Nano- and microplastics are seemingly everywhere -- water, soil and the air.


While many creative strategies have been attempted to get rid of these plastic bits, one unexpectedly effective solution for cleaning up drinking water, specifically, might be as simple as brewing a cup of tea or coffee.

Boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present.

Boiling hard water, which is rich in minerals, will naturally form a chalky substance known as limescale, or calcium carbonate (CaCO3). Results from these experiments indicated that as the water temperature increased, CaCO3 formed incrustants, or crystalline structures, which encapsulated the plastic particles.
