The competition has expanded to become one of the largest annual sustainability competitions in the world. There is a total of €1 million in combined prize money for the five best start-ups, of which €500,000 is for the winner. In addition to the prize money, all finalists will receive over six months of expert coaching to optimise their business opportunities. With this international competition, the Postcode Lotteries are helping start-ups from around the world to bring their innovations to market. Business plans can be submitted via www.greenchallenge.info until 1 May 2019.

As part of its mission to contribute to a greener world, the Postcode Lotteries are organising this international competition for the 13th time this year.

Margriet Schreuders, head of charities at the Dutch Postcode Lottery said, “We hope this year’s entries reflect the challenges the world is facing, such as plastic pollution, energy demand, food wastage and urbanisation. For me it is really inspiring to see how the entrepreneurs think in terms of solutions rather than problems. They’re working on solutions for today’s reality.”

Air bubble curtain to combat plastic soup

Last year, the winner was The Great Bubble Barrier. 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.
