The Région Grand Est has five large cities (Metz, Mulhouse, Nancy, Reims and Strasbourg) and borders with Germany, Belgium, Luxembourg and Switzerland. It is the second largest industrial region in France.

Seven regional or circular-oriented organisations decided to join forces in order to set up a useful tool, promote their circular initiatives and bolster their expertise in this field. The result was plateforme collectif-grandest.org, which aims to bring all stakeholders together to develop a circular economy in Grand Est businesses.

It is a resource centre, with publications and a directory of circular businesses and initiatives. Members can join or create communities and access support when setting up a project. The platform also holds annual meetings.
