Simple filters could help remove microfiber pollution from your laundry. But experts say a broader portfolio of solutions is needed to address the problem.
revealed new methods in this vein. Under Armour is targeting 75 percent “low-shed” fabrics in its products by 2030.
These approaches would at best reduce microfiber emissions, not eliminate them. So another field of research is what Blackburn calls “biocompatibility”: making microfibers less harmful to nature. California-based companyIntrinsic Advanced Materials sells a pre-treatment, added to fabrics during manufacturing, that it claims helps polyester and nylon biodegrade in seawater within years rather than decades.
Lest anyone forget about washing machines, there’s R&D going after them, too. In January Patagonia and appliance giant Samsunga model that they claim cuts micro plastic emissions up to 54%. It’s already rolled out in Europe and Korea. At around the same time, University of Toronto researchers published research on a coating that, they claim, makes nylon fabric more slippery in the wash, reducing friction and thus microfiber emissions by 90 percent after nine washes.
the researchers tut-tutted governments for their focus on washing-machine filters, which they called a “Band-Aid” for the issue.One continuous thread through all these efforts, of course, is that everyone is working with imperfect information. The emerging science on microfibers – and microplastics in general – suggests they’re a gritty, but doesn’t yet show the magnitude of their harm to humans and other species.
