Alcoa in Australia

Across Alcoa, you’ll find experienced operators with innovative processes and industry know-how. But it’s not just what we produce, it's how we do it. Responsible production is embedded in our Alcoa values and in Australia and around the world we are consistently recognised for our approach to sustainability.

Since our Australian operations began in 1963, we have built a reputation as leaders in environmental management. Alcoa is among the world’s lowest CO₂ emitting alumina producers and our Australian business was the first mining company to receive recognition from the United Nations for rehabilitation excellence. Our teams are working daily to develop and lead new and innovative processes to help achieve our Net Zero ambition and our shared corporate vision to reinvent the industry for a more sustainable future.

From mine to finished metal, we produce our products with a focus on the environment and our communities and we’re proud of our role to create shared value in the places where we operate. In Australia, annual spend is more than $4 billion locally through wages, taxes, royalties, procurement and community investment.

As we look to the future, we will strive to continue to lead our industry with courage. We will embrace opportunities to reinvent, innovate and challenge the status quo.

In Australia, we operate one of the world’s largest integrated bauxite mining, alumina refining and aluminium smelting systems.

With six decades of production under our belt, we appreciate the energy, integrity, talent and determination to succeed of the thousands of people who built Alcoa as we currently know it.

In 2023, our two bauxite mines and three alumina refineries in Western Australia produced approximately 50 per cent of Australia’s alumina, and our Portland Aluminium Smelter in Victoria produced 18 per cent of the nation’s aluminium. We also operate two dedicated port facilities and two farmlands in Western Australia.

These locations are known for being among the most cost-efficient, technologically advanced and environmentally conscious in our industry.

Aluminium is the world’s most versatile metal, used every day by everyone. From aluminium foil in your kitchen, the minerals in your laptop and smart phone, the house you live in, the bike you ride, car you drive, to the plane you holiday with – we all rely on alumina and aluminium.

Our Australian operations represent one of the world’s largest integrated bauxite mining, alumina refining and aluminium smelting systems.

In 2023, we mined approximately 34 million dry metric tonnes of bauxite, refined about nine and a half million tonnes of alumina and produced approximately 280,000 tonnes of aluminium.

In Western Australia, we extract bauxite at our Huntly and Willowdale mines and conduct world-class rehabilitation. The bauxite is transported to our two refineries at Pinjarra and Wagerup where it is turned into alumina. This alumina is shipped to smelters around the world, including our Portland Smelter in Victoria, where it is turned into aluminium.

Our ability to deliver a consistent and reliable source of bauxite, alumina and aluminium is founded on our six decades of experience. Our team of about 4,370 brings specialist expertise including some of the most committed and talented individuals in our industry.

Our Australian mines, refineries and smelters are known across the globe for being at the forefront of operational and environmental excellence.

Today’s aluminium market demands producers be highly competitive on price, product quality and reliability, while demonstrating products are sustainably produced. It is our experienced and efficient locations and their specialty products that allow us to achieve these standards and deliver the required outcomes to our customers - giving us our competitive advantage.

Our operations include:

Two bauxite mines in Western Australia (Huntly and Willowdale)
Three alumina refineries in Western Australia (Kwinana*, Pinjarra and Wagerup)
One aluminium smelter in Victoria (Portland)
Two dedicated port facilities in Western Australia (Kwinana and Bunbury)
Two Alcoa Farmlands sites in Western Australia (Pinjarra and Wagerup)

We are also overseeing the ongoing decommissioning, remediation and/or rehabilitation of an aluminium smelter, coal mine and power station.

^*Kwinana refinery is being curtailed across 2024 and 2025. See corporate announcement for details.

We care about the environment and the communities near where we operate. Protection and preservation is core to our values and drives our commitment to the highest standards of environmental performance.

For decades, our team has included some of the most highly regarded environmental experts in the resources industry. It is their loyalty to Alcoa’s environmental commitments that led us to becoming a world leader in environmental management.

In October 2021, Alcoa announced its ambition to achieve net-zero greenhouse gas emissions across all global operations by 2050.

Our Australian locations will play an important part in this. Alcoa is already among the world’s lowest CO₂ emitting alumina producers and is at the forefront of the industry in leading the change. Proudly, we are developing new technologies that could remove almost 100 per cent of greenhouse gas emissions from the refining process.

Electric calcination
Electric calcination, when powered with renewable energy, has the potential to significantly reduce carbon emissions. Additionally, electrification of calciners would allow significant amounts of residual energy, currently lost in the atmosphere as steam, to be captured and reused, saving water and negating the need for stacks to vent that steam.

These achievements put us in the position to make a real difference and we are committed to doing so.

Our Australian operations manage environmental issues using a comprehensive environmental management system certified to international standard ISO 14001:2015. Our refinery quality management systems are certified to ISO 9001:2008.

We are proud to be part of Australia’s economic prosperity.

For six decades, we have created significant economic value by offering stable employment, procuring goods and services locally and investing in community infrastructure and initiatives.

Since 1963, more than $14.9 billion in capital investment has occurred in Australia. In 2023, 88 per cent of our revenue stayed in Australia through wages, local spend, taxes, royalties and dividends to Australian shareholders.

More specifically, in 2023 our Australian operations:

Invested $2.7 billion with 1520 Australian suppliers
Paid $397 million in State, Federal and local government taxes and royalties
Paid $831 million in Australian wages, salaries and associated benefits
Made $5.2 million in community contributions.

We are also one of Australia’s leading exporters, contributing around $4.5 billion in exports each year.

Generating this value allows local and regional communities to thrive and entrenches our position as a valued and welcomed community member.
