Affectionately known as ‘Poo Bus’, the 40-seater shuttle is can travel up to 186 miles on one tank of gas. The annual food and sewage waste produced by one person would fuel the bus for up to 37 miles.
As impurities from the gas have been removed, its combustion produces virtually odour free emissions.
The environment-friendly bus emits 30 per cent less carbon dioxide than a diesel powered vehicle.
The bus is operated by the Bath Bus Company. It will transport people between Bristol airport and the centre of Bath.
The biomethane gas is generated via a process called anaerobic digestion at the Wessex Water sewerage plant that is run by the energy firm GENeco.
GENeco general manager Mohammed Saddiq said, “The Bio Bus is actually powered by people living in the local area. It will defeinately play prominent role in ensuring a pollution-free environment.”
