All material biomass (organic material from plants, animals and humans as well as waste) is mixed with water in a certain ratio, then put / streamed to the digester tank (biodigester tank) in the absence of air (anaerobic), will naturally produce biogas. Charging is done every day, through the intake holes (inlet chamber) to the extent, according to its maximum capacity, the biogas will come out by itself and will be accommodated ditangki shelter of biogas (gas holder) on the upper tank digesters.

Biogas will exit upward through a pipe leading to the holding tank (outlet chamber), once purified from impurity gas, biogas will be biomethan (CH4 content of> 70%). This gas will have the energy equivalence of heat such as Compressed Natural Gas (CNG) and ready to be discharged home stair pressure compressor for cooking and / or illumination through pipelines (gas outlet pipe), or can also be used as fuel burning electricity generator. One of the completeness of the system was presented 2 Biogas Stove Furnace.
