Greiner AG


For more than 150 years, Greiner is one of the world’s leading suppliers of plastics and foam solutions. So that it stays that way, Greiner Technology & Innovation, the group’s innovation center, has developed the organizational framework for a holistic innovation strategy and has defined the stages from a very fuzzy front end to integration into the group.


cicrle17 managed to provide a robust innovation and idea process, which allowed us to quickly jump into the topic and start working together with the team on our Challenge. Overall the tools and preparation for the virtual collaboration was excellent.

What Challenge were you working on during your time with circle17 and what SDGs are you focusing on?

Our challenge was “How might we develop the first 100 % sustainable mattress?” which also addresses the following SDGs: (3) Good Health and Well-Being; (9) Industry, Innovation and Infrastructure; (12) Responsible Consumption and Production; (13) Climate Action.

What did you learn from your experience?

Engaging with inspiring people in common challenges is not the only way to push the envelope towards sustainability and radical innovation. However, this hackathon concept developed by circle17 is an auspicious way to drive innovation in the paradigm of open innovation. In terms of methods and processes, we were able to experience a very well-designed workshop.

How was it working with start-ups?

The collaboration with the start-up was great, and we seek further cooperation in terms of implementing this idea. We are delighted to work together with this great team, and we are looking forward to working on the shared vision.

Did you set up a partnership and if so, would you like to tell us more about it?

Currently, we are in the process of setting up a partnership. However, the details are not defined yet. Nevertheless, we have a top-management commitment to work on this project. Within this project, there will be much more potential partnership with other exciting companies which try to make the mattress industry more sustainable.

What would you recommend future participants to get the most out of the experience?

Be open-minded and trust the competent team of circle17. Use enough resources – primarily time and effort – to engage with the team and build a long-term relationship with the team beyond the engagement within the context of circle17.
