A tense situation is emerging in Uzbekistan regarding the supply of high-quality natural raw materials to the gypsum production industry. Consequently, many industrial man-made wastes containing gypsum compounds are disposed of in landfills. These wastes, which are harmful to the environment, are valuable raw materials that can be used in the production of gypsum binders in many cases. The use of man-made waste in the production allows to achieve great economic efficiency in the production of gypsum binders and various construction materials and products based on two important problems -prevention of environmental pollution. The article describes the results of scientific research on obtaining gypsum binders from waste molds used in ceramic industry enterprises producing porcelain and sanitary-technical products. Waste molds of “EKOKERAMA” LLC (Fergana city, Uzbekistan) were used in the research. Waste mold pieces were treated with isothermal heat under “thermal shock” conditions. Due to the increase in the amount of α-modification of gypsum in the resulting product, gypsum binders whose physical and mechanical properties meet the requirements of GOST 23789-2018 were obtained.
