UK's first 'poo bus' goes into service between Bristol and Bath

The UK's first bus powered entirely by human and food waste has gone into service between Bristol and Bath.

The 40-seat "Bio-Bus" runs on biomethane gas generated through the treatment of sewage and food waste.

The eco-friendly vehicle can travel up to 300km (186 miles) on one tank of gas, which takes the annual waste of about five people to produce.
