Facing the global climate change and resource exhaustion, the so-called “Circular Economy” (CE) has become a solution for sustaining the global ecological system and developing industrial innovation all over the world. Circular Economy is a system of resource re-uses among different industry sectors. It is also one of our pioneer plans proposed by the government. However, up to now, there is no systematic and analytical approach to determine both the kinds of industries included in a CE and their operations. Therefore, it is the aim of this sub-project to support a government policy making on identifying the most effective industries for cooperation on resources re-utilization based on the industry correlation intensity so that the re-used rate would be maximized and the value added will be lifted up. To verify the derived correlation matrix, a case of Food/Energy/Water nexus in Taiwan is performed to provide policy makers the long term evaluation of the FEW system on the social, economic and environmental impacts.
