Abstract
Methodological bases of rational use of technogenic raw materials potential are developed. Technogenic processes forming industrial wastes are ranked by the degree of transformation of end products. Depending on the energy content of raw materials (energy provided by natural and technogenic processes) and the energy intensity of operations in the formation of waste, the criteria for assessing the quality and principles of technogenic waste utilization are defined. Approbation of theoretical studies in laboratory conditions confirmed the effectiveness of the proposed approach and allowed to establish the areas of utilization of large-tonnage wastes of mines. Low water demand binders (LWB) and a wide range of construction materials were synthesized on their basis. Regulatory documents allowing to use these wastes in road industry and construction industry have been prepared.
