The former waste treatment platform
The former storage site of 1.2 ha was acquired in November 2014. The site is in a mix peri-urban area of Annecy (Haute-Savoie, France) which sheltered single-family homes, craft and industrial activities.
Hydrocarbons represented the most significant contamination. The remediation strategy for the site consisted in the excavation, disposal and offsite treatment of the contaminated soil. The hydrocarbon and PCB hot spots were valorised, respectively in a bio-treatment centre and by thermal desorption, representing 15,000 and 1,400 tonnes of polluted soil.
The obtained permit authorises the development of a 9,800 sqm surface area, which is divided into 6,800 sqm of open market housing and 3,000 sqm of social housing. A partnership with developer Neosens Immobilier has been signed as part of this development.
