Waste management, eco friendly, health care and employment foundation are the benefits of biogas system. Use of biogas technology assures renewable energy supply and balance of green house gases. India is using biogas since long time but there is need of advancement in the technology, Bio energy should be used in urban and rural so that it can help government to diminish both the import of fuel derivatives and solid waste processing and management cost. The aim of this paper is to highlight importance of this technology to bring social and economical changes to India. In this work, biogas digester was fabricated and analyzed to investigate bio gas generation using kitchen waste. Keywords— Kitchen Waste, bio energy, biogas, sustainable energy, Biogas Plant. I. INTRODUCTION Worldwide energy consumption and demand are growing up since past 50 years. Most of the resources used like petroleum, natural gas, coal are not sustainable sources of energy.[1] Numbers of countries in the world including India are currently passing through the critical phase of population explosion and the growing population demands more energy inputs. In India there is deficiency of energy in required form to meet national developmental needs. [2] Raw vegetables wastes are used to produce biogas by anaerobic digestion process from a long time because in principle, it has high energy potential and enormous quantity of vegetable wastes are dumped daily in municipal and urban areas which needs to be processed to minimize environmental pollution. Even though anaerobic digestion is an old and proven technology, process design for efficient energy production is not fully understood and research and development work is going on to improve efficiency, reliability and applicability. [3-5] Literature shows that many works have been carried out in India and abroad for production of biogas using farm wastes, sewage sludge, and municipal solid wastes (MSW) etc. It is clear from review that there are no common governing factors that indicate the suitability of any particular reactor design for a specific effluent. By suitable modifications in the reactor designs and also by altering the influent physio-chemical characteristics, high rate digesters can be accomplished for the treatment of organic waste. II. LITERATURE REVIEW 2.1 Ezekoye, V. A, Onah, D. U, Offor, P. O. & B. A. Ezekoye[1]: Ezekoye did the experiment Rice husks and algae plan substrates where successfully used to produce biogas. A metal fixed-dome bio digester (bioreactor) was used for the characterization of the biogas generated from these plants wastes. As in the figure 1, A total of 35 kg of slurry (sludge) made from 5 kg of rice husks and 30 kg of algae were mixed in water in the ratio of 1:6 and fed into the bio digester (bioreactor). The digestion of slurry was undertaken in batch- type anaerobic digestion and mesophilic temperatures range at 29.00oC 33.45oC. For over period of 75 days, the cumulative biogas produced from the wastes was 156.25 liters. The percentage of the methane component of produced biogas was 52.3% .The biogas from the seeded rice husk was combustible on the 45th day. This result that many of the microorganisms associated with the fermentation of rice husk and algae from sewage pond originated from the inoculums and substrate used. Also since the population of the microbes in the digester was increased by addition of the inoculums, there was fierce competition for the limited substrate, and the intensity of this competition depends on the net population of the microbes in the digester. This is the determinant factor for the retention
