Britain's first "poo bus", which runs entirely on gas generated by human and food waste, is to go into service later this month. Powered by biomethane gas, the Bus will use waste from more than 32,000 houses along its 15-mile route.

Operated by bus company First West of England, the bus, which can seat up to 40 people, was unveiled in the Bristol area last autumn.

Transport company First is showing off the bus in Bristol on Tuesday and it will operate four days a week on Service 2, from 25 March. If the route proves a success, First will consider introducing more "poo buses".

James Freeman from First West of England said: "Since its first unveiling last year the Bus has attracted worldwide attention and so it's our great honor to bring it to the city. The Bus made an appearance running between Bath and Bristol Airport at the end of last year, but it's only actually been used once before in the center of Bristol itself."

He went on: "The very fact that it's running in the city should help to open up a serious debate about how buses are best fueled, and what is good for the environment."
