Circular Economy Fellow at WRI, Mathy Stanislaus, is exploring, "what are the key levers, specifically policy levers, to accelerate the circular economy?" He's found some key points: value retention processes (extending life and enabling second life of products) and creating and optimizing a secondary materials system (a market for using used materials in safe, healthy and effective manners). Doing so can reduce new resource extraction by 80 percent and GHG impacts by 80-90 percent. The incentives are high — and so prioritization is imperative.
