Description of the Project

The new environmental complex of Landes Franches located in the city of Saint Christophe du Ligneron integrates two separate systems to treat household waste of 2 of the 7 collection areas in the department of Vendée.

VINCI Environnement has fully designed and constructed the Mechanical and Biological waste sorting unit of this facility, so that the organic portion of the waste is extracted and converted into compost.

The residue is landfilled at the non-hazardous waste storage area built on the same site. It is compacted into high density bales via a baler to reduce their storage volume and optimise the site’s long-term operation.

The facility will produce about 13,800 tons of compost per annum.

Are of the site : 5.5 hectares
Annual treatment capacity : 55,000 tpa of Residual Solid Waste
