New Study Confirms Climate Benefits of Anferra’s Steel Waste Recycling
Anferra is pleased to share the results of a newly published environmental study, conducted in collaboration with AB SKF and IVL. The report evaluates the climate performance of Anferra’s process for recycling steel grinding sludge into ferric chloride. It was carried out as part of the Swedish Metals & Minerals Impact Innovation program – a joint initiative by the Swedish Energy Agency, Formas and Vinnova.
The study shows that Anferra’s process delivers a net climate benefit of around –350 kg CO₂‑equivalents per ton of sludge, the process has a lower carbon footprint than incineration and a comparable or lower footprint than the range of electric arc furnace (EAF) recycling scenarios. In other words, the report confirms that Anferra’s technology provides a significant climate benefit relative to current state-of-the-art methods.
The recycled ferric chloride performs on par with conventional production from virgin magnetite in terms of climate footprint – and could become even more advantageous if by‑products such as steam and abrasives are recovered and reused.

Why this matters
The results provide important third‑party validation of Anferra’s technology and its environmental impact at an early stage. This adds a solid foundation for upcoming steps, particularly as Anferra prepares for large‑scale pilot implementation.
The project was carried out in collaboration with SKF, SSAB, Scania, Sydvatten, IVL and Chalmers Industriteknik, with funding and coordination from the Swedish Metals & Minerals Impact Innovation program.
We thank our partners for their contributions and look forward to continuing this work to scale sustainable, circular solutions within the steel and chemicals industries.

Anferra Selected Among Top 40 Women TechEU Startups in Europe
Anferra has been selected as one of this year’s 40 Women TechEU winners, chosen from over 1,000 applications across Europe!
Women TechEU is an EU-funded program that supports women leading deep tech startups by providing both financial backing and tailored mentoring. As part of the program, Anferra will receive €75,000 in funding and valuable support to continue scaling our technology and impact.
At Anferra, we transform hazardous steel waste into valuable resources for clean water and green energy. By enabling circular flows between the steel and chemical industries, we’re reducing landfilling, lowering CO₂ emissions, and creating sustainable raw material alternatives.
Anferra among the Top 10 on Företagarna’s 103 Young Ideas 2025
We’re proud to share that Anferra has been recognised as one of the top ten leading companies on Företagarna’s annual 103 unga idéer list, which spotlights Sweden’s most promising ventures founded by entrepreneurs under 35.
This recognition highlights the impact of our circular technology that converts steel-industry grinding sludge into green hydrogen and iron chloride for water purification. Turning a hazardous waste stream into valuable resources while reducing emissions.
We’re honoured to stand alongside so many impressive initiatives and grateful for this support that makes our progress possible.
