The Amsterdam-based start-up The Great Bubble Barrier is the winner of the Postcode Lottery Green Challenge 2018. During the final, 29-year-old Anne Marieke Eveleens convinced the international jury that her “Bubble Barrier”, a revolutionary air bubble curtain that combats the plastic soup in our oceans was the winner.

As the winner, she will receive a cheque of EUR 500,000 to further develop her green innovation. The second prize of EUR 200,000 goes to Reverse Resources from Estonia, a software platform for the clothing industry’s recycling process. The other three finalists will each take home EUR 100,000. This brings the total prize pool of one of the biggest sustainability competitions in the world to EUR 1 million. In addition to the prize money, all five finalists will receive six months of expert coaching to improve the likelihood of their businesses succeeding.


The Great Bubble Barrier
 has developed an air bubble screen for use on riverbeds that catches plastic before it arrives at sea. Approximately 80% of the plastic floating in the oceans enters the sea via rivers. In order to tackle plastic soup, The Great Bubble Barrier sends high-pressure air through a perforated tube on the riverbed. This creates an air bubble curtain that blocks both the stream of plastic waste on the surface and the floating microparticles underwater. The plastic then floats to the waterfront along the air bubble curtain, where it is collected for recycling.

Anne Marieke Eveleens: “We were tipped off about the competition really at the last minute. The fact that I am standing here now as a winner is beyond my wildest dreams! The prize money will help us to attract new talent, but also to develop our own plastic capture system. In addition, we can now put in a “Bubble Barrier” in the Netherlands. Fantastic!”
