Catching plastic over the fu­ll width and depth of rivers and preventing plastic from ending up in the ocean.

Although at first it was thought that plastic pollution was a faraway problem floating out in the middle of the ocean, it is now clear that plastic is everywhere, including in the water we drink and the air we breathe. Plastic carried by water flows towards the sea and causes plastic pollution to reach the oceans. Rivers, or canals for example, transport a lot of plastic to the sea. To stop waste from floating from the canals to the rivers and seas, The Great Bubble Barrier came up with an idea. They created a bubble curtain by pumping air through a perforated tube on the bottom of the waterway. The bubble curtain creates an upward current which directs the plastics to the surface. By placing the Bubble Barrier diagonally in the river, the natural flow will push the plastic waste to the side and into the catchment system. From here it will be removed from the water for processing.
