Abstract
The pulp and paper industry is one of the basic branches of the economy, it plays an important role in improving the scientific and technical level of almost all sectors of the economy. The main source of raw materials for this industry is coniferous wood.The huge base of natural resources attracts investments in this industry, stimulates the growth of production. In Russia, an extensive model of forest management is mainly used, i.e. natural forest is being cut down. The difficulty of restoring forest resources in a natural way is that this process takes a lot of time and there are various factors on which the speed of restoration of forest ecosystems depends.
The paper considers a method for obtaining fine-dispersed cellulose from an alternative source of raw materials to wood and factors influencing the development of a fibrous suspension in a disc mill. The value of the degree of polymerization of cellulose that has previously passed the grinding stage, with different degrees of grinding on the Shopper– Rigler scale, is analyzed.
