Huge sizes. Enormous benefits.


Excellent decontamination efficiency and fast iV increase

Increasing demands for recycled PET boost the trend for bigger plant sizes, especially in bottle-to-bottle recycling. viscotec has introduced viscoSTAR 250 and viscoSTAR 350 to ensure high productivity thanks to high throughput rates for efficient and safe bottle recycling.

viscoSTAR solid state polycondensation plants stand for fast increase of intrinsic viscosity (iV) and efficient decontamination of polyester pellets. Our customers use viscoSTAR plants after pelletizing extruders or as stand-alone solutions to produce recycled PET in food-grade quality according to EFSA, FDA and brand owner approvals. Frequent long-term gas chromatographies at customers’ installations worldwide confirm perfect cleaning efficiencies.
