Washing clothes, I would assume.

• hinkley 5y ago
  Washing clothes sends microplastics to the water treatment plant. Notwithstanding leaky sewer systems (and especially combined stormwater systems), that's a centralized problem that can be solved in one spot. Drying your clothes is a point source problem. Every dryer vent is spewing microplastics into every yard and street. The lint trap only catches the largest fibers.
