K 2019, the largest global trade fair for the plastics and rubber industry, which hosted more than 3,300 exhibitors from over 60 nations and approximately 225,000 attendees, drew to a close in Düsseldorf, Germany after eight days on Wednesday 23 October. According to a press release issued by show organizers following the event, this year's K highlighted the necessity of having operational circular economies along the complete plastics industry material chain, and visitors this year took great interest especially in recycling systems, sustainable raw materials and resource-saving processes.

"K 2019 came at precisely the right point in time," said Werner Matthias Dornscheidt, President & CEO of Messe Düsseldorf. "There is no other place the industry is represented so internationally and completely as here in Düsseldorf every three years. Especially in times of great challenges, a platform like the K is indispensable. It provides guidance and perspectives, sets sustainable economic impulses, shows forward-looking trends and concrete approaches. The industry and its professional associations enjoyed the unique opportunity here to present sector-specific solutions and debate questions of socio-political relevance on a global scale."

Ulrich Reifenhäuser, chairman of the Exhibitor Advisory Board at K 2019, commented: "The plastics and rubber industry succeeded in proving once again that plastics are not only very valuable materials with outstanding properties but also that this industry assumes responsibility along the entire value chain."

"Never before has the industry addressed an issue so unanimously and worked on solutions so consistently as is the case now in the fields of environmental compatibility, saving resources and avoiding waste. There is a spirit of new departures prevailing in the industry and current dynamics are overwhelming."

When recycling polyamides, Brüggemann's BRUGGOLEN M series of reactive chain modifiers allow precise and reproducible adjustment of relative viscosities, by either lengthening excessively short chains or shortening those which are too long. Producers can use small amounts of these modifiers to tailor relative viscosities to their needs in a single compounding step. The resultant upcycled materials exhibit excellent mechanical properties and are suitable for the same applications as prime materials of similar viscosities. This removes the need to blend the recyclate with prime polymers and opens up a wide range of possibilities for establishing a profitable market for secondary polyamide raw materials which meet the high-quality requirements of the molding industry.

Ulsan, South Korea-based Songwon Industrial Co., Ltd., the 2nd largest manufacturer of polymer stabilizers in the world and a key global specialty chemicals player showcased its sustainable solutions and highlighting its focus on sustainability and positioning as an enabler of circularity during K2019. SONGWON's range of polymer stabilizers prolongs the lifetime of polymers, contributes to making materials reusable and stabilizes the polymer through the mechanical recycling step.
