==== Applications: ====
'''PET bottle recycling'''
* The multi-sensor sorting system ''Varisort'' is used to automatically separate impurities from PET-Bottle streams. The Varisort series is based on a modular concept in which up to three sensors can be combined
*  The metal separation system ''Varisort M'' automatically removes metal particles from the PET-Bottle stream
* The contaminant separator ''Varisort N'' separates different types of plastics from the PET-Bottle stream
* The foreign colour separator ''Varisort C'' is used to separate differently coloured PET-Bottle streams into pure colour fractions.
PET flake recycling
The multi-sensor sorting system ''Flake Purifier'' is used to automatically separate impurities from PET-Flake streams. The Flake Purifier C series is based on a modular concept in which up to three sensors can be combined:
* The metal separation system ''Flake Purifier M'' automatically removes metal particles from the PET-Flake stream.
* The contaminant separator ''Flake Purifier N'' separates different types of plastics from the PET-Flake stream.
* The foreign colour separator ''Flake Purifier C'' is used to separate differently coloured PET-Flake streams into pure colour fractions.
