  Based in Princeton since it launched in 2022, PolyGone Systems developed “a floating filter” that can capture most of the invisible tons of microplastics that stream into the world’s waterways every year. […] Liu outlines how PolyGone’s filter works: Made of thousands of silicone fibers, it traps small particles due to their hydrophobic properties, meaning the microplastics stick to the bristly brush-like filter. […] Banks goes on to say that the filter allows wastewater systems to recover the collected plastics, separating them from the bristles. Since most plastic is either buoyant or lighter than water, they are usually found on the surface or in the first 30 centimeters of the water column, where PolyGone’s filter operates. So a brush-like filter floating on the water it seems
