Abstract

In developing countries, the biodegradable component of municipal solid waste is typically composed of 40-60% kitchen waste. Composting is a globally accepted technology for clean and sustainable management of organic waste. This study attempts to assess three domestic composting systems, Kamba (clay pots), rotary drum, and bin composting. Technical and economic features of the systems were also discussed and compared. During the composting process greenhouse gases are generated, mechanisms to reduce the greenhouse emissions are noted. Composting and Bokashi systems are compared in terms of process mechanisms, the quality of end products, operation and maintenance process. The domestic composting process reduces the pressure on the collection and transportation components of municipal solid waste management. This review provides an insight into the development of strategies for municipal solid waste management at the household level.
