A review of the reported technologies to segregate municipal solid waste into dry and wet waste based on their moisture content

Koustuvmoni Bharadwaj, Kalyan Kumar Das


This paper deals with the various techniques used to segregate municipal solid waste based on its size and types. We study various research works and ongoing industry practices and finally summarize a general process that is being used to segregate municipal solid waste. This paper also addresses the major problem related to segregating waste as wet and dry and the existing technologies that are being used in industries to segregate municipal solid waste. The methods used to detect moisture in waste materials, are also discussed along with their pros and cons. For this study, we have considered the practices used to segregate waste in India and how they can be improved by implementing the technologies used in other countries in the existing Indian waste management scenario.
