Constellium SE announced a major advancement in aluminium recycling for the automotive industry by implementing Laser-Induced Breakdown Spectroscopy (LIBS) 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 per cent 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.
“Recycling aluminium scrap with the precision and scale offered by LIBS technology is an unprecedented leap forward for the industry,” said Dieter Höll, Vice President of Global Automotive at Constellium. “This innovative approach allows us to recover high-quality alloys from pre-consumer scrap, significantly reducing our carbon footprint and supporting our customers' sustainability goals.”
Constellium and OSR GmbH & Co. KG will continue to work on enhancements to the technology with the longer-term goal of extracting high-value aluminium from end-of-life vehicles. This initiative aims to create a truly circular system for automotive aluminium, aligning with the industry's shift toward a low-carbon economy.
Constellium, a full-service supplier of rolled and extruded aluminium solutions for the global automotive market, supplies aluminium products for 1 in 4 vehicles produced in Europe and the U.S. We help automakers produce lighter, safer, and more efficient vehicles and collaborate on recycling programs and research projects to advance decarbonization in the industry.
