The following paper describes production of biogas and purification of biogas. We have performed experimentation on biogas production. The raw material used for biogas production are kitchen wastes. The paper describes the Anaerobic digestion process used for biogas production. This paper describes the properties the properties of biogas like colorless odorless, etc. and advantages and disadvantages. Biogas has numerous purposes and also can be as the energy source. Biogas involves different components of gasses like Methane, Carbon Dioxide, Hydrogen Sulphide, and moisture content. Purification biogas means removal of Carbon Dioxide, Hydrogen Sulphide, and moisture content.
