Austrian recycling specialist Next Generation Recycling Machines (NGR), in partnership with German extrusion machinery supplier Kuhne GmbH, have unveiled a new liquid state polycondensation (LSP) technology for PET recycling and extrusion.
In an open day on 8 Nov at its Feldkirchen, Upper Austrian production facility NGR demonstrated the new recycling process, which it claims has overcome limitations in other processes.
The LSP technology, involves decontamination and rebuilding of the molecular chain structure in the liquid phase of the PET, allowing recyclers more flexibility with regards to the input materials.
The process, which is claimed by NGR to produce food-grade materials, can mix and recycle different forms of PET waste, from bottle flake to scrap fibre, sheet, thermoform waste, strapping, and other lower value scrap streams.
Furthermore, NGR claims that its new technology can be used to easily process co-polymer forms of PET (PET-G) and polyolefin contents.
