons of municipal solid waste each year. Solid waste stream is mainly comprised of organic materials (around 60 percent) while the rest of the waste steam is made up of recyclables like glass, … Continue reading

Solid Waste Management in Jordan

Jordan is an emerging and stable economy in the Middle East. The growing industrialization and high population growth rate has led to rapid increase in solid waste generation in the country which has, in turn, put increasing pressure in waste management infrastructure. Around 2 million tons of municipal waste is generated in Jordan each year with most of it diverted to unsanitary landfills and dumpsites. Improper solid waste disposal is leading to public health risks, adverse environmental impacts as well as socio-economic problems.  Solid Waste Generation The predominant fraction in Jordanian MSW is organic matter which makes up as much as … Continue reading

Solid Waste Management in Kuwait

With rapid economic growth, solid waste generation is increasing rapidly in Kuwait. Presently, Kuwait is facing serious challenges in solid waste management sector. which is grossly affecting the environmental, economic and social situation in the country in addition to precipitating climate change. The World Bank noted that Kuwait has a very high per capita waste generation of 1.55 kg per day, much higher than the global per capita average of 0.74 kg per day. The predominant solid waste disposal method in Kuwait is landfill burial which act as dumpsites without considering environmental and safety precautions. The land area of Kuwait is … Continue reading

Thermophilic Composting and its Relevance for MENA

Thermophilic composting of organic waste is getting increasing attention worldwide because of its ability to convert solid wastes into organic fertilizer within a short period of time. The system consists of an enclosed reactor laced with a microbe-enzyme cocktail. The commonly used microorganisms are naturally occurring bacillus sp., pseudomonas sp, bifidobacterium sp., lactobacillus sp., streptomyces sp., corynbacterium sp etc. Enzymes such as proteinase, keratinase, lipase and cellulose are employed to accelerate the aerobic digestion process. Salient Features The most important feature of thermophilic composting process is its operating temperature range of 70 – 80 °C which eliminates all pathogens and harmful … Continue reading

إدارة النفايات الصلبة في قطر

تعتبر إدارة النفايات البلدية الصلبة أحد أخطر و أصعب التحديات التي تواجهها جميع البلدان في الشرق الأوسط. و قد أدت عوامل عديدة في زيادة تراكم هذه النفايات الصلبة على أرجاء المنطقة. و من هذه العوامل على سبيل المثال إرتفاع معدل النمو السكاني، المدنية، الهجرة، النمو السريع في المجال الصناعي والتوسع الاقتصادي أيضآ. فمن المثير للإهتمام، أن معدل النفايات الصلبة التي تنتج من الشخص الواحد في دول مجلس التعاون الخليجي تعد الأعلى نسبة في العالم. و قد أدى هذا الإرتفاع في حجم النفايات الصلبة إلى خلق بيئة غير صحية لسكان منطقة الشرق الأوسط. حيث قدر حجم هذه النفايات ب 150 مليون طن سنويا.   النفايات البلدية الصلبة … Continue reading

A Primer on Landfill Gas Recovery

Landfill gas (or LFG) is generated during the natural process of bacterial decomposition of organic material contained in municipal solid waste landfills or garbage dumps. The waste is covered and compressed mechanically as well as by the weight of the material that is deposited above. This material prevents oxygen from accessing the waste thus producing ideal conditions for anaerobic microorganism to flourish. This gas builds up and is slowly released into the atmosphere if the landfill site has not been engineered to capture the gas. The rate of production is affected by waste composition and landfill geometry, which in turn influence the … Continue reading

Waste Management Outlook for Qatar

Qatar is counted among the world’s fastest growing economies as well as richest countries in the world. The rapid industrialization of the country and high population growth generates a lot of wastes in the form of municipal wastes, construction & demolition debris, industrial wastes etc. Annual solid waste generation in Qatar has crossed 2.5 million tons, which corresponds to daily waste generation of more than 7,000 tons per day. The country has one of the highest per capita waste generation worldwide which ranges from 1.6 to 1.8 kg per day. Solid Waste Management Scenario Solid waste is mainly comprised of organic … Continue reading

MSW Generation in the Middle East

The high rate of population growth, urbanization and economic expansion in the Middle East is not only accelerating consumption rates but also increasing the generation rate of all  sorts of waste. Bahrain, Saudi Arabia, UAE, Qatar and Kuwait rank in the top-ten worldwide in terms of per capita solid waste generation. The gross urban waste generation quantity from Middle East countries has crossed 150 million tons per annum.The world’s dependence on Middle East energy resources has caused the region to have some of the largest carbon footprints per capita worldwide. The region is now gearing up to meet the challenge of … Continue reading
