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.

Founders wisdom “Businesses don’t succeed due to sustainability alone. The best new companies in the world are both financially and environmentally sustainable. Always consider the commercial angle and, above all else, be rigorous. Many good ideas fail due to poor execution.”
