Abstract. New paradigms based on Circular Economy (CE) principles are needed for boosting the ecological transition and improving the energy and material efficiency. In this paper, a novel remanufacturing process chain for End-of-Life (EoL) automotive panels is first presented. The core of the recycling strategy is the reshaping of curved EoL automotive sheets through flattening by means of a hydraulic press. Flattening experiments together with press power consumption measurements have been performed on thin steel parts. While the experimental procedure demonstrated the technical feasibility of flattening “small-scale” steel parts, a more complete analysis on environmental sustainability was required. For this purpose, a Life Cycle Assessment (LCA) of the remanufacturing process chain proposed was set up. The results of the study demonstrated that flattening is a viable solution for reshaping EoL automotive panels, and that, for one kg of reshaped steel, approximately 2.2 kg CO2 and 24 MJ could be saved.
