I’ll power buses with coffee grounds says winner of £400,000 eco prize

London buses could one day be fuelled by coffee leftovers after a project to turn grounds into biofuel won a European environmental prize.

Eco-entrepreneur Arthur Kay today said the £400,000 prize money would enable his start-up company bio-bean to revolutionise transport.

Bio-bean, based in Tower Bridge, has already signed up some of the nation’s biggest coffee chains to collect waste from their shops and factories.
