“Biomass utilization and carbon cycle / carbon recycling”

The growth of biomass, due to the fixation of CO₂, is an important component in the carbon cycle. On the other hand, carbon recycling is a mechanism to reduce CO₂ emissions into the atmosphere by reusing separated and recovered CO₂ as organic substances, i.e., chemical feedstock and fuels. It can be the cyclical use of carbon within human society. In this presentation, the biomass utilization is discussed from the viewpoints of carbon cycle and carbon recycling, respectively.

“Nanocellulose applicable from materials to energy”

Nanocellulose produced from plants such as wood is ultrafine fibers with a width of 100 nm or less. Nanocellulose has high physical properties such as high strength, high elasticity, and special viscosity, and the development of high-performance materials by compounding with resins, rubbers, etc. is being vigorously pursued by utilizing these characteristics. In addition, it has a large surface area, high reactivity and adsorption of substances, and high enzymatic saccharification. This characteristic is also effective as a pretreatment in bioethanol production.
