The purpose of this study is to evaluate available woody biomass potential in Japan. Quantity of unused woody biomass is estimated and evaluate the feasible quantity within unused woody biomass by designing woody biomass utilization system. Target area is Tohoku region in Japan, and target esources are factory waste and construction waste, which are industrial waste, thinning branches and forest wood residues, which are forestry waste, fruit tree branches, which are agricultural waste. Cost, C02 emission, and energy balance of the system is evaluated to uncover availability of woody biomass. In this study, actual available quantity of woody biomass is evaluated by designing biomass utilization system using co-firing technology with coal. ln addition, effect of setting forest road to biomass potential is evaluated
