Abstract: The sight of a dustbin overflowing and the stench rising from it are all too familiar sights of a crowded city. As we cross it, we look away from it and hold our nose. If we give a thought to it, we also have a role to play in the creation of this stench. We can also play a role in the lessening of this smell and reducing the dumping of the waste, if we follow proper methods of disposal of the waste generated in the house. The growth of urban cities and ever increasing human population and the misuse and abuse of the environment has led to increased accumulation of waste materials which is polluting water, air, soil and increased risk to human life in the form of epidemics. There are number of methods for solid waste management from ancient times. Some of the methods are sanitary land-fill, vermicomposting, burning, incineration, biogas generation, anaerobic composting. These methods will not prove effective in some of the circumstances such as high temperature, high moisture content. So, there is need to find such a method which suites to all the environmental conditions & circumstances. The above said problems can be solved by the new method of waste management viz. Mechanical Biological treatment (MBT). In this method, the culture called mega-bacillus is considered as key agent for degradation of organic waste. In the present study, kitchen waste is decomposed using mega-bacillus. A total quantity of 20 kg green waste was converted to 4.074 kgs of manure in just 16 days with a pH of 7.96, C : N ratio of 25.07:1 and a Nitrogen content of 2.15% which are within the desirable parameters for increasing the yield of crop & maintaining the fertility of soil
