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.

The paper presents an analysis of the processes of formation and processing of vegetable waste. An assessment is given to the existing ways of processing woodworking wastes and their inefficiency is justified. A new kind of resource and energy-saving grinding set of disk mills is proposed. On the basis of the analysis of the results of experimental research, the effectiveness of the use of the proposed method for the production of wood fiber is substantiated.

the paper presents the analysis of volumes of waste wood processing industries in the form of sawdust and considers modern directions of their use. It justifies the rationality of production of fibreboard by using a semifinished product obtained from sawdust. The mathematical description of the process of production of wood-fiber plates with the addition of a semifinished product obtained from sawdust as the total weight, thus establishing the quantitative relationship of studied process parameters physico-mechanical parameters of the finished plate.

In accordance with the theory of mathematical and statistical modeling, evaluation studies, selected the main characteristics of the models describing the studied production process of fiberboard using different types of binders. In accordance with the developed plan of the selected controlled studies, uncontrolled and controlled factors of the process under study. The levels, steps, and intervals of variation of the studied factors. As a method of obtaining the mathematical dependencies of the quality indicators of fibreboard from the kind of used binder was enacted active single-factor experiment. The results of the studies conducted statistical analysis of the dependence of physical-mechanical characteristics of the performance of the finished plate thickness fibreboard manufactured by wet and dry methods, interpretation of research results, quantitative and qualitative relationships between the studied parameters.
