Fuel Pellets from Solid Wastes

Municipal solid waste is a poor-quality fuel and its pre-processing is necessary to convert it into fuel pellets to improve its consistency, storage properties, handling characteristics, combustion behaviour and calorific value. Technological improvements are taking place in the realms of advanced source separation of MSW, resource recovery and production of MSW fuel pellets in both existing and new plants for this purpose. There has been an increase in global interest in the preparation of MSW fuel pellets or Refuse Derived Fuel (or RDF) so let us take a close look at this interesting alternative fuel. Pelletization of Muncipal Solid Waste … Continue reading

Recycling of PET Plastic Bottles

Like all other modern urban centers, the Middle East also faces challenges in environmental protection due to tremendous tonnage of plastic waste produced in different forms.

The burgeoning population, growing consumption, and an increasing trend towards a “disposable” culture, is causing nightmares to municipal authorities across the region and beyond. Plastic consumption has grown at a tremendous rate over the past two decades as plastics now play an important role in all aspects of modern … Continue reading

Significance of E-Waste Management

E-Waste is the fastest growing waste stream, and its disposal is a major environmental concern in all parts of the world. More than 50 million tons of e-waste is generated every year with major fraction finding its way to landfills and dumpsites. E-waste comprises as much as 8% of the municipal solid waste stream in rich nations, such as those in GCC. Globally only 15 – 20 percent of e-waste is recycled while the rest is dumped into developing countries. However, in the Middle East, merely 5 percent of e-waste is sent to recycling facilities (which are located in Asia, … Continue reading

أسلوب حياة أخضر

Recycling Attitudes in Saudi Arabia: A Survey

The waste management and recycling industry in Saudi Arabia is underestimated source of income. The continued increase in population and industrial development in the Kingdom has increased individual waste generation manifolds in the past few decades. The shortage of recycling industries in Saudi Arabia cost around SR 40 billion. The focus of Saudi recycling industry is plastic, papers and metals. If recycling industry targeted only plastic and paper and metals they can meet the need of the Saudi market efficiently. According to Arab League, recycling industry in Saudi Arabia can save over 500 million SR just from iron, paper and … 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. Solid waste management in the Middle East is bogged down by major challenges like lavish lifestyles, ineffective legislation, infrastructural roadblocks, indifferent public attitude and lack of environmental awareness. 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 … Continue reading

مشكلة رمي النفايات في الأردن

في الماضي القريب، كانت عمان تعتبر واحدة من أنظف المدن في العالم,  حالياً، وكما هو الحال في البلدان الأخرى، يشكل رمي النفايات على الأرض في المناطق العامة مشكلة بيئية متزايدة في الأردن, والتي بدورها تشوه المظهر العام للبلاد كما أن لها آثاراً خطيرة على البيئة والإقتصاد والصحة العامة. “القمامة غير المرئية“ تعتبر ظاهرة الرمي العشوائي للنفايات كارثة وطنية، حيث تنتشر النفايات المختلفة مثل العلب المعدنية والأكياس البلاستيكية وأعقاب السجائر والمحارم وأغلفة الطعام والإطارات القديمة على جوانب الطرق. لتسليط الضوء على المشكلة, قامت كاتبة المقال بدراسة ماسحة في عام 2011، حيث كشفت الدراسة عن المفاهيم الخاطئة لدى العامة لمفهوم “النظافة” في … Continue reading

Reuse and Repurposing of Old Clothes

Tens of millions of tons of old clothes are discarded worldwide each year. In affluent countries, around 5-6% of the municipal solid waste is comprised of used clothes.  Americans discarded 13.1 million tons of textiles in 2010, out of which only 15 percent was recycled, while more than 11 million tons of textiles were dumped in landfills across the country. The situation is no different in the Middle East where huge amount of clothes and other fabrics gets accumulated in our homes each year. When thrown in communal bins, textile wastes are transported to the landfill site, where it is … Continue reading

What is Vermicomposting

Vermicomposting is a type of composting in which certain species of earthworms are used to enhance the process of organic waste conversion and produce a better end-product. It is a mesophilic process utilizing microorganisms and earthworms. Earthworms feeds the organic waste materials and passes it through their digestive system and gives out in a granular form (cocoons) which is known as vermicompost. Simply speaking, vermicompost is earthworm excrement, called castings, which can improve biological, chemical, and physical properties of the soil. The chemical secretions in the earthworm’s digestive tract help break down soil and organic matter, so the castings contain … Continue reading

Solid Waste Management Challenges in GCC

The challenges posed by solid waste to governments and communities are many and varied. In the GCC region, where most countries have considerably high per capita waste generation values, the scale of the waste management challenge faced by civic authorities is even bigger. Fast-paced industrial growth, recent construction boom, increasing population, rapid urbanisation, and vastly improved lifestyle coupled with unsustainable consumption patterns have all contributed to the growing waste crisis in the GCC. Among the GCC nations, United Arab Emirates has the highest municipal solid waste generation per capita of 2.2 kg (which is among the highest worldwide) followed closely … Continue reading

The Problem of Used Lead-Acid Batteries

Lead-acid batteries are widely used on a mass-scale in all parts of the world.  They act as power sources in a wide-range of equipment and appliances used by households, commerce and industry. Lead-acid batteries finds wide application in all modes of modern transport including cars, trucks, buses, boats, trains, rapid mass-transit systems, recreational vehicles etc. During power-cuts, lead-acid batteries provide emergency power for critical operations such as air-traffic control towers, hospitals, railroad crossings, military installations, submarines, and weapons systems. All automotive batteries and 95 percent of industrial batteries are lead-acid secondary cells. Harmful Impacts of Batteries Lead-acid batteries contain sulphuric acid … Continue reading

Methods for Plastic Wastes Collection

Plastic consumption has grown at a tremendous rate over the past two decades as plastics now play an important role in all aspects of modern lifestyle. Collection and disposal of plastic waste has emerged as an important environmental challenge and its recycling is facing roadblocks due to their non-degradable nature. There are four basic ways in which communities can offer plastic recycling collection services for plastic bottles and containers – curbside, drop-off, buy-back or deposit/refund programs. Curbside Recycling The first, and most widely accessible, collection method is curbside collection of recyclables. Curbside (or kerbside) collection is considered a low-risk strategy to reduce waste … Continue reading
