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.

北海道寒冷地区有大量速生桦树，也有疏林、农业废弃物等劣质生物质材料，但利用效率较低或被丢弃。我们在北海道进行了一项基础调查，以建立一个新的生物质转化工厂，将其生物质材料转化为绿色化学品，精细化学品，生物降解塑料，生物能源等。建立了两种无污染节能的生物质精炼工艺。一种是常压醋酸法，另一种是HBS法。桦木和其他生物材料很容易分解成纤维素、木质素和/或半纤维素，产量几乎是定量的。所得纤维素具有优良的造纸、溶解纸浆和生化性能。从前者得到的单糖半纤维素可用于生物化工和食品添加剂。木质素可用于清洁和高热值的生物燃料、功能性生物聚合物（环氧化物、酚醛-间苯二酚和可能的聚氨酯树脂）、成型活性炭等。以桦树外树皮为原料，用乙酸等溶剂提取白桦素，收率为30%。桦木素可作为精细化学品、生物降解聚合物和抗hiz剂等药物的原料。
