Research Abstract

There are a large quantity of birch tree fast-growing in a cold district, and also poor-grade biomass materials such as thinning and agricultural wastes in Hokkaido, but they have been utilized less effective use or discarded. We carried out a fundamental investigation to establish a novel biomass-conversion mill in Hokkaido to convert their biomass materials to green chemicals, fine chemicals, biodegradation plastics, bioenergy and so forth.
We established two biomass refinery processes with non-pollution and save-energy. One is an atmospheric acetic acid method and another HBS method. Birch wood and other biomas materials were easily fractionated into cellulose, lignin and/or hemicellulose in almost quantitative yields. The resulting cellulose had excellent properties for paper and dissolving pulps, and biochemicals. Hemicellulose obtained as monosaccharides from the former can be used for biochemicals and food additives. Lignin can be utilized for biofuel with clean and high calorific value, and functional biopolymers (epoxide, phenol-resorcinol and maybe polyurethane resins), molding active carbons and so forth.
Betulin was extracted with acetic acid and other solvents in a yield of 30% from outer bark of birch. Betulin appears to be used as raw materials for fine chemicals, biodegradation polymers, and medicine such as anti-HIZ agents.
