Great Bubble Barrier catches plastic before it reaches ocean

The Great Bubble barrier, preventing plastic waste from flowing into the oceans via the rivers, is catching enthusiasm globally. A recent pilot in the IJssel river in The Netherlands demonstrated the success of the method.
The elegant invention creates air bubbles which form a barrier that traps plastic in rivers. Carried by the current, the plastic collides with the wall of bubbles. The plastic waste is thus captured and directed to the waterfront to be cleaned up. Last November, the part of the IJssel near Kampen was the first location to test the bubble screen outside the laboratory. More than 80% of the test material was captured (News Item Plastic Soup Foundation, 21 February 2018).
