UBC researchers discover way to filter microplastics out of water using plants

Researchers at the University of B.C. have discovered a way to filter microplastics out of water using biodegradable forest byproducts such as bark and wood dust. Scientists at UBC’s BioProducts Institute found that if they added tannins—natural plant compounds found in unripe fruit and a popular additive in wine—to a layer of wood dust, they could filter out nearly all microplastic particles from water.
