Check out this new form of poo-blic transport - Britain's first bus powered entirely by poo and food waste hits the road on Thursday.
The Bio-Bus is a shuttle service between Bath and Bristol Airport.
It runs on a gas called biomethane, which is generated through the treatment of sewage and food waste.
The bus has 40 seats, and can travel up to 186 miles on one tank of gas, which needs the annual waste of around five people to produce.
Engineers think the Bio-Bus could be a greener way of running public transport.
