Leadership in cleaner, more efficient refining.

Technology developed by our Refining Center of Excellence in Australia over the prior decade has steadily increased our system-wide capacity by the equivalent of a new refinery without greenfield development.

Advanced technologies such as Mechanical Vapor Recompression (MVR), currently being tested in Australia, are helping maintain our lead in low-carbon refining. In addition, Alcoa refineries have led the way in ISO9001 and ISO14001 certifications for quality and environmental performance.


We sell more than half our production externally.

The majority of our alumina is sold to third parties. We provide smelter-grade alumina, including EcoSource™, to manufacturers worldwide, with operations strategically located for access to growing markets in Asia and the Middle East.

We also produce non-metallurgical grade alumina for sale to customers in North America, South America, Europe and Asia.
