Anferra uses a proprietary hydrometallurgical process to convert hazardous steel grinding sludge into high‑purity iron chloride for water‑treatment and hydrogen gas as a clean‑energy by‑product. This enables steel processors to cut disposal costs and eliminates landfill waste, while chemical manufacturers can replace virgin iron with recycled iron chloride, supporting circular economy and reducing carbon emissions.

Problem
Steel processing plants generate grinding sludge that is classified as hazardous waste, leading to high disposal costs and environmental concerns despite containing valuable iron content. The lack of a viable recycling pathway forces companies to landfill this material, missing opportunities for resource recovery and circular use.
Solution
Anferra applies a proprietary hydrometallurgical process to convert steel grinding sludge into high-purity iron chloride and hydrogen gas. The recovered iron chloride serves as a key reagent for water‑treatment applications, while the co‑produced hydrogen can be utilized as clean energy. By transforming hazardous waste into marketable chemicals, the technology lowers landfill and disposal expenses for steel producers and provides chemical manufacturers with a sustainable, low‑cost alternative to virgin iron sources. The process also creates industrial symbiosis, reducing overall carbon emissions and supporting circular economy goals across the steel and chemical sectors.
Target Audience
Primary customers are steel processing companies seeking to reduce waste disposal costs and chemical manufacturers that require iron chloride for water‑treatment processes.
