Abstract (en)
[origin: CA2682008A1] The invention relates to the fields of biochemistry and energy generation and relates to a method for the fermentation of ensilaged renewable raw mat erials that may be subsequently used in a biogas production facility and hav e improved properties due to the pretreatment according to the invention. Th e method according to the invention may be used in the monofermentation of r enewable raw materials and in co-fermentation with commercial fertilizers (f or example, liquid manure) in agricultural biogas facilities or in co-fermen tation with sewage in community sewage systems. The aim of the solution acco rding to the invention is to provide a method by which the total times for t he production of biogas are reduced and a lower fluctuation in quality of th e produced biogas is achieved. This aim is attained by a method in which ens ilaged renewable raw materials are first washed and mechanically comminuted, then the washed and comminuted ensilaged renewable raw materials, from whic h at least part of the washing water has been removed, are subjected to a se parate hydrolysis, after which the hydrolysis products are subjected to the known method for the production of biogas in fermenters.
