[0002] Waste paper treatment is the process of reprocessing recycled waste paper to obtain qualified fibers for the production of paper products. The recycling and utilization of waste paper is beneficial to protecting the environment, protecting forests and saving resources. Waste paper can be reused many times. Pulp is a fibrous material made from plant fibers through different processing methods. It can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp according to the processing method; it can also be divided into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp and rag pulp according to the fiber raw materials used; it can also be divided into refined pulp, bleached pulp, unbleached pulp, high-yield pulp and semi-chemical pulp according to different purities. It is generally used to make paper and paperboard. In addition to being used to make special paper, refined pulp is also often used as a raw material for making cellulose derivatives such as cellulose esters and cellulose ethers.
