Assessment of the safe use of ash and slag waste from the Krasnokamensk heat and power plant in the Trans-Baikal Territory

The main problem of coal generation is the environmental safety of the industry. The most important factor limiting the operation of coal thermal power plants is the accumulation of ash and slag waste, which is a constant source of environmental pollution. One of the possible solutions to this issue is the composition of ash and slag waste and the development of an effective system for its utilization as secondary raw materials. The purpose of this article is to present the results of comprehensive studies of ash and slag waste from the Krasnokamensk coal thermal power plant in the Trans-Baikal Territory, to assess the quality indicators of ash and slag waste, including safety criteria. Evaluation of the environmental hazard of waste will allow the development of recommendations for choosing the directions of their use, separately for each object of study. The research results are aimed at the environmentally oriented development of the economy of both the Trans-Baikal region and the Russian Federation as a whole. The implementation of the research results will allow the development and substantiation of recommendations for the use of ash and slag waste accumulated at coal-fired power plants in the Trans-Baikal Territory in certain sectors of the region's economic activity, which will reduce the area of land alienation for waste disposal facilities and the environmental burden on territories adjacent to thermal power plants.
