Trimet France has achieved ASI Performance Standard Certification for the development, manufacture and sale of aluminium in the form of wire rods, slabs and ingots, production of molten aluminium, and manufacture of anodes at the Saint- Jean-de-Maurienne and Castelsarrasin sites in France. Trimet France is one of only two primary aluminium producers in France.

Aluminium Stewardship Initiative (ASI) today announced that Trimet France has been successfully certified against ASI Performance Standard for responsible production, sourcing and stewardship of aluminium. The wire rods, slabs and ingots cast from primary aluminium at the Castelsarrasin and Saint-Jean-de-Maurienne plants primarily supply the energy, transport, construction, and packaging industries. The combined total annual production capacity of the plants is around 150,000 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 Environment, Social and Governance (ESG), which address key issues like biodiversity, Indigenous Peoples rights, labour rights and safety, gender, and greenhouse gas emissions.

The independent, third-party audit of the Trimet France facilities was carried out by Dekra Certification.

Fiona Solomon, Chief Executive Officer at ASI said, “ASI congratulates Trimet France on achieving Performance Standard Certification. These plants’ aluminium products make vehicles and planes lighter and more economical, wind turbines and electrical installations more efficient, and buildings and packaging more environmentally friendly. ASI Performance Standard Certification demonstrates the company’s commitment to implementing industry-leading ESG criteria in their production processes.”

“The certification of our production plants in France in accordance with the strict ASI requirements confirms our efforts to further develop sustainably produced materials,” says Philipp Schlüter, Chairman of the Executive Board of Trimet Aluminium SE and President of Trimet France SAS. “Sustainability is a key factor in determining our ability to compete. As a manufacturer of aluminium with a low carbon footprint, we are enabling climate-friendly products, securing the future of our sites and contributing to global climate protection goals.”
