Introduction

Because biomass including woods and herbs is renewable carbon resource, its utilization is required for establishing a circular community. As is well known that plant cell wall is mainly composed of cellulose, hemicellulose and lignin, biomass is generally in the state of mixture. For this reason, separation of biomass as a pre-treatment enables the further advanced utilization of its components. I have worked on technique of biomass separation based on chemical engineering, and developed a new method using mixture of water and organic solvent.
In Tokachi, livestock and dairy industries are prospering, and methane fermentation process is focused for the treatment of livestock excrement. Because the digestate, which is obtained the same amount of input quantity, includes fertilizer components such as nitrogen and phosphate, it is sprinkled over lands as a liquid fertilizer. I have also worked on optimal process for utilization of the digestate toward establishing a system rooted in this community.
