Arthur Kay and his company Bio-Bean took first prize in the 2014 Postcode Lottery Green Challenge, winning €500,000 to develop their business. The London-based company collects spent coffee grounds from local businesses and uses them to manufacture biodiesel and biomass pellets.
Since the competition finale, a display on Bio-bean can be seen at the London Science Museum, clearly explaining the process of extracting bio-fuels from waste coffee grounds.
Looking back on the competition, the winner of the 2013 Green Challenge Ginger Dosier points out that it is not competitive at all. "On the contrary: the feeling of belonging to this wonderful family was and is the most fun thing about it!"
“The whole experience was surreal and everything went seamless. I went home a different person than I came, in a good way. More shaped. And everything was so well organised, there were no problems, everything was thoughtful.”
