From the toilet to the tank of the car: they create an ecological fuel based on … human excrement!

The struggle to obtain new ecological fuels reducing environmental pollution has reached unexpected limits: in Andalusia, Spain, eleven cars are already tested powered by a biogas obtained from human excreta.

The conversion process is divided into five phases. First the waste is separated into solids (remnants of toilet paper, wipes, etc.) and liquids in the wastewater treatment plant. Second, in two huge pools, microalgae and bacteria mix with liquid waste to obtain purified water and biombad.

In the third step, the digester goes into action, a very large reservoir that ferment the mixture at 35 degreesit goes into a gaseous state and converts it into biogas (it is stored at room temperature in the gas meter). The fourth phase consists of pbad the fuel through the purification plant comply with the European standard and the fifth, move it to the pump.

Behind this project called All-Gas is the signature FCC Aqualia (the third largest private water company in Europe), which He has worked with scientists from the University of Cadiz, Almería, the Netherlands and the United Kingdom.. The Spanish car manufacturer Seat has also joined the group.

The base of operations is in Chiclana, where currently 80,000 people live. Whenever one of them looses the chain, he collaborates with the process. At the moment, the city has only one loading point in the El Torno treatment plant.

The specialists badure that, powered by this fuel, cars emit up to 80% less nitrogen oxide and 20% less carbon dioxide this diesel supplied. In addition, biogas is three times cheaper than diesel.
