Tomra launches AI-based solution to enhance wrought aluminium purity

Tomra Recycling has launched an AI solution which enables aluminium scrap processors and recyclers to upgrade their wrought scrap.

The solution, called Gainnnext, is Tomra’s first AI technology in the metals industry.

It enables aluminium scrap processors and recyclers to upgrade their wrought aluminium scrap and produce high purity fractions by instantly recovering low alloy cast from the wrought fraction and reducing alloying elements such as silicon.

The technology complements Tomra’s X-Tract technology, which separates based on atomic density.

By integrating Gainnext into the sorting process after X-Tract a pure wrought fraction can be achieved.

According to the company, Gainnext leverages the power of deep learning and artificial neural networks.

Using RGB cameras, it rapidly processes tens to hundreds of thousands of images per millisecond, ‘perceiving’ and ‘classifying’ materials by shape, size and dimension.

This system, trained over years by the company’s experts, mimics human vision but with superior speed, facilitating high throughput sorting of up to 2,000 ejections per minute.

In its first metals industry application, by detecting and removing low alloy cast from the wrought fraction that X-Tract produces, Gainnext can deliver a high purity wrought product that commands premium market prices, the company said.

Tom Jansen, Head of the Metals Segment, Sales at Tomra Recycling, said: “Deep learning is a powerful addition to our traditional sensor-based technology, and expanding our Gainnext ecosystem aligns with our broader AI strategy.”

He added: “This latest application enhances dry mechanical sorting of mixed metals, offering a cost-effective solution with a low cost per ton thanks to its high throughput and reduced manual sorting requirements.

“This is an enhancement to our metal recycling solutions portfolio, and we anticipate wide adoption by recyclers seeking to refine scrap and generate high-quality feedstock for circular manufacturing.”
