ABSTRACT
This paper presents about Solid waste management using Biomethanation technology in Pallipalayam municipality.
The Pallipalayam municipality is situated in Kumarapalayam taluk of Namakkal district. Pallipalayam is a second grade
municipality. It is twin city of Erode. The process of Methanogenesis by which organic waste materials are converted an
aerobically into methane rich biogas by micro-organism has been studied intensively in recent years. Biomethanation is a
feasible method to generate the biogas from organic waste like food waste, human waste, night soil waste, cow dung etc. so we
implement the automation in biomethanation plant. This plant has four major processes like waste collection and mixing,
digestion, gas collection and gas distribution. Methanogenesis follows three basic process, as an initial step of hydrolysis of
complex molecules to simple molecules. An acidification step in which the products of hydrolysis such as glucose, long chain
fatty acids, peptides, amino acids are metabolized to form volatile acids, aldehydes, alcohols, carbon dioxides and hydrogen.
Methanogenesis step in which formation from Co2, H2 and acetate brought about by methanogenesis bacteria. It is generally
considered that methanogenic step is rate limiting step. As well in the digestion of cellulosic waste hydrolysis of organic acids
rather than methanogenic waste. The generation of electricity by the gasification process.
