BBC News - 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.

Bristol sewage treatment works processes around 75 million cubic metres of sewage waste and 35,000 tonnes of food waste each year.
A total of 17 million cubic metres of biomethane, enough to power 8,300 homes, is generated annually at the plant through a process known as anaerobic digestion.
