SUEZ remediates polluted soil and water tables. From the treatment of polluted soil, to pyrotechnical remediation, we offer customers our expertise to guarantee regulatory compliance, the recovery of assets and the safety of the work site.
Preparations

Control the pollution and reduce environmental impacts

Rigorous processes

SUEZ follows a thorough process to remediate a site, consisting of several key steps that are codified and defined in the standard LNE NF X 31-620-1-2-3-4:

  • Diagnostic: Definition of needs, preliminary audit of risks, the scope of the project and the required human and technical resources, up to the definition of an accident prevention plan.
  • Rehabilitation engineering: Assistance for the contracting authority, analysis of the design, the technical and financial feasibility, laboratory tests and field tests to guarantee the most suitable treatment solution and confirm our commitment to achieve a result.
  • Rehabilitation works: Execution of the remediation works with the solution best suited to meeting the needs of our customers.

 

 

Focus on the works design plan

Laboratory and field tests: helping to design and size the operations

Methodological developments and increasingly complex problems (remediation targets, geology of the environments, complex pollutants, etc.) mean that laboratory and/or field tests have now become an essential phase in certain remediation operations.

The experts in SUEZ’s internal laboratory have developed numerous tests to verify the effectiveness of remediation solutions in advance.

We are capable of testing most remediation techniques and have all the equipment required to perform chemical or geotechnical analyses in the laboratory. We also use numerous field tests to try out the most appropriate techniques directly on site and to assess their performance.

Laboratory and field tests provide valuable decision support for the choices of the technical and economical optimisation of a treatment solution.

Fully control site deconstruction and transformation 

Our teams perform a variety of general operations to prepare the site to be treated in order to guarantee the success of our remediation missions:

  • Dismantling of industrial buildings: we can organise the complete dismantling of your buildings as part of our remediation operations.
  • Dismantling of overhead and underground infrastructures: we can remove your facilities from the site to prepare to remediate the land and dismantle different types of infrastructures, from overhead and underground tanks, to canopies and ductwork, while taking all the necessary precautionary measures:
    • Cleaning and degassing of tanks and piping by hydrojet
    • Extraction (mechanical excavators or lifting equipment)
    • Loading and transportation of tanks on flat-bed trucks
    • Monitoring of disposal (recovery in metal recycling centres)

Remediation of industrial wasteland

Our expertise also covers the remediation of urban industrial wasteland for property development projects. We can manage complete projects to redevelop abandoned industrial sites or industrial sites to be re-qualified, from the risk audit and assessment, to the remediation of the sites and their redevelopment.
Remediation

Create the conditions for a second life

Our remediation solutions can be used on the site where the soil is located, or off-site. From the treatment of soil polluted by hydrocarbons, chlorinated solvents, metals, etc., to the control of pyrotechnical pollution, our experts can remediate polluted sites and land to offer them a second lease of life.

Made-to-measure remediation

We offer various treatment solutions for pollution that depend on the deadlines or the configuration of the site:

  • In situ remediation, without excavating the soil
    • Conventional treatments, such as venting, bioventing, sparging, etc.
    • Simultaneous treatment of the soil, groundwater and floating materials (specific patented E.T.P.® process)
    • Treatment of chlorinated pollution (Oxidis® in situ oxidation or Bionappe® anaerobic biodegradation)
  • Off-site remediation (soil excavation):

    • The polluted soil is sent to certified centres (biocentres, sites that treat inert, non-hazardous and hazardous waste)
    • Total traceability of the soil sent off site using waste tracking documents
    • Optimisation and recovery of tonnages on the Neoter® platform (learn more)
  • On-site remediation (on-site excavation):
    • Biological treatment in biopiles and by controlled volatilisation (Volatilis®)
    • On-site pretreatment (screening, crushing, Rotalis®, Mecalis®, etc.)
  • Design office support
  • Pyrotechnical diagnostic
  • Safety of drilling operations and earthworks
  • Destruction or dismantling of ammunition
    • Inerting of firing waste
    • Pyrotechnical remediation
    • Explosive ordnance disposal (EOD)


We intervene in different situations: infrastructure projects, civil works, rehabilitation of industrial sites, treatment of pyrotechnical waste.

Recovery

Recovery of polluted soil

Site remediation involves tracking the waste in real time, managing hazardous waste and recycling waste that can be recovered as new resources.

After reception and inspection of the polluted soil, it is trated, sorted and sent for either recovery or disposal. The NEOTER® platform can be used for different types of treatments and pretreatments, including screening, crushing, washing, biotreatment or dewatering.

These platforms comply with the current regulations (sites classified for environmental protection, authorisations, development applications, etc.).

Reducing CO2 emissions: developing cleaner means of transport

Depending on the situation, we encourage the use of alternative means of transport to roads, such as waterways, especially for the transportation of polluted earth to the treatment centres to reduce CO2 emissions and optimise your logistics. The advantages of the alternative means of transport are :

  • Optimisation of your logistics (one 4,400 t barge convoy replaces 220 20 t trucks on the roads).
  • Reduced CO2 emissions: Transport on waterways is one of the solutions that produces the least atmospheric emissions. Most of our NEOTER® platforms can be accessed by waterway.
  • A monitoring system covering the entire logistics chain
  • Reduction of the risks of an accident

We guarantee that the transportation of the soil is tracked from end to end, using waste tracking documents.

Ensuring the safety of people

We strictly control the health and safety conditions on our rehabilitation sites. Our field staff is trained in the rules of conduct to be obeyed. Moreover, our QHSE organisation:

  • Oversees the safety of our personnel
  • Implements a continual accident prevention policy for the entire staff:
  • Guarantee the regulatory compliance of our activities
  • Analyse and manage the work’s impact on the site’s environment
  • Prepare the work sites with in-depth analyses of the specifics of every project
  • Make the health and safety of the personnel a top priority
  • Produce the activity reports required to draw up a QHSE review for every customer.
