The recycling process developed by Anferra targets the steel and bearing industry's most stubborn waste stream. By chemically treating grinding sludge, the startup extracts ferric chloride, a substance widely utilized in water purification and treatment facilities. Beyond this chemical output, the method generates hydrogen gas, offering a secondary path for energy storage.

Mikael Krook, director of SKF Ventures, identified the sludge as a significant hurdle for circular manufacturing. By integrating this technology, SKF intends to accelerate its decarbonization efforts. Financial terms of the investment remain undisclosed, but the collaboration signals a shift toward capturing value from industrial byproducts previously considered difficult to manage.
