HIGH-EFFICIENCY UTILIZATION METHOD OF BIOMASS RESOURCES

摘要

PPROBLEM TO BE SOLVED: To provide a high-efficiency utilization method of biomass resources capable of realizing a high-efficiency utilization of biomass resources by making it possible to recover more amount of methane gas from a biomass, or the like. PSOLUTION: Methane gas yielded by methane-fermentation treating a biomass is recovered together with a methane yielded by hydrothermally treating a residue and a digestion liquid generated by the methane-fermentation treatment. Furthermore, a residue and a water solution except organic acids and oils among substances other than methane gas yielded by the hydrothermal treatment are recovered as carbides by carbonization treatment after drying them.
