The article shows the influence of the content of galvanic waste with different chemical composition on the physico-mechanical properties of thermoplastic composite material. In this study, samples of a secondary polypropylene filled with 15 wt.% galvanic waste with high content of iron and chromium were analysed. For a detailed evaluation of the mechanical behavior of filled recycled polypropylene, stress relaxation of the samples was tested in a wide temperature range from 20 to 120 degrees
