A SCOTS transport operator is to introduce a bus which runs on human and household waste, goes into regular service later this month.

Powered by biomethane gas, the Bio-Bus, which has been dubbed the ‘poo bus’ will use waste from more than 32,000 households along its 15-mile route.

Operated by First West of England, an offshoot of Aberdeen-based FirstGroup, the vehicle will fill up at a site in Bristol, where sewage and inedible food waste is turned into biomethane gas.

Transport company First is showing off the bus which can carry up to 40 people in the city tomorrow and it will operate four days from March 25.

If the route proves a success, First will consider introducing more “poo buses”.

First West of England managing director James Freeman said: “Since its original unveiling last year the Bio-Bus has generated worldwide attention and so it’s our great privilege to bring it to the city, to operate – quite rightly – on Service 2.

“The Bio-Bus previously 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 centre of Bristol itself.”
