英文摘要	Based on a comprehensive review of previous renewability assessment studies, the present work contributes a framework to assess the renewability of a production system based on the systems ecological concept of embodied energy as emergy (embodied solar energy). An input-output analysis based transformity database is adopted to concretely trace the renewable and nonrenewable resources embodied in the supply chain for all product materials. A renewability index as the percentage of total renewable resources over the total resources used for the production process is devised to assess the renewability of a production system. The renewability assessment of a typical wastewater treatment system in Beijing is performed as a case study to illustrate the framework in context of water-energy nexus. The renewability index of the case system is evaluated around 13%, and fossil energy is revealed as a key source for total resources use. The presented framework is shown to have broad application prospects and can be very useful in sustainability studies. (C) 2015 Elsevier Ltd.
