Researchers may have found an effective, green way to remove microplastics from our water using readily available plant materials. Their device was found to capture up to 99.9% of a wide variety of microplastics known to pose a health risk to humans.

    “To create bioCap, the researchers used sawdust as a substrate through which to filter water, given its superior chemical and physical stability and the fact that it contains cellulose, hemicelluloses, and lignin, which facilitate efficient water transport. They modified the sawdust by adding tannic acid, a naturally occurring plant polyphenol found in almost all plants without underground root systems.”

      Also, the article doesn’t mention anything about nanoplastics, which are far more dangerous. Nanoplastics have a larger surface area, which makes them more reactive - they can also penetrate cells, and cause damage to DNA, proteins, etc.
