Abstract
Past research has been reviewed, mainly on eco-town projects and circulation of regional resources to design a new concept for the development of Regional Circular and Ecological Sphere (R-CES) from the point of material cycle and waste management. Regions where the movement has been accelerating since the 2020’s will require an integrated approach for creating action plans and goals, together with scenario setting addressing zero carbon cities. In order to realize a R-CES, effective regional activities and technologies for cyclical use of community resources must first be determined. Following this, the effects, with the determined critical indexes such as GHG emissions and economic balance of the region, must be determined. An agriculture, forestry, and fisheries linkage model is seen to be a possible core approach for its application in many areas of Japan. Methane fermentation and composting are important core processes in such a model. Referencing good case studies on bio-based material cycles, these concepts are expected to be adopted in each community that aims for R-CES. This article details a case study in the Kyoto region.
