Rational and efficient use of natural resources is an important element of sustainable development. Waste is a significant loss of material and energy resources. Recycling and disposal of waste can be a cause of pollution, harmful substances and infections on people. Index of waste production is closely linked to the level of economic activity in the country and sums up the structures of production and consumption that are formed in the society. Reduction of capacity size of waste production is a measure of promotion of the economy sector to less material-intensive structures of production and consumption. Phytogenic wastes are mostly formed in the timber industry, and also are pollutant source of environment. Continuing production and accumulation of waste is a serious environmental problem. The main reason for these circumstances involves insufficiency of power in added-value wood processing, that increase the problem of integrated utilization of low-grade wood, small wood and demolition wood. As a result, the main competitive products in the timber complex of the Krasnoyarsk Territory are industrial wood and roundwood. Solution to these topical issues of optimum use of the resulting waste in the Krasnoyarsk Territory needs to be solved with the help of mathematical modeling of process optimization of recycling lumpy plant waste. Rational use of lump plant waste is one of the most serious and, unfortunately, unresolved problem
