The future is made of aluminum


Aluminum has become an important enabler of low carbon products and solutions that are better for both the environment and society. We believe the future is made of aluminum—and at CBA this future has been here for years, with ESG commitments spanning our entire production process.

Operation highlights in 2022:


Sustainable mining

CBA reclaims decommissioned mine sites for use in agricultural activities, and fully integrates them with the surrounding landscape through reforestation. We return the land to landowners in better condition than before it was mined. Using a new and more effective reforestation method, in 2022 CBA planted more than 90,000 large-sized saplings of species native to the Atlantic Forest in reforestation areas.



In 2022 we acquired a 100% equity interest in Alux do Brasil, marking our entry into the secondary aluminum alloy market. At Metalex, we started a new sidewell furnace and continued work on a new scrap treatment line that is due to start operation in mid-2023. In addition, CBA established partnerships to further expand our sources of scrap material during the year.


Primary Business - Accelerated restart of Pot room 3

We restarted Pot room 3 ahead of schedule in 2022, increasing our production capacity while introducing a new technology that minimizes carbon emissions. In addition, our Alumina Refinery currently boasts the lowest greenhouse gas emissions level in the world*.

*According to emissions estimates from the CRU Platform.


Energy Business

As another important milestone in the year, we took over the management of 23 hydroelectric power plants that were previously managed by Votorantim Energia (now renamed Auren) in 6 Brazilian states, including 17 wholly-owned and 6 jointly-owned power plants. These plants have an installed capacity that meets the entire electricity requirement of our Alumínio plant.
