Biogas is a renewable energy source which can be generated by decomposition of organic waste. The biogas pilot plant refers to the design of the biogas plant being used for minimal purposes & requirements. The reference of the design for the plant is the existing floating dome type structure. Some modifications in the existing referred design are being made to make the plant portable. The apparatus will be used to generate power by the means of a generator and an electrical circuit connected to it. The generator will be powered by the biogas being generated in the tank. The research is carried out to increase the productivity of the gas & and to check for the increment in the efficiency of gas produced by mixing additives, varying the constituents of slurry & pre-treatment of waste.
