Knowledge
We compile much of what matters in the field of circularity and plastics in this CPNL Knowledge Hub: observations, research, white papers, book recommendations, fact sheets, podcasts, and best practices. This Knowledge Hub is so rich and comprehensive because we don’t just fill it ourselves—we do it together with our community. It’s a virtual hub where authors are acknowledged and credits and sources are kept where they belong. Recommendations and suggestions are always welcome.
