A “poo bus” enters regular service today in Bristol, UK. The commuter bus runs on biomethane gas produced by food waste and faecal matter. Fittingly, it will service Route Number Two and run four days a week.
Bristol Sewage Treatment Works produce 17 million cubic metres of biomethane a year, according to Gizmag.
The Bio-Bus is a 40-seater shuttle capable of travelling up to 300 kilometres on a tank of bio-methane gas with fewer emissions than diesel-powered buses, according to Geneco, the company that makes it.
“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,” Geneco general manager Mohammed Saddiq told Gizmag.
Supermarket chain Sainsbury powers one of its store using the same technology.
