At the heart of the action, on the Moissy-Cramayel site in Seine-et-Marne (77), Laurent Mogno, President of ECT, met Franck Boittiaux from Mat Environnement (Construction Cayola group). The meeting offered the journalist an opportunity to visit the new planted promenade and arboretum, which will be inaugurated in June 2019. And to show him around the summit plateau, which will continue to receive soil from neighboring construction sites for several months to come. It was also an opportunity to explain the different ECT professions: manager of excavated soil on behalf of its construction and public works customers designer of projects reusing

What will become of the excavated soil from the Grand Paris Express? asks Clémence Barral Long-term management? What is to be done with the excavated soil from the stations and the tunnel boring machines? Public authorities directly support certain projects. Others, such as “Les Yeux du Ciel”, are the brainchild of Antoine Grumbach and ECT. Read the article

Laurent Mogno, CEO of ECT: “Excavated soil from the Grand Paris Express is only part of the annual volume”. Interview by Rémi Cambau, for Cadre de Ville, Friday, June 21, 2019 [The leading soil recycling operator in the Paris region claims to handle between 12 and 15 million tonnes per year. “We’re a volume player,” sums up ECT’s CEO soberly, before adding: “In two and a half years, we find a job equivalent to all the soil that the Grand Paris Express will produce in twelve years.”]

RECYCLE INERT SOIL AND GREEN WASTE TO CREATE FERTILE SOIL As part of these reflections on urban metabolism, Plaine Commune is piloting a new call for projects. It is entitled “Building new recycling channels for building materials together”. The aim of ECT’s fertile substrate production is twofold: to recycle inert soil from construction sites and to recycle green waste compost. This mixture enables the rapid creation of technosols. PRESERVE TOPSOIL, STOP ITS IMPORTATION Topsoil is a natural resource that must be preserved. It is important to keep imports to a minimum. ECT’s fertile substrate represents a 100% eco-responsible alternative: Produced

Simon Boudvin, artist and teacher at ENSP, led a first EARTHWORKS workshop in partnership with ECT. The aim of the workshop? 4 days to design and create a work of art using 1000 m3 of soil. For this workshop, attended by some thirty students from the Ecole de Paysage de Versailles, ECT provided a site, inert soil, a bulldozer and its operator. What’s at stake? They are many and varied: Rediscovering the conceptual roots of Land Art Understanding this landscape rebuilt with inert soil Creating a landscape-scale object The gamble paid off! A new landscape appears! Photo credit Simon Boudvin

Interview “We need to promote the reuse of inert soil excavated from building sites” (Laurent Mogno, ECT) AUA – Paris – Friday, May 17, 2019 – Interview n° 146743 [We need to promote the reuse of excavated inert soil. The recovery of this material from construction sites is noble. It’s not recycling. Soil reuse objectives vary from site to site, depending on local issues. In terms of landscaping, the field of possibilities is immense. Our aim is to develop a circular economy for excavated soil, so that we can design useful developments that contribute to local dynamics,” explains Laurent Mogno,

Artificial hills on the ECT Moissy-Cramayel site The town hall of Moissy-Cramayel (Seine-et-Marne) will soon be inaugurating a park created entirely from recycled soil. What to do with soil excavated from construction sites ? In a few weeks’ time, the town hall of Moissy-Cramayel (Seine-et-Marne) will inaugurate a park created entirely from recycled soil. In twenty years or more, as the zones are depleted, the gypsum galleries exploited by Placo in the Ile-de-France region will be filled with the same soil. It makes good sense to use the spoil excavated from all construction sites to fill in or backfill. This

Stirring up shovels and earth By Sibylle Vincendon – April 12, 2019 at 11:24 am [Each week, a story about towns, villages and urban issues. Today, the fate of tons of soil moved to plant construction sites. Large volumes. It’s the story of a guy who digs a hole. A second guy comes along and asks, “And where are you going to put the dirt?” And the first guy replies, “In another hole.” On any building or public works site, the hole is the first operation to be carried out. But as there’s no question of digging a second one
