XRF Technology for a Better Metal Sorting
Redwave, the center of excellence for recycling and sorting technologies within Austria-based BT-Systems GmbH, offers a new solution for the metal recycling industry with its latest generation of REDWAVE XRF sorting machines.
By integrating the spectral analysis technology into this sorting system, the company is unlocking new opportunities for metal recycling, particularly in aluminum recovery, the provider is convinced. “This system enhancement now enables the processing of a wide range of material streams, including Zorba, e-scrap, used beverage cans (UBCs), IBA, and mixed metal fractions, while ensuring the accurate identification of aluminum alloys with high purity and quality.”
Flexibility and cost-effectiveness
BT-Systems GmbH’s REDWAVE XRF sorting machines have long been used successfully for separating aluminum and heavy metals such as copper, zinc, brass and lead, the company gave account. “Until now, aluminum could only be separated based on accompanying elements like copper or zinc, making the precise identification and sorting of various aluminum alloys challenging. These technological limitations are now a thing of the past.” By combining spectral analysis with XRF fluorescence technology in one Redwave sorting system, a broader spectrum of material composition could now be analyzed. “Compared to other technologies, this system is equally effective with materials that have contaminated surfaces, making it suitable for nearly all materials,” the company emphasized. “This advancement opens up entirely new possibilities in aluminum separation and significantly improves material purity and recycling quality.”
