METHANE GENERATION SYSTEM AND METHANE GENERATION METHOD

WIPO Patent Application WO/2023/136104

A1

This methane generation system (1) comprises an alkali treatment unit (20) for bringing a lignocellulose biomass and an alkali solution into contact with one another to generate an alkali treatment solution containing a first solid component and a first liquid component, a saccharification unit (40) for decomposing the cellulose and/or hemicellulose derived from the lignocellulose biomass contained in the alkali treatment solution using saccharifying bacteria to generate a saccharified solution containing a second liquid component, an acid generation unit (60) for generating an organic acid from a mixed solution containing the first liquid component and the second liquid component using acidogenic bacteria, and a methane generation unit (70) for generating methane from the organic acid using methanogens.
