THIS BUS RUNS ON POO

UK First it was pee-powered electricity, now there are poo-powered buses. And it’s all made in Bristol. News from Vattenfall recently reported on the Bristol researchers behind pee power. Now, a company in the same city has started to run a bus fuelled entirely by human waste.

It might seem like a smelly business, but the aim is actually to improve air quality. By using waste from a sewage plant, methane gas is created to power the bus. It can travel 300 kilometres on one tank of refined poo - the equivalent of five people’s waste for a year. 
“Gas-powered vehicles have an important role to play in improving air quality in UK cities, but the Bio-Bus goes further than that and is actually powered by people living in the local area, including quite possibly those on the bus itself”, says Mohammed Saddiq, general manager of the local waste treatment plant GENeco, in an interview in The Guardian.

Poo fuels the commuter bus
Britain’s first poo-powered bus, nicknamed “the number two”, was introduced at the end of last year and transports people between Bath and Bristol Airport. Since then, it has generated worldwide attention and will now start operating four days a week in the city. 

Future sustainable fuels
Bristol has had a special relationship with excrement throughout history. Back in 1997, two researchers at Bristol University established the Bristol Stool Chart that classifies the shape and consistency of human poo. Maybe it can be revived as a stinky guide to future sustainable fuels.
