Talk about a gas guzzler: a new bus in Britain runs on biomethane fuel produced by humans sewage and food waste.
The Bio-Bus—or as it’s more affectionately known, “the poo bus”—can travel up to 186 miles on one tank of gas, which takes the annual waste of about five people to produce, the BBC reports. A single passenger’s annual food and sewage waste can fuel the Bio-Bus for 37 miles.
The bus, which emits up to 30% less carbon dioxide than conventional diesel vehicles, will shuttle people between Bristol Airport and Bath.
GENeco general manager Mohammed Saddiq said, “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.”
