Part of the challenge with biomethane is the complexity of the anaerobic digestion process itself. Although a wide range of feedstocks can be used to produce biogas in digesters, Kari-Anne Lyng, senior researcher at the Norwegian Institute for Sustainability Research, says that they all have different levels of protein and other compounds such as ammonia. The microbes that digest these feedstocks do their job best when such molecules are well-balanced. If they're not, the environment within the digester becomes toxic to the specific microbes inside it that make the methane. Keep reading :  โรงเรียนบ้านยูงงาม
