It goes without saying that public transport systems around the world are moving to greener forms of power.
Buses in South Korea and the UK, for example, are being powered from electricity from underneath the road surface. Not only is the fuel for the Bio-Bus said to produce fewer emissions than traditional diesel engines, but it is also locally sourced.
“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,” says Geneco general manager Mohammed Saddiq.
“Using biomethane in this way not only provides a sustainable fuel, but also reduces our reliance on traditional fossil fuels.”
The new bus runs on biomethane fuel produced by humans sewage and food waste.
The Bio-Bus—or as it’s more affectionately known, “the poo bus”—can travel up to 186 miles on one tank of gas, which takes the annual waste of about five people to produce.
A single passenger’s annual food and sewage waste can fuel the Bio-Bus for 37 miles.
“The bus also clearly shows that human poo and our waste food are valuable resources.” Charlotte Morton, chief executive of the Anaerobic Digestion and Bioresources Association said.
“Food which is unsuitable for human consumption should be separately collected and recycled through anaerobic digestion into green gas and biofertilisers, not wasted in landfill sites or incinerators.”
Bristol sewage treatment works processes around 75m cubic metres of sewage waste and 35,000 tonnes of food waste collected from households, supermarkets and food manufacturers each year.
