Circular Berlin is an NGO that focuses on making Berlin circular. 

Berlin is envisioned as a resilient, citizen-oriented region where resources are sourced locally and their value is maintained as part of a continuous loop. Circular Berlin operates across areas such as community-building and education, as well as developing knowledge about industries with a high potential for circularity: the built environment, food and biomass, textiles and fashion, materials and products.

Circular Berlin hosts events where the community comes together to talk about key issues from sharing knowledge to collaborative planning sessions. Open-source digital tools enabling information to be exchanged more quickly have been built.
