The technology, developed by a team at the University of California, uses specially designed filtration membranes combined with biodegradable chemical attractants that cause microplastics to aggregate for easier collection. During a three-month trial in coastal waters, the system removed approximately 92% of microplastics from processed water without harming marine life. “This is the first demonstration that large-scale microplastic removal from oceans is feasible,” explains marine biologist Dr. Elena Santos. The team plans to deploy the system in several pollution hotspots next year.
