This research investigates the environmental performance of two products obtained using slag derived from copper primary production (copper slags, CS). The first is a tile produced as a traditional stoneware ceramic plate (CS tile) and the second product is a glass-ceramic sample obtained by melt quenching method (CS bulk sample). The products are intended for use in industrial plants as auxiliary heating elements aimed at absorbing microwave. Methods The environmental assessment was carried out using LCA methodology and the obtained outcomes were compared to the results calculated for a traditional tile containing silicon carbide (SiC tile). Results The analyses show that the innovative products have an environmental load of 74% for the CS tile and 54% for the CS bulk sample lower than the environmental impact calculated for the traditional SiC-based material tile. The latter presents a high environmental load due to the incidence on the total impact of the raw materials production. In fact, LCA analysis proves that copper slags production has an impact of 96% lower with respect the SiC production. Conclusions This study identifies a possible waste reduction strategy in accordance with the European end-of-waste criteria, but these results should be supported by a site analysis in order to provide an appropriate context for decision making.
