Constellium sorts automotive aluminum scrap with LIBS technology

Constellium (CSTM) announced a major advancement in aluminium recycling for the automotive industry, by implementing Laser-Induced Breakdown Spectroscopy technology at an industrial scale. This initiative, developed in collaboration with OSR GmbH & Co. KG, a German recycling specialist, and a premium European automotive manufacturer, marks a significant step in reducing carbon emissions in the automotive supply chain by increasing the use of recycled aluminium. One of the most significant challenges in automotive aluminium recycling is the proper segregation of alloy families, which are critical to maintaining material quality. Traditionally, mixed 5xxx and 6xxx alloys from stamping scrap were downcycled, limiting their use in high-value applications. LIBS sorting technology enables rapid and accurate sorting of aluminium scrap, achieving over 95% purity for both alloy families. Constellium has already processed significant volumes of LIBS-sorted scrap at its Neuf-Brisach plant in France, recycling it into high-quality aluminium solutions without compromising material integrity. This success showcases the industrial viability of LIBS sorting and its potential to transform aluminium recycling practices on a global scale.
