Overview of Technology for Conversion of Unused Biomass into Alcoholic Fuels - April 2002
Alcohol fuel technology for unutilized biomass is a technology for converting normally discarded agricultural waste, forest residues, construction waste, etc. into alcohol fuels such as ethanol and methanol. This technology is carried out through the processes of biomass decomposition, saccharification, and fermentation. Agricultural waste (rice straw, bagasse, etc.), forest residues (thinned wood, branches and leaves, etc.), and construction waste are mainly used. Utilization of unused biomass contributes to waste reduction and greenhouse gas emissions reduction, and provides a sustainable energy supply. However, the economics of the technology depend on cost reduction, and the challenge is to bring it down to a level that is competitive with gasoline. Demonstration plants are currently being set up in Japan and are expected to be deployed on a commercial scale. The advancement of this technology is expected to reduce dependence on fossil fuels and contribute to the realizat
ion of a sustainable society in the future.
