Arthur Kay was studying architecture at The Bartlett, UCL where he was set the challenge of designing a coffee shop and coffee roaster. During the process he, “quickly realized that coffee was being wasted everywhere. It was pouring out of coffee shops, office blocks, transport hubs and factories.”
Instead of seeing this waste as a challenge, Kay looked at it as an opportunity and discovered a way to refine the phenomenally high oil content in waste coffee grounds into biodiesel. He calls this remarkable discovery a ‘happy surprise’, but what happened next was considered, determined and very coincidental.
