7-3-3 間伐材利用によるエネルギー供給ポテンシャル量と負荷の推計

神奈川県松田町の事例調査

Currently, thinning is not progressing in many forests, and local governments are struggling to manage them. The reason why thinning does not progress is high cost of thinning and low merit for the owner of the forest. On the other hand, many local governments have attempted to introduce biomass energy, but it is difficult to achieve profitability without special support and subsidies, and there are few successful cases. Therefore, by introducing heat and electricity supply equipment such as boilers and cogeneration systems using thinning materials to public facilities, we considered a method of utilizing biomass energy while promoting thinning. In this research, while establishing the management method of the forest such as the place, the time, the quantity etc. where thinning should be performed, the economic efficiency and environmental property in case of introducing the biomass equipment are evaluated, and the optimum equipment configuration and operation method are found.
