Making the impossible possible: Recycling multilayer packaging

13/09/2023

Was multilayer packaging the Achilles' heel of the recycling industry? Not anymore, according to Krones and their project partners BASF, Südpack, and Tomra. Together, they're unveiling a solution that accomplishes what was once deemed impossible. At the heart of this innovation is a new adhesive that enables effective material separation during the recycling process.

Bend it like PU – Plastics in sport

30/11/2022

Today, no one can imagine leather balls, wooden rackets, bamboo poles or cinder tracks in sporting competition. Natural materials have now been almost completely replaced by other materials: plastics. They are light, robust and highly functional. Thanks to intensive research, they are also becoming more and more efficient – and ultimately lead to new world records.
