Bio-bean, the clean-tech company, announced that it will use recycled coffee beans to fuel some of London's buses. Bio-bean has partnered with Shell and Argent Energy to develop a new type of biofuel for the London bus fueling chain, where Contains some coffee oil.HK Royal Dutch Shell and bio-bean said that this fuel can be used directly without any adjustment.
Arthur Kay, bio-bean founder, said: 'This is a great example of how we can think of garbage as an untapped resource.'
The team has now produced enough coffee for a year on a bus.
The London Department of Transportation said they have been using biofuels to reduce their carbon emissions and have also tried cooking fuels from the restaurant industry.
The company said Londoners consume an average of 2.3 cups of coffee a day and 200,000 tons of used coffee beans a year.
They collect discarded coffee beans from coffee shops, offices and factories, and every tonne of coffee beans they collect can emit as little as 6.8 tons of carbon dioxide per year.
The coffee beans are then dried and extracted, then mixed with other fats and oils to make up 20% of the base, which is then blended with mineral diesel to form B20 biofuels.
This biofuel can be used directly on buses in London without any adjustment.
