An experimental study was piloted to evaluate the possibility of composting of source separated organic substance of municipal solid waste (MSW) produced in low, middle and high income areas of Peshawar having the a population more than 2 million. Outcomes of MSW investigation showed the occurrence of great proportion of Decomposable organic matter, adequate moisture content and C/N ratio. On windrow composting, not only the bulk of the waste was compacted but also formed a powdery earthy stinking soil-like, compost material. All valued factors in the compost samples were found to be within the acceptable limits set by international standard. The pH fluctuated between 7.5-8.1, moisture 35% and organic matter 43%, and has adequate quantity of plant nutrients C34%, N (0.06%), K (0.32%), P (0.004), Na (4.6%). The quality of compost could further be enhanced with the addition of yard waste or cow and poultry manure etc. For land reclamation or plant productions the use of compost may be supportive not only increase moisture holding capacity but also help to sustain soil conditioning. Composting through MSW could be introduced country wise as solid waste management option for the recycling and reuse of the organic remains.
