Abstract
The present invention relates to a method of treating organic materials to produce methane gas, comprising the steps of: a) subjecting an organic feedstock comprising organic materials to a liquefaction process at subcritical conditions in at least one reaction stage, to obtain a mixture containing low molecular weight materials and optionally lignins; b) subjecting the obtained mixture containing low molecular weight materials and optionally lignins, to a methane fermentation process; wherein said organic feedstock comprises liquid water and/or is combined with liquid water before and/or during said liquefaction, and the subcritical conditions for said at least one or more reaction stage(s) in a) is a temperature of 280-374° C. during a reaction time of less than 1 minute, wherein if more than one reaction stage is used in step a) the obtained mixture after each reaction stage is subjected to a separation of the produced low molecular weight materials from the remaining solid materials of the treated feedstock.
