The UK currently has a bus running between Bristol Airport and Bath city center that’s powered by food waste and human feces (or poop).
The poop bus is powered by biomethane gas, which is generated through the treatment of human and food waste, reports Mashable.
Since we all eat a fair share of food, and then we excrete that food, why not make the most of that excrement we’re producing. Right?
But don’t worry, you won’t come off the bus smelling like poo. The bus’ fuel has had its impurities stripped leaving behind a “virtually odorless” emission. Foodbeast reports, “With the gas tanks on the roof of the bus, it’s pretty much as stinky as any other regular form of public transportation.”
According to Clean Energy Fuels, biomethane gas, when used to power vehicles, can reduce greenhouse emissions by 88% compared to gasoline.
Yes, poo can save the planet.
