CURRENT STATE OF THE PROBLEM OF GENERATION, ACCUMULATION, AND UTILIZATION OF ASH AND SLAG WASTE FROM COAL POWER ENGINEERING IN RUSSIA AND THE WORLD

Annotation. The article examines the current state of the problem of generation, accumulation, and utilization of ash and slag waste formed during coal combustion at thermal power plants. It is shown that, with the continuing importance of coal power generation in the global energy sector, the issues of handling fly ash, fuel slag, and ash and slag mixtures continue to be global in nature. Based on an analysis of scientific literature and current statistical materials, approaches to the utilization of ash and slag waste in various countries of the world are considered. Differences between regions in terms of waste generation volumes, the level of their involvement in economic turnover, and priority areas of application are identified. It is shown that in countries with a developed ash and slag management system, the main factors of high utilization are stable demand from the construction industry, developed regulatory framework, and the presence of monitoring institutions. Separate attention is paid to Russian practice: regulatory mechanisms, monitoring systems, and the regional structure of ash and slag waste generation. It has been established that the greatest concentration of ASW on the territory of the Russian Federation is characteristic of Siberia and part of the Far East, which determines the priority of these regions for utilization programs and further involvement of waste as secondary materials.
Keywords: fly ash, slag, utilization, waste, power plants, energy, coal.
