NON-WOODEN RAW AS A SOURCE OF CELLULOSE FIBERS. USE PROSPECTS, PROBLEMS AND SOLUTIONS (REVIEW)

The article discusses various non-wood plants as sources of fibrous raw materials for the pulp and paper industry. The authors cite the main categories of non-wood fibrous raw materials: agricultural waste, naturally growing plants and industrial crops. Information is provided on the position of fibers in the plant: fibers of the inner part of the stem, bast (outer part of the stem) fibers, leaf fibers and fruit fibers, as well as methods for their isolation. Of the variety of non-wood plants, the authors highlight industrial hemp as the most promising raw material, having strong fibers and a high cellulose content. The use of non-timber raw materials has been found to help reduce pressure on forest resources and improve the environmental sustainability of pulp and paper production. Technological aspects of the production of paper products from non-wood raw materials are also considered. The advantages and disadvantages of using alternative raw materials, as well as its prospects, are given. The need for further research and development of new methods and technologies to optimize the efficiency of using non-wood raw materials in the pulp and paper industry is pointed out. In conclusion, a conclusion is drawn about the importance of using non-wood raw materials to reduce the negative impact of paper production on the environment and ensure the sustainable development of this industry.
