The chemical industry can contribute to the global sustainability by integration of evaluation of environmental impact with product and process design activities. We constructed an activity model to incorporate life cycle assessment (LCA) into the early phase of chemical process design. We showed that the selection of reaction, process and life cycle strongly relates each other, and proposed a methodology for the selection of chemical process from the view point of environmental impact by performing a case study, in which a chemical recycling process of PET resin is selected. An integrated information infrastructure, which is constructed by the hierarchical models of reaction, unit operation, process and life cycle, is needed for the design of chemical products and processes based on LCA.
