What happens to the Grand Paris Express land? A France Inter podcast

The France Inter program “La Terre au Carré” broadcast a series of reports by journalist Juliette Prouteau. This documentary mini-series takes a broad look at excavated soil from the Grand Paris Express construction sites.

The project represents some 45 million tonnes of excavated material. In a series of reports, the journalist sheds light on the management and fate of this spoil.

  • Episode 1: the Grand Paris Express construction site, with a visit to the tunnel of the future line 16.
  • Episode 2: heading for the ECT Center for biological treatment of hydrocarbon-impacted soil, located in La Courneuve (93). The journalist explains the treatment process used to biologically clean up the impacted land.
  • Episode 3: a trip “to the center of the earth” with a visit to Europe’s largest quarry at Baillet-en-France (95). The galleries are backfilled with some of the GPE’s soil to make them safer.
  • Last episode: discovering the “Cycle Terre” project, in which ECT is now a partner. How can raw earth building materials be made from excavated soil?
