The UK’s first bio-fuelled bus is now running between Bristol airport and Bath.
The 40 seat bus is operated by ‘Bath Bus Company’ and runs on Biomethane which is generated in a nearby plant by from food and sewage waste.
The route carries 10,000 people per month and the weekly food and sewage waste of one person can power the bus for 1 km.
The bus’ engine works on the same principle and a similar design to traditional diesel engines. The technology is widely used throughout the world and in fact bi-fuels account for 2.7% of the world’s transport fuels.
The gas is generated through anaerobic digestion – bacteria breaks down the food and sewage waste which produces the biomethane.
