Bio-syngas-Driven Fossil-Free Ferrochrome Production (Bio4FeCr)

Chromite ore is the primary material used to produce ferrochrome (FeCr), a vital component in stainless steel manufacturing. Traditionally, FeCr production relies on fossil carbon, leading to significant CO₂ emissions. This project aims to revolutionize the process by exploring renewable reductants such as bio-syngas and hydrogen for chromite ore pre-reduction. By reducing carbon emissions and optimizing production costs, the project supports Sweden’s vision of a fossil-free economy and facilitates a transition to more sustainable FeCr production.

A collaboration between Luleå University of Technology (LTU) and Vargön Alloys AB, the Bio4FeCr project focuses on innovative solutions to transform the industry.

Key areas of exploration include:

• Pre-oxidation to improve chromite ore reactivity
• Mechanical activation and mixing with pre-reduced FeCr
• Comprehensive assessment of technical, economic, and environmental feasibility

By implementing these methods, the project strives to achieve a cleaner, more cost-efficient production process while aligning with global sustainability goals.

This project is funded under the Metals & Minerals program, part of the Impact Innovation initiative, a collaborative effort by the Swedish Energy Agency, Formas, and Vinnova.
