TOMRA launches AUTOSORT™ PULSE with dynamic LIBS technology

Global sensor-based sorting technology provider, TOMRA Recycling Sorting, introduces a new machine featuring dynamic laser-induced breakdown spectroscopy (LIBS). Designed for high throughput sorting of aluminium alloys, AUTOSORT™ PULSE redefines industry standards and paves the way for green aluminium.

Leveraging decades of experience in the metal recycling industry, the company celebrates its next milestone in the metal segment by introducing AUTOSORT™ PULSE to the market. Equipped with dynamic LIBS technology for high-precision aluminium scrap sorting by alloy types, the new sorting system can be used across various applications to create high-quality secondary metals.

As the metals industry strives to increase recycling rates to reduce energy consumption and new materials, the use of best-in-class sorting technology is indispensable. They recover pure mono materials from mixed scrap that can be further processed and turned into virgin-like material with high recycled content.

Frank van de Winkel, the Market Strategy Segment Manager of Metals at TOMRA Recycling Sorting, explains: “Aluminum scrap consists of multiple alloys. Depending on the application, they contain a mix of different alloying metals that define the material’s properties. To recycle a specific alloy without downgrading quality, it must be separated into specific alloy classes. This task can only be done with the most sophisticated technologies, such as LIBS. Our team of in-house engineers has dedicated significant time and effort to developing this technology to make it excel in performance. AUTOSORT™ PULSE allows recyclers to sort aluminium by alloy classes and produce furnace-ready products for demanding applications.”

Next-level alloy sorting

AUTOSORT™ PULSE combines leading-edge technology in one machine, enabling high-throughput production of green aluminium. Featuring the patented, dynamic LIBS technology, it delivers outstanding performance in the separation of, for example, 5xxx and 6xxx aluminium alloys. The machine’s 3D object scanning detects each object regardless of its size and surface, while multiple single-point scans enable sharper detection of materials in any condition. Thanks to its AI-based object singulation feature, even overlapping and adjacent objects can be accurately separated to maximize yield.

Conventional sorting machines like x-ray fluorescence (XRF) or standard LIBS technologies are limited in maintaining industry-level throughputs when sorting aluminium alloys.

AUTOSORT™ PULSE has a combination of the most innovative technologies, leading to peak precision and high-purity sorting results. Multiple material tests have demonstrated that purity levels of more than 95 per cent can be achieved.

High volume processing

With a bulk infeed system and a 3-7 tonnes/hour processing capacity, operators can create high volumes of recycled content and meet industry standards across various applications. Its relatively compact equipment footprint integrates an extensive set of advanced technologies and a conveyor belt, making it easy to install without additional, complicated material handling equipment. Operators also profit from TOMRA's proven track record and high safety standards. The AUTOSORT™ PULSE design protects workers from potentially harmful or penetrating light emissions.

Matthias Winkler, Product Manager at TOMRA Recycling Sorting, states:" We have a long-standing legacy in the metals segment, and our finger is on the market's pulse. Based on our extensive in-house knowledge, we started developing the dynamic LIBS technology when we sensed alloy separation could help businesses reduce downgrading material. After an extensive innovation phase, we have extended our product portfolio with AUTOSORT™ PULSE to complement the new generation X-TRACT™. Customers testing the machine are impressed by its results and its operational benefits. They can run high throughputs and create high-quality products, which gives them access to new material streams and benefits from operational flexibility and a quick return on investment. I strongly believe that AUTOSORT™ PULSE will solve the sorting challenges of tomorrow."

Data-driven results

The insights generated from sorting operation data are critical in facilitating plant operators' quest to run a profitable business with little to no downtime and maximum output. Available as an additional service for AUTOSORT™ PULSE, the cloud-based data platform TOMRA Insight allows for a data-driven optimization of sorting processes through near-live monitoring. As critical sorting data is available anywhere and anytime, operators can anticipate operational issues and future maintenance requirements and be in control of the entire sorting line.

Supporting net-zero

Aluminum is a very versatile material that is a highly demanded commodity for the transportation, building, construction, and packaging industries, contributing to an unprecedented demand for aluminium. In Europe alone, demand is expected to grow by 40 per cent from 2018-2050 with no signs of a trend reversal.1 At the same time, the aluminium industry is undertaking considerable decarbonization efforts to reach worldwide climate goals, such as those set in the EU and US for 2050.

To bridge the gap between supply and demand and support the transition to a climate-neutral society, the industry resorts to recycled aluminium which comes with a two-fold benefit: on the one hand, recycling aluminium is 95 per cent less energy-intense compared to primary production. On the other hand, it prolongs the lifecycle of already produced materials and gives new value to an abundance of scrap.

TOMRA’s extensive knowledge of metal recycling and sorting technology is unmatched regarding decarbonizing aluminium.

Terence Keyworth, the Segment Manager of Metals at TOMRA Recycling Sorting, states: “Our intensive and long-term collaboration with some of the world’s largest scrap recyclers and aluminium producers is the foundation of our development process. With AUTOSORT™ PULSE and our new generation X-TRACT™, we provide the technological force to drive the aluminium sector’s net-zero transition as it delivers high-quality alloy scrap fractions for producing low-carbon aluminium.”
