The German recycling company STF Group already runs three solid-state polycondensation (SSP) plants from Starlinger at their recycling venues. In the recycling industry, the STF Group is known as one of the leading European recycling firms. Lately, the fourth and even bigger “viscoSTAR” has been installed to further increase their capacity to produce high-quality rPET granulate.
More capacity at better quality
The new SSP plant is used after an existing recycling pelletizing extruder to enhance the quality of the PET pellets. The decision to spend 1.5 million euros to upgrade their plant makes perfect sense for STF Group in two respects. By installing the viscoSTAR plant, STF invested in technology which they know and trust in. Perhaps more importantly, the installation allows producing more at the same time with superior results. “Our renown customers in the food industry worldwide appreciate the high quality of our rPET resin”, outlines Stephan Gschwendtner, the production manager.
