Today Mumbai is facing the problem of waste accumulation in different areas and limitation of waste disposal sites. These wastes are dumped in the form of big heaps. The degradation of these waste starts after few days. The process of degradation is aerobic at outer layer and anaerobic at inner layers. Due to these reactions, putrescible gases are come out and causes the health hazard. The Bio-CNG plant gives the best solution for this problem. It uses the vegetable waste as raw material and converts it into a high calorific value fuel. Hence it minimizes the waste accumulation and also solves the problem of energy crisis at the same time. In this study 6kg waste is digested under controlled environment condition n a mesophilic temperature range(30°C-45°C) for 26 days to obtain Biogas. The Biogas so obtained contains CH₄, CO₂, H₂S, and Moisture content. The presence of CO₂, H₂S, and Moisture content in Biogas is considered as impurities as it reduces the calorific value of fuel and hence removed using three scrubber units to obtain the composition of natural gas.These three scrubber units contained Sodalime, Silica gel, and Tri-ethylene glycol to remove CO₂, H₂S and moisture content respectively. The Bio-CNG obtained above contains more than 85% of CH₄ which has high calorific fuel value. These Bio-CNG can be used as automobile fuel, for cooking as well as for power generation. It can also be considered an alternative fuel option against the limited stock of conventional fuels like coal, petroleum etc in future.
