Britain's Bio-Bus is the first of its kind to be powered by poop
A Bio-Bus which runs entirely on human waste is now open to passengers in Britain, heralding a new and exciting time for environmentally-friendly transportation.
Seven million tonnes of food waste is thrown away each year in Britain. These scraps, along with plenty of human sewage, can provide enough fuel to power 8300 homes. How? In a similar way to our digestive system, bio-organisms break down the waste and produce bio-gas. This gas is then collected, purified, and turned into bio-methane, which can be used for heating and transport. The 40-seater Bio-Bus bus can travel almost 200 miles (300km) on a full tank of waste. The annual waste generated from one bus load of passengers would provide enough power for a return journey from Land’s End (Southernmost tip of England) to John O’Groats (Northern Scotland).
Engineers from company GENeco believe the Bio-Bus could provide a sustainable way of fueling public transport while improving urban air quality. The gas, bio-methane, produces fewer emissions than traditional diesel engines and is both renewable and sustainable. The bus is refueled at GENeco’s gas to grid plant at Bristol sewage treatment works, and currently runs between the city of Bath and Bristol airport.
