Proposed Framework for Assessing the Sustainability of Membrane Life Cycle

Developments in sustainability assessment tools are leading to an increased interest in sustainability assessment for products and services. Several sustainability measurement tools and frameworks have been developed. However, most of these tools only focus on environmental considerations while some of the frameworks only focus on governmental progress. In this paper, a comprehensive framework for assessing sustainability is presented. During framework development, the Life Cycle Assessment (LCA) and fuzzy logic approach was applied. LCA determined the sustainability parameters and estimated the potential environmental impact from the membrane product. Next, the fuzzy logic approach was applied to deal with the qualitative and quantitative data. The proposed framework focuses on the evaluation of membrane products. However, the proposed framework can be adopted for other related products.
