Bio Fuel Daily writes that the work belongs to farmers at the Guerin family farm in the southern Dordogne region, which was founded in 1926. The barn which hosts the cows, mostly automated, has two tanks that are partly buried beneath the ground and they are used to capture the methane that comes from manure.

Special processes are being used to turn the organic matter into a diesel alternative, called renewable natural gas for vehicles, or bioNGV, which is claimed to be cleaner and cheaper than the fossil fuel itself.

Farmers use this new alternative to power the cars and the one New Holland tractor that can run on bioNGV.

Bertrand Guerin, the owner of the farm, hopes that soon, his truck that he uses to collect milk will be using the same innovative fuel alternative.

He also believes that it can also be used to attract visitors from countries like the Netherlands and the UK, where cars running on natural gas are more common.

To further promote this product, Bertrand and other farmers founded a new chain of gas stations, called Biogaz de France, where the owner of the near century-old farmhouse is vice president.

However, he is concerned that big energy companies, such as Engie, might transition to the same power source, as they are interested in moving away from fossil fuels themselves.

He asks big companies to let farmers handle this sector, as farming accounts for around 23% of the global greenhouse gas emissions, so the methane can be put to better use by those who generate the most of it.

Bertrand claims that every day, the machines are processing 40 tons of waste, partly manure, partly food waste, which are converted into fuels for vehicles.

"We mix it, ferment it. Bacteria break stuff down and CO2 and methane are released", Guerin explained.

What's interesting is that most of the generated gas is actually used to create electricity that is fed into the grid, enough to power around 1.000 households, while only a small part of it is being purified and compressed to be used in vehicles.

"This is just the beginning of the story," Guerin concluded.
