Coffee may be your own personal fuel, but Arthur Kay is working on making coffee a viable biofuel.
Kay was in the process of designing a coffee shop and roaster when he noticed that “coffee was being wasted everywhere. It was pouring out of coffee shops, office blocks, transport hubs and factories.” He knew there had to be a use for this discarded coffee, especially when he considered the high oil content in used coffee grounds.
And now Kay has created bio-bean, a company that has partnered with several coffee chain companies to collect London’s 200,000 tons of wasted coffee grounds. He then converts the grounds into biomass pellets that can be used for heating buildings. He’s in the process of helping coffee oil become a viable biodiesel, which could then power our modes of transport.
