K2025 | EXHIBITION PREVIEW


where sensor and magnetic technology is used on an industrial scale to sort pre-sorted packaging materials into recyclable plastics. Tours can be booked on Steinert’s website. � www.steinert.de


WIS Kunststoffe will present several certified recyclates for food use, which were developed through technical collaboration. A highlight of the show is a new process for making food-grade polypropylene (PP) recyclate from post-consumer food packaging. In collabora- tion with KraussMaffei Extrusion, WIS has devel- oped the scalable process that has already re- ceived FDA approval for food-contact applications. “The combination of process know-how,


state-of-the-art equipment, and close collaboration was key to this,” said Daniel Römhild, head of development at WIS. A twin-screw extruder used in the process enables gentle processing and ensures high-quality recyclate output. The process can be integrated into existing workflows and creates opportunities for post-consumer recycling in the food sector, it says. David Rapp, team leader for process engineer-

ing recycling at KraussMaffei Extrusion, added: “Our ZE BluePower twin-screw extruder offers gentle, efficient material processing – a critical factor for recyclate quality.” WIS Kunststoffe’s portfolio also includes regran-


ulates based on PP and PE that are heat-resistant, odour-optimised, and colourable. These meet the demands of various industries, including cosmet- ics, packaging, automotive and toys, it says.
