Abstract
This article analyzes modern methods of recycling ash and slag waste generated by coal combustion in thermal power plants, as well as their impact on the environment. Currently, the problem of industrial and household waste is becoming increasingly urgent, with ash and slag waste being among the largest in terms of volume. These waste materials pose a risk of environmental contamination with toxic substances and heavy metals. Dust is generated in areas affected by ash dumps, and the components of the ash are washed away, leading to their infiltration into the soil and groundwater, which worsens the ecological situation. This, in turn, negatively affects plants and human health. Recycling ash and slag waste helps conserve natural resources and address ecological issues. The study conducted an analysis of the ash and slag waste from «Kentau Service» TPP-5, determining their potential for use as an ecological construction material — brick. Additionally, the physical and chemical suitability of these waste materials for brick production was tested. It was proven that recycling TPP waste is both economically and ecologically efficient.
