Substantiation of the choice of pr–iority areas for the use of low-commodity timber from the “SHELON” timber industry complex

The work is devoted to substantiating the choice of priority areas for the use of lowcommodity timber from the “SHELON” timber industry complex – one of the flagships of the timber processing industry in the North-West of the Russian Federation. In the process of logging, a significant amount of low-quality wood is formed at the enterprise in the form of fine grain, balance and technological raw materials, which are currently not being processed efficiently enough. The paper investigates and develops alternative rational directions for the effective processing of low-quality wood raw materials at the enterprises of the “SHELON” timber industry complex. During the research, the task of selecting and substantiating promising areas for processing existing low-quality wood raw materials was solved taking into account the analysis of logistical, technical, technological, environmental, energy, raw materials, economic factors, water resources. The following requirements for potentially manufactured finished products were taken into account: wood should make up the largest share of the finished product; the proposed product should, if possible, be made from all available wood species; the share of ingredients purchased on the side (adhesives, fillers, etc.) should be minimized; products should not be experimental and should have proven market advantages. prospects, possibly low production cost and high marginality; products should have an all-season demand. The following options for processing low-commodity wood are recommended: sawmilling using small-diameter roundwood; production of various building structural materials based on crushed wood and mineral binders; production of thermomechanical mass; production of various types of products based on pyrolysis processes; production of structural slab material (OSB slabs).
