Mercedes-Benz opened Europe's first battery recycling plant with an integrated mechanical-hydrometallurgical process making it the first car manufacturer worldwide to close the battery recycling loop with its own in-house facility.

The recycling plant in Kuppenheim, southern Germany, creates a genuine circular economy. This underpins the pioneering spirit and innovative strength of Mercedes-Benz as it strives to significantly reduce the consumption of valuable primary resources. Unlike existing established processes, the expected recovery rate of the mechanical-hydrometallurgical recycling plant is more than 96 percent. Valuable and scarce raw materials such as lithium, nickel and cobalt can be recovered – in a way which is suitable for use in new batteries for future all-electric Mercedes-Benz vehicles. The company has invested tens of millions of euros in the construction of the new battery recycling plant and thus in the value creation in Germany.

Mercedes-Benz has set itself the goal of building the most desirable cars in a sustainable way. As a pioneer in automotive engineering, Europe's first integrated mechanical-hydrometallurgical battery recycling factory marks a key milestone towards enhancing raw-materials sustainability. Together with our partners from industry and science, we are sending a strong signal of innovative strength for sustainable electric mobility and value creation in Germany and Europe.

The future of the automobile is electric, and batteries are an essential component of this. To produce batteries in a resource-conserving and sustainable way, recycling is also key. The circular economy is a growth engine and, at the same time, an essential building block for achieving our climate targets! I congratulate Mercedes-Benz for its courage and foresight shown by this investment in Kuppenheim. Germany remains a cutting-edge market for new and innovative technologies.

Mercedes-Benz’s technology partner for the battery recycling factory is Primobius, a joint venture between German plant and mechanical engineering company SMS group and Australian process technology developer Neometals. The plant is receiving funding from the German Federal Ministry for Economic Affairs and Climate Action as part of a scientific research project with three German universities. The project looks at the entire process chain for recycling, including logistics and reintegration concepts. The partners are thus making an important contribution to future scaling of the battery recycling industry in Germany.

For the first time in Europe, the Mercedes-Benz battery recycling plant covers all steps from shredding battery modules to drying and processing active battery materials. The mechanical process sorts and separates plastics, copper, aluminium and iron in a complex, multi-stage process. The downstream hydrometallurgical process is dedicated to the so-called black mass. These are the active materials that make up the electrodes of the battery cells. The valuable metals cobalt, nickel and lithium are extracted individually in a multi-stage chemical process. These recyclates are of battery quality and therefore suitable for use in the production of new battery cells.

Mercedes-Benz takes a holistic approach to the circularity of battery systems and considers three core topics: circular design, value retention and closing the material loop. With its Design for Circularity approach, the company takes the entire battery technology value chain into account from the outset. At the Mercedes-Benz eCampus in Stuttgart-Untertürkheim, which opened in 2024, circular thinking flows into the development of new battery cells.
