YEREVAN, 20 NOVEMBER, ARMENPRESS: Britain's first bus powered by human waste is taking to the streets. The 40-seater "Bio-Bus" is fuelled by biomethane gas generated by the treatment of sewage and food waste at a processing plant.

Armenpressreports that a single tank of the gas, which is produced using the typical annual waste of five people, is enough to power the vehicle for 190 miles. The maiden voyage will see the first passengers travel on the route from Bristol Airport to the historical city of Bath, Somerset.

The gas is being produced at a Wessex Water sewerage plant run by energy firm GENeco.

The annual waste of a bus-load of people would provide enough power for a return journey from Land's End to John O'Groats while producing less emissions than a diesel engine.

GENeco this week also became the first company to start delivering gas generated from human waste directly to 8,300 homes by the national grid.
