Constellium has announced its agreement with Renault Group to establish a closed-loop recycling process for the all-new Megane E-TECH Electric.

Aluminium, lightweight and fully recyclable, is the material of choice for the electrification of the automotive fleet.

Renault Group has developed a closed-loop recycling process to bring manufacturing scrap from the stamping process directly back to Constellium, resulting in a reduced CO2 footprint. Based on best practices to avoid mixing 5xxx and 6xxx alloys and to compact scrap for optimal logistics at Renault Group, the closed-loop process will recycle these alloys, so that they can be reused in Renault Group’s production without any loss of properties, and overall with no downcycling.

For the all-new Megane E-TECH Electric, Constellium supplies the aluminium Auto Body Sheet for outer panels from its Surfalex® product range, combining high strength with excellent surface quality and hemming properties, and for the inner panels from the forming optimised Formalex® product range.

“We are very excited to continue to collaborate with Renault Group on sustainable and efficient aluminium solutions. Together we will contribute to the circular economy within the automotive industry, while also helping both companies to meet their individual sustainability targets,” said Hervé Ribes, Director, Technical Customer Service Automotive for Constellium’s Packaging & Automotive Rolled Products business unit. “Further, converting R&D expertise to full-scale industrialization is in the DNA of Constellium. This successful collaboration between Renault Group and Constellium proves that it is working.”

“We are delighted to expand these activities with Constellium as part of our journey to carbon neutrality, commented Yvan Chastel, Expert Leader for Metals and Processes at Renault Group. “The closed-loop recycling we had first established for the former vehicles manufactured in Douai are now further optimized for the production volumes of the all-new Megane E-TECH Electric. This collaboration further demonstrates our capacity to be at the forefront of decarbonizing mobility by reducing CO2 emissions throughout the life cycle of our vehicles.”

Since 2021, Constellium and Renault Group have been working jointly on R&D projects for alloys and solutions that enable closed-loop recycling, such as in the ISA3 collaborative initiative with ESI Group, Institut de Soudure (Welding Institute), and the University of Lorraine.
