Sound waves used to separate microplastics from laundry wastewater

Sound waves used to separate microplastics from laundry wastewater:

“In lab tests, the BAW setup was found to capture 95 percent of PET (polyethylene terephthalate) fibers, and 99 percent of Nylon 6 fibers. Before the system can enter production, though, the fiber-separation process needs to be speeded up, as it would currently take washing machines quite a long time to drain.”

*Interesting advancement.
