By the end of 2015, all British Airways flights out of London City Airport will be fuelled by rubbish - the paper, food scraps, garden clippings and other organic detritus discarded by the citys residents. But before it goes into planes, the rubbish will be processed at GreenSky London: a biofuels plant under construction on the eastern side of the city. Each year, the facility will take in some 500,000 tonnes of the citys waste and will transform the organic component into 60,000 tonnes of jet fuel, a similar quantity of diesel fuel combined with petrol-like naphtha, and 40 megawatts of power.
