Targeted SDGs
Anferra's solution contributes positively across several Sustainable Development Goals — starting with responsible consumption and production, plus clean water and sanitation, affordable and clean energy, and industry innovation and infrastructure.
Scaled impact: Global potential
Steel grinding sludge is a large untapped resource worldwide. Applied at industrial scale, Anferra's process could unlock major volumes of valuable outputs.
Recycling 12 kilotons of sludge could offset around 100,000 tons of CO₂ per year.
At a typical 60 mg/L dose, that volume of ferric chloride could support water treatment for tens of millions of people annually.
A 5 kt/y scaled process could also generate enough green hydrogen to power thousands of households a year, and recover thousands of tons of alloys for reuse in the steel value chain.
