Dry Digester

Dry fermentation is a special process for the biogas production. Over the years we gained different experience by implementing dry digestion projects on our customers’ sites. Due to this longstanding knowledge we provide you with reliable concepts and designs. In general, relatively dry, fibrous biomass containing impurities can be effectively digested by dry fermentation. For instance typical application examples are bio-waste from separate collection, organic fractions from residual waste, manure or green waste. These bio waste applications are not suitable for wet fermentation biogas plants. Therefore we offer a product solution especially for dry fermentation.
