Decontaminate high viscosity materials fast and efficiently with the new melt phase decontamination reactor.

Designed to produce recycled food grade resins from polyolefins and polystyrene or food grade, iV-increased recycled PET. Available as turn-key solution or as upgrade for your existing recycling extruder. 


ZERO contamination
Post-consumer recycled materials safe for direct food contact. Thanks to efficient decontamination and homogenisation of the material.


ZERO waste
Zero waste achieved through 100% recycling rate. viscoZERO recycles different types of high viscosity input materials.


ZERO odour
Efficient removal of high and low volatile odours. Results in pure and odour-less recyclate for demanding applications and packaging solutions.


ZERO limits
Zero limits for new business opportunities. Flexibility to process a wide range of input materials into resins of outstanding quality.

viscoZERO benefits:

  • Superclean post-consumer PP, PE, PS and PET
  • iV increase for PET
  • Odour removal
  • Spin finish removal
