Supply Value has conducted research into the implementation of circularity within leading companies in collaboration with Tilburg University. We are in interviewed twelve leading companies from five different industries, both public and private. Of the results we answer three questions:

1. What is the rationale for implementing circularity within organisations?
2. What are barriers to implementation of circularity in organizations?
3. What are success factors for the implementation of circularity and what tools do they offer?

The results show that organizations mainly implement circularity for ecological and economic reasons. The five most urgent barriers to implementing circularity are adjusting the organizational structure, setting up efficient return flows and cascades, consumer awareness and interest, the price of virgin materials and legislation and regulations. The five most important success factors for implementing circularity are circular product design, chain collaboration, creating internal support, making circular initiatives measurable and stimulating legislation and regulations. The Circular Value Model offers guidance for organizations with the intention of implementing circularity.
