Texte AlternatifThe main challenge is to manufacture recyclates to a sufficient level of quality allowing them to be reused for the production of high-quality packaging. The majority of recyclates are not yet suitable for use in packaging and are thus removed from the packaging cycle. Printing inks play a key role in the manufacture of plastic packaging. They are not only crucial for the appearance and functionality of the packaging, but also for its recyclability.

“Printing inks in particular, but also pigments, and the organic residues from post-consumer waste, represent a challenge when it comes to manufacturing a reusable recyclate that is as versatile as possible”, explains Klaus Wohnig, spokesman at APK board. With Newcycling®, APK has developed a solvent process that dissolves and cleans the polymer, meaning that polymers can be separated selectively in mixed plastic waste. The result is sorted granulate that is like new.

As a specialist in packaging printing inks, Siegwerk has strives to constantly improve the ecological footprint of its printing inks and varnishes while actively shaping the future of packaging with innovative and sustainable ink solutions. Siegwerk is already pursuing different approaches for removing printing ink (de-inking) in various recycling processes in order to improve recycling quality. With this collaboration, both companies see the possibility to jointly meet the challenges in plastic recycling, to make plastic packaging more circular and consequently to perfect it for a sustainable future.
