Introduction to Trigeneration

Trigeneration refers to the simultaneous generation of electricity and useful heating and cooling from the combustion of a biomass fuel or a solar heat collector. Conventional coal or nuclear-powered power stations convert only about 33% of their input heat to electricity. The remaining 67% emerges from the turbines as low-grade waste heat with no significant local uses so it is usually rejected to the environment. What is Trigeneration In a trigeneration system, the supply of high-temperature heat first drives a gas or steam turbine powered generator and the resulting low-temperature waste heat is then used for water or space heating. Such systems can attain higher … Continue reading

تحلل نفايات الإطارات

يتم تجاهل عشرات الملايين من الإطارات في منطقة الشرق الأوسط كل عام . إن التخلص من نفايات الإطارات  مهمة صعبة لأن الإطارات لها عمر طويل وغير القابلة للتحلل . الطريقة التقليدية في إدارة نفايات الإطارات هي تخزينها أو إغراقها أو طمرها  غير القانوني، وكلها حلول قصيرة الأجل .الإطارات المخزونة توفر  أرضا خصبة مثالية لتكاثر البعوض، والحشرات والثعابين . بعض الحرائق المفاجئة او العرضية في مكبات الإطارات في إثارة إصدار الغازات السامة منها لأشهر . على سبيل المثال، شب حريق هائل  في الجهراء موقع تفريغ في الكويت في ابريل 2012 حيث تم تخزين أكثر من 5 ملايين من نفايات الإطارات . … Continue reading

Food Waste and the Spirit of Ramadan

In recent years, enormous generation of food waste during the holy month of Ramadan has been a matter of big debate in Muslim countries and elsewhere. As per conservative estimates, around one-fifth of the food purchased or prepared during Ramadan finds its way to garbage bins or landfills. This translates into thousands of tons of precious food which could have been used for feeding tens of millions of hungry people in impoverished countries of Asia, Africa and elsewhere. The staggering amount of food waste generation during Ramadan urgently demands a strong strategy for its minimization, sustainable utilization and eco-friendly disposal.  Gravity of … Continue reading

Solar Energy in Saudi Arabia: Perspectives

Saudi Arabia, the epicenter of global oil industry, has been showing keen interest in solar energy in recent years. Saudi Arabia has one of the world’s highest solar irradiation in the world, estimated at approximately 2,200 thermal kWh of solar radiation per m2. The country is strategically located near the Sun Belt, in addition to plentiful availability of empty stretches of desert that may accommodate infrastructure for solar power projects. Vast deposits of sand can be used in the manufacture of silicon PV cells which makes Saudi Arabia an attractive location for solar industry. “The resource is stunning; land is … Continue reading

Solid Waste Management in Bahrain

The Kingdom of Bahrain is an archipelago of around 33 islands, the largest being the Bahrain Island. The population of Bahrain is around 1.2 million marked by population density of 900 persons per km2, which is the highest in the entire GCC region. The country has the distinction of being one of the highest per capita waste generators worldwide which is estimated at 1.67 – 1.80 kg per person per day. Infact, Bahrain produces largest amount of waste per person among GCC countries despite being the smallest nation in the region. Rising population, high waste generation growth rate, limited land … 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

African Development Bank and Renewable Energy

Africa has huge renewable energy potential with some of the world’s largest concentration of alternative energy resources in the form of solar, wind, hydro, and energy. Overall, 17 countries in sub-Saharan Africa are in the top-33 countries worldwide with combined reserves of solar, wind, hydro, and geothermal energy far exceeding annual consumption. Most of the sub-Saharan countries receive solar radiation in the range of 6-8 kWh/m2/day, which counts among the highest amounts of solar radiation in the world. Until now, only a small fraction of Africa’s vast renewable energy potential has been tapped.  The renewable energy resources have the potential … Continue reading

الطاقه المتجددة بالمغرب العربي

المغرب، كونها أكبر مستورد للطاقة في شمال أفريقيا، تبذل جهودا مركزة للحد من اعتمادها على الوقود الأحفوري المستورد. وتعتبر الطاقة المتجددة  مصدر موثوق في بلد مثل المغرب العربي التي لديها الاعتماد الكامل تقريبا على شركات الطاقة المستوردة.والمغرب تنفق سنويا  أكثر من 3 مليارات دولار على واردات الوقود والكهرباء في حين انها تشهد نمو الطلب على الطاقة بمعدل 6.5 في المئة سنويا. وفقا لتقرير الوزارة المغربية للطاقة والتعدين، الطاقة الإجمالية المركبة للطاقة المتجددة (باستثناء الطاقة المائية) ما يقرب من 300ميجا وات في عام 2011. وقد حققت الحكومة المغربية بالفعل هدفها المتمثل في توفير حوالي 8٪ من إجمالي الطاقة الأولية من مصادر … Continue reading

CDM Projects in MENA Region

  The MENA region is an attractive CDM destination as it is rich in renewable energy resources and has a robust oil and gas industry. Surprisingly, countries in MENA host very few and declining number of CDM projects with only 23 CDM projects registered till date. The region accounts for only 1.5 percent of global CDM projects and only two percent of emission reduction credits. The two main challenges facing many of these projects are: weak capacity in most MENA countries for identifying, developing and implementing carbon finance projects and securing underlying finance.  The registered CDM projects in MENA countries … Continue reading
