Tiny fibers create unseen plastic pollution

18/02/2019

While the polyester leisure suit was a 1970s mistake, polyester and other synthetic fibers like nylon are still around and are a major contributor to the microplastics load in the environment, according to a Penn State materials scientist, who suggests switching to biosynthetic fibers to solve this problem.
