What has been happening this week in Amsterdam? The finalists Pierre-Yves Cousteau, Diego Acevedo, Arthur Kay, Devin Malone and Trang Tran arrived last Monday, and have had a busy schedule since...Pitch training, presentation skills were addresses, tips & tricks of the trades and more. Have a look!

Once upon a time, two years ago…
September 2012, four nervous nicely dressed Dutchies are waiting for the subway in New York. The subway will bring them to the Rockefeller Center where the finale of the 2012 Postcode Lottery Green Challenge will take place. When the second prize is announced, the four start to celebrate. Their start-up won the $125,000 prize to further develop their sharing platform Peerby; a website and app that allows people to borrow the things they need from people nearby.

It is hard to believe that one year ago, we were writing our pitches, scheduling film shoots for our video and eagerly awaiting a response from the Postcode Lottery Green Challenge. Since winning the Postcode Lottery Green Challenge, every week for us is a new challenge and new growth for bioMASON. One key word that has come up every day this past year would have to be: momentum.

Diego Acevedo of Bluerise and Devin Malone of One Nights Tent in The Netherlands, Pierre-Yves Cousteau of Turbosail from France, Trang Tran and her company Fargreen from Vietnam and Arthur Kay of Bio-bean from the UK!

Congratulations, you made it to the Postcode Lottery Green Challenge 2014 finale! We are looking forward to meet you in person and to see your business pitches during the Deciding Round on September 11th.


Planet earth has roughly 6 billion “usable” hectares to offer, soil where plants and trees can grow in order to provide food and shelter for our ecosystem. Two billion of those hectares have been seriously degraded to accommodate our less than desirable lifestyle (think: deforestation, urbanization and the effects of climate change). Wetlands account for half of those degraded hectares; the remaining one billion hectares are the playground for Jurriaan Ruys’s Land Life Company.


Coffee starts the day for billions of people over the world, but very few consider what happens to the waste from each cup. As it happens, coffee grounds are an excellent base material for clean biofuels, and a good alternative for fossil fuels. Arthur Kay, the founder and CEO of bio-bean, recognised that this waste could easily become a sustainable resource for biofuels.

Every day, the world consumes nearly 1.5 billion cups of coffee. Those billions of cups of coffee create 25 million metric tons of coffee-ground waste every year, leading to 90 million metric tons of CO2 emissions. While studying at the Bartlett School of Architecture, UCL, London, Kay was working on a project on closed-loop systems. He was designing a coffee shop and found himself becoming interested in waste management, after realising that coffee was being wasted everywhere. That’s how, in 2013, he founded bio-bean, which takes coffee-ground waste and recycles it into advanced biofuels.


Power cuts are common in national parks throughout the UK, creating a welcome environment for alternative energy sources. Due to the visual impact of large wind turbines, however, they are prohibited in the protected scenery. And, as you might imagine, solar power can’t quite reach its full potential in the UK’s rainy climate.

This was reason for Win Keech, a former Rolls Royce turbine engineer and Co- Founder of The Power Collective (TPC) with Dean Gregory, to develop the RidgeBlade. The Ridgeblade is a wind turbine, yet instead of being located in an open field or the ocean, it is mounted to the roof of a building and is much smaller and less obtrusive than the wind turbines we’re used to. The roof of a building offers a perfect place for a wind turbine seeing as air travels much faster when pushed over the peak of a roof, just as over the airfoil on an airplane wing.


We asked some of our previous winners Eben Bayer, Molly Morse, Scot Frank, Ginger Dosier and Nick Christy if they have any useful tips for turning a plan into reality. Here is what they said:
