FROM GRAND PARIS TO PARIS EN GRAND

This is the vision of “a new model of global metropolis” developed by Roland Castro in the report submitted to the French President. One of our ambitions is to extend Paris beyond its historical boundaries, while building a “metropolitan oasis”.

This is the background to architect and urban planner Antoine Grumbach’s contribution, in which he asserts that inert soils are a material of the circular economy” and that their reuse is one of the challenges of a concerted development of “Greater Paris”.

As a major player in the reuse of inert soil, ECT is fully committed to this approach.
