Ramaiah Institute of Technology, Bangalore-54, Department of Mechanical Engineering, assistant professor CMR Institute of Technology, Bangalore, Professor, Head of Department of Mechanical Engineering A plug flow reactor is an insulated and heated tank made of reinforced concrete, steel or fiberglass with a tight cover to capture biogas. <...> Biogas is produced by the fermentation of organic matter including manure, sewage sludge, and municipal solid waste, under anaerobic conditions. <...> Fiberglass is the material used for construction. <...> This biogas plant is to be kept indoors, therefore it fits in and do not consume too much space. <...> The unit is also strong enough to hold around 0.857 m3 (857 liters) of slurry (water and waste mixture) and be easy to transport from one place to another. <...> Biogas is produced by the fermentation of organic matter including manure, sewage sludge, and municipal solid waste, under anaerobic (having no oxygen) conditions [1]. <...> A biogas plant is an anaerobic digester of organic material for the purposes of treating waste and concurrently generating biogas fuel. <...> This concept is suited to distributed systems where waste is treated near the source, and sludge is also reused locally to minimize transport and initial capital cost [4]. <...> Current study is aiming at this where biodegradable household waste will be treated as an energy source, and end product (biogas) can be effectively used which intern will be useful in two ways such as solid waste management and energy production at lesser cost [5]. <...> The methanogens (methane producing microorganisms) can digest sugar, starch, fats, cellulose, and proteins but not lignin. <...> Methanogens convert acetic acid into methane and carbon dioxide. <...> At this temperature and pH, they can convert food waste into biogas within about 24 hours. <...> One kilogram (dry weight) of food waste can be converted into about 1 kg (about 800 liters) of biogas. <...> Other organic products like plastic, rubber, petroleum, or wood cannot be digested by the methanogens. <...> Adding any toxic <...>
