State-of-the-art systems report producing biogas that is more than 95 percent pure methane. Thus, for enhancing biogas production, a higher digester temperature than ambient temperature is required. If straw and dung are to be digested together, a biogas plant can be operated on a semi-batch basis. 2 Mechanism of biogas fermentation: A) Groups of Biogas microbes - B) Groups of microbes involved in the 3 stages of biogas fermentation - 1st stage: Fermentative bacteria-. 3 Biogas basics A biogas plant comprises structures for the production, storage, movement, handling and utilisation of biogas. The bacteria are also active in landfills where they are the principal process degrading landfilled food wastes and other biomass. Biogas, the gas generated from organic digestion under anaerobic conditions by mixed population of microorganisms, is an alternative energy source, which has been commenced to be utilized both in rural and industrial areas at least since 1958. For example: a biogas plant using or-ganic wastes or residues like the was-tes from the food industry, food scraps, grease traps or slaughterhouse wastes are required to hygienise the material - meaning to treat them over a defined Sector handbook biogas 6. The results indicate that utilising biogas for the boiler gives higher economic returns compared with the other three options, given certain conditions. This represents approximately 60 l of biogas, which is 60% methane, that would be produced from a semirustic, or technologically -poor, plant. The biogas. However, the utility serving a WWTP plant may apply a different, standby electricity rate for a WWTP that self-generates.
