Site deconstruction and soil decontamination

SUEZ deconstructs industrial sites in the end-of-life phase and decontaminates soil and water tables. The aim is to achieve optimum levels of recovery and reuse. From treating contaminated soil through to managing UXO clearance, SUEZ provides its expertise to industry to ensure regulatory compliance, re-use of assets and site safety.

Optimising deconstruction and recovery

The decontamination process is prepared following a rigorous procedure in several key stages.

A strict approach

To dismantle and decontaminate a site, we use a strict approach with several key steps.

  • Diagnostic: prior audit of the risks, the project scope and the human and technical resources to mobilise, through to defining a prevention plan
  • Hazardous waste removal: identification, sorting and preparation of waste for transportation
  • Dispatch to appropriate recovery and treatment streams
  • Site shutdown management: equipment and building disassembly

Fully control site deconstruction and transformation

We enable you to optimise management of the deconstruction and decontamination work:

  • Base the deconstruction project in a global strategy
  • Ensure the total safety of the work site and its legal compliance
  • Prepare work sites with a thorough understanding of the challenges posed by the site: definition of a strategy, site preparation, technical diagnostics
  • Lead and optimise activities: site organisation, legal and administrative management, project management
  • Analyse and manage the impact of the work on the site’s environment

Ensure safety and traceability

We guarantee extremely strict monitoring of health and safety conditions on our remediation sites.

  • One-time or continuous testing of the working atmosphere
  • Supply of protective equipment
  • Individual monitoring of each member of staff working on-site
  • Analysis, sorting and the possibility to choose channels
  • Complete traceability of all the waste produced on the site

Combining deconstruction and waste recovery

Site deconstruction and decontamination includes the real-time monitoring of waste, management of hazardous waste, and recycling of waste that can be recovered as new resources.

Real-time waste monitoring

We implement digital waste tracking systems to:

  • Monitor the waste streams in real time (collection, treatment, recovery)
  • View your data and analyses, manage invoicing and regulatory and administrative monitoring from our digital platforms

Industrial cleaning for safe decontamination

Our sophisticated non-intrusive cleaning methods limit risks to health, safety and the environment.

Recycling complex products

Our procedures make it possible to recover materials of sufficient quality to be reused in industrial manufacturing processes:
  • Compliance with the recycling requirements set by the regulations: 50 to 80 % for WEEE and 95 % for end-of-life vehicles
  • Management of complex waste: waste composed of several materials and containing hazardous products (gas, adhesives, solvents and paint)

Managing hazardous waste

We provide the logistics for treating hazardous waste as part of deconstruction and decontamination operations, enabling you to:

  • Safeguard operations via our logistics system
  • Guarantee human safety and risk prevention
  • Reduce the environmental impact by optimising sorting, storage and transportation of hazardous waste
  • Benefit from waste traceability at the best price
  • Select the solution adapted to each type of waste

Recycling metal and glass

We offer glass and metal recycling solutions to transform waste into resources:
  • Optimise and safeguard resources
  • Produce replacement raw materials
  • Provide a secure supply of materials and cut costs
  • Save energy and contribute to the circular economy

Producing secondary raw materials

We manage trade in secondary raw materials in European networks:
  • Standardised quality adapted to the customer’s process
  • Continuous production and constant supply
  • Expertise in collection, sorting, packaging and production

Optimise logistics by combining delivery and collection

We optimise your logistics by grouping delivery of materials and waste collection:
  • Minimised environmental impact
  • Reduced distances, costs, time and risks linked to transport
  • Optimised lorry loads
  • Use of adapted, easy-to-handle containers

Using cleaner multi-modal means of transport

We promote the use of alternatives to road transportation, particularly for waste collection, such as river transport, railways or electric vehicles:

  • Optimised logistics efficiency (1 vessel = 16 lorries)
  • Reduced CO2 emissions
  • Monitoring system throughout the logistics chain
  • Reduced risk of accidents

Creating the conditions for a second life

The decontamination processes can be carried out at the place where the soils are located, or outside the site. Whether treating contaminated soils or managing pyrotechnical pollution, our experts operate to rehabilitate polluted sites and soils, thus creating the conditions for a second life.

UXO clearance

Our expertise also applies to the defence sector, with our specialised teams of explosives experts or E.O.D.(Explosive Ordnance Disposal) specialists:

  • Site audit
  • Destruction of objects
  • Raising and identification of targets detected
  • Breakdown of ammunition
  • Deconstruction of buildings

Adopting a suitable decontamination technique

We offer different decontamination processes according to the types of contamination and the configuration of the site:
  • Decontamination in situ
  • Off-site decontamination for excavated soil: treatment platforms to treat and recover polluted soil which is then reused (Neoter®)
  • Soil without excavating (standard procedures: venting, bioventing, sparging)
  • Excavated soil: biological treatment (biopile), waste volatilisation (Volatilis®), or on-site pre-treatment (screening, crushing, Rotalis®, Mecalis®, washing, etc.)
  • Simultaneous treatment of soil, water tables and floating matter (E.T.P.® specific patented procedure)
  • Treatment of chlorinated pollution (innovative in-situ oxidation techniques, Oxidis® or for anaerobic biodegradation, Bionappe®)

Recovering polluted soil

To best address our customers’ needs, we designed the Neoter® platform enabling polluted soil to be reused:
  • Optimise transportation, treatment and costs
  • Maximise soil recovery
  • Pretreatments (screening, crushing, phase separation)
  • Biocentre® (a process using the natural action of micro-organisms to break down pollutants naturally)
  • Recover polluted soil in the form of alternative products for construction work (road beds, fill material, etc.) covering material for waste storage sites or material for precast concrete

Decontaminating water tables

We treat contaminated water tables to achieve complete decontamination of the site:

  • Wide range of treatment solutions for polluted water tables
  • Environmental recovery and ecological restoration
  • Use of the decontaminated water table to restore the water supply to the natural environment or for industrial use
  • Improvement of well performance for water table decontamination
  • Constant and ecologically sustainable water quality

PCB decontamination

We enable you to comply with the Stockholm Convention adopted by EU legislation concerning the elimination of PCB by 2025:

  • Ensure the safe recycling and disposal of transformers containing PCB
  • Eliminate potential environmental pollution with a secure recovery process for equipment contaminated with PCB
  • Controlled disposal of end-of-life transformers in strict compliance with the legislation
  • Comprehensive service from collection to recovery of the equipment

Recovering hazardous waste

We offer hazardous waste a second life by recovering the secondary raw materials and the energy produced by treating this waste:

  • Reduce your ecological footprint
  • Preserve and optimise resources
  • Enhance the value of your brand by your commitment to the circular economy
  • Guaranteed safety and legal compliance
  • Recovery of chemical and mineral products, solvents, salt, metals, glass, etc.

Transforming waste into alternative fuels

Our solutions enable us to optimise waste co-processing and recycling by transforming waste into alternative fuels:
  • Fuel production by co-incineration of liquid and solid oily waste to replace fossil fuels
  • Cost optimisation by reducing energy costs
  • Reduction of your environmental impact and your CO2 footprint
  • Enhanced resource efficiency by joining the circular economy
