O-30　秋田県の森林簿を用いた持続可能な木質バイオマスのポテンシャル推計及びサプライチェーン構築

抄録

This study aims to estimates the amount of sustainable woody biomass available using a forest inventory and geographic information system. It is investigated that the impact of different transportation routes and power generation methods on the amount of electricity generated through scenario analysis. As a result, the amount available was much smaller, about one-tenth of Akita Prefecture's material production. This may be due to the fact that subsidies for forestry projects such as afforestation and thinning were not taken into account, and that cedar planted forests in Akita Prefecture have reached the optimum age for harvesting. Comparing the scenario with the shortest transportation distance and the scenario with the smallest carbon dioxide emissions by using high-capacity trucks even if the transportation distance increases, the former results in a larger reduction in carbon dioxide emissions. Comparing the large scale intensive and small scale decentralized scenarios, the large scale intensive scenario using co-firing resulted in larger reductions in carbon dioxide emissions because of the direct substitution of coal.
