Abstract

Although membrane process is recognized as a green technology and is considered a key player in the process intensification movement, it is not widely known that fabrication of the membrane itself is far from green and is currently unsustainable. With the growing membrane market, more efforts must be placed on improving the sustainability of membrane fabrication such as replacing toxic organic solvents, minimizing mass intensity of fabrication process, and treating solvent-contaminated membrane wastewater. In this review, recent progress on improving the sustainability of membrane fabrication process is discussed. In particular, recently-identified green solvents are compiled, as well as novel methods to apply green solvents to fabricate high performance membranes. In addition, novel methods to minimize mass intensity of membrane preparation process, and to treat solvent-contaminated wastewater from membrane fabrication process, are discussed.
