Urban Soil: An asset for the sustainable city

A new EIVP / ECT conference: “Urban Soil: an asset for the city of tomorrow”

Within the context of the business chair “Upcycling Soil from Urban Construction Sites”, the École des Ingénieurs de la Ville de Paris (the City of Paris School of Engineering) and ECT organised a new conference on 22 and 23 June, in partnership with the École Nationale Supérieure du Paysage (the national landscape gardening school at Versailles) and with the participation of Cycle Terre. It was an opportunity for ECT and the EIVP to deepen and communicate a thought process which places soil at the heart of various aspects of the current debate on the sustainable city: 

  • As a driver for the rehabilitation of derelict sites
  • As a defining element for new landscape in the regions
  • As a construction material that respects the environment
  • As an essential element in the urban integration of green spaces of varying kinds, and of biodiversity.

A multi-disciplinary approach to the benefit of the sustainable city

These different aspects suggest that urban soil can turn a new and positive approach into reality. They are part of the policy of the sustainable city. With the twin approaches of economising on resources and re-using materials in a way that respects the environment. A wide variety of theoretical and historical approaches were considered, and national, international and Île-de-France examples given by way of illustration.

These four half-days advocated the development of a multidisciplinary approach combining urban engineering, ecological engineering, town planning and landscaping.
