London buses to be perked up by coffee to reduce emissions

LONDON - A coffee-based biofuel will be used to help power London's public buses from Monday in a bid to reduce transport emission, local media reported.

Bio-bean, a green-energy startup, said it has produced enough coffee-derived biofuel to power one bus for a whole year, the BBC reported.

The company collects waste coffee grounds, mostly from London's coffee shops, for processing and tops the resulting mixture with a range of animal and vegetable oil.
