1 min read

Alcoa Corporation has received certification from the Aluminium Stewardship Initiative (ASI) for its aluminum mine in Poços de Caldas, Brazil.

The site is the company’s sole producer of aluminum powder, Alcoa said.

All of its operating locations in Brazil are now ASI certified, while globally 17 Alcoa sites have received Performance Standard certification from the international non-profit certification organization, according to the company.

The Poços de Caldas site was founded in 1965 and includes a bauxite mine, alumina refinery, and aluminum casthouse.

“This certification marks an important milestone in our efforts to ensure that all of our Brazilian operations adhere to the highest sustainability standards,” said Otavio Carvalheira, Alcoa’s president of Brazil and vice president of operations.

The ASI Certification program is applicable to both upstream producers and downstream manufacturers. It covers environmental, social, and governance (ESG) issues affecting the entire aluminum value chain, such as greenhouse gas emissions, biodiversity, and human rights, Alcoa said.

The company also plans to implement press filtration for bauxite residue at the Brazil site.
