Abstract - Growing urbanization and industrialization have led to generation of large quantities of wastes. Major portion of Municipal Solid Waste is dumped in landfill sites without any pretreatment, which further creates the organic load on the ground water, and more emissions of landfill gases. The best possible option to reduce the potential pollutants before entering the natural biological system is to pretreat it prior to its final disposal. Here, an outdoor study was under taken to pretreat the Municipal Solid Waste collected from a vegetable market on a pilot scale by windrow composting and vermicomposting. The raw waste was put to dynamic composting without any source separation and pulverization. Pretreatment indicators were developed and are used as a tool to measure the stabilization of the waste under different conditions, periodically. It was investigated that the volatile solid content of the waste reduced from 86 % to 60 % within two weeks of active windrow composting. The volatile solid content in the vermicomposted waste was also reduced by 19%. The degradation of organic matter was greatest within the first week of active composting with an average pile temperature of 55⁰C. Furthermore, by adding proper amount of sludge from waste water treatment plant to the raw waste, resulted to a greater breakdown of organic residues, which ultimately resulted in a lowering of C/N ratio from 43 to 24 within one week
