To mark its 40th anniversary, the family-owned company Gneuss from Bad Oeynhausen presented exciting new products and innovative recycling technologies during a two-day technology event on 7-8 November 2023. Visitors from five different continents took part and experienced first-hand presentations of the extrusion systems MRS, MRSpure and MDS, as well as the recycling systems OMNImax and OMNIboost and various melt filtration systems. The CEO brothers Dr. Stephan Gneuss and Daniel Gneuss opened the event in the recently built 2700 m² production hall, which had been specially redesigned for the event, and gave an introduction to the technological innovations of the following presentations. The department heads from the Fibre & Pellets, Film & Sheet and R&D divisions provided insights into the key characteristics and applications of the new OMNI recycling technologies. Interactive survey elements during the presentations encouraged a lively exchange of ideas and perspectives on plastics recycling among the participants. In Gneuss Technical Centre 1 at the main site, the focus was on processing PET and PS regrind into food-grade thermoforming sheet on an OMNImax recycling line. The trials in Technical Centre 2, on the other hand, concentrated on the regranulation of PET fibres using the OMNIboost recycling system and the closed-loop recycling of HDPE bottle caps with the MRSpure extruder. A highlight on the evening of the first day was a gala dinner in the historic Kaiserpalais, which was held to celebrate Gneuss’ 40th anniversary. Here, company founder Detlef Gneuss not only looked back on the past of his family-run company, Dr Stephan Gneuss also gave an outlook on the coming years and the continuation of the Gneuss success story. The event was a great success and once again demonstrated the innovative strength and technological expertise of the East Westphalian company. The international participation and consistently positive reactions of the visitors emphasised the strong interest in sustainable technologies. A look into the future promises further pioneering progress in the field of recycling and sustainable production processes.
