Title: Framework for Sustainability Metrics
Issue Date: 2007
Abstract: This work presents the application of a new framework for sustainability metrics to industrial processes, inparticular, to chemical processes. The sustainability of an industrial process can be evaluated using a set ofthree-dimensional (3D) indicators that represent all three dimensions of sustainability: economic, environmental,and societal. The four 3D metrics proposed in this worksnamely, material intensity, energy intensity, potentialchemical risk, and potential environmental impactsare applicable to a wide range of process systems. Thefirst two metrics are associated with the process operation. The remaining two metrics, potential chemicalrisk and potential environmental impact, respectively represent chemical risk to human health in the processenvironment, and the potential environmental impact of the process on the surrounding environment. Toillustrate this framework and the applicability of the proposed set of 3D metrics, two case studies arepresented: chlorine production process using three different alternatives (membrane, diaphragm, and mercurycells), and the separation of an acetone/chloroform mixture by two different solvents (benzene and methyln-pentyl-ether). Results of this study show that this framework can be effective in selecting the more-sustainableprocess by comparing process alternatives.
