Anferra increases the circularity in the steel- and chemical industries.
Our process
Every time steel is shaped or polished using cutting oils, a waste called grinding swarf, or sludge, is generated. It’s classified as hazardous, and difficult to recycle into new steel, why it is commonly being landfilled or destructed.
Our patent-pending process offers a resource- and cost efficient method to extract iron from steel grinding swarf and convert it into iron chloride, a coagulant commonly used in water treatment with a high, increasing demand.
We are today able to produce an iron chloride solution with purity levels that meet European standards for treating drinking water (EN 888:2004). From 1 ton of grinding swarf we can produce 5 tons of iron chloride. Hydrogen gas is also generated in the process, which can be converted into electricity or used in industrial processes such as in reduction of fossil free steel.
The remaining high value metals, cutting oils and abrasives, can be filtered out and used as input material for stainless steel production.
Ferric Chloride
Our Ferric Chloride is of high commercial quality and purity (CEN). By collaborating with established producers and resellers of Iron based coagulants, we are increasing the availability of high quality water purification chemicals made from recycled iron, reducing the dependence of virgin iron ore.
H2
Green hydrogen is expected to play a significant role in the future energy system and in decarbonizing heavy industries. Utilization of the hydrogen gas generated in our process can be adapted to fulfill the needs of the surrounding industrial system – in other chemical or mettalurgical processes, as electricity or fuel for transportation.

Solids
The solid output contains higher concentrations of alloying elements such as Molybdenum and Chromium, valuable in the production of stainless steel. By making the solid byproducts available for reuse, Anferra aims to recycle and reuse 100% of the grinding swarf.
