Construction of a mixed-type Bio GNV refuelling station, with a fast-loaded part accessible to the public (local authorities or companies, road hauliers, private individuals) and a slow-loaded part for the needs of the Régie Régionales de Transport des Landes and Trans-Landes. The objectives are to make it possible to stop the operation of dozens of diesel vehicles in favour of vehicles in the GNV which make it very possible to reduce emissions of gases harmful to the environment such as health, but also to allow the development of the local methanisation sector by natural waste.
