Trash Talk from Gaza

Solid waste management is considered to be one of the most severe environmental and civic problems in the Gaza Strip. Solid waste in the Gaza strip consists mainly of household waste, building debris, agricultural waste, industrial waste (mainly from worksites), medical wastes, and wastes from car workshops. Solid waste in the Gaza Strip is dumped in the same landfill without separation except for medical waste, which is dumped separately in the main Gaza landfill site. The solid waste generation rate varies between 0.35 to 1.0 kg/capita/day. Scale of the Problem Trash generation in the Gaza Strip varies between 830 to 894 tons/day … 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

Solid Waste Management in Tunisia

Solid waste management has emerged as a big challenge for the Mediterranean country of Tunisia. The country, having an estimated population of around 11 million people, produces more than 2.5 million tons of garbage each year. Tunisia is experiencing an average increase in waste volume by 3% with per capita waste generation in urban areas being 0.8 kg per day. Biodegradable organic fraction constitutes around 68% of the MSW stream. MSW collection is covered at 80% in urban areas and 10% in rural areas. The country has 10 controlled landfills with a capacity of 1,788,000 tons per year and four other … 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

What is Waste-to-Energy

Energy is the driving force for development in all countries of the world. The increasing clamor for energy and satisfying it with a combination of conventional and renewable resources is a big challenge. Accompanying energy problems in different parts of the world, another problem that is assuming critical proportions is that of urban waste accumulation. The quantity of waste produced all over the world amounted to more than 12 billion tons in 2006, which increased to 13 billion tons in 2011. The rapid increase in population coupled with changing lifestyle and consumption patterns is expected to result in an exponential … Continue reading

Waste-to-Energy Pathways

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. Thermochemical Conversion The three principal methods of thermochemical conversion are combustion (in excess air), gasification (in reduced air), and pyrolysis (in absence of air). The most … 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

Fuel Pellets from Solid Wastes

MSW is a poor-quality fuel and its pre-processing is necessary to prepare fuel pellets to improve its consistency, storage and handling characteristics, combustion behaviour and calorific value. Technological improvements are taking place in the realms of advanced source separation, resource recovery and production/utilisation of recovered fuel in both existing and new plants for this purpose. There has been an increase in global interest in the preparation of Refuse Derived Fuel (or RDF) containing a blend of pre-processed MSW with coal suitable for combustion in pulverised coal and fluidised bed boilers. Pelletization of Urban Wastes Pelletization of municipal solid waste involves the … Continue reading

Waste-to-Energy in Jordan: Potential and Challenges

Effective sustainable solid waste management is of great importance both for people’s health and for environmental protection. In Jordan, insufficient financial resources, growing population, rapid urbanization, inadequate management and lacking of technical skills represent a serious environmental challenge confronting local government. At the same time, energy remains Jordan’s top challenge for development. The energy needs to be produced in a sustainable way, preferably from renewable sources which have a minimum environmental impact. To face the future problems in waste management, as well as securing the demand of renewable energy, it is necessary to reuse the wasted resources in energy production. … Continue reading

النفايات الصلبة في قطاع غزة

لم تكن التحذيرات التي أطلقها منسق الشئون الإنسانية  بالأمم المتحدة "ماكسويل جيلارد" بالأمر المفاجئ أو الغريب على أكثر من مليون و نصف غزّي يسكنون في تلك البقعة من العالم. هذه التحذيرات بنيت على دراسة تابعة للأمم المتحدة صدرت في شهر أغسطس 2012 و أشارت إلى أن قطاع غزة لن يكون "ملائماً للحياة" بحلول عام 2020. فقطاع غزة يعاني من مشكلات كثيرة منذ أكثر من عقد من الزمان مع بدء الانتفاضة الثانية عام 2001 و ما تلاه من حصار خانق بعد فوز حركة المقاومة الإسلامية حماس في الانتخابات التشريعية عام 2006. في أيامنا هذه و مع وصول أول سفينة فضائية لكوكب … Continue reading

ادارة النفايات في الشرق الاوسط – التحديات الرئيسية

يعد الشرق الأوسط من  اخصب الأماكن في توليد النفايات عالميا, ويعد نمط الحياة المسرف, و التشريعات غير الفعالة, و معيقات توفير البنى التحتية, و السلوكيات العامة غير المبالية, و انقص التوعية البيئية من العوامل الأساسية المؤدية لنمو مشاكل النفايات في الشرق الأوسط. كما يسهم مستوى المعيشة المرتفع  مقرونا بعدم توفر مرافق جمع والتخلص من النفايات في تحويل موضوع "القمامة"  الى "مسؤولية" . العقبات الرئيسية ان الأدراك العام للنفايات يتمحور حول اللامبالاة و عدم الاكتراث, و يتم التعامل مع النفايات  على انها(نفايات) و ليس (موارد). وهناك حاجة ملحة لزيادة الوعي لدى العامة حول القضايا البيئية, وممارسات ادارة النفايات الصلبة و المعيشة … Continue reading

Solid Waste Management in the Middle East – Major Challenges

Middle East is one of the most prolific waste generating regions of the world. Lavish lifestyle, ineffective legislations, infrastructural roadblocks, indifferent public attitude and lack of environmental awareness are the major factors responsible for growing waste management problem in the Middle East. High standards of living are contributing to more generation of waste which when coupled with lack of waste collection and disposal facilities have transformed ‘trash’ into a liability. Major Hurdles The general perception towards waste is that of indifference and apathy. Waste is treated as ‘waste’ rather than as a ‘resource’. There is an urgent need to increase public awareness about … Continue reading
