Emergency intervention after industrial accidents and natural disasters

When an industrial accident, chemical accident or natural disaster occurs, a quick response by environmental experts experienced in dealing with chemical and environmental risks is vital to prevent the propagation or spread of pollution.
Our teams can intervene anywhere on the globe, for any type of pollution or risk.
Our chemical intervention unit boasts specially trained experts in the management of waste, whether it involves a single risk (chemical, biological, etc.) or combined risks (chemical and biological, etc.).

For all pollution risks

Our waste treatment and management experts can intervene as part of cleanup or destruction operations, regardless of the type of pollution involved.
We oversee the confinement and packaging of hazardous waste, along with the necessary administrative procedures to ensure traceability through to the treatment equipment used.
Our Trédi Salaise (Isère – France) facility operates a direct service with authorisation to treat waste involving chemical risk, biological risk, and waste that is highly odorous.

  • Organic pollution
  • Pollution involving biological risk
  • Pollution involving chemical risk
  • Radiological pollution
  • PCB or pesticide pollution
  • Asbestos
  • Accidental spillage of industrial sludge and effluent

From diagnosis to confinement and treatment

Our multi-disciplinary teams help with administration and the management of all types of emergency treatment operations.
We offer mobile equipment solutions to pre-treat waste before storage. By modifying the chemical nature of the waste, we make it inert before storage and thus can avoid the release of pollutants into the environment.

Our teams include experts in biodiversity-related matters.

We work alongside you throughout the cleanup process through to remediation of the impacted site:

  • analysis
  • identification of onsite or offsite treatment solutions
  • earthworks
  • waste packaging
  • confinement, stabilisation
  • site security
  • destruction, demolition
  • transport of waste to treatment units
  • administrative follow-up
  • remediation

Reference : Emergency intervention: Management of waste generated by the Probo Koala – Ivory Coast

19 August 2006: spillage of liquid waste with high hydrocarbon and soda content in the Ivory Coast – 17 sites impacted.
Significant release of H2S leading to 17 deaths.
Intervention by the UN and WHO to begin cleanup.
15 September 2006: Ivory Coast and Tredi signed a contract for the cleanup of the impacted sites and the treatment of waste.

Treatment solution

Excavation and pumping of waste, packaging and transfer for destruction to the Tredi Salaise facility.
Creation of two direct services (solid and liquid) at the Salaise facility to treat the waste without prior unpacking.

Services performed

  • Sampling and analysis
  • Security management: training of teams, implementation of procedures
  • Excavation and pumping
  • Packaging of effluent in iso-containers
  • Packaging of contaminated soil in big bags and 200 litre casks
  • Administration: submission of request to import waste (Basel Convention) – total authorised capacity: 10,500 tonnes of waste
  • Transport management: roll-out of a multi-mode solution (boat, transport to the port of the Salaise Industrial Zone)
  • Destruction of the waste: direct service

Key figures

Human resources: 40 people
Technical resources:

  • 1,000 tonnes of material transported at the impacted areas
  • 560 containers of polluted soil
  • 54 iso-containers of contaminated effluent

Duration of the intervention: 4 months
