Now, we're all for upcycling and recycling, but when we heard about the bus which was recycling human waste, we weren't too sure what we thought of it.
However, reading a little deeper and it's not quite as stinky as it seems, the bus is actually powered from biomethane gas, which is generated from the treatment of sewage and food waste at a processing plant. One waste plant alone can produce 17 million tonnes of the gas a year, and a single tank of the gas is enough to power the vehicle for 190 miles, and is produced from the typical annual waste of just five people.
This bus clearly shows the value of waste, and looking at alternative fuel sources, it seems this really could be onto something. Using a gas which is produced anyway through the treatment of sewage and food waste, it seems to be a bit of a no-brainer.
The first bus of its kind has made its first journey today, so we will have to wait and see what the response is and whether they decide to produce more of these vehicles on a larger scale.
What do you think, is it a good idea?
