Optimization of recycling strategy for solid industrial waste

The rational and efficient use of natural resources is an important element for sustainable development. Waste is significant loss of material and energy resources. Recycling and disposal of the generating waste can cause the environmental pollution and human exposure to harmful substances and infectious organisms. The waste generation indicator is closely related to the level of economic activity in the country and reflects the structures of production and consumption formed in the society. The reduction in waste generation is an indicator of the progress of economic sectors towards less material-intensive structures of production and consumption. Plant origin waste is mainly generated in the lumber industry and it is a large-scale source of environmental pollution. The constant generation and accumulation of these wastes is a serious environmental problem. The main reason for the current state is the insufficient capacity for timber processing. It aggravates the problem of the integrated use of low-grade, small-scale wood and wood waste. As a result, the main competitive products in the forest complex of the Krasnoyarsk Region are currently lumber and round wood. The solution to the current problem concerning the optimal use of waste generated on the territory of the Krasnoyarsk Region must be solved with the help of mathematical modeling and optimization of the recycling process of lump plant waste. The rational use of lump plant waste is one of the most serious and unsolved problems.
