Industrial green storage silos against a clear sky

Transforming hazardous steel waste into clean water and green energy.

Recycling steel waste into valuable resources for circular iron chloride production

Anferra is a Sweden-based startup on a mission to increase circularity across industries. We turn hazardous grinding sludge from steel manufacturing into high-purity iron chloride for water treatment — while recovering hydrogen and recyclable alloys along the way.
