From the Blue City website:
BlueCity is an incubator for circular entrepreneurs in and around Rotterdam. At this moment our hub (situated in a deserted swimming pool) and dynamic community (of entrepreneurs, researchers, neighbours, the government and education) serve as a breeding ground for 30+ innovative, circular companies linking their waste-streams. This way we create a much needed tangible and inspiring example for the circular economy, close the loops and build the city and economy of the future.
Our goal? To provide start-ups and scale-ups with access to circular resources, knowledge and talent, to turn ideas into action and ultimately: to help sustainable entrepreneurs to grow from intention to impact.
