Closure of the Metaleurop Nord plant in February 2003 created a serious economic and social crisis, leading to major environmental and health consequences.
Placed in receivership, the former foundry was unable to fulfill its legal obligation to clean up and restore the site.
In response to a request issued by public authorities and various regional actors, SITA Nord proposed an original project, labeled the "SITA AGORA eco-cluster", whose function was to associate site pollution cleanup with dismantling of the plant and a sustainable transformation in favor of green technologies and businesses.
The former foundry emitted every year 130,000 tons of lead, 100,000 tons of zinc and another 250,000 tons of sulfuric acid. SITA has made the commitment to rehabilitate this 50-hectare site, which for many years had been considered France's most heavily polluted.
