The OCCE is a Brussels-based federation that provides support for European investors, territories and innovators in the field of circular economy.

For investors, the OCCE can provide a link between investors/investment companies and the EU/EIB with a view to accessing funding. For territories, the OCCE supports regions, communities and local actors in becoming promoters of innovation, which can then be transformed into CE investments, jobs and industrial success stories. For SMEs, start-ups and project leaders, it can provide support and knowledge, primarily with regard to the EU's financial support mechanisms. And for its members, by sharing its international networks, the OCCE allows them to integrate an international dimension into their projects.
