Coffee to Help Power London's Buses
This is What's Trending Today...
Britain has long been known for its 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 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 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. A carbon emission is a gas produced by the burning of carbon. 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 coffee ground waste a year. The company said it collects waste grounds from chain coffee shops and factories. The grounds are dried and processed to remove the coffee oil.
"It's a great example of what can be done when we start to reimagine waste as an untapped resource," said Bio-bean founder's Arthur Kay.
The coffee fuel technology has been received support from the oil company Royal Dutch Shell.

长期以来，英国人以爱喝茶而闻名，不过伦敦人也喜欢饮用咖啡 。事实上，有报道称，伦敦人平均每天喝2.3杯咖啡 。
这家名为Bio-bean的企业及其合作伙伴Argent Energy表示，他们已经生产了足够多的咖啡油，能为伦敦一辆著名的双层巴士提供一年的燃料 。
为了减少碳排放量，英国政府机构“伦敦交通局”正在向生物燃料过渡 。碳排放是指碳燃烧后产生的气体 。这种气体会释放到大气中 。
上个月伦敦市长萨迪克·汗（Sadiq Khan）表示，该市出现了由劣质空气直接导致的“健康危机” 。政府已经采取措施，限制市民驾驶不符合欧盟排放要求的车辆 。
Bio-bean公司表示，伦敦市民每年会产生20万吨废弃咖啡渣 。该公司称，他们从连锁咖啡厅和工厂收集废弃咖啡渣 。将这些咖啡渣进行干燥和加工，提炼出咖啡油 。
Bio-bean公司创始人亚瑟·凯（Arthur Kay）说：“这是个绝佳的例子，让我们重新思考将垃圾变成未经开发的资源 。”
