SKF Backs Anferra to Turn Steel Grinding Sludge into Circular Resources
Event summary
- SKF, Stephen Industries, and Chalmers Ventures invested in Anferra AB to recycle hazardous steel grinding sludge into ferric chloride and hydrogen gas.
- Anferra's process achieves up to 90% iron recovery with a net climate benefit of negative 470 kg CO₂e per tonne of sludge compared to conventional disposal.
- The investment is the first initiative from SKF Ventures, aimed at accelerating circular recycling innovations in the steel and bearing industry.
The big picture
SKF's investment in Anferra underscores the growing emphasis on circular economy solutions within heavy industry. The deal aligns with broader EU efforts to standardize waste regulations and promote secondary raw materials, positioning SKF as a first mover in transforming industrial waste into valuable resources. With global steel grinding sludge production at 12 million tonnes annually, the potential market impact is significant.
