for recognition of materials according to their chemical composition


The performance of REDWAVE XRF/C technology is excellent, and it was absolutely the right decision to choose REDWAVE for our metal recycling plant. REDWAVE is a very experienced partner! CFO has searched for solutions to separate metals for a few years. REDWAVE convinced us it was the only complete solution for our process, and that was the reason why we choose REDWAVE. With the XRF technology, it is possible to achieve far more and to increase the value of scrap metals in Europe. It was a pleasure to work with REDWAVE’s team; their knowledge and availability were quite important to our project.

Innovative belt system designed specifically for fine materials

REDWAVE Belt systemVSChute system
Optimal for small and rolling parts (from 4 to 25 mm) Optimal for large parts (from(10) 15 to 180 mm)
Uniform conveyance prevents changes in speed or position of the parts, allowing for accurate sorting. Controlling the slippage of small parts is challenging. Frequent changes in speed and position can reduce the quality of the final product or output rate.
The new and innovative REDWAVE belt prevents material from snagging.  Due to humidity and dirt fine materials may stick to the chute.
The trajectory is controllable and remains constant, which ensures accurate sorting. The trajectory of small materials changes and is unpredictable making precise sorting difficult.
Highest precision and performance for sorting fine, small, and round parts Highest precision and performance for sorting coarse material. 



For metal sorting

  • One machine is all you need – for any application
  • Sorting of all kinds of non-ferrous metals such as ZORBA, TWITCH, ZURIK, IBA and heavy metals
  • Highest efficiency and purity due to innovative free-fall design, combination of XRF and camera and the state-of-the-art software algorithm
    - Versatile and flexible
    - Quick reaction to market change
    - ROI usually in less than 1-2 years
  • Highest efficiency and purity due to
    - Innovative free-fall design
    - Combination of XRF and camera
    - Most state-of-the-art software algorithm


  • Small footprint of only 11m² allows for easy integration
  • Same chassis size for each sorting width
  • Pioneer and leader in XRF based sorting machines with +15 years of experience
  • More than 150 XRF-machines in operation worldwide
  • Expert in sorting non-ferrous metals


For glass sorting

  • Separation of glass ceramic and lead-containing glass in one process step
  • Sorting efficiency is not impaired by the color of the broken glass, dirt, moisture, labels high throughput
  • Accurate detection of the elements thus no misinterpretations as with other technologies (e.g. fluorescence effect caused by other non-Pb-containing UV detection of Pb-glass)
    - Easily adjustable for future heavy metals in glass
    - Ordinary glass is not detected
    - Therefore no false detections


  • Only one machine for lead glass and glass ceramics
  • Either as first or last sorting stage
  • Consistent high removal of lead glass and glass ceramic
  • Pioneer and leader in XRF-based sorting machines with +15 years of experience
