POWERSORT 360 sorts plastics at 10 t/h
The new system separates different types of plastic – regardless of their color – with a throughput of up to 10 tons per hour. The main field of application is the processing of shredder fractions with a high percentage of black plastics. With POWERSORT 360 plastics can be detected in any stream. This ensures that mixed material streams can be split into fractions of ABS, PS, PC-ABS, PP, etc. or be cleaned of unwanted plastics such as PVC. Conta- minants such as wood, rubber, glass, stones and metal can also be separated. The black materials do not need to be separated from the colored materials and the material stream does not need to be presorted in any other way. Upstream regrinding of material is also eliminated. The system can process shredder fractions with grain sizes of 15 to 75 mm directly.

Unique sorting technology – laser spectroscopy

POWERSORT 360 analyzes material streams using laser spectroscopy. The detection system excites the molecules in the plastic parts with a powerfull laser light, analyzing the light spectrum that the individual parts then emit. Each material has a specific spectrum, i.e. a specific physical fingerprint, which acts as a unique identifier. The optical design with a powerful laser light source and an extremely high signal processing speed ensure that one million spectra can be generated and evaluated every second.

8 high performance sorters in one machine
The special geometry of the system combines eight high performance sorters in a single machine, which makes the best use of the laser system and the sensor technology. POWERSORT 360 consists of eight segments arranged in a circle. The high-energy laser system and the sensor system technology are located in the center of this circle. Together, the eight segments create an effective material scanning width of four meters. Up to eight different sorting tasks can take place simultaneously using these segments. To do this, the stream is guided over multiple segments in series. Alternatively, the plastic stream can run across all eight segments in parallel with a very high throughput up to 10 tons per hour.

High sorting quality and efficiency
Thanks to its compact, rotationally symmetric design the system has a small footprint of less than 20 sqm. Factors such as potential moisture, dust, different grain sizes, the varying material densities of one plastic type and colors have no influence on efficiency. The system offers excellent sorting quality and efficiency as well as a high throughput. It is highly configurable and can be adapted exactly to customer-specific sorting tasks.

Product category: Recycling plants for mixed waste, Separating and sorting systems for waste


A sorting system based on laser spectroscopy which separates previously inseparable plastics with highest precision and speed, allowing the long-term recovery of valuable raw materials.

POWERSORT 200 separates the following from a high- quality polymer product flow:
  • foreign polymers like PVC, Nylon, PC 
  • foreign materials like silicone, paper, glue residue, woods 
  • colored polymers/granulate 
  • Blends / Multilayer 
  • contaminated polymers
POWERSORT 200 uses a patented measuring procedure, based on high-speed laser spectroscopy. By referring to an impurity's spectrum, i.e. its physical "fingerprint", POWERSORT 200 is able to detect and separate it from the product flow. Up to 1,000,000 spectra are recorded and evaluated every second. Depending on the type of impurity, separation levels of 98% and above can be achieved – with a minimal loss of product. Unknown materials can also be separated using positive detection.
