Plastic soup and batteries
One of the finalists is the start-up The Great Bubble Barrier that addresses the issue of the plastic soup in oceans. The company developed an air bubble screen for riverbeds that catches plastic before it arrives at sea.
Co-founder and female sea sailor Anne Marieke Eveleens (29) will pitch this entry during the finals.

TU Delft spin-off AquaBattery has developed an energy storage system that works on the basis of water and table salt instead of rare, and therefore expensive, raw materials. Because no chemical reaction is required to store and release energy, this innovation offers a sustainable solution for storing energy that has been generated from renewable resources, such as wind and solar energy. Emil Goosen (29), co-founder of AquaBattery, will represent the start-up.

Other finalists
The other finalists who will pitch their entry are from the UK, Estonia and USA, respectively:
● LettUs Grow with a method to grow crops with their roots hanging in a dense, nutritious mist
● Reverse Resources with a software tool that allows textile recyclers to gain better insight into the quality of the waste flow
● AlgiKnit with a textile fibre produced from seaweed

The finals will be held at the Gashouder venue in Amsterdam on 13 September 2018 and can be watched via livestream at www.greenchallenge.info.

Last year, the Rwandese start-up EarthEnable won the first prize with their sustainable alternative to cement.
