Today in Russia there is an acute problem of processing of waste of the logging and wood processing industry. At almost all stages of timber production, waste is generated, which is disposed of or left to rot. Felling residues obtained in the process of cutting operations are used least of all. Currently, loggers leave up to 30 % of only the stem of trees, primarily low-quality wood, not to mention twigs, conifers, stumps, while logging waste is a valuable raw material that can and should be used for further processing. The article discusses the prospects for the development of the timber industry, including related to the rational use of wood resources. A number of experiments were carried out in order to determine the influence of design and technological parameters of knife equipment on the quality indicators of wood-fiber semi-finished product.
