Potential of Using Kitchen Waste in a Biogas Plant

Abstract

Abstract-India's economic growth is contributing to a massive increase in the generation of solid waste. Approximately 55 million tones of Municipal Solid Waste is generated annually by urban areas in India. Over 59% of homes in urban India use Liquified Petroleum Gas (LPG) supplied in portable cylinders for their cooking needs. However, due to our country's dwindling petroleum reserves and increased costly imports of petroleum, non conventional energy resources are slowly gaining importance. The use of biogas using kitchen waste as feedstock can help solve the problem of energy deficit and at the same time, allow the safe disposal of kitchen waste which is often unscientifically dumped or discarded. Our institute campus (Bhavans' campus) has a number of campus kitchens that utilize several LPG cylinders and also generate large amounts of kitchen waste. The kitchen waste generated has high calorific value and moisture content; hence it can be anaerobically digested. The biogas produced can be used to supplement the fuel requirements of the campus kitchens that generate the kitchen waste. This study consists of carrying out survey, characterization of kitchen waste from several kitchens and exploring it's potential to be used for biogas production.Index Terms-Biogas, municipal solid waste, kitchen waste, calorific value.

Design, Development and Testing of Screw Press Machine for Paddy Straw under Ground Digester

“…At present, all crop residues like paddy straw, potato tendrils, vegetable plants and tree leaves are being burnt in the fields just to make the fields clean for the next crops in short time. These crop wastes can be valuable fuel for kitchen the kitchen/ power generation [1]. Although at present, some of the crop residues are being used for power generation using thermal method which not only create atmospheric pollution but also produce a huge amount of ash for which disposal becomes a headache.…”

“…Igoni et al (2008) synthesised the key issues design of a high-performance AD. Apte et al (2013) identified the potential of biogas production based on the kitchen waste survey from several cities. Kayhanian and Hardy (1994) investigated the methane production rate as the contrary comparable to the moderate size of feedstock, the ratio of C/N organic, and the retention times.…”

Development and Optimization of Mild Steel Biogas Plant for utilizing Paddy Straw Residue

“…Grewal et al, [2] explained that the whole system in which anaerobic fermentation of cellulose containing organic material takes place and produce biogas, which accumulates in gas holder or the dome, then utilization of this gas through the gas pipeline under suitable pressure is called biogas plant system. Initially cow dung was mainly used as fermentable material for biogas production of biogas.…”
