"There is huge potential for this project to expand in the US, which drinks the most coffee on the planet, 400 million cups of per day", the company said in a written statement.
In an attempt to explore fossil fuel alternatives, a partnership between Shell, Argent Energy, biofuel company Bio-Bean, and Transport for London, the city's iconic double-decker buses will soon run on "B20 Biofuel", a proprietary combination of oil from coffee ground extracts and diesel.
Meanwhile, the companies said in a press release, "Shell and bio-bean announce that together they are helping to power some of London's buses using a biofuel made partly from waste coffee grounds".
To put recycled coffee grounds will firm bio-bean, reports the BBC. This is then mixed with other fats and oils to create a 20 percent biocomponent of B20 fuel.
Londoners consume an estimated 20 million cups of coffee each day, which adds up to roughly 200,000 tons of coffee waste over the course of a 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.
Shell's involvement in the venture forms part of the oil company's #makethefuture energy relay, which supports entrepreneurs in the energy sector. Founder Arthur Kay said it was a "great example of what can be done when we start to reimagine waste as an untapped resource".
Shell UK country chair Sinead Lynch explains the inspiration for the company's campaign. Bio-Bean also offers bio-mass pellets and Coffee Logs, which can be used on stoves and open fires. It should be noted that the sediment remaining after 2 550 000 cups of coffee, allows you to create biofuel, which is enough to refuel one bus during the year.
