<p><P>PROBLEM 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. <P>SOLUTION: 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. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
