From technical expertise to innovation

The SinteoLab enables me to challenge my areas of expertise by providing a cross-functional vision of Sinteo's different businesses.
Antoine Vieillard, engineer and member of the SinteoLab Committee
In 2024, 12 subjects were studied in detail. For example, the lab focused on the production of an FDES (Fiche de Déclaration Environnementale et Sanitaire).
Having collected data at the factory, we can now calculate the environmental footprint of a building material.
We have put innovation back at the heart of our processes. This FDES enables us to develop our materials expertise, which enhances our building offer. In fact, we've already sold our first FDES mission!Julie Vinson, General Manager, Sinteo
