Progress in biomass energy studies in the Ministry of Agriculture, Forestry, and Fisheries of Japan
2003
Mori, Y.
The Ministry of Agriculture, Forestry, and Fisheries (MAFF) of Japan has been studying biomass energy development for more than two decades. The major focuses of the studies are biomass production and biomass conversion to energy. The representative results of the biomass energy production studies are (1) a novel steam gasification system for methanol production from biomass, (2) the technologies of converting cellulosic and hemicellulosic materials into ethanol using a naturally occurring bacterial coculture and genetically modified enzymes, (3) the membrane technologies for ethanol separation and concentration, and (4) a semisolid methane fermentation system for swine excreta. Rice husk, straw, and bran are among the major biomass resources in Japan. These rice residues were tested as feedstocks for biomass energy production. Biomass energy studies by MAFF, including the results with rice residues, are presented and future directions for biomass energy development together with the potential of rice as energy and a material resource are discussed.
