Innovative LIBS Sorting Technology Boosts Constellium’s Aluminium Recycling
Paris-based aluminum producer Constellium SE has adopted laser-induced breakdown spectroscopy (LIBS) technology to sort mixed aluminum scrap from the automotive industry, improving the efficiency and purity of recycling. Developed in collaboration with OSR GmbH & Co. KG and a European automaker, this innovation allows for the precise separation of 5000 and 6000 series alloys, achieving over 95% purity. By recycling this scrap into high-quality aluminum, Constellium reduces carbon emissions and supports the automotive industry’s sustainability goals. The company plans to enhance LIBS further and expand its use for recycling end-of-life vehicles. Constellium’s efforts align with similar initiatives by other companies like Novelis and Hydro, who are also exploring advanced sorting technologies to improve aluminum recycling.
