Batteries and Vehicles

I encountered the concept of circular economy during my master’s studies at TU Munich, where I studied business administration. I was fascinated by the idea to keep resources in different cycles trying to decouple economic growth from resource use. So, I joined the sustainability consultancy SYSTEMIQ and worked on various issues related to circularity. At CIRCULAR REPUBLIC, I now work as an operations and project manager, developing circular solutions for the future battery value chain together with our partners.

Nearly a decade ago I founded my first venture with one of the first sustainable footwear companies. Sustainable designs developed towards recyclable products and new ventures in the recycling industry followed. Once I realized that circularity cannot be achieved by one stakeholder in the value chain, I started developing a multi-stakeholder approach turning linear industries towards circularity. CIRCULAR REPUBLIC and UnternehmerTUM are the ideal ecosystem to build such multi-stakeholder platforms.
