The Aluminium Stewardship Initiative (ASI) certified three Alcoa-operated locations, one in each of the company’s three business units. The ASI certifications are valid for three years and include the Juruti bauxite mine in Brazil, the Alumar alumina refinery near São Luís, Brazil and the aluminum smelter in San Ciprián, Spain.

ASI is a global sustainability certification program for the aluminum industry, representing both upstream producers and downstream manufacturers that use the metal in their products.
