Plans for more poo-powered buses to hit Bristol and Bath

Wessex Bus, First West of England and GENeco have submitted bids to low-emission vehicle grants scheme for more bio-buses

Dozens of "number two" buses - powered entirely by gas generated from sewage - could be picking up passengers in Bristol next year.

Wessex Bus is hoping to run a 20-strong fleet in Bristol, while a rival operator, First West of England, is looking to bring 110 poo-powered doubledeckers to the city.
