Aluminium Stewardship Initiative (ASI) today announced that Nanjing Yunhai Aluminum Co., Ltd. has been certified against the ASI Performance Standard V3.1 (2023). The facility manufactures high-quality industrial aluminium alloy cast rods, ingots, and extruded profiles for applications including automotive lightweighting, electronics, and consumer uses. Production activities include non-ferrous metal smelting, casting, rolling, and extrusion, supported by three aluminium alloy casting lines, one aluminium alloy ingot line, and seven extrusion lines, with annual production capacities of 150,000 tonnes of aluminium alloy rods, 50,000 tonnes of aluminium alloy ingots, and 50,000 tonnes of aluminium and magnesium extruded profiles.
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).
