London’s love for caffeine might soon present an environment-friendly vitality kick to its public buses, including its notable red double-decker bus.
About 6,000 liters of waste coffee grounds will be used as biofuel to power some of the city’s buses on Monday, which is enough to fuel a bus for a year.
Tech company Bio-bean is the brain-box behind this mind-blowing idea, and it has been producing fuel from coffee grounds since 2013, with financial and technical sponsorships from Shell.
Londoners are coffee lovers, and an average citizen consumes an average of 2.3 cups of espresso daily, adding to 2,00,000 tons of coffee grounds through the span of one year, according to data collected by Bio-bean.
Rather than transferring a ton of coffee grounds to dumping sites where it decays and discharges carbon dioxide and methane, we gather it, recycle it and transform it into biofuel, which can be used to supplant conventional energies,” said Arthur Kay, founder of Bio-bean.
Bio-bean gathers waste coffee grounds from different cafés in London and then process it in its recycling plant in Cambridgeshire.
Biofuel will reduce carbon emissions
It then sends the processed coffee oil to the Uk’s biggest biofuel manufacturer, Argent, which finishes it up with vegetable or animal fuels. The final product is comprised of 80 percent conventional diesel and 20 percent biofuel.
“Replacing conventional fuel with this new product will help reduce emissions from commuting vehicles by 10 to 15 percent, without increasing cost or modifying engines,” said Bio-bean.
The UK has a 9300-powerful fleet of transport buses which travel over 2 billion trips each year, but just 2,000 of the buses will use renewable energy as diesel-electric.
The biofuel meanwhile, can also be utilized by cars, taxis, and trucks.
Also, Bio-bean is aiming at Europe, specifically France, where they consume about 38 billion espressos every year.
