Last Thursday, Great-Britain’s first ‘poo bus’ made its maiden ride. Powered enirely by human feces and food waste, the Bio-bus can travel up to 186miles on one tank of the biomethane gas produced out of the waste by anaerobic bacteria. The bus will transport passengers between Bath city centre and Bristol airport, around 10 000 people a year. The engine is very similar to common Diesel engines, yet carbon dioxide emissions are at least 30% lower. Most important, the fuel is completely renewable and sustainable. It’s an example that with current technology it’s possible to create sustainable public transport which doesn’t compromise on comfort and yet increases the air quality.
