| Outline of Final Research Achievements |
Effective utilization process to convert all components of unused woody biomass into epoxy resin and methane, which is a raw material of hydrogen for fuel cell, was developed to use biomass not only for energy production but also for material synthesis in this study. This process consisted of steam steaming and milling as a pretreatment, extractions using water and acetone, methane fermentation from the extracted residue, and epoxy resin synthesis from the extract was optimized. 18.8 g of epoxy resin raw material and 72.3 g of methane raw material were obtained from 100 g of treated biomass sample, i.e. BODE, at a steaming temperature of 224℃ and a steaming time of 5min. The synthesized epoxy resin had an almost same functionality as a conventional material, and 67% of methane yield to the theoretical value was obtained in the methane fermentation of the residue after water and acetone extractions.
