Dismantling and recovery
Industrial sites, buildings, vehicles and equipments are all subject to recycling goals set by European regulations. SITA develops specialised streams for their dismantling and deconstruction and to optimise the recuperation and recovery ratio.
Dismantling the sites
In order to dismantle and decontaminate a site, SITA uses a strict approach with several key steps:
- upstream audit of the risks, the project scope and the human and material means to factor in so as to agree to a prevention plan
- hazardous waste destocking: the technicians identify, sort and prepare the waste for transportation
- dispatching to appropriate treatment and recovery streams
- site shutdown management: dismantling buildings and equipment
Recycling complex products
According to strict regulations, 50% to 80% of the WEEE and 95% of the VHUs have to be recycled. Several materials and even dangerous products (gases, glues, solvents and paints) are used in manufacturing these products. SITA came up with various dismantling processes to get the materials of a good enough quality to be used again in industrial manufacturing processes.
Encouraging industrial partnerships
SITA cultivates industrial partnerships to optimise recycling and recovery. In 2005, SITA started working with Airbus to create a deconstruction and recovery unit for aircrafts at the end of their life. On the same basis, SITA started working with Renault to develop an efficient VHU dismantling process.
10 million inhabitants used over 900 distributors and collection points
90 % de valorisation des avions en fin de vie
25 vehicles are dismantled per day / per unit on average
- Industrial partnership with Renault to encourage eco-design
In 2008, SITA developed an industrial joint venture with Renault to develop a recycling activity.
On the Re-Source Industries (Loir-et-Cher) construction site, INDRA recovers an average of 25 vehicles a day: fluids and gases are decontaminated, pollutants extracted (batteries, etc.), internal equipment and spare parts recovered and the metal carcass is crushed, etc.
85% of the elements of a vehicle are recovered.
- Industrial reconversion of Metaleurop Nord (Noyelles-Godault)
SITA started a worksite by associating the dismantling of the factory (lead, zinc and sulphuric acid production), decontamination of the 50 hectares (Seveso II) and its reconversion into an eco-pole. After evaluating the risks in details, SITA took charge of the dismantling, decontamination and rehabilitation into an industrial eco-pole for the environment trade: SITA Agora.
> 83 buildings asbestos-free and demolished, 9,000m2 rehabilitated offices and workshops
> 190,000 tonnes of waste extracted
- Waste destocking in the dismantling of the Lambiotte factory in Prémery (Nièvre)
Following a call for tender, the ADEME (French Environment and Energy Management Agency) charged SITA Rekem with the chemical decontamination of the abandoned factory.
According to this contract, LaboServices is responsible for a smooth operation and the coordination of the worksite where SRA SAVAC, specialised in sanitation, and industrial maintenance and local providers will work (electricians, trimmers, metal dealers).
They must handle the following operations:
- evacuating and disposal of 3,900 tonnes of hazardous waste, of which 1,500 tonnes are tainted charcoal powder stored on site;
- building security as well as hazardous waste identification, sorting, recuperation and reconditioning;
- draining, cleaning-up and removal of tanks and ponds;
- transportation and disposal of hazardous waste and charcoal.
These operations are expected to take 14 months.
