The object of research is fly ash as part of ash and slag waste generated due to the production activities of thermal power plants, CHP. This work aims to systematize data on the volumes of fly ash generated as part of ash and slag waste, disposal methods, and a review of the world's experience in using fly ash to produce building materials. Research methods: overview literature sources, annual reports of energy companies, generalization, identification of potential uses of ash and slag, and the main obstacles. Results. The analysis of the Russian experience of industrial waste management shows the growing interest of the state and businesses in waste management methods. At the same time, the increase in processing volumes is limited by several regulatory, technical, and economic barriers. While studying scientific papers, it can be concluded that research mainly aims to improve the physical and chemical characteristics of materials using fly ash. With the complex use of ash and slag waste as secondary resources and the production of building materials, it is necessary to consider the different compositions of ash dumps.
