K 2025, the most relevant trade fair for the plastics and rubber industry worldwide, drew to a successful close on 15 October 2025 after 8 days. In view of the current difficult economic climate, many companies in the plastics and rubber industry travelled to Düsseldorf with rather subdued expectations. But the mood prevailing across the fully occupied exhibition grounds proved outstanding on all trade fair days. The plastics and rubber industry presented itself as more innovative, international and determined than ever to actively shape the transition to more sustainability, digitalisation and social responsibility.
