Bubble screen
Every minute, the equivalent of one full garbage truck of plastic trash is dumped in the sea. In total that is eight billion kilos per year. Eighty percent of those plastics come directly from use on land.
The Bubble Barrier creates a bubble screen by pumping air through a tube with holes located on the riverbed. Current solutions catch floating debris, but a huge proportion of debris travels underwater. Using the natural current, the bubble barrier creates an upward flow all the way from the riverbed to the surface. This guides the waste to the riverbank, making it accessible for removal.
This innovative concept is based on existing technology. It increases oxygen in the water and does not require changes in infrastructure or policies. It is easily scalable.
