Abstract
The “Regional Circular and Ecological Sphere” takes advantage of the SDGs’ concept of integrated solutions to numerous concerns, complementing and supporting resources based on the region’s features while maximizing the utilization of local resources. This research makes a comprehensive evaluation of the three aspects of the environment, economy, and society. First, formulate the evaluation indicators of the regional circulation symbiosis zone. Then, choose the cutting conditions of trees according to geographical factors, use the thinning forecasting system and forest GIS data to evaluate the supply potential of thinned wood in the area, and calculate the heat and power generation of wood biomass. According to the above analysis and calculation, 12,000 tons of unused wood chips can be supplied per year for 36 years from 2016 to 2051. From the economic point of view, the purchase of wood chips of 146 million yen due to the local circulation of wood fuel is expected to save about 50 million yen in intermediate input. And it is estimated that if 12,000 tons of unused wood chips can be supplied in the city per year, and about 98.4 million yen can be saved annually. Finally, from a social perspective point of view, biomass power generation of unused thinned timber using materials worth about 146 million yen is expected to create about 20 jobs.

The “Regional CES” is one of the main initiatives of Japan’s “Fifth Environmental Basic Plan,” which was approved by the Cabinet in 2018, and each area uses its unique qualities to leverage its strengths
The purpose of this study is to estimate the availability of woody biomass in Kitakyushu City and to make a comprehensive evaluation from the three aspects of environment, economy, and society
In addition to the concept of the regional circulation symbiotic area, the evaluation index was set based on the evaluation index of Sustainable Development Goals (SDGs)
Summary
The “Regional CES” is one of the main initiatives of Japan’s “Fifth Environmental Basic Plan,” which was approved by the Cabinet in 2018, and each area uses its unique qualities to leverage its strengths It entails establishing a larger network by establishing a self-sustaining and decentralized community in which resources circulate while coexisting and communicating with neighboring areas. Attempts to accomplish the United Nations Sustainable Development Goals (SDGs) are widely recognized as significant, but biomass consumption has the potential to affect the environment and many other fields. It needs to be considered as a goal to be considered.
