Bio-Bus Using Fuel from Wessex Water-Geneco Sewage Plant
Gets Wide Attention as the ‘Poo’ Bus, aka a Scania Enviro 300

The UK’s Bath Bus Company, a subsidiary of France’s RATP, is operating a 41-passenger biomethane-fueled Scania Enviro 300 bus for service to the Bristol Airport. The fuel is derived from sewage via anaerobic digestion at a Wessex Water-Geneco wastewater treatment plant. The vehicle has garnered wide attention as the “poo bus.”

Nottingham-based Roadgas supplied this portable CNG fueling equipment for the Wessex Water-Geneco Bio-Bus project.

“Running on waste products that are both renewable and sustainable, the bus can travel up to 300 kilometers [186 miles] on a full tank of gas generated at Bristol sewage treatment works,” states a Geneco release.

“Through treating sewage and food that’s unfit for human consumption we’re able to produce enough biomethane to provide a significant supply of gas to the national gas network that’s capable of powering almost 8,500 homes as well as fueling the Bio-Bus, Geneco GM Mohammed Saddiq says in the announcement.

Project partners are making no secret of the source of the CNG fuel for the Scania Enviro 300 operated by Bath Bus for service to the nearby Bristol Airport.

Roadgas for the CNG Fueling

The 300 kilometers, says the company, “takes the annual waste of around five people to produce.”

“The driving force behind this project is to demonstrate that large vehicles powered by gas engines such as those produced for many years by Scania can operate on a product that is 100% renewable, sustainable, produces lower emissions and of course it is carbon neutral,” says Bath Bus engineering director Collin Field.

“It is totally sustainable,” Field told F&F. Nottingham-based Roadgas furnished a portable, fast-fill CNG fueling unit for the project, he notes. It’s located at the Geneco facility outside Bristol.

A CNG Double-Decker in Development

The 40-foot (12.2-meter) Scania bus has a 9-liter, 270-horsepower Scania OG9 G04 natural gas engine with eight roof-mounted Type IV fuel cylinders from France’s Ullit. Approximately 80 CNG-fueled Scania buses are operating in the UK, primarily with Stagecoach and Reading Buses, says Scania UK special projects manager Alan Martin.

Martin told F&F that Scania is developing the first double-deck CNG bus, expected to be available late next year or in early 2016.

Birmingham-based CNG Services Ltd provided specialized engineering support for the pipeline-injection side of the Geneco Bio-Bus project.
