Hoffmann Green Cement Technologies and E.C.B.L. Strengthen Their Partnership to Accelerate Decarbonized Construction in Charente-Maritime

08 Dec 2025 08:00 CET

Hoffmann Green Cement Technologies (ISIN: FR0013451044, Ticker: ALHGR) (“Hoffmann Green Cement” or the “Company”), an industrial player committed to the decarbonation of the construction sector that designs and markets innovative cold produced, clinker-free cements, announces the intensification of its collaboration with Entreprise de Construction et Bâtiment du Littoral (E.C.B.L.), a general construction company based in Rochefort (17).

Three years of successful collaboration

Since the signing of their first partnership agreement in December 2022, the two companies have successfully collaborated on several key projects in Charente-Maritime, including the La Rochelle Departmental Fire and Rescue Service and “Les Hauts de Royan,” a large-scale housing renovation and construction program.

These achievements have demonstrated the performance and reliability of Hoffmann Green solutions on E.C.B.L. construction projects. Building on these achievements, the two partners are taking a new step forward by strengthening their cooperation for the years to come.

A commitment to low-carbon construction sites across the region

Today, the partners are strengthening their collaboration with a new three-year contract and increased volumes. Hoffmann Green will supply increased quantities of its 0% clinker-free cement to E.C.B.L. to support exceptional structural work and renovation projects, mainly in Charente and Charente-Maritime. These projects include the construction of collective housing, industrial, public, tertiary, and office buildings, as well as major renovation work contributing to the preservation and enhancement of the built heritage.

This strengthening is also based on the close geographical proximity between the two players, promoting regional synergies and reducing logistical impacts. Together, the two players contribute to local dynamism and innovation in favor of the low-carbon transition of the building sector.

Julien BLANCHARD and David HOFFMANN, Co-founders of Hoffmann Green Cement Technologies, say: “This strengthened partnership with E.C.B.L. illustrates the momentum that has been building for several years to radically transform construction methods in our regions. The results achieved on key projects such as the SDIS in La Rochelle and Les Hauts de Royan demonstrate that effective low-carbon solutions exist today and can be successfully integrated into all types of projects. We are proud to support a committed regional player and to work together to accelerate the sector's environmental transition.”

Jean Pierre CHAMBET, President of E.C.B.L., adds: “For three years, the use of Hoffmann Green cements has proven to be a major asset in combining technical performance, innovation, and reducing our carbon footprint. The strengthening of this partnership demonstrates our desire to go further in sustainable construction, serving local communities, residents, and businesses in the region. The proximity between our structures reinforces the consistency of this local, ambitious, and responsible approach.
