Recycled Plastic Filter Stands Up to the Job

Oct-23-19 Molecular fibers made from plastic bottles could give waste plastic a new life as a strong and effective filter for the chemical industry.

Currently, the chemical industry relies on a heat-intensive process to separate chemicals—which can be hard on conventional filtration materials. As a more robust alternative, the team from KAUST created a filtering membrane made up of PET that has been dissolved and then stiffened to form the shape of a membrane. Adding poly(ethylene glycol) (PEG) to the material causes pores to form, which can be fine-tuned to control the filtration properties.
