  • Description: In the article, the possibility of highly profitable and environmentally safe processing of low-quality wood and wood waste by low-tonnage plants using extrusion technology has been substantiated. The basics of the technology for the production of extrusive thermomechanical wood pulp (ETMP) with the use of chemicals are given, and the main specific costs of wood, chemicals and energy resources are provided. The limits of the main quality indicators of ETMP are provided, which are important for its widespread use in the production of paper and cardboard. The extrusive technology for processing of raw materials into fiber is economically viable. The target product is obtained from wood with a yield of 85–80%, and from straw, of 75–60% of the mass of raw materials; profitability is in the range of 25–50%; production creation time is 1.0–2.5 years, depending on productivity (20, 50, 100 and 200 tons per day), and the return on investment is 2-3 years. The advantages of technological lines for processing wood and straw are compactness, ease of installation, and relatively small production areas. The extrusion technology is promising for the processing of waste from forestry enterprises, and is recommended for use in Russia.
