This is the GENeco Bio-Bug, a methane-fueled VW Beetle cabriolet converted by The Greenfuel Company to showcase yet another alternative fuel possibility. Using "specialist equipment", GENeco processes waste using anaerobic digestion. Basically, anything biodegradable is eaten by bugs that, in an oxygen-free environment, release methane.
In order to make that methane usable as biogas (i.e. work without noticeable side effects), the CO2 has to be filtered out.
The firm claims that the Bio-Bug can run for up to 10,000 miles annually using gas collected from just 70 homes. Also, if it were possible to convert all the gas collected from the Avonmouth location, GENeco says it could potentially use this process to reduce CO2 emissions by approximately 19,000 tons.
