With the wide application of polyurethane foam, large amounts of polyurethane wastes are generated. Polyurethane waste from vehicles, waste of electrical and electronic equipment and many other sources attracted great attention worldwide as a result of rapidly rising amounts and increasingly tight legislation on its treatment and disposal. Polyurethane waste is recycled in two primary ways. Mechanical recycling, called powdering or recycling of regrind, involves grinding of waste containing polyurethane, and one of the fractions obtained is polyurethane powder. Thus obtained powder is mixed with virgin polymer materials and it can be used for new products. Chemical recycling takes the material back to its various chemical constituents. In this article polyurethane waste from electrical and electronic equipment is used as filers in virgin rubber. Different amount of polyurethane powder was added to rubber blend and their influence on mechanical properties and structure of rubber blends were examined. This study determined the optimal share of powder, in which there is no significant decrease in the properties of rubber compounds.
