Composting of municipal solid waste

This paper reviews the literature on the composting process, which is one of the technological options for the processing of municipal solid wastes (MSWs). The process assumes a great significance, particularly from the point of its economic viability, capability for recycling of nutrients and waste minimization with minimum environmental problems. A number of studies on various aspects of the composting process, including process control and monitoring parameters such as temperature, pH, moisture content, aeration, and porosity are reviewed. Salient observations on microbial properties of composting are described and details of vermicomposting, as well as a detailed analysis of patents on composting of MSW, are presented.
