Yahoo News London buses now run on coffee just as much as you
London buses now run on as much coffee as you do, thanks to a new biofuel scheme.
As of yesterday (November 20), waste coffee grounds are being used to help power some of London's buses, aimed at reducing transport emissions (via BBC News).
The biofuel is created by blending oil extracted from coffee waste with diesel, and technology firm bio-bean says it has produced enough coffee oil to power one bus for a whole year.
Transport for London has already been using biofuel from waste products such as cooking oil in London's 9,500 buses, but this is thought to be the first time a coffee-based biofuel has been added to London's transport system.
And it's not like there isn't enough coffee waste to go around as the British Coffee Association says a whopping 55 million cups of coffee are drunk every day in the UK.
Londoners alone create 200,000 tonnes of coffee waste every year, according to bio-bean who take the used coffee grounds from cafes and instant coffee factories and extract oil from it.
Buses can be powered by the fuel without the need for modification and bio-bean believes it'll take around 2.55m cups of coffee to create enough biofuel for one London bus to run for a year.
"It's a great example of what can be done when we start to reimagine waste as an untapped resource," the company's founder Arthur Kay explained.
