A vehicle running on human waste offers a sustainable alternative to conventional fuel-powered vehicles.

Bio-Bug is a modified Volkswagen Beetle that runs on human waste and is the UK's first car to be powered by sewage byproducts. The car was made by Wessex Water, a sewage utility company based in Bristol, that used excess methane gas produced in one of its treatment plants as fuel for the car. The company claims that the Bio-Bug is extremely efficient and needs waste from just 70 local homes to keep it running for a year.
