London buses are set to be fuelled by a rather unusual item - waste coffee grounds.
Royal Dutch Shell and eco company Bio-bean announced the move today (November 20), according to Reuters.
Both also revealed that the biofuel being produced, which includes coffee oil, can be used in the buses without the need for modification.
Bio-bean claims coffee sales create more than 200,000 tonnes of waste each year in London, and the company is collecting as much waste as it can from both factories and coffee shops. This is then dried out in order to create the coffee oil.
The founder of the company said: “It’s a great example of what can be done when we start to reimagine waste as an untapped resource."
Bio-bean and its partner, Argent Energy, have also already claimed they have enough coffee oil in order to run one bus for an entire year.
Transport for London has recently been trying to use more biofuel in an attempt to reduce pollution in the city and it is also reportedly putting a fuel made from cooking oil on trial.
