日本利用废旧日本东京片冈纸业公司,新建了利用废旧报纸生产葡萄糖的加工厂。他们先将废纸用酸（如磷酸）充分溶解其中的纤维后，再用酶将其分解成葡萄糖。采用这种先酸溶解后酶分解的方法,可以控制酶的用量。其单价比采用农作物作原料所生产的葡萄糖成本低20—30%。日本利用废 Japan to use scrap Japan’s Tokyo Kataoka paper company, the new use of waste newspaper production of glucose processing plants. They first waste paper acid (such as phosphoric acid) to fully dissolve the fibers, then use enzymes to break it into glucose. Using this method of enzymolysis after acid dissolving, the amount of enzyme can be controlled. Its unit price is 20-30% lower than the cost of glucose produced using crops as raw materials.
