Despite the development of large scale and much advertised attempts to clear plastic from the ocean, a much more efficient method is to catch it before it even gets that far. The Dutch startup The Great Bubble Barrier is a simple, yet effective method to catch plastic pollution in rivers before it flows to the ocean. By pressing air through a perforated tube, it creates an underwater bubble curtain. Placed over the full width and depth of a river, the Bubble Barrier catches plastic pollution without interfering with regular river activities.
