Industrial-Scale Scrap Cleaning and Sorting to Produce High-Quality Green Steel

manufacturingPilotedTRL 7

Imagine trying to bake a gourmet cake but your flour is mixed with pebbles and plastic. This project builds a giant 'filter' for the steel industry to clean out impurities from old, low-quality scrap metal. By sorting out the junk, they can turn old waste into high-grade steel without needing as much raw ore. It's like turning a messy junkyard into a goldmine of pure raw materials.

The business problem

What needed solving

Steelmakers cannot use increasing volumes of post-consumer scrap because it is too low-quality and contaminated, forcing a reliance on expensive and high-emission virgin iron ore.

The solution

What was built

A system of integrated scrap upgrading, sorting, and characterization technologies validated at industrial scale.

Business applications

Who can put this to work

Steel Manufacturing
enterprise
Target: Electric Arc Furnace (EAF) operators

If you are an EAF operator dealing with the rising complexity of post-consumer scrap — this project developed integrated sorting and characterization technologies that allow you to use low-quality streams while maintaining high-quality steel standards.

Waste Management
mid-size
Target: Metal scrap processors

If you are a scrap processor dealing with non-ferrous fractions and pollutants in end-of-life products — this project developed valorization routes that turn these waste fractions into revenue, moving toward zero waste.

Automotive/Industrial Equipment
enterprise
Target: High-end steel product manufacturers

If you are a manufacturer dealing with the need for climate-neutral materials — this project developed a way to increase scrap recycling capacity, reducing the reliance on virgin iron ore and lowering CO2 emissions.

Frequently asked

Quick answers

What is the industrial scale of this technology?

The project aims for demonstration at full-size industrial scale for integrated scrap upgrading, sorting, and characterization technologies.

How does this affect production costs and energy?

Increasing the scrap ratio in steelmaking drastically reduces CO2 emissions and energy consumption compared to using virgin raw materials.

What is the IP or licensing status?

Based on available project data, specific licensing terms are not listed, but the project involves 9 industrial partners and 3 research centers developing these technologies.

How does this help with EU regulations?

The technology aligns with the European Green Deal and the CleanSteel Partnership's vision for a climate-neutral steel sector.

When will the results be fully available?

The project period runs from 2022-06-01 to 2026-05-31, suggesting full validation by mid-2026.

Consortium

Who built it

The consortium is heavily industry-driven, with 9 industrial partners representing a 69% industry ratio. This strong commercial presence, combined with 3 research centers and 1 university across 5 European countries, indicates that the project is focused on commercial viability and industrial integration rather than theoretical research.
