The usual processes are crushing, cooking, washing, screening, bleaching, purification and drying of plant fiber materials.How to Make Pulp

2. A new modern biological pulping method was developed. Special strains (white rot fungus, brown rot fungus and soft rot fungus) were used to decompose the lignin structure, and the rest of the cellulose solution was bleached by mechanical or chemical methods. In this process, most organisms decompose and open lignin. Chemical methods are only used as an auxiliary role.How to Make Pulp

     Compared with traditional methods, they are rarely used in chemical products, so you can discharge or discharge less liquid waste. It is an environmentally friendly and clean pulping method.How to Make Pulp
