Biogas as a result of a process of fermentation of different organic materials ( all materials derived from living things) is a renewable energy source that can be obtained at minimal cost. The gas formed in the tube-tight ( without oxygen) Biogas Digester BD 5000L is strong, made   of resin eternally 2504, this type of mat Wr 200 ( woven mat) and mat 300 ( random) , the thickness of 3-5 mm, able to ferment 5 m3 per cycle . Trash and other organic materials can be continuously added to the intake hole, and will be parsed by anaerobic bacteria Green Phoskko ( GP-7) , only 5 days have started to release methane gas ( CH4) and stored at the top of the tube ( gas holder) . Capacity 5 m3 of material inputs plus 2 m3 of gas holders, had a dimensions ( diameter 200 cm, height 390 cm) , will persist until more than 5 years. Produced by complete knock down, complete with the installation of gas pipes, stove manufacturer standards and supporting equipment for the utilization of methane gas as an environmentally friendly fuel.
