Evolution of Bacterial and Fungal Flora during In-Vessel Composting of Organic Household Waste under Air Pressure

This study aims to evaluate the performance of a laboratory-scale in-vessel composting of the organic fraction of municipal solid waste in Morocco. The bioreactor was specifically designed and used for this study and was operated in semi-continuous under air pressure. The studied parameters included operational indices, compost maturity indices, changes in bacterial and fungal flora, and final compost quality. Results showed that the organic fraction of municipal solid waste could be composted successfully in 60 days, revealing a vigorous microbial activity. The final compost was satisfactory for its agricultural application. Received 03 Oct 2016, Revised 30 Oct 2016, Accepted 26Nov 2016
