As part of the Circular City Challenge, the cities of Berlin, Munich, Stuttgart, Vienna, Hamburg, Detmold and the municipalities of Zeuthen and Ortenau joined forces in 2023 and launched a call for innovative solutions in the field of municipal circular economy. The aim of the challenge was to bring together local authorities with innovators and start-ups to jointly develop and implement circular solutions. The project was funded by the Stuttgart Innovation Fund.

Creative Climate Cities (CCC), in collaboration with Circular Berlin, Circular Munich, Materialkreislauf, Circonnact and Fab City Hamburg, supported the implementation of the Circular City Challenge 2023 and provided special support to the municipalities of Leipzig and Zeuthen. We took on the role of active matchmaker: we provided strategic support to the municipalities throughout all phases of the process – from the identification of specific challenges and the targeted tendering of suitable solutions to the curated selection and placement of appropriate providers from our extensive network.

Through close support throughout the process, we initiated tailor-made collaborations between municipalities and innovators, laying the foundation for the first steps towards implementation in the field of circular economy.
