Australia’s Most Sustainable Rebar
We are proud to produce Australia’s most sustainable rebar, setting a new benchmark for low-emission, high-quality steel.
Using the latest in electric arc furnace technology from our technology partner Danieli, we generate less than 370 kg of CO₂ per tonne of rebar produced — a reduction of up to 80% compared to traditional steelmaking.
This groundbreaking approach is driving the revitalisation of the Australian steel industry while supporting a greener, more resilient future as we strive for a world of green steel.
At the heart of this transformation is our commitment to green manufacturing, playing a key role in creating a Just Transition for one of Australia’s iconic coal towns by helping transform it into a hub for sustainable industry.
We are ensuring that Australian-made steel remains competitive by harnessing renewable energy and cutting-edge technology.
We are working closely with our industry partners to develop innovative and sustainable business practices that add value throughout the entire rebar supply chain—from the mill gate to the job site. By optimising efficiency and sustainability at every stage, we are helping to create smarter, cleaner, and more cost-effective solutions for the construction and infrastructure sectors.
Together, we are building a stronger, cleaner, and more self-sufficient Australia—one tonne of green steel at a time.

About Recycling Steel
Steel recycling is a well-proven, low-risk way to produce green steel
Australia currently exports more than 2.5 million tonnes per year of scrap steel, which is more than half of what is recovered.
Western Australia exports 100% of its scrap steel as there are no steel mills in the state.
This results in more than 700,000 tonnes of scrap steel being exported out of WA every year, most which is destined for Asia.
Scrap exports continue to grow
Increasing population and a growing economy, combined with a stagnant steel recycling industry across the country results in more and more scrap steel being exported out of Australia each year.
Significant growth in scrap volumes are expected in the next one to five years due to the decommissioning of major oil and gas facilities on top of industry and population growth.

WA will have more than 60% of Australia’s offshore decommissioning amounting to more than 3 million tonnes of scrap steel.
Steel recycling is a rapidly growing business, but not in Australia
The US has built more than 30 new steel mills in the last 30 years
Recycling electric arc furnace mills are rapidly replacing old, highly polluting blast furnaces across the US. Highly automated and clean, these mills are both economically and environmentally sustainable.
Australia has not built a single new steel mill in that time
Australia's aging steel mills are likely to face higher costs as they require maintenance and upgrades, are highly emissive and almost impossible to decarbonise. This combined with Carbon Border Adjustment Mechanisms (CBAM) is expected to lead to an overall increase in the price of steel in Australia.

The Collie Steel Mill will create WA's circular economy for steel

A recognised project of state significance
Green Steel of WA is fully aligned with local, state and federal government green manufacturing and steel decarbonisation objectives.
Our Collie Steel Mill is a designated Strategic Project under the Western Australian government's Lead Agency framework.
"It is with great pleasure I can advise that the Collie Green Steel Project has been identified as a Strategic Project under the Lead Agency Framework..."
Premier Roger Cook
"Green Steel of WA (is) moving forward with significant projects that will position Collie as a leading hub for emerging industries in Australia."
Former Premier Mark McGowan
Proudly working together for success
Principal technology partner
Green Steel of WA has secured a technology partnership with global steelmaking leader Danieli, which has been providing innovative steelmaking solutions around the world for more than 100 years.
During this time, Danieli has delivered more than 100 turnkey plants, giving them unparalleled experience in this field.
By combining Green Steel’s project development expertise in Western Australia with Danieli’s green steel expertise, we believe we will be able to rapidly kick-start Western Australia’s green steel and green hydrogen industries.
Helping Create a Just Transition in one of Australia's Iconic Coal Towns
Climate action, while in the best interest of Australia and the world, will have an impact on a significant portion of Collie’s workforce who are tied to carbon-intensive industries (power and coal) and have been so for generations. These impacts are expected to begin as early as 2025. Collie’s Just Transition Plan is seeking to create new options for them and the town.
Regional steel mini-mills have a transformative effect on the region
Experience around the globe shows regional steel mini-mills create a mini-economic ecosystem, attracting other related industries that cluster around them.
This means the Collie Steel Mill will not just create a significant number of jobs in Collie, but will also act as a catalyst for the establishment of future industries and act as an enabler for large-scale green-energy-intensive industry.
New jobs for Collie's highly skilled workforce
Collie’s transition and thus the availability of a highly skilled workforce with transferable skills was one of the key drivers for our plant location.
We are continuing to engage and work closely with the government, stakeholders, workers and their representatives to develop and implement an effective, fair and transparent transition plan that will benefit both workers and our operations alike.
A genuine project with almost no technical risks
Unlike many new projects, the Collie Steel Mill is based on a proven business model and technology employed in similar communities around the globe.
Environmentally friendly and energy efficient, mini-mills are a rapidly growing industry in the US, growing 15% to over 50% of total market share in the last 30 years

WA's coal-fired power stations will be retired by 2030

Transitioning Collie's workforce
Identify skills
Because the mill is 'cut and paste' from the US, we know role-for-role exactly what skills are required, which overlap broadly with those of the workers in coal mining, power generation, and other related heavy industries.
Engage and Plan
We will engage with the government, workers, and their representatives and key stakeholders to understand the workforce and develop a practical transition plan that matches workers to opportunities, and identifies training gaps to be filled.
Transition
We begin our investment in the future of the people of Collie by implementing our agreed transition plan to create our future workforce shortly after the project commences execution.
Operate
With a well-trained, high-quality workforce, the transition from a construction site to a fully operational steel mill occurs within a few short months. The mill attracts new industries to the area creating further jobs and growing the local economy.
Significant job creation and economic contribution
The Collie Steel Mill will require a large skilled industrial workforce to operate the mill and to provide supporting services.
Collie’s existing mining, manufacturing, energy and construction workforce who are likely to be most impacted by Collie’s Transition are an excellent fit, requiring minimal reskilling to effectively support the plant.
