Coffee Waste Powering London Buses

Biofuel created from waste coffee grounds is helping to power some of London's buses.

The technology firm Bio-bean has been producing biofuels from coffee waste. Oil extracted from the collected used coffee grounds in Bio-bean's factory is being processed and is blended into a B20 biofuel. The firm believes it would take just over 2.55 million cups of coffee to create enough biofuel to run a London bus for a year, once the oil has been blended with diesel.

Transport for London, the local government body responsible for the transport system in the British capital, has turned to biofuels to reduce the city's transport emissions. Biofuels made from waste products such as cooking oil and tallow from meat processing are already being used in many of the capital's buses.
