Biomass resources come to public notice as a part of the development of alternative energy. The special features of distribution of resources by the metropolis and districts were grasped and the biomass resources in Hokkaido as the model district were surveyed in detail. The amount of existing biomass resources in Japan is approximately one and a half billion tons and the forest land accounts for 94% of it. The amount of production of biomass and amount of available energy are approximately 160 million tons and approximately 100 million tons, respectively. Since the amount of production of biomass in Hokkaido is only 14% of that in Japan though the amount of existing biomass resources is 22%, the production capacity per unit area of land must be increased. The productions of alcohol from glucide and starch and the recovery of silicon for semiconductor (seven times the nationwide production) from rice hulls are promising. The productions of methane and compost from the other resources are expected. The promising areas of biomass resources in Hokkaido are Obihiro, Asahikawa and three regions along the shore of the Sea of Okhotsk. (21 figs, 29 tabs). (ERA citation 13:021140)
