Abstract:
Biomass, that is carbon neutral and a renewable resource, becomes attractive after thedecision of Biomass¬Nippon strategy in Japan. Especially, bioethanol as transportationliquid fuel from biomass is attractive in the world. However, food price is increased by theattractiveness because sugar and/or starch are used as feedstock for bio¬ethanol. Therefore, bioethanol production from lignocellulosic biomass is desired in order to avoid the increase of food price. From these situations, we are studying bioethanol production from lignocellulosic biomass using mechano¬chemical pulping pretreatment. On the other hand, the ethanol production cost of 40 JPY/L¬EtOH is desired as Innovation case in Biofuel Technology Innovation Plan. Additionally, GHG emission from bioethanol is also important. In this study, economic and environmental analysis for bioethanol production from lignocellulosic biomass using mechano¬chemical pulping pretreatment were performed byprocess simulation. In the analysis, commercial scale plant (1,000 wood/day, around 100,000kL¬EtOH/yr) was assumed. From the analysis, it was found that the production cost decreased to one fourth when the targets in each step (cultivation of biomass, collection, pretreatment, enzymatic saccharification, fermentation, distillation and dehydration) were achieved. GHG emission of bioethanol was less than 50% of that of gasoline.
