Circular Challenge, Citeo’s Open Innovation programme

In 5 years, Circular Challenge has succeeding in building a programme that clearly demonstrates how it can identify and support innovative and concrete solutions, both in France and abroad, and foster a real ecosystem of committed players. Detection, Experimentation, Acceleration are the three pillars of a comprehensive programme dedicated to promoting the transition towards a circular economy. 

Open Innovation aims to combine "thinking" and "doing" to successfully build the transition together with our customers, and local communities, operators, manufacturers, non-profits, designers and entrepreneurs.


Innovation emerges at the crossroads where different functions, players and sectors converge.

Circular Challenge's actions are routed in open innovation. Co-construction and interdisciplinarity are the main features of a range of projects and initiatives which, thanks to design methodologies, offer concrete and immediate solutions.

Based on a broad ecosystem of entrepreneurs, innovators, investors, companies, manufacturers and communities, Open Innovation aims to enable the acceleration and deployment of relevant solutions and thereby contribute to the transition to a circular economy.
