A team of researchers at the Korea Institute of Science and Technology has developed a floating drone that captures microplastics from water using advanced tooth-like structures. The drone, which relies on surface tension to collect microplastics ranging from 1 micrometer to 4 millimeters, can achieve over 80% recovery efficiency for plastics like Styrofoam, takeout containers, and plastic grocery bags.
The technology works by creating a “water bridge” that traps microplastics in place. The drone moves autonomously across water surfaces, effectively acting as a robotic vacuum cleaner for oceans, lakes, and rivers. This system can also be applied to stationary systems like water treatment filters in aquaculture farms.
Eliminating microplastics from bodies of water can prevent marine organisms from ingesting harmful materials and protect food chains. By reducing waste, humans are less likely to eat seafood riddled with plastics, improving health and mitigating climate change.
The development of this technology highlights the potential for innovative solutions to combat plastic pollution. Other initiatives include non-profit The Ocean Cleanup’s plastic-removal system and everyday products like water bottles and grocery bags that come in plastic-free options.
