Biogas is a process of bio gas production from organic materials with the help of bacteria. The process of degradation of organic materials without involving oxygen is called anaerobic Digestion gases produced largely (over 50%) of methane. organic material accumulated in the digester (reactor) going diuraiakan into two stages with the help of two types of bacteria. The first phase will orgranik material degraded to acid weak acid with the aid of acid-forming bacteria. These bacteria will describe the level of waste and asidifikasi hydrolysis. Hydrolysis of complex compounds decomposition or long chain compounds such as fats, proteins, carbohydrates into simple compounds. While the formation of acid asifdifikasi of simple compounds.
After the organic material into acid acid, then the second stage of Anaerobic Digestion is the process of formation of methane gas with the aid of methane-forming bacteria such as methanococus, methanosarcina, methano bacterium.
Development of Anaerobic Digestion process has been successful in many applications. This process has the ability to process the garbage / waste overflow exists and is not useful to more valuable products. Anaerobic Digestion application has been successful in processing industrial waste, agricultural waste and livestock waste municipal solid waste.
