London buses are now powered by coffee

The B20 biofuel is partly made from waste coffee grounds and has been added to the London bus fuel supply chain without any great need to vehicle modification. "We've started in the UK, but imagine the potential of a country like The United States that drinks more than 164 billion cups of coffee a year", he added.

Some of London's buses will run on waste coffee grounds from today.

Oil giant, Shell has announced that it is working in collaboration with bio-bean and the coffee drinkers of London to power some of the city's buses.

In order to produce B20, Bio-bean collected some of these waste coffee grounds from high street chains and factories, which were dried and processed before coffee oil was extracted.

So far, 6,000 litres of coffee oil has been produced, which, if used as a pure-blend for the bio component and mixed with mineral diesel to form a B20, could help power the equivalent of one London bus for one year.

Transport for London has recently been trying to use more biofuel in an attempt to reduce pollution in the city and it is also reportedly putting a fuel made from cooking oil on trial.

Bio-bean has been using coffee to deliver energy for a short while now, giving households the ability to burn coffee instead of wood for their fires. A good idea can come from anywhere, but with the scale and commitment of Shell, we can help enable true progress.

Up to 50,000 tonnes of waste coffee grounds can be recycled in Bio-Bean's factory annually, with the coffee sourced through partnerships with coffee shops and factories across the UK. Bio-Bean is also targeting the United States for its coffee-fused fuel source.

Currently, Bio-Bean has enough on hand (six thousand litres) to power one bus for a year, but access to raw material shouldn't be an issue once things get up and running.
