GENeco Bio-Bug protoype that runs on human excrement unveiled
9 August 2010

A VW Beetle, dubbed the “Bio-Bug”, has been converted to run on methane gas produced by human excrement.

The prototype was created by GENeco, a Bristol firm specialising in sustainability and organic waste.

See pictures of the GENeco Bio-Bug and how the process works

The car can travel for 10,000 miles – one average motoring year – using an amount of excrement equivalent to that produced by 70 homes over a one year period. Its economy is 5.3 miles per cubic metre of biogas and it can reach a top speed of 114 mph.

The car is started with regular petrol, then automatically switches to methane once the engine has warmed up. Mohammed Sadiq of GENeco said: "If you were to drive the car you wouldn’t know it was powered by biogas as it performs just like any conventional car."

The gas used for the Bio-Bug came from the Wessex Water plant in Avonmouth and is generated through anaerobic digestion, which uses bacteria to process organic matter.

Before the gas can be used to power the car, the CO2 is removed to improve performance.

Our Verdict

Volkswagen Beetle

The Volkswagen Beetle is only the third all-new model since the original launched in 1938. It is based on the Mk6 Golf, but the base car is far better

Possibly the ideal solution to Ministerial cars for all the elected officials and MPs etc?? Surely their verbal output would be adequate to run a fleet of these without any running cost to the tax payer?

surely dubbed the "Dung-Beetle"? must have been said by everyone.

isnt gas measured with a pressure figure also? as people might think the car might realistically have a range of about 2 miles for an average sized fuel tank.

if methane isnt going to just be a smell on the wind and engines can readily run on the stuff, russia could make good use from its Siberian bogs/ice fields containing vast tracts of methane.

The dung beetle joke is the only point for this article. Methane is widely used in Otto engines for passenger cars in many places, dubbed "compressed natural gas", requiring little engine modification except for an additional set of injectors. The innovation is in the way the CNG is obtained, not the car that uses it.

Is that engine naturally aspirated or turdocharged?

I'll get me coat.....
