The paper presents the results of studying the influence of the concentration of thermoash from household waste on the main physical-mechanical properties of composites based on polypropylene. Properties such as ultimate tensile stress, tensile yield strength, flexural strength, elongation at break, heat resistance and melt flow index were studied. We used thermoash of various dispersity: 75–110 nm, 300–500 nm, 1200–2000 nm. The results of studying the regularity of changes in properties depending on the concentration and fineness of thermoash showed the advantage of nanocomposites. The loading of a compatibilizer into the composition of composites contributed to a significant improvement in strength characteristics
