Royal Dutch Shell (Shell) announced a collaboration with bio-bean, a clean technology company, that will power London’s buses using a biofuel made partly from waste coffee grounds.  Bio-bean collects waste coffee grounds from high street chains and factories, dries and processes the grounds, and then extracts the coffee oil, which Argent Energy, bio-bean’s fuel partner, processes into a blended B20 biofuel.  The biofuel contains a 20 percent bio-component that contains part coffee oil and is being added to the London bus fuel supply chain without the need for modification.  To date, 6,000 liters of coffee oil have been produced, which is capable of powering one London bus for a year.  The collaboration represents the most recent part of Shell's #makethefuture energy relay, which supports entrepreneurs turning bright energy innovations into a positive impact for communities around the world.
