Alcoa Corp is supplying low- and zero-carbon aluminium for the wheels on carmaker Audi's e-tron GT, which will make it the first vehicle to use metal from its Elysis joint venture.
The wheels are being manufactured by Ronal Group using a combination of Alcoa's low-carbon aluminium, EcoLum, and metal produced using the Elysis zero-carbon emissions smelting technology.
Elysis - a joint venture between the United States aluminium producer and Rio Tinto, and backed by Apple and the governments of Canada and Quebec -
uses zero-carbon technology to replace the carbon anode with an advanced conductive material, so it releases oxygen instead of carbon dioxide.
Alcoa's low-carbon EcoLum aluminium is produced with less than four tonnes of CO2 emissions per tonne of metal produced. This incorporates both direct and indirect emissions across the entire production chain, including bauxite mining and alumina refining.
The wheels are produced in Landau, Germany by H??rkingen, Switzerland-headquartered...
