The site of the former Frontignan la Peyrade refinery, located close to the town center and the coast, is undergoing a major environmental rehabilitation operation. For more than 3 years, teams from Antea Group and Séché Eco Services will be working to clean up the soil, while taking into account the severe constraints imposed by the proximity of local residents. This 11-hectare site presents a number of technical challenges and requires innovative solutions. It will enable the town of Frontignan la Peyrade to reclaim land for the development of a new district, thus meeting its objective of zero net artificial development.

After 14 months of an extraordinary decontamination project, the Saulnier ZAC in Saint-Denis (93) is ready to welcome the future Olympic Aquatic Centre. At the request of the Metropole du Grand Paris, the Séché Group and its partners, Antea and Charier, have joined forces to successfully complete this rehabilitation project, which is located a stone's throw from the Stade de France. A real collective success.

At the rehabilitation site for the Parc des Aiguilles in Ensuès-La-Redonne near Marseille, the Séché Éco-Services teams are putting the best of their decontamination expertise on display. To direct each type of waste to the appropriate treatment facility and to allow the contaminated soil to be reused, a full-fledged sorting centre must be set up on site.

Located on the Loire in the heart of the city of Tours, the Île aux vaches is home to all the drinking water wells that supply the city. Contaminated with asbestos following renovation work carried out in 2008, the island, which is classified as a Natura 2000 site and a natural area of ecological, faunistic and floristic interest, had to undergo a particularly complex decontamination operation. Armand Debar and his teams from Séché éco-services did everything possible to filter and evacuate the asbestos cement debris while preserving the silt and sand, preserving the ecosystem and taking all the necessary safety measures for asbestos waste.

Armand Debar, deputy operations manager, takes us on a tour of the demolition and asbestos removal worksite at a historic industrial site, the Lucien Coupet plant in Issoudun in the Indre department (36). Taken over in 2018 by Safran, its dilapidated facilities, formerly dedicated to the production of seats for the aeronautical industry, were to be razed. This was a complex project requiring increased vigilance in terms of the safety of employees and local residents.

It's a dark and snowy night, but isopropanol is threatening to spill into the ditch along the Mayenne highway. Séché Urgences Interventions teams are on the scene to pump out the hazardous product and get the waste under control so it can be eliminated. Busy night… and a cold one!

On April 9, 2020, firefighters in Rhone were faced with a tank containing 1,300 liters of an accidental mixture of nitric and sulfuric acids. The situation called for chemical risk experts with specific know-how and equipment. The site had to be secured quickly, and this unstable product had to be taken to a hazardous waste treatment center. A new mission for Séché Urgences Interventions.

On July 9 in the French town of Salaise-sur-Sanne, just south of Lyon, Séché Environnement’s Trédi plant and the OSIRIS economic interest grouping of the Roussillon chemical platform inaugurated their new heating network, commissioned this year. Financially supported by ADEME, the French agency for ecological transition, this new facility is expected to supply a total of 600,000 tons of steam to manufacturers within the Roussillon chemical platform, representing half of their energy needs. This energy will limit fossil fuel use and greenhouse gas emissions: Each year, 180,000 tons of CO2 will be avoided, the equivalent of the emissions of a city of 23,000 inhabitants.

In the middle of summer 2019, Séché Urgence Intervention decontaminated the Saint Benoît nursery school in Paris's 6th arrondissement, which had been polluted by lead from the roof of the nearby cathedral. A delicate job on a narrow street in the historic heart of the capital.

In late 2020, France's agency for ecological transition, ADEME, tasked the teams at Séché Urgences Interventions (SUI) with securing a former bleach production site in the French department of Somme (80). Contaminated with not only mercury but also asbestos and PCBs, the dilapidated buildings, production facilities, soil, and water will require all the expertise of our chemical hazard specialists.<br />
