AS Oxidwerke has a processing capacity of around 55,000 tonnes of aluminium salt slag per year, from which more than 20,000 tonnes of salt, 1,000 tonnes of aluminium, and 30,000 tonnes of oxide are recovered annually. The recovered aluminium is then used to make new aluminium products, salt for aluminium melting process, and oxide for construction materials such as cement.
The ASI Performance Standard V3 (2022) was launched in May 2022. The certification defines 11 principles and 62 criteria under three sustainability pillars – Environment, Social, and Governance.
On receiving the certification, Markus Wild, Managing Director of AS Oxidwerke, said: “Recycling of aluminium salt slag is key for the sustainable operation of rotary furnaces. Our recycled aluminium and salt are re-used by our customers’ aluminium recycling operations. Aluminium oxide is an important component of many products in the construction materials industry, and by substituting primary alumina, it makes an important contribution towards reducing carbon footprint. We are delighted that AS Oxidwerke is the first dedicated salt slag recycling company to receive full ASI certification against the performance standard. This shows our commitment to our comprehensive ESG programme.”
Fiona Solomon, Chief Executive Officer at ASI, said: “We warmly congratulate AS Oxidwerke for achieving Performance Standard Certification V3 (2022) at its Stockach facility. Aluminium is known for its circular properties, typically with reference to scrap recycling and its many benefits. Equally important is the recycling of aluminium salt slag done by companies like AS Oxidwerke to keep it from becoming landfill, recover its valuable components and put these back into productive use.”
The independent, third-party audit of the AS Oxidwerke GmbH facility was carried out by GUTcert (AFNOR Group).
In May 2022, ASI welcomed AS Oxidwerke as a new Production and Transformation member.
