The British company has developed Geneco anaerobic digestion system that allows the gas produced by sewage treatment and biofuel.
At first Avonmouth facility (located in the county of Bristol-UK) electricity generated from biogas plant only, but over the years, continuous technological improvements allowed the purification of gas increase production, thus able to become an alternative to usury in the national grid.
The manager of the company, Mohammed Saddiq said that because a significant amount of surplus gas Geneco had the need to find a viable alternative to the use of biogas, so after a few tests are able to develop a process that allows the use of methane as a biofuel.
It indicates that biogas can be used without affecting the car's performance or cause doubts about its safety after a treatment called "update". During this process the CO2 is separated from other components.
The first draft of four-wheeled eco Geneco Bio Bug is called, it is mentioned that the little goat can travel 160 000 km a year just with biogas generated by 70 houses.
Unfortunately not mentioned details about the mechanics of the car, however it is likely that its structure does not differ much from existing LPG fueled cars.
