Dry Digester

Dry anaerobic digestion is a special process for the biogas production that works at high dry matter content inside the digester. In general, relatively dry, fibrous biomass and materials containing contaminants can be effectively digested by dry digestion. For instance typical application examples are bio-waste from separate collection, green waste, or organic fractions from residual waste. Over the years we gained experience by implementing dry digestion projects on many customers’ sites, with all kinds of digester designs. Due to this longstanding knowledge we provide you with reliable concepts and designs.
