The UK's first ever bus powered on human and food waste has taken to the road today which engineers believe could provide a sustainable way of fuelling public transport - cutting emissions in polluted towns and cities. The 40-seater Bio-Bus, which runs on gas generated through the treatment of sewage and food waste that's unfit for human consumption, helps to improve urban air quality as it produces fewer emissions than traditional diesel engines. Running on waste products that are both renewable and sustainable, the bus can travel up to 300km on a full tank of gas.
The UK's first ever bus powered on human and food waste has taken to the road today which engineers believe could provide a sustainable way of fuelling public transport - cutting emissions in polluted towns and cities.
The 40-seater Bio-Bus, which runs on gas generated through the treatment of sewage and food waste that's unfit for human consumption, helps to improve urban air quality as it produces fewer emissions than traditional diesel engines.
Running on waste products that are both renewable and sustainable, the bus can travel up to 300km on a full tank of gas generated at Bristol sewage treatment works – a plant run by GENeco, a subsidiary of Wessex Water.
This week GENeco became the first company in the UK to start injecting gas generated from food waste and sewage into the national gas grid network and at the same time installed a gas refuelling plant for the bus.
GENeco general manager Mohammed Saddiq said: “Through treating sewage and food thats 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.
“Using biomethane in this way not only provides a sustainable fuel, but also reduces our reliance on traditional fossil fuels.”
The Bio-Bus can travel up to 300km on a full tank of gas, which takes the annual waste of around five people to produce.
Using the annual waste generated from one bus load of passengers, would provide enough power for it to travel a return journey from Lands End to John O’Groats.
The first passengers to get on board the Bio-Bus today were visitors to the UK who were commuting from Bristol Airport to the historic city of Bath.
Bath Bus Company, which is operating the service, said the bus was greener for the environment and added that it was extremely pleased to be using the Bio-Bus for its rapidly growing A4 service from Bath to Bristol Airport via South Bristol.
