Gerhard Lang Recycling and Tomra Join Forces for Advanced Aluminum Alloy Sorting

Collaboration to Enhance Efficiency in Automotive Aluminum Scrap RecyclingThe process of aluminum alloy recycling is key to improving efficiency and sustainability in the automotive industry.

In a significant step toward improving recycling practices, Gerhard Lang Recycling GmbH, a German leader in metal recycling, has partnered with Tomra Recycling to revolutionize aluminum alloy sorting. The collaboration, launched at Gerhard Lang’s sorting plant in Gaggenau, Germany, introduces Tomra’s cutting-edge Autosort Pulse system. It marks a critical milestone in the KANAL project.

New Technology Promises Higher Purity in Aluminum Scrap

The KANAL project, which stands for “Circular System for Functional Aluminum Scrap Recycling from Automotive Production Using LIBS,” focuses on improving the recycling of aluminum scrap produced in the automotive industry. The project received €3.9 million ($4.08 million) in funding from the German Federal Ministry for Economic Affairs and Climate Action. Along with Gerhard Lang Recycling, Tomra Recycling, Pforzheim University of Applied Sciences, and Jeanvré engineers have teamed up for the initiative.

Aluminum scrap makes up 30% to 50% of the aluminum used in car parts and panels. It is typically a blend of 5xxx and 6xxx alloys. The introduction of Tomra’s Autosort Pulse technology allows Gerhard Lang’s plant to sort these alloys based on their precise elemental composition using laser-induced plasma spectroscopy (LIBS). This advanced method will enable the facility to separate aluminum alloys with exceptional accuracy. It will achieve high purity levels of up to 97%.

Enhancing Sorting Efficiency and Maximizing Material Value

The new sorting process brings substantial improvements. Previously, Gerhard Lang Recycling sold mixed material immediately after the shredding stage. Now, with the installation of the Autosort Pulse, the company can process 4-7 tons of aluminum scrap per hour. This ensures the material meets the quality standards for direct integration into aluminum production. The system’s 3D scanning technology maximizes the yield by accurately identifying and separating overlapping materials. This is a common challenge in recycling.

Tomra’s market strategy manager, Frank van de Winkel, highlighted the importance of this technology. He stated that it supports the EU’s climate neutrality goals. “Our Autosort Pulse system helps aluminum manufacturers enhance their use of recycled aluminum, ensuring a more sustainable supply chain,” he said.

Impact on the EU’s Green Deal and Global Recycling Practices

The KANAL project aligns with the European Union’s ambitious Green Deal, which aims for carbon neutrality by 2050. By focusing on closed-loop recycling, the project helps eliminate the issue of downcycling, preserving material value. It also promotes a circular economy. This innovative approach will reduce carbon emissions in aluminum production, making the industry more sustainable.

Gerhard Lang Recycling’s Managing Director, Maximilian Lang, emphasized the company’s commitment to innovation. He said, “With the Autosort Pulse, we are now able to recover high-quality, ‘alloy-true’ aluminum for reuse in the production of new aluminum alloys.”

Expanding Recycling Potential in North America

In an effort to make this technology available worldwide, North American recyclers now have the chance to test their aluminum scrap at the newly equipped Wendt Corp. Test Center in Buffalo, New York. This facility is expected to become a key testing ground for the Autosort Pulse system. It will allow recyclers to benefit from the same advancements seen in Europe.
