14.The British have long been known for their love of tea,but people in London also drink a lot of coffee.In fact,the average Londoner reportedly drinks 2.3 cups of coffee every day.
And now,waste coffee grounds(咖啡渣)will be used to help fuel part of the city's transportation system.
A technology company announced on Monday that some buses will be using a biofuel (生物燃料) that contains coffee oil.
The company,bio-bean,and its partner,Argent Energy,say they have made enough coffee oil to power one of London's famous double-decker buses for a year.
The announcement made bio-bean a trending story on social media.
The government agency Transport for London has been turning to biofuels to cut production of carbon emissions.Carbon emissions are the gas produced by the burning of carbon,and the gas is released into the atmosphere.
London's mayor,Sadiq Khan,said last month that his city has a "health crisis...caused directly by poor-quality air".The government has taken steps to discourage people from driving cars that do not meet European Union emissions requirements.
Bio-bean said Londoners produce over 200,000 tons of waste coffee grounds a year.The company said it collects waste grounds from chain coffee shops and factories.The grounds are dried and processed to remove coffee oil.
"It's a great example of what can be done when we start to reimagine waste as an
untapped resource," said one of bio-bean founders Arthur Kay.The coffee fuel technology has been receiving support from the oil company Royal Dutch Shell.
