Switzerland-based Poly Recycling, a division of Signode Industrial Group, has achieved full return on investment in six months following the installation of Bühler’s optical sorting station.
The system integrates separation and sorting steps in the processing line, and includes plant engineering, sorting technology, mechanical separation machinery, pneumatic conveyors, pre-conditioners and auxiliary equipment.
Poly Recycling sought Bühler’s help to increase the capacity and quality of its rPET flake sort at its Swiss facility. It is now sorting more than three tonnes an hour, and is enhancing its capabilities to overcome PVC contamination from labels using newly developed PVC label reductions kits.
Three years on, the company has significantly expanded its business by providing its high-quality plastics flakes to a wide range of new sectors.
Casper van de Dungen, managing director of Poly Recycling and vice-president of Plastics Recyclers Europe, said: “We have not only been able to improve the quality of our plastic flakes but have reduced the wastage of good product during processing.”
