EN Nowadays, the increasing number of vehicles is contributing to an increase in the amount of polymer materials in the overall waste stream after the end of their life cycle. Therefore, it is important to appropriately carry out the process of recycling, separation, and reuse of these materials to protect the environment and minimize the utilization of natural resources. These factors are in accordance with the circular economy model and the concept of sustainable development. Implementing these principles enables us to minimize natural resource consumption and reduce our negative environmental impact. By using a circular economy, we can optimize resource utilization and minimize waste generation. The implementation of these factors is essential in achieving a more sustainable and balanced approach to economic growth and environmental protection. The article presents the possibilities of processing polymer waste from the automotive industry to obtain composites with advantageous mechanical properties and structure. To optimize the technology of producing composites, two versions of technological solutions were used, for which standardized test samples were prepared for evaluating the quality of the produced polymer blends. The mechanical properties of the obtained composites, such as tensile modulus, tensile strength, and tensile at break, were evaluated in a static tensile test. Microscopic analysis of the surface structure of the fractures of the composites was also performed. Based on the obtained research results, it was concluded that the most beneficial mechanical characteristics are attributed to composites produced using the mixing technology with the application of a dispersing system of the roller type.
