ASI certifies American Buffalo Metals against Performance Standard V3.1

30 March 2026

American Buffalo Metals has achieved ASI Performance Standard V3.1 (2023) for the sorting, cleaning, charging/melting, tapping, laboratory testing, final inspection, and shipment of A356 aluminium and its alloys produced at their facility located in Crossville, Alabama, USA.

Aluminium Stewardship Initiative (ASI) today announced that American Buffalo Metals has been certified against the ASI Performance Standard V3.1 (2023). The facility operates as a secondary aluminium foundry producing secondary A356 aluminium in sow and ingot form using recycled aluminium feedstock, with production of approximately 20,100 metric tonnes in 2025 and recycled material accounting for around 99% of total output. Production processes include scrap receipt and handling, remelting, refining, casting, and finished product storage.

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 V3 and ASI CoC Standard V2 were launched in May 2022 following a multi-year revision process. The ASI Performance Standard V3 defines 11 principles and 62 criteria under three sustainability pillars – Environment, Social, and Governance – with the aim to address pressing sustainability issues in the aluminium value chain, such as biodiversity, Indigenous Peoples rights, circularity, and greenhouse gas emissions. The 2022 Standards and related documents underwent a minor update in 2023, accounting for editorial changes, correction of minor errors and for general clarification, culminating in the release of Performance Standard V3.1 (2023) and Chain of Custody Standard V2.1 (2023).

The independent, third-party audit of American Buffalo Metals was carried out by DNV Business Assurance Services UK Ltd. A full listing of audit findings is available in the summary audit reports, linked below. One minor non-conformance was identified during the audit under the Criterion 5.3b-e GHG Emissions Reduction Plans – Targets, review and disclosure. American Buffalo Metals will be implementing corrective actions, to be verified in a follow-up audit.
