Case Studies

According to the Knowledge Product (KP)studies commissioned by the Department of Environmental Affairs (DEA), Pyrolysis is the thermal degradation of a substance at high temperatures in the absence of oxygen. It involves the simultaneous change of chemical composition and physical phase, is irreversible and requires a relatively consistent waste stream. Use was made of manual provided by GreenCape and approved by the Western Cape Department of Economic Development and Tourism, ‘Towards int...

According to the Knowledge Product (KP) studies commissioned by the Department of Environmental Affairs (DEA), mechanical biological treatment (MBT) combines both mechanical and biological treatment methods (open windrow composting, materials recycling facilities, anaerobic digestion and in-vessel composting). These are supported by a combination of pre-treatment and sorting techniques at the beginning of the process, and a selection of emissions control and quality control techniques at the end...

According to the Knowledge Product (KP) studies commissioned by the Department of Environmental Affairs (DEA), incineration is the direct combustion of urban solid waste material coupled with subsequent energy recovery. The heat resulting from the combustion process can be used to generate heat and electricity through a steam circuit system. This is referred to as a combined heat and power process (CHP). Use was made of the manual provided by GreenCape and approved by the Western Cape Department...
