00:00The Mercedes-Benz battery recycling plant in Kuppenheim combines mechanical and hydrometallurgical
00:07recycling processes at one location.
00:10This makes it unique in Europe on this industrial scale.
00:15After checking the state of charge, the process starts with placing the battery modules on
00:20a conveyor belt.
00:22The batteries are then mechanically crushed, washed, and separated into coarse and fine
00:27fraction.
00:30Using gravity-based air systems, magnetic separators, a grinder, and various sieves
00:35– plastics, copper, aluminum, and iron – are separated and packaged according to type.
00:42At the same time, the black mass contained in the dried coarse material is separated.
00:48The previously separated fine fraction contains the largest proportion of black mass.
00:54This is filtered and further processed together with the mass from the coarse material in
00:59the hydrometallurgy.
01:00Here, the metals are first dissolved into a liquid solution by leaching.
01:06The undissolved graphite is separated using filters and then packaged.
01:11The precipitated iron and the aluminum components are treated in the same way.
01:16The valuable raw materials such as copper, cobalt, manganese, nickel, and lithium are
01:21recovered one after the other in a multi-stage chemical separation process.
01:27Cobalt and nickel are then crystallized.
01:30The battery recycling plant has an annual capacity of 2,500 tons.
01:36The recovered materials are fed back into the material cycle and are used in the production
01:41of more than 50,000 battery modules for new all-electric Mercedes-Benz models.
01:48This closes the raw material loop.
