PROCESS FOR THE DIGESTION OF ORGANIC MATERIAL

摘要

The present invention provides a process for the digestion of organic material into biogas which comprises: - pretreating the organic material by thermal treatment, mechanical treatment, chemical treatment or any combination of these treatments; - treating the pretreated organic material with at least two carbohydrases to obtain a weight ratio of soluble oligosugars to monosugars of between 1000 : 1 and 1 : 1; - separating the liquid fraction from the solid fraction of the enzyme-treated organic material; and - digesting the liquid fraction to form biogas.
