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

Dealing with Polystyrene Wastes

Polystyrene (also known as EPS Foam or Styrofoam) is a highly popular plastic packaging material which finds wide application in packaging of food items, electronic goods, electrical appliances, furniture etc due to its excellent insulating and protective properties. Polystyrene is also used to make useful products such as disposable cups, trays, cutlery, cartons, cases etc. Despite the attractiveness of polystyrene, municipalities and organisations are facing a growing problem in disposal of polystyrene packaging and products. Being large and bulky, polystyrene take up significant space in rubbish bins which means that bins becomes full more quickly and therefore needs to be emptied … Continue reading

Towards an Eco-Friendly Eidul Adha

Eidul Adha, like other religious festivals, often has a major impact on the environmental resources. Extra food, drinks and clothes are made, used and consumed which results in a major environmental footprint. The celebrations and festivity are often extravagant and cause pollution of different forms. The day starts with the special prayers whereby men, women and children gather to offer prayers. The site of praying after the ritual is often plagued by litter, rubbish and waste scattered all over the place and even blowing in the air and migrating to nearby safe heavens for unaesthetic and unhygienic accumulations. Muslims on Eid … Continue reading

Towards a Waste-Free Ramadan Iftar

In the holy month of Ramadan, Iftar or breaking of fast becomes our main attention. The Iftars are either taken at home alone or with the family and relatives or at Iftar buffets at hotels and restaurants.

Disrespect to Food It is a common sight that at Iftar, people do not respect the food and drinks that are provided … Continue reading

Construction Wastes Management in the UAE

Out of total solid wastes generated in the UAE, the construction and demolition wastes or (C&D wastes) account for 70% of the total weight of solid wastes. Dubai alone produces nearly 5,000 tonnes of construction and demolition waste every day, which is about 70% of the total solid waste generated every day. In Abu Dhabi, C&D wastes account for 71% of total wastes generated. It is expected that construction and development activities and associated C&D waste production will continue to rise in this region. Hence, if not managed appropriately, it is expected that dumping of C&D waste will become uncontrolled. … Continue reading

The Menace of Littering and How to Solve It

Littering is a common menace one can witness in all urban areas. Streets, sidewalks, parking lots, roads and highways are mostly covered with food wrappers, soft drink and water bottles, plastic bags, handbills, cigarette butts, tissues, papers and others. Littering is most likely to take place at locations where litter is already ‘present’. The Growing Menace of Litter Around 1.9 billion tonnes of litter end up in the ocean every year, which clearly shows that people tend to throw things randomly anywhere, more often than they throw waste in garbage bins. Litter is not just an ugly or an aesthetic … Continue reading

Environmental Best Practices in the Cement Industry

Worldwide, cement production  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 cement sector, key points for an environment-friendly industry are use of alternative raw materials … Continue reading

The Unending 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. Why Do We Need 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 … 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 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 the … 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

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. 1. Thermochemical Conversion of Waste The three principal methods of thermochemical conversion of MSW are combustion (in excess air), gasification (in reduced air), and pyrolysis (in … Continue reading
