Every polluted site is unique and requires an ad hoc solution. Séché Eco Services, relying on its research office, accompanies companies or local administrations in order to find the most appropriate solution. The treatment of material can be done off site (elimination through the external chain), on-site (biological, physico-chemical treatments, …) , in situ (aquifer, soil treatments,…), or can be confined. Specific know-how has been developed by our team over many years, thanks to the expertise Séché has developed on its own sites on the rehabilitation of industrial sites or former waste recovery sites (both hazardous and non hazardous). Following the decontamination, rehabilitation or redevelopment actions can be determined, relying on Séché’s skills on the biodiversity management.
