Large to medium size educational institutes generate sufficient amount of kitchen waste. The disposal of this waste is a major problem. This waste has good biofuel value and called as a Green Gold. Total waste generated by medium to large size educational institution is around 600Kg/day, which can be used to generate Biogas. The kitchen waste generated from vegetable waste and remaining food contains a high amount of organic substances. This can be utilized to produce biogas by an anaerobic fermentation process. These anaerobic bacteria eat the waste and produce methane (CH₄) which is a major constituent of biogas. The proper mixture of water and solid waste is important to produce the gas in the gas holder tank. Initially, gas generation takes 30 days but after digestion of anaerobic bacteria, it produces biogas continuously. The gas generated through this process contains some impurities which reduce the efficiency of combustion and calorific value of the fuel. This project aims to produce design methodology which can produce biogas with high methane content from given input waste capacity.  

The biogas plant designed in campus produces biogas to run D. Y. Patil Hospital canteen daily for 2 to 3 hrs on biogas in place of LPG. This biogas can also be used in the electrical generator to produce electricity of around 1.2kW
