Pollution Control Board, Vijay Nagar Jabalpur (M.P.), India 2  Department of Biological Sciences, Mycological Research Laboratories, R.D. 3 University, Jabalpur (M.P.), India, 482001 Abstract:  A pilot study was conducted to asses the feasibility of composting of source separated organicmatterof municipal solid waste (MSW) generated in low, middle and high income areas of Jabalpur city witha population over 5 lack. Results of MSW analysis indicate the presence of high percentage of Biodegradableorganic matter, acceptable moisture content and C/N ratio. On windrow composting, not only the volume of thewaste was reduced but also produced a crumbly earthy smelling soil-like, compost material. All quality parameters in the compost samples were found to be within the acceptable limits set by international standard.ThepH ranged between 7.8-8.1, organic matter 45%, moisture 36% and have acceptable amount of plantnutrients C35%, N (0.05%), P (0.002), Na (4.8%), K (0.35%). The compost quality could further be improved byadding cow manure, poultry manure or yard waste etc. Its use in plant production or land reclamation may behelpful to maintain soil fertility and improve moisture holding capacity. MSW Composting could be adaptedcountry wide to recycle/reuse the organic residue as solid waste management option.
