| Abstract | Urban areas with large population and economic activity are responsible for the increased resource and environmental challenges, making circular economy an important issue. Sustainable development and targeted suggestions for local areas are essential for policy implementation. In this study, a circular urban metabolism (CUM) framework was developed to assess resource use patterns for potential identification and policy initiatives of circular development. The framework was conceived as a circular process for sectoral material flow mechanisms, which was followed by resource use calculations and circularity potential analysis. In the Shanghai case, the CUM framework was testified and revealed dramatic increases of material inputs and outputs, doubled during 2000-2019. Close relationship with external areas was indicated by large resource consumption and pollution discharge. Specified by CUM, the expanded in-use stock, mainly consisted of non-metallic minerals used in construction sector, were one of the obstacles towards circularity. Energy-induced pollution was the other obstacle, which were suggested by mixed energy use initiatives. Sectoral policy to improve resource use patterns were finally provided at the city level. |
