The Dynamic LIBS solution for sorting metals by alloy and grade
Advanced Dynamic LIBS technology for high-value metal sorting
AUTOSORT™ PULSE classifies complex material streams by alloy, grade and composition, enabling high-throughput production of higher-value metal fractions. Dynamic laser-induced breakdown spectroscopy (Dynamic LIBS) technology offers flexible scanning modes for higher precision sorting and long-term operational flexibility across different material streams.
Thanks to the machine’s bulk infeed system and powerful combination of sensors, it offers high-throughput sorting across the full belt width without requiring material to be fed into fixed tracks. Dynamic LIBS technology supports high-quality sorting with less material preparation, even with painted, coated or dirty material. This flexibility allows operators to process aluminum alloys one day and a different valuable metal fraction the next, depending on input material, customer demand or production priorities.
Operators can also benefit from access to critical sorting data for greater visibility into machine performance, material trends and sorting results. With its high safety standards, compact footprint and easy integration into new or existing production facilities, AUTOSORT™ PULSE helps operators go deeper into complex material streams and unlock value that would otherwise be downgraded or lost.

What can AUTOSORT™ PULSE sort?
Aluminum alloys
Classifies aluminum scrap by alloy series, such as 6063, from post-consumer or incinerated bottom ash streams, enabling higher-value fractions for direct remelting without downgrading valuable material.
Stainless steel grades
Separates mixed stainless steel by grade, such as 316, 304 and 201, enabling higher-value stainless fractions and stronger control over material composition for downstream recycling and remelting.
IBA metals
Recovers valuable metals from incinerated bottom ash streams by classifying aluminum alloys and recovering copper and brass from IBA mixed heavies, enabling more value from complex ash-derived material.
Mixed heavies
Upgrades mixed heavies by separating higher-value fractions such as copper, brass, zinc, stainless steel and zinc sheets from Zamak, enabling recyclers to capture more value from complex heavy metal streams.
Coated and non-coated materials
Separates coated and non-coated metals by analyzing beyond the surface layer, enabling higher-quality fractions where paint, coating, dirt or other surface conditions can affect material value or downstream quality.
Magnesium
Sorts magnesium from floated super light fractions and other relevant streams, enabling additional recovery opportunities where magnesium separation is important for material quality and value.
What makes AUTOSORT™ PULSE different?
Dynamic LIBS technology
Unlike static laser systems, AUTOSORT™ PULSE uses four dynamic lasers to scan the entire belt. Dynamic LIBS technology classifies complex metal streams by alloy, grade and composition, while deeper composition analysis can solve sorting tasks that are difficult or not possible with XRF and other technologies. • Multi and single-point flexibility • Alloy, grade and composition-based classification
Premium engineering for better value
Competitors may rely on 10–20 static lasers. AUTOSORT™ PULSE uses only four. Fewer laser components can reduce maintenance requirements and support longer component life, helping lower total cost of ownership over time. • Lower maintenance requirements • Reduced risk of failures • Lower total cost of ownership
Industrial-scale sorting without fixed tracks
The bulk infeed system enables high-throughput metal sorting across the full belt width without requiring material to be fed into fixed tracks. The system supports industrial-scale performance with less dependency on grain size and material preparation. • 250 objects processed per second • Up to 15 t/h throughput on a 1.2 m belt • 10–150 mm grain size range for unmatched flexibility
Reliable detection in real-world bulk streams
In bulk material streams, objects can overlap, touch or sit close together on the belt. AI-based object singulation helps identify adjacent and overlapping objects, supporting reliable classification and precise ejection. • Detection of overlapping and adjacent objects • Reliable sorting in complex material streams • Precise object tracking and ejection
One platform for changing metal sorting tasks
AUTOSORT™ PULSE gives operators the flexibility to switch between high-value metal sorting tasks as material streams, customer demand or production priorities change. Flexible scanning modes help adapt the Dynamic LIBS system to different applications and material conditions, including painted, coated or dirty material. • Use across different metal streams • Higher machine utilization • Different scanning modes for changing material requirements
Greater visibility into sorting performance, trends and results
Access to critical sorting data gives operators greater visibility into machine performance, material trends and sorting results. This supports stable operation, faster adaptation and data-driven process optimization over time. • Visibility into machine performance • Material trend and result tracking • Support for process optimization
Gerhard Lang Recycling GmbH has made history by becoming one of the first companies globally to implement TOMRA Recycling’s AUTOSORT™ PULSE system for the precision sorting of aluminum alloy stamping scrap generated from automotive production in early 2024.
Raffineria Metalli Cusiana S.p.a. (Cusiana), a major Italian secondary aluminum refiner supplying multinational automotive, construction and furniture companies across Europe, has established a strategic partnership with TOMRA Recycling to redefine aluminum recycling with advanced multi-sensor sorting technology.
