Discover the Valorterre Provence platform in Lançon-de-Provence
Located in the département of Bouches-du-Rhône (13), the Lançon-Provence biocenter is a biological treatment platform for polluted soil.
The center covers 20,000 m² and has a treatment capacity of 70,000 t/year.
The Lançon-Provence biocenter handles materials polluted with biodegradable organic compounds such as fuel oil, crude oil, diesel and kerosene. The recovered soil is reused, for example, as fill material or in landscaping projects.
expertises
With its expertise in the management of impacted materials, our team receives, controls, analyzes and sorts the excavated material. This characterization makes it possible to determine the path of the soil within the platform and to carry out the appropriate management according to the type of pollutant and the concentrations.
Biological degradation (with or without stimulation) is achieved by conditioning and placing the excavated soil in a biopile or biotank. The control of chemical, physical and biological parameters creates a favorable environment for the development of micro-organisms that will eliminate the organic pollutants.
Taking charge of the complete cycle of treatment of polluted materials until their final recovery, our teams ensure their traceability in the greatest respect of the regulatory and environmental requirements:
