Alumina Limited is a Western Australia–based investment company whose primary asset is a 40% interest in Alcoa World Alumina & Chemicals (AWAC), a leading global alumina and bauxite producer. Established in 1994, the firm was created to consolidate Alcoa’s interests in bauxite mining, alumina refining and aluminium smelting into a single joint venture entity. Headquartered in Perth, Alumina operates through a strategic partnership with Alcoa Corp., drawing on more than a century of combined expertise in refining technology, resource development and commodity marketing.
AWAC’s integrated operations span bauxite mines in Western Australia and Guinea, alumina refineries in Australia (including Pinjarra, Kwinana and Worsley), Brazil and Spain, as well as aluminium smelters in Australia, Brazil, Spain and the United States. Through its 40% holding in AWAC, Alumina Limited benefits from a diversified portfolio of low-cost, high-quality alumina production assets that supply metallurgical-grade alumina to aluminium smelters around the world. The company’s interest in each stage of the alumina and aluminium value chain provides resilience against commodity price cycles and delivers long-term cash flow generation.*
Alumina Limited focuses on maximising shareholder value through prudent capital management, disciplined cost control and sustainable growth initiatives. While it does not directly manage day-to-day mining or refining operations, the company actively engages with AWAC’s leadership and global management teams to ensure alignment on safety, environmental stewardship and community development. AWAC’s extensive research and development programs have yielded advancements in energy efficiency, process optimisation and emissions reduction, underpinning Alumina’s commitment to responsible resource development.
Governed by an independent board of directors with deep experience in mining, finance and corporate governance, Alumina Limited maintains offices in Perth and London to support its international operations. The company places strong emphasis on transparent stakeholder engagement and adheres to rigorous environmental, social and governance (ESG) standards. Through its partnership in AWAC, Alumina Limited remains positioned as a key participant in the global alumina market, supplying critical materials to the aluminium industry while pursuing sustainable practices and long-term value creation for shareholders.
