Abstract

The invention relates to a method for producing biogas from biomass using anaerobic digestion wherein biomass is fed as input to a reaction space using mechanical feed equipment while simultaneously advancing biomass contained in the reaction space as plug flow. Biomass is mixed separately in each block in the reaction space divided into successive blocks for feeding biomass to block-specific microbial strains. The number of blocks is at least three each comprising its own main microbial strain. Biogas produced as the result of anaerobic digestion of biomass is recovered. The microbial strain of each block is fed in front of the corresponding block and, in at least two of these blocks, the feed is reject obtained from the block as high consistency stock. The invention also relates to a corresponding reactor.
