Audi also uses aluminum for its battery housings. This light metal is obtained from bauxite in a process that is very energy-intensive. In order to save resources and energy, Audi has launched the Aluminium Closed Loop project, in which offcuts are returned to suppliers and recycled. In 2018 alone, some 70,000 metric tons of CO₂-equivalent emissions were saved this way. Audi is the first car manufacturer to be awarded the Aluminium Stewardship Initiative (ASI) sustainability certificate for the sustainable production of battery housings.
These are just a few areas where Audi is focusing on sustainability in order to close material loops as part of a circular economy. And they show that it is possible.
