The Great Bubble Barrier uses bubbles to push plastic and other debris in rivers to the surface and collect it before it can reach the sea. Air is pumped from a tube at the bottom, stopping waste to cross the wall of bubbles at the surface while also using the flow of the water to guide it into a collector where it can be disposed properly.
The system is developed by Scientists in the Netherlands and is already successfully used in Amsterdam. Hopefully this smart & relatively simple method can be used to clean and keep other waterways around the world free from plastic pollution.
