The circular economy, a phrase meant to redefine economic growth beyond the current “take-make-waste” extractive industrial model, is gaining attention around the world as a way to produce more positive environmental and social benefits. Over the past few months, three cities have announced efforts to promote circular economy startups. In New York City, a contest will offer a $500,000 prize to the best idea and business plan that seeks to repurpose the city’s recyclables and manufacture a product to sell to the local market. The City of Phoenix and Arizona State University announced four companies will participate in an incubator affiliated with the Resource Innovation and Solutions Network (RISN). Last fall, public sector partners and the university-based Austin Technology Incubator (ATI) collaborated to launch a new Circular Economy Incubator in the region.
