Alcoa announces permanent closure of Kwinana refinery
Alcoa will incur $890 million in restructuring charges in 2025 and reduce its Kwinana refinery workforce from 220 as closure progresses during 2026.
- On September 29, 2025, Alcoa Corporation announced its decision to shut down operations indefinitely at its alumina refinery located in Kwinana, Western Australia, following a reduction in production that began in June 2024.
- The closure decision followed a thorough assessment by COO Matt Reed, who said Alcoa explored multiple options but found no sustainable path to restart the ageing facility.
- By 2025, the refinery's workforce had been reduced to approximately 220 employees following a gradual staff phase-out starting in January 2024. This facility contributed to about 16% of Alcoa's total alumina refining output, which was 13.9 million tonnes worldwide.
- Alcoa expects closure costs to total around US$890 million in 2025 with restructuring charges of $623 million after-tax and an additional $600 million over six years, while noting significant industry pressures.
- Alcoa plans to collaborate with the Western Australian government and key stakeholders to ensure a safe closure of the refinery, facilitate site redevelopment, and provide support for affected employees, while maintaining its other operations in the region.
