Transforming hazardous steel waste into clean water and green energy.

Recycling Steel Waste into Valuable Resources for Circular Iron Chloride Production At Anferra, we convert grinding sludge and swarf, two of the steel industry's most persistent waste challenges, into essential and valuable resources.

Anferra’s hydrometallurgical process creates circularity between the steel and chemical industries by enabling the exchange of recovered materials.

We help steel processing companies reduce landfilling and disposal costs, while enabling chemical producers to replace virgin iron with recycled iron in the production of iron chloride — a critical component in clean water treatment.

By turning hazardous waste into a resource, our process delivers both environmental and economic benefits.

From Waste to Resource
Grinding sludge from low-alloy steel is usually classified as hazardous and disposed of at high cost, despite containing valuable materials.

How Anferra Makes a Difference
Through our patented process, we recover these materials by producing high-purity iron chloride and green hydrogen. This reduces landfill, lowers disposal costs, and enables circular use of critical resources.

Reduced waste management costs

Increased recycling rate of grinding swarf

High-quality water treatment chemicals

Industrial symbiosis and climate benefits
