Composting can be defined as a process of controlled decomposition of organic fraction of municipal solid waste (msw) into stable humus like end product. Composting has proven to be both economically viable and eco-friendly process to treat municipal solid waste. It not only causes notable reduction in solid waste but also produces a stable end product which can be used as a soil conditioner. However currently advanced techniques for composting are being investigated to overcome the problems associated with traditional composting systems. Problems such as lower composting rate, large area requirements, costly mechanized systems associated to traditional processes can be suitably eliminated by using advanced techniques. In this paper we have tried to study the application of various additives in various modes. A reactor has also been constructed to imitate an in-vessel composting system with aeration mechanism and turning facility. Results have shown optimization of various parameters for various modes. Use of the commercially available inoculum has shown fruitful results regarding composting duration, process parameters and final compost product. The final product obtained had a considerable C:N ratio which can validate that it can be used as a mature compost and can be used to initiate a new composting process. Besides, promotion of such reactors is necessary to alleviate solid waste management issues at local levels.
