StockachAlu has achieved both ASI Performance Standard and ASI Chain of Custody certification for its remelting/refining and casting operations in Stockach, Germany. The facility’s main outputs are rolling slabs made from recycled scrap.

Aluminium Stewardship Initiative (ASI) today announced that StockachAlu has been successfully certified against the ASI Performance Standard for responsible production, sourcing and stewardship of aluminium. The facility’s main processes include remelting of scrap aluminium, including heavily contaminated scrap and dross and casting into rolling slabs. The facility has an annual capacity of 70000 tonnes.

The ASI Certification program was developed through an extensive multi-stakeholder consultation process and is the only comprehensive voluntary sustainability standard initiative for the aluminium value chain. The ASI Performance Standard defines environmental, social and governance principles and criteria, with the aim to address sustainability issues in the aluminium value chain. It sets out 59 criteria under the three sustainability pillars of Governance, Environment and Social, which address key issues such as biodiversity, Indigenous Peoples rights, and greenhouse gas emissions. The ASI CoC Standard sets out requirements for the creation of a Chain of Custody for material that is produced and processed through the value chain into diverse downstream sectors. The implementation of ASI’s CoC Standard links verified practices at successive steps of the supply chain – certified under the ASI Performance Standard – to the products produced by ASI Certified Entities.

The independent, third-party audits of the StockachAlu facility was carried out by GUTcert (AFNOR Group).

Fiona Solomon, Chief Executive Officer at ASI said, “ASI congratulates StockachAlu on their Performance Standard and Chain of Custody certifications at their remelting and casting operations. The facility’s ability to recycle not only contaminated scrap, but also dross, into new aluminium rolling slabs shows both the sustainability potential of this metal and the important role the company plays in the implementation of a circular economy. Their dual ASI certification demonstrates that the company is committed to undertaking this production in a responsible manner.”

We are proud to receive full ASI certifications for both Performance Standard as well as Chain of Custody Standard as this an important milestone for our company. Our high quality rolling slabs are 95% based on recycling material and therefore sustainability is at the very core of our business model. I would like to thank our team for the good work and dedication demonstrated in achieving this certification,” said Markus Wild, Managing Director of StockachAlu.
