The Great Bubble Barrier is a Dutch startup that stops plastic from entering the ocean. They achieve this by pumping air through a tube with holes, which is strategically placed diagonally on the bottom of a river.

The rising bubbles result in an upwards current which brings the waste to the surface and is directed to the banks or a catchment system, where it’s collected for recycling. Fish, other wildlife and ships can easily pass through the bubbles.
The first project has been installed in an Amsterdam canal to prevent plastic from flowing into the North Sea. The team has also showcased a small size river with flowing water at an expo as an example of what could be applied in a waterway.
Ninety percent of the plastic found in the ocean comes from the 10 most polluted rivers in the world. This smart solution aims to reduce the 8 million tons of plastic that enter the ocean every day and to give us waste-free rivers.
