Destruction of hazardous waste, our speciality

Certain wastes that carry high chemical, environmental or biological risks need to be treated at highly specialised waste treatment plants.
Our Trédi Salaise (Isère – France) and Trédi St Vulbas (Ain – France) facilities have developed know-how that is recognised worldwide in the treatment of very specific hazardous waste.
We offer unique solutions for the treatment of industrial gases (UTM facility).
The Trédi Salaise (Isère – France) facility has developed a direct service allowing it to manage high-risk or highly odorous waste, without unpacking, thus preventing environmental and health risks.
The Trédi facilities are ISO 14001, ISO 9001 and OHSAS 18001 certified.


For all types of waste, even the most specific and hazardous

Our Trédi facilities are authorised to remove and destroy all hazardous waste, even the most specific types.

  • Waste containing PCB
  • POPs, phytosanitary products
  • Industrial gases
  • Highly toxic waste
  • Waste generating biological and/or environmental risks
  • Waste generating healthcare risks
  • E-waste
  • Weapons
  • Mercury waste
  • Multiple risks waste

From diagnosis to hazardous waste destruction

Our multi-disciplinary teams assist you in all stages of waste management, from identification to packaging through to administrative follow-up:

  • Administrative follow-up (Basel Convention)
  • Packaging
  • Transport
  • Analysis
  • Secure storage
  • Destruction

Reference : Destruction of obsolete pesticides (POPs) – Morocco

Implementation of the FAO-steered international programme for the destruction of obsolete pesticides (Stockholm Convention)
