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

My Little Paper Recycling Project

Paper industry is considered as one of the world’s largest consumers of fossil fuels and biggest industrial polluter. The industry is criticized by environmental groups for being responsible for massive deforestation around the world. With the use of modern technology such as the printing press and the highly mechanised harvesting of wood, paper has become a cheap commodity. This has led to a high level of consumption and waste. Worldwide consumption of paper has risen by 400% in the past 40 years, with 35% of harvested trees being used for paper manufacture.  Paper wastes constitute as much as one-fourth of the solid … Continue reading

Waste Management in Jeddah

Jeddah, a major commercial hub in the Middle East, is the second largest city in Saudi Arabia. Solid waste management is a big problem in Jeddah as the city’s population is increasing at a rapid pace and has now touched 3.5 million. More than 5,000 tons of solid waste is produced every day and Jeddah municipal authorities are finding it increasingly hard to cope with the problem of urban waste. The management of solid waste in Jeddah begins with collection of wastes from bins scattered across residential and commercial areas. Wastes is collected and sent to transfer stations from where it … Continue reading

Environmental Best Practices for MENA Cement Industry

Cement production in MENA region has almost tripled during the last 15 years, mainly on account of high population growth rate, rapid urbanization, increasing industrialization and large-scale infrastructural development. The growth of cement industry in MENA is marked by factors that are directly connected with sustainability, energy efficiency and raw material supply. Although the factors differ from country to country and cannot be generalized, there are major concerns regarding shortage of raw materials, GHG emissions, dependence on fossil fuels and lack of investment in technological innovations. For the MENA cement sector, key points for an environment-friendly industry are use of … Continue reading

Environmental Initiatives in Middle East – Challenges and Remedies

Environmental protection has become an increasingly important item on the social and economic policy agenda of Middle East nations. As I read last week’s piece titled “Environmental Impacts of Plastic Bags” I was struck by the succinct summary of the main problems with the ongoing use of plastic bags and how their effects can be felt in many ways, some widely publicized and others not. The article prompted a series of reflections upon other environmental initiatives emerging in the Middle East and North Africa, especially in Qatar and the United Arab Emirates. In this article, I wish to share my … Continue reading

Waste Management Implications of 3D Printing

The rapid deployment of 3D printing is one of the most exciting developments since the appearance of the smart phone. This is technology with some serious potential to change how and where goods are manufactured, transforming supply chains. The New Scientist has gone so far as to herald 3D printing, also known as additive manufacturing, as ushering in a second industrial revolution. But is anyone thinking about how what this new development means for the waste sector? Whilst the technology is already being put to some dubious uses, the ability to manufacture pretty much anything wherever and whenever it’s needed is certainly appealing. Interest isn’t … Continue reading

Recycling of PVC – Prospects and Challenges

PVC, also known as Polyvinyl Chloride or Vinyl, is one of the most widely used plastics worldwide due to its chemical stability and durability. PVC products have an average lifetime of 30 years, with some reaching 50 or more years.  This means that more PVC products are reaching the end-of-life and entering the waste stream, and the amount is likely to increase significantly in the near future. The Middle East will ultimately have to deal with increased PVC waste as it is one of the markets expected to have high growth rates for PVC consumption, with developing countries in the … Continue reading

Hazardous Waste Management in Qatar: Progress and Challenges

A country with an abundance of raw materials, cheap labor, and a rising demand for energy, Qatar needed to diversify its industrial sector in the 1970s. From then onwards, the use of fertilizers, petrochemicals, and gas liquefaction plants have grown exponentially. The magnitude of hazardous waste and the pollution to be produced from different streams have not been thoroughly considered, but Qatar has taken serious steps to implement commitments for sustainable development by passing laws and treaties, such as law No.4 in 1981 issuing safeguards and providing requirements for the protection of the environment, and by signing onto treaties such … Continue reading

Recycling of Aluminium

The demand for aluminium products is growing steadily in the Middle East because of their positive contribution to modern living. Aluminium finds extensive use almost all walks of life including transport, food and medicine, packaging, construction, electronics and electrical power transmission. Infact, the use of aluminum exceeds that of any other metal except iron. Aluminium is the second most widely used metal whereas the aluminium can is the most recycled consumer product in the world.  Disposal Woes and Recycling Potential Disposal of aluminium wastes is a challenging task as aluminium exposed to fires at dumpsites can be a serious environmental problem in the form of poisonous gases and … Continue reading

Enumerating Benefits of Recycling

Recycling is the process in which used or abandoned materials from our everyday waste is converted into new products. Items that can be recycled include; glass, paper, plastics and various metals.  The process of recycling involves waste segregation after collection, processing the recyclable waste and finally manufacturing products from the waste thus processed. Need for Recycling Manufacturing products involves obtaining raw materials from various sources. Raw materials may be from forests or mines. They are then transported to the place of manufacture usually by land or sea, which is an energy consuming process. Procurement of raw materials and their transporting causes … 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

Introduction to MRF

A Material Recovery Facility (MRF) is a building to receive, sort, process and store recyclable materials to be shipped and marketed to end-users. A materials recovery facility accepts materials, whether source separated or mixed, and separates, processes and stores them for later use as raw materials for remanufacturing and reprocessing. The main function of the MRF is to maximize the quantity of recyclables processed, while producing materials that will generate the highest possible revenues in the market. MRFs can also function to process wastes into a feedstock for biological conversion or into a fuel source for the production of energy. MRFs … Continue reading
