We’ve done a lot of research and careful thinking about the best material for our containers.
In this case, it’s not just about environmental factors – safety for children is our top priority.
This is exactly why we avoid using recycled plastics. They can be contaminated with substances such as BPA and other plasticizers, which may transfer to the product. Glass would be an alternative, but due to safety concerns and transport challenges, it is not a practical option. Biodegradable plastics also do not currently offer a truly satisfying solution for our products. Starch-based plastics decompose too quickly and are not suitable for moist and long-lasting items like ours. PLA-based materials fall into recycling class 07 (Other), which is difficult to recycle and must be processed together with other plastics according to German regulations. Another bioplastic, so-called bio-polyethylene or Green PE, raises many ethical and environmental concerns regarding the sourcing of raw materials. These often come from intensive agriculture and may contribute to deforestation and human rights violations.
For these reasons, we believe that responsible recycling – at least during the current stage of development of safe, biodegradable plastics – has a far more positive impact on our environment and the actions of future generations.
After all, only a mindful approach to all types of plastics can sustainably protect our living environment.
That’s how we came to the decision that the currently best solution for our cup material is BPA-free, food-grade polypropylene (PP). This material is pure, safe, and up to 100% recyclable – meaning it can become a new product again.
Upcycling before recycling! You can also simply reuse our cups — as containers for pens and other small items, or even as flower pots.
That way, you can watch not only the plant grow, but also its roots. You’ll find some ideas on our blog.
Please dispose of plastic responsibly and only according to your country’s local recycling guidelines. Thank you!
