>> It's the fuel many of us drink to power our day, and now some of London's buses will be driven by your caffeine addiction. Clean technology company bio-bean is using waste coffee grounds in a new biofuel.>> So bio-bean's a green energy company and we collect waste coffee grounds from all across the UK, from thousands of different outlets.
And then turn those waste coffee grounds, at our factory in Cambridge here, into advanced biofuels.>> The biofuel blends coffee oil with diesel and is being added to the London bus fuel supply chain without any need for modification. It will be the first ever bus network powered by waste coffee grounds.
Bio-bean and its partner Argent Energy claim to have produced enough coffee oil to power one bus for a year. It collects waste grounds from High Street chains and factories, which are then dried and processed to extract the oil. It says Londoners create 200,000 tons of coffee waste a year, which would be enough to fuel roughly one-third of the capital's bus network.
Globally, millions of tons of waste coffee grounds are sent to landfill where they emit methane, a potent greenhouse gas. And bio-bean thinks its technology could be used worldwide.>> And so we want to work with companies, save them money, and, importantly, save CO2 emissions.>> Transport for London has already been turning to biofuels to curb carbon emissions.
And the coffee fuel technology has been supported by Royal Dutch Shell, who acknowledge the future of energy is going to be a mix.
