The development of the fuel and energy complex of the Irkutsk region has led to the accumulation of a huge amount of ash and slag waste, which can be considered as technogenic raw materials. The development of technology for their effective processing will allow not only to obtain an economic effect, but also to reduce environmental stress in the areas adjacent to thermal power plants. The paper presents the results of the study of physical, chemical and technological characteristics of TPP wastes of the Irkutsk region and possible technologies of their complex processing.
