TECHNOLOGICAL AND ENVIRONMENTAL ASPECTS OF PRODUCING COMPOSITES BASED ON RECYCLED POLYMERS

This article examines the technological and environmental aspects of producing composite materials based on recycled polymers. The relevance of the study is обусловлена the need for rational utilization of polymer waste and reduction of its negative environmental impact. The paper analyzes modern approaches to the recycling of secondary thermoplastics (polyethylene and polypropylene) and investigates the influence of fillers of various nature on the physical and mechanical properties of composites. Experimental results showed that the introduction of mineral and organic fillers contributes to an increase in strength characteristics and elastic modulus; however, it is accompanied by a decrease in material ductility. Optimal technological processing parameters ensuring uniform distribution of components and minimization of degradation processes have been determined. The conducted environmental analysis confirmed that the use of recycled polymers significantly reduces energy consumption and greenhouse gas emissions compared to conventional technologies. The obtained results demonstrate the перспективность of using composites based on recycled raw materials in various industrial sectors.
