Rapid composting of biodegradable waste through passive aeration

Abstract

Composting of municipal solid waste (MSW) as a part of Bio-processing is of much concern. Since it gives sanitary approach for processing as well as enables geochemical cycling of the nutrients. However, due to the quality of the compost formed, there is no sufficient demand for it. Moreover, due to low yield of compost and mechanization used in its preparation, the resultant cost is not affordable by the farmers. Pretreatment of MSW with NaOH and Na2CO3, as observed from chemical oxygen demand of the supernatant shows more carbon solubilization from the waste.
