Soil remediation for a unique industrial rehabilitation project in the French town of Neuville-sur-Saône
Giving a historic industrial site a second life
These activities include the Neuville-sur-Saône site, which has undergone a real transformation in just a few years: having used chemical processes to produce medicines for 150 years, the site became a biotechnology centre for vaccine production at the end of 2013.
To achieve this, the teams reinvented the site, beginning in 2012 with the dismantling and demolition of the previous industrial buildings and the remediation of soil and groundwater. SUEZ contributed its expertise to the conversion by rehabilitating a 3.5-hectare urban plot.
SUEZ deployed a team of 20 people for this 30-month project.
Site remediation involves a rigorous process consisting of several key stages, including an assessment and analysis phase to define appropriate solutions for processing the pollutants (solvents, acetone, alcohol etc.) and design a specific plan for the work.
Recovery and redevelopment

Depending on the pollutants identified, soils were sorted, treated and sent for recovery or disposal. Over 80,000 tonnes were treated during the project and sent to our NEOTER® platforms for reuse as alternative materials for cement-making or for disposal via the thermal desorption process.
Finally, in preparation for Sanofi’s project, nearly 70,000 tonnes of backfill and about 15,000 tonnes of topsoil were used to redevelop the site following the excavation work.
