The Norwegian city of Oslo is converting its buses to run on human waste in an attempt to be carbon-neutral by 2050.Starting later this year up to 80 buses will be adapted use biomethane which will be captured by sewage plants.
At the plants microbes will be used to break down the raw human sewage releasing the gas which can be contained and used to run modified engines.
City bosses claim the move will cut fuel costs as the same time as being good for the environment.
