The Ambit B30 Association works to consolidate, grow and promote the B30 axis, a geographical area within the metropolitan region of Barcelona of great economic and industrial vitality, with a wealth of knowledge and innovative capacity. One of their main objectives is to support the circular economy as a means for change and economic and social progress. Since 2017, they have commissioned several projects aimed at implementing circular economy solutions at a local level. One of the lighthouse projects was the B30 Circle Scan: an analysis of the potential of the circular economy in the region. The Scan defined a roadmap, identifying the opportunities and starting points for fostering the circular transition.
