Abstract: Life-Cycle Analysis (LCA) is used to understand the holistic flow of energy and materials throughout a product|s life. As part of a comprehensive approach to design next-generation dialysers, we performed a LCA of an Optiflux F180NR dialyser. Combining LCA insights with a functional analysis of each product component, we analysed which components could be improved most effectively. Determining that the polycarbonate housing was the optimal area of focus, we used SolidWorks and COSMOSWorks to test, in-silico, the strength of various reduced-weight housing designs. The final design weighed 17% less than the original without a significant loss in strength.

Keywords: LCA; life cycle analysis; sustainable design; peak oil; dialyser design; dialysis; single-use; disposable; medical devices; product design; functional analysis; polycarbonate housing design.
