Multinational Alcoa Corporation has announced that its Massena plant in New York has achieved provisional Aluminum Stewardship Initiative (ASI) certification for its smelter. Massena is the oldest continuously operating smelter in the world, with aluminum production beginning in 1902. During its long history of manufacturing excellence, the smelter has undergone numerous upgrades and currently has a rated capacity of 130,000 metric tons, all powered by renewable hydroelectric power.

Specifically, the ASI certification program is the most comprehensive in the industry, developed through a consultative process that highlights strong environmental, social and governance (ESG) principles and criteria, including key issues such as biodiversity, indigenous peoples’ rights and greenhouse gases.

John Slaven, Alcoa’s executive vice president and chief operating officer, says, “Achieving ASI certifications aligns with our vision of reinventing the aluminum industry for a sustainable future. In addition, this recognition for the company is good news for the facility’s 120 years of continuous production and the important work our employees do there every day to constantly improve for the benefit of our customers, communities and the environment.”

ASI certification will bring the total number of Alcoa facilities certified to these standards to 16 sites worldwide. In addition, Alcoa is now also ASI Chain of Custody certified, which allows the company to market and sell ASI-certified aluminum worldwide. The Performance Standard and Chain of Custody (CoC) certifications align with two of Alcoa’s main sustainability objectives: improving the company’s operational footprint and increasing the value of its products through differentiation.
