Leave a comment

Thermal (or thermochemical) MSW-to-energy conversion systems consist of primary technologies which convert the municipal waste into heat or gaseous and liquid products, together with secondary conversion technologies which transform these products into more useful forms of energy, such as heat and electricity. A wide array of thermal waste-to-energy technologies are available to convert the energy stored in solid wastes into more useful forms of energy. These technologies can be classified according to the principal energy carrier produced in the conversion process. Energy carriers are in the form of heat, gas, liquid and/or solid products, depending on the extent to which … Continue reading →

The MENA region produces huge quantity of municipal wastewater which represents a serious problem due to its high treatment costs and risk to environment, human health and marine life. The per capita wastewater generation rate in the region is estimated at 80-200 litres per day. Sewage generation across the region is rising by an astonishing rate of 25 percent every year. Municipal wastewater treatment plants in MENA produce large amounts of sludge whose disposal is a cause of major concern. For example, Kuwait has 6 wastewater treatment plants, with combined capacity of treating 12,000m³ of municipal wastewater per day, which produce around … Continue reading →
