Waste Management in Gaza Strip

Solid waste management in Gaza Strip is a matter of grave concern. With population of approximately 1.75 million, waste management is one of the most serious challenges confronting the local authorities because of high volumes of solid waste generation and economic blockade by Israel. The daily solid waste generation across Gaza is more than 1300 tons which is characterized by per capita waste generation of 0.35 to 1.0 kg. Scarcity of waste disposal sites coupled with huge increase in waste generation is leading to serious environmental and human health impacts on the population. The severity of the crisis is a … Continue reading

Waste Management Perspectives for Egypt

Egypt occupies 7th position in the list of countries with the most mismanaged plastic waste, according to a recent report published in Science magazine. The report was based on data collected in 2010 and one must wonder whether the results of the report would have been different if the zabbaleen had been allowed to continue their work unhindered. A History of the Zabbaleen The zabbaleen, or garbage collectors, are the descendants of farmers from Upper Egypt who moved to Cairo in the 1940s. Together with another migrant group, they have made a living in Cairo collecting, sorting, salvaging, and recycling … Continue reading

Waste Management in Morocco

Solid waste management is one of the major environmental problems threatening the Mediterranean Kingdom of Morocco. More than 5 million tons of solid waste is generated across the country with annual waste generation growth rate touching 3 percent. The proper disposal of municipal solid waste in Morocco is exemplified by major deficiencies such as lack of proper infrastructure and suitable funding in areas outside of major cities.  According to the World Bank, it was reported that before a recent reform in 2008 “only 70 percent of urban MSW was collected and less than 10 percent of collected waste was being … Continue reading

Waste Management Perspectives for Saudi Arabia

Solid waste management is a big challenge for the government and local authorities in the Kingdom of Saudi Arabia. The country generates more than 15 million tons of municipal waste each year with vast majority diverted to landfills and dumpsites. Recycling, reuse and energy recovery is still at an early stage, although they are getting increased attention. Recycling rate ranges from 10-15%, mainly due to the existence of the informal sector which extracts recyclables from municipal waste stream. Waste management issues in the Kingdom can be resolved by creating a healthy general environment specifically targeting the waste sector which may … Continue reading

إدارة النفايات الصلبة في المملكة العربية السعودية

تشهد المملكة العربية السعودية طفرة صناعية وزيادة في النمو السكاني وزيادة في عدد المدن الجديدة، مما أدى الي زيادة في معدلات التلوث والنفايات. أصبحت إدارة النفايات الصلبة تشكل تحدياً كبيراً يومياً للحكومة. مع تعداد سكاني يقارب الـ 29 مليون نسمة، تنتج السعودية أكثر من 15 مليون طن نفايات صلبة سنوياً. والمعدل التقديري لنصيب الفرد يومياً في انتاج النفايات 1.5 – 1.8 كج. معدل النفايات الصلبة للمدن الثلاث الكبرى – الرياض، جدة، الدمام – تزيد على 6 مليون طن في السنة، مما يعطي تصوراً عن حجم المشكلة التي تواجهها. أكثر من 75% من السكان يسكنون المناطق الحضريه، مما يوجب على الحكومة … Continue reading

Waste Management Perspectives for Bahrain

Fast industrialisation, urbanisation, enhanced consumerism and rise in standards of living is causing generation of large quantities of waste which needs to be stored, transported, treated and disposed. Globally, municipal and urban governments are spending huge financial and human resources on waste management but the service coverage is barely coinciding with the generated waste quantities as overflowing communal containers and waste heaps are amply witnessed in all major urban centres. The worldwide quantities of Municipal Solid Waste (MSW) are rapidly increasing. It is estimated that around 2.5 billion MT of MSW was generated worldwide in 2000, which is expected to … Continue reading

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
