London’s coffee industry creates over 200,000 tonnes of waste every year, so what do we do with it? Entrepreneur Arthur Kay’s big idea is to use his company, bio-bean, to turn 85 per cent of coffee waste into biofuels for heating buildings and powering transport.
Bio-bean is founded on the premise that there is no such thing as waste, just resources in the wrong place. Spent coffee grounds are highly calorific and contain valuable compounds, making them an ideal feedstock from which to produce clean fuels.
Bio-bean works within the existing energy and waste infrastructure to collect spent coffee grounds from coffee shops, offices, transport hubs and coffee factories, recycling them into sustainable and high-performance products and displacing conventional fuels and chemicals.
