From the ‘Eeewww’ files – Britain’s first ever ‘Bio-Bus’ goes into service March 2015. And we do mean goes. Running on biomethane from human and household waste, the affectionately-named ‘poo bus’ can travel up to 300km on one tank of gas, which takes the annual waste of about five people to produce. Congrats to the bus line for putting the crap back into scrap.
