Abstract

The purpose of the research is to elaborate and implement a decision-making tool for greener membrane fabrication. The scientific novelty put forth in this study is the generic process modelling – LCA approach applied to the field. The resulting parameterized model allows to obtain material and energy flows as a function of operating conditions for ultrafiltration hollow fibers prepared by non-solvent induced phase separation. Its modular configuration allows for flexibility and adaptation to various membrane materials and industrial practices. Contributions of inputs on environmental impacts can be assessed, as well as the influence of operating conditions. Results for cellulose acetate membranes show major contributions of NMP (i.e. solvent) and glycerol (i.e. pre-conditioning liquid). Improvement strategies for environmental mitigation include acting on glycerol-related operating conditions and are to be considered within the geographic context of membrane fabrication; further technical and economic feasibility studies would embed these strategies in a full eco-design approach. Such a methodology and results should be taken into account for the elaboration of “green membranes” whatever the application and coupled with the impact of membrane use and end-of-life.
