AI-Powered Sensor Systems for High-Purity Steel Scrap Recycling

manufacturingPilotedTRL 6

Imagine trying to bake a cake with ingredients that are mixed with random bits of plastic and dirt. This project builds a high-tech 'scanner' for scrap metal that tells steelmakers exactly what is in their metal piles before they melt them. By using AI and sensors, it cleans up the recycling process so we can use more low-grade waste to make high-quality steel.

The business problem

What needed solving

Steelmakers struggle to use low-quality recycled scrap because impurities make the final metal too unstable for high-grade engineering needs. This forces a reliance on expensive virgin materials and increases CO2 emissions.

The solution

What was built

Two industrial sensor stations: one for heavy (cut) scrap and one for shredded scrap. These stations use AI and sensors to analyze the chemistry, size, and shape of metal batches.

Who can put this to work

Steel Production
enterprise
Target: Electric Arc Furnace (EAF) operator

If you are an EAF operator dealing with inconsistent metal quality in post-consumer scrap — this project developed sensor stations that provide chemical analysis of 5-20 tonne batches. This allows you to increase the use of low-quality scrap by 40% while maintaining high-grade steel standards.

Waste Management
mid-size
Target: Scrap metal recycling facility

If you are a recycling facility dealing with impurities in shredded and heavy scrap — this project developed AI-supported sensor stations. These tools provide direct feedback to optimize shredders and magnets for better impurity removal.

Automotive Manufacturing
enterprise
Target: Specialty steel supplier

If you are a supplier producing high-performance parts like 42CrMo4 engineering steel — this project developed a way to use more recycled post-consumer scrap without compromising metal purity. This reduces the reliance on virgin materials and lowers CO2 emissions.

Frequently asked

Quick answers

What is the cost or price of the sensor stations?

Based on available project data, the specific cost or pricing model for the sensor stations is not disclosed.

Is this technology tested at an industrial scale?

Yes, the sensor stations are being implemented and demonstrated at an industrial scale at a scrap supplier site operated by Stena Recycling.

How is the IP or licensing handled for these sensors?

Based on available project data, there is no specific information regarding the IP or licensing terms for the developed technology.

How does this integrate into existing scrap processing?

The system integrates directly into the processing chains for both heavy (cut) and shredded scrap, providing data on chemistry, size, and shape for batches of 5-20 tonnes.

What is the timeline for deployment?

The project runs from 2023-01-01 to 2027-03-31, with initial requirement investigations completed in 2023 and sensor configuration performed in 2024.

Consortium

Who built it

The consortium is highly industry-driven, with 50% of the 12 partners being industrial actors (6 companies). This balance, combined with 3 universities and 3 research centers across 6 European countries, indicates a strong focus on commercial viability and industrial application rather than pure theory. The inclusion of SMEs (2) and a major recycler like Stena Recycling ensures the technology is built for real-world operational environments.
