Strengthening circular processes in the steel industry
Luleå University of Technology is participating in a new research project aimed at facilitating the use of recycled steel in future carbon-neutral production. By addressing challenges related to the material’s properties, the project can contribute to a more sustainable and circular steel industry.
With an increased share of recycled steel in the manufacturing process, greater variations in the material’s properties arise, which can affect the quality of the steel. The research project Carbon-Neutral Steel in a Circular Economy investigates how these variations can be reduced and how the steel’s properties can be ensured throughout the entire value chain.
A More Robust Process
A key part of the project is studying the accumulation of alloying elements and their impact on the mechanical and chemical properties of steel. The researchers will also develop new testing methods to ensure that recycled steel meets industry standards.
"By understanding how alloying elements build up and affect the material, we can create a more robust process for recycled steel," says Hans Åhlin, project coordinator at the Centre for High performance Steel at Luleå University of Technology.

Improving the Use of Recycled Material
For steel production to become more circular, better sorting and characterization of scrap are required, along with manufacturing processes capable of handling a wider variation in input materials. The project will provide recommendations on how the industry can adapt its processes to efficiently utilize recycled material without compromising quality.
"By mapping the relationship between the material’s chemical composition and its mechanical properties, we can contribute to a more predictable and efficient production of carbon-neutral steel," says Erik Olsson, Associate Professor of Solid Mechanics at Luleå University of Technology.
The research has the potential to bring significant positive effects for both the industry and the environment. A more circular steel production process can reduce resource consumption while strengthening the competitiveness of Swedish steel manufacturing.
"This is an important step toward a sustainable and circular steel industry, where we make smarter use of resources," says Hans Åhlin.
The facts
The project is funded by the Just Transition Fund, with a total budget of SEK 15.5 million. The project is carried out in close collaboration with industry, ensuring a close link to applied research and practical implementation.
