Reclamation of soil from the Toulouse metro with a temporary consortium of companies

BOUYER LEROUX, EDILIANS and TERREAL, leaders in the terracotta industry in France, have responded to a call for expressions of interest launched by TISSEO-INGENIERIE for the recovery of excavated material from the third line of the Toulouse metro and its connection to Line B.
With sites in the immediate vicinity of the construction site, the three companies have joined forces in a temporary joint venture (GME) in order to experiment with the recovery of excavated materials by integrating them into the manufacturing process of terracotta materials.

Actions

TISSEO-INGENIERIE, delegated project manager representing the Syndicat Mixte des Transports en Commun de l'agglomération toulousaine, launched this collaborative procedure with a view to issuing invitations to tender for the recovery of 2.8 million m3 of soil excavated from underground structures in compliance with environmental regulations.

Faced with the environmental challenges of this major project, the companies BOUYER LEROUX, EDILIANS and TERREAL have pooled their capacities to offer :

- the recovery of the material by its introduction into terracotta building materials for the shell and roofing, in accordance with the Law on the fight against waste and the circular economy (Law n° 2020-105 of 10 February 2020);

- recovery as quarry backfill.

The maximum distance of 10km from these sites (tile factory and brickworks) to Colomiers station will also ensure a limited carbon footprint in terms of transport.

Terreal sponsors the association Le Printemps de Septembre

In 2021, TERREAL is sponsoring the association "Le Printemps de Septembre" to build an ephemeral brick pavilion at the Institut Supérieur des Arts et Design de Toulouse for the 30th edition of the "Le Printemps de Septembre" festival in Toulouse. With a donation of more than 2,300 bricks, TERREAL wished to support cultural and artistic initiatives as well as to participate in this educational project where specialised students learned how to build the structure. After the event, the bricks were collected by training centres in order to give them a second educational life.

Circular economy, study with ENSAL for the recovery of construction site soil

Since 2015, TERREAL has regularly offered study topics to young architectural students at ENSAL, whose mission is to experiment and prototype with materials for architectural projects. Nearly 5 projects by some thirty students have been presented in this way, two of which have led to the filing of patents. In 2021, Terreal proposed to the Ecole Nationale Supérieure d'Architecture de Lyon (ENSAL) a study partnership as part of its students' curriculum. This project, in line with the Group's commitment, highlights the interest of using these soils in combination with clay products, such as the Brique Hauteur d'Etage.
