A 40 seat ‘Bio-bus’ has been launched today (20th November 2014) running between Bristol and Bath. In a sustainable and innovative approach to reducing carbon emissions throughout the UK, the bus runs on gas which is generated through the treatment of sewage and food waste.
A full tank of gas will run for 300km. It has been estimated that the annual food and sewage waste from one person would allow the Bio-Bus to run 60km.
The biomethane gas is being produced at Bristol sewage treatment works run by GENeco, a subsidiary of Wessex Water.
GENeco general manager Mohammed Saddiq said: “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 fuelling the Bio-Bus.
“Gas powered vehicles have an important role to play in improving air quality in UK cities, but the Bio-Bus goes further than that and is actually powered by people living in the local area, including quite possibly those on the bus itself.” (Source: Edie.net)
Fear not, the bus produces odour free emissions. This could prove to be a viable sustainable alternative source of fuel emitting up to 30% less carbon dioxide than diesel vehicles.
It will be interesting to see what the future holds for the use of human and food waste in all of our vehicles and even our homes.
