Abstract
Membrane separations consume less than 90% of the energy required in incumbent industrial separation processes (absorption, distllation etc), and is widely considered as a "green" alternative for industrial separations. However, the manufacturing process of polymer membranes negates the "green" benefits of low energy. This is due to the mandatory use of oil-derived plastics and hazardous solvents e.g. NMP and n-hexane. At the Scale-Up Lab at The University of Edinburgh, we have deployed Green Chemistry concepts in tandem with additive manufacturing to imbue sustainability into polymer membrane fabrication. In this presentation, I will share with you key aspects of our work, including recycling plastic waste into high performance additives for mixed matrix membranes and replacing oil-derived plastics and overcoming the use of hazardous solvents in thin-film composite membrane fabrication.
