Biomethane (contains over 95% methane) is biogas purified to the high-methane gas standard (contains 50-60% methane, 25-40% CO2 and other additional compounds created in the fermentation process). A biomethane plant is a biogas plant with an appropriate installation for purifying biogas to biomethane. A simplified conversion of biogas to biomethane is 1 m3 of biogas = 0.6 m3 of biomethane. A biogas plant, at least in Poland, is a waste processin…
