The article is devoted to research in the development of composite materials based on polyvinyl chloride and industrial waste from the metallurgical, energy and mining industries. The properties of dispersed waste have been studied, which make it possible to speak of the possibility of their use as fillers for polymer compositions. A comparative analysis of the tested physical and mechanical properties is carried out, depending on the characteristics of the particle size of the fillers. It was revealed that from the point of view of construction materials, all the wastes under study can be used as fillers. The development will make it possible to dispose of industrial waste to obtain useful products and save natural non-metallic materials used in the creation of composites.
