VW Bio-Bug Runs on Energy From Human Waste
The energy potential in methane gas continues to fascinate bio-energy scientists worldwide. The newest innovative approach to a seemingly inexhaustible supply of methane is a Volkswagen Beetle dubbed the Bio-Bug that runs on methane gas from human waste.
A local sewage treatment plant in Bristol, UK is sponsoring the Bio-Bug with surplus biogas originally produced to generate electricity for a local power station. The Bio-Bug can run for a year on the methane produced from the waste of 70 area homes.
The biogas that is the Bio-Bug fuel source relies on anaerobic bacteria digestion and carbon dioxide removal. The fairly simple process has potential for a number of electricity-generating applications that would not only help break reliance on fossil fuel energy, but also cut down on the use of landfills to handle excess waste.
Although lacking the cute Bio-Bug moniker, more than 11,500 vehicles in Sweden use biomethane derived from sewage. This obvious success as well as the apparent practicality of the VW Bio-Bug is encouraging the UK company, GENeco to consider converting a number of company fleet vehicles to run on human waste generated methane biogas.
