摘要：The rational use of wood cannot be imagined without the use of synthetic resins and adhesives, on the basis of which all the main types of wood composite materials are made. The use of synthetic resins provides: production of high-quality glued products with an increased service life due to strength properties; reducing the material consumption of manufactured products and more complete use of low-grade raw materials; improve the fire, bio - and chemical resistance of manufactured materials. Due to the lower consumption of raw materials for the manufacture of glued parts, their cost is usually lower than that of solid wood parts. The international market of adhesives is represented by a wide range, in which 63% are synthetic adhesives. When wood is processed at pulp and paper enterprises, 40-50 million tons of alkaline lignin, 5 million tons of lignosulfonate, 3.5 million tons of technical hydrolytic lignin are produced annually in the world. In the future, the volume of industrial processing of wood will increase by 50-60% and therefore the issue of disposal of such waste is the most important task. Lignins in the form of various large- tonnage wastes are an environmental and technological problem for many chemical industry enterprises and adjacent residential areas.
