Alcoa recently announced a new Carbon Capture system at its Kwinana alumina refinery in Western Australia. The residue treatment process involves mixing bauxite residue, a by-product of the aluminum making process, with carbon dioxide (CO2). The system delivers greenhouse benefits by locking up large volumes of CO2 that would otherwise be released to the atmosphere.

The Kwinana carbonation plant will lock up 70,000 tons of CO2 a year, the equivalent of eliminating the emissions of 17,500 automobiles. As part of its ongoing commitment to reduce its global emissions, Alcoa plans to deploy the technology to its nine alumina refineries worldwide. Deployment across Alcoa’s operations in Australia alone could potentially save 300,000 tons of CO2 each year.
