The paper considers the formation of composites based on mixtures of powders of highly dispersed polyethylene, polystyrene, natural silk and wool, cellulose, which have good physical and mechanical properties and are suitable for using materials with desired properties. The paper also provides information about composites, the principles of creating polymer composite materials. The main technological methods for obtaining composite materials and methods for molding products based on them are given. It contains data on the features of the structure and properties of the obtained polymer composites: particulate-filled, fiberreinforced, polymer mixtures. The study's findings also show that the creation of new technological procedures will enable the optimization of waste's resource potential, the reduction of waste sent for disposal to lessen waste's detrimental effects on the environment, and the expansion of the range of materials available for use in household, technical, and special applications. The parameters of the greatest technologies currently in use are suggested, together with technological, technical, and administrative solutions for waste processing.
