K3® r100: RecyClass confirms plastic compatibility

With the adoption of the European Packaging and Packaging Waste Regulation (PPWR) in 2024, a major step was taken toward a more sustainable and circular economy. The regulation sets clear targets to promote circularity and improve plastic recycling across Europe. Companies are now required to design packaging that is recyclable, thereby contributing to a climate-neutral future. However, legal requirements alone are not enough - clear proof is needed that packaging can indeed be integrated into existing recycling systems.

Currently, there is no universally binding European guideline that precisely defines what “recyclable” means. For this reason, it is especially important for companies to rely on proven testing procedures that realistically reflect the recycling process. One of the most recognized institutions offering such validation is RecyClass.

Successful proof of recyclability

Last fall, Greiner Packaging achieved a major milestone: the K3® r100 cup demonstrated an outstanding separation rate of over 90%. Collection, transport, and sorting processes were simulated in collaboration with a certified RecyClass partner - and the results show that the cardboard wrap and plastic cup can effectively separate during the collection process. According to the PPWR, components must be evaluated separately if they detach from one another through mechanical stress during transport or sorting.

Due to this strong performance, Greiner Packaging was once again awarded a “Letter of Compatibility” (LoC) by RecyClass for the plastic component. This certification confirms that, thanks to the excellent self-separation of the cardboard and plastic, the plastic portion can be optimally integrated into the plastic recycling stream. Thanks to its excellent separability, the plastic component was awarded RecyClass’s top recyclability rating, Class A. The certification reinforces Greiner Packaging’s commitment to sustainable and environmentally friendly packaging solutions.

Almost like magic

Greiner Packaging has developed a solution in which cardboard wraps and plastic cups separate themselves from each other. This makes sorting of the materials and, in the next step, recycling much easier, which is why the packaging solution has been awarded excellent recyclability.

Reliable testing of recyclability

RecyClass is one of the leading institutions supporting companies in verifying the recyclability of their packaging. What sets RecyClass certification apart is its foundation in practical, real-world testing. This allows companies to gain a reliable assessment of how their packaging performs in actual recycling conditions.

These certifications serve not only as proof of recyclability but also offer guidance in meeting the expectations of consumers and regulatory authorities. They demonstrate that packaging meets the highest standards for recyclability and thus actively contributes to a functioning circular economy.

Looking ahead

The success of the K3® r100 cup’s separability is a significant step forward, but Greiner Packaging isn’t stopping here. Achieving a sustainable future requires continuous innovation. That’s why we are constantly working to optimize our packaging, guided by practical testing and the latest technologies. Our goal is not only to meet regulatory requirements but also to proactively support the transition toward a circular economy.
The compatibility certification for the plastic component of the K3® r100 cup represents a major step forward, and one that has the potential to positively influence future developments across the packaging industry.
