Presentation: about the ECT group


Activities of the ECT Group

The companies of the ECT Group re-use, recycle, develop and upcycle as part of the urban metabolism and circular economy.

  • ECT's business is the development of sites by upcycling inert soil and treating polluted soil and other spoil from construction and tunnelling sites.
  • BIOPEDE's work is the upcycling of organic waste.

ECT's growth is based on a strategy of 'circular economy': Re-using excavated soil from urban work sites to work with communities and local authorities on projects of sustainable, collaborative development.

To provide a structure for this, ECT has developed various centres of expertise. The division responsible for the management of excavated soil meets the need for environmental engineering and the requirement for traceability on the part of the construction & public works sector and the Grand Paris Express. The division dealing with design and implementation of land-use developments offers, to communities and local authorities, useful projects based on the upcycling of excavated soil. A division dealing with the operation and development of the sites completes the set of ECT's core activities.

ECT holds ISO 14001 for the Development and Operations departments. All the operational sites are certified to ISO 140001.

Since 2016, Laurent Mogno has been the chairman of ECT.
