Linking the Loop: A Social Network Theory Perspective on the Role of Circularity Brokers for the Circular Economy

Circularity brokers are intermediaries fostering the exchange of circular flows and represent a critical yet underexplored aspect of circular economy. Through social network theory, this paper examines how circularity brokers support creating circular supply chains. Using qualitative meta-analysis, the study examines 68 circular economy projects across sectors involving circularity brokers. The analysis enables investigating the actor playing the role of the circularity broker, its strategic orientation, and performed functions, along with the network structure and scope. Findings are summarized in nine propositions, highlighting how circularity brokers play a crucial role in fostering circularity, driven by their knowledge of circular economy and ability to offer tailor-made services. Circularity brokers strategically orchestrate circular economy networks to either exploit circular flows and establish a business or develop connections among participating nodes, thereby fostering circular ecosystems. The clear identification of the role of circularity brokers can promote their diffusion, ultimately supporting circularity.
