Hoffmann Green and CSBT Environnement Are Processing Waste Scallop Shells Into a Resource for the Production of 0% Clinker Cement
CHAILLÉ-SOUS-LES-ORMEAUX, France, August 26, 2026--Regulatory News:
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 a partnership with CSBT Environnement, a French company specializing in the recovery of scallop shells.
From Scallop Shell Waste to a Resource for Decarbonized Cement
Each year, the fishing industry generates significant volumes of scallop shell waste, for which there is no large-scale treatment solution. The ban on landfilling and incineration makes this a major challenge for coastal regions. CSBT Environnement provides a concrete solution for upcycling, from collection to processing. The cockles are processed using a mechanical fine-grinding method, without the addition of chemicals. This process yields marine calcium carbonate with 99% purity, reduced to a very fine particle size, suitable for demanding industrial applications, particularly in the construction sector.
In this context, Hoffmann Green will incorporate this raw material into its 0% clinker cements, transforming a waste product with no market outlet into a high-value-added resource. This approach contributes to the production of binders with a very low carbon footprint, while positioning 0% clinker cement within a concrete circular economy framework.
An Innovative Industrial Partnership
The integration of marine calcium carbonate into the formulation of Hoffmann Green's 0% clinker cements is the result of significant innovation efforts aimed at adapting a bio-based material to meet the technical requirements of Hoffmann Green's 0% clinker cements. Building on these achievements, CSBT will ensure a steady supply of raw materials to Hoffmann Green, establishing a sustainable value chain between the two partners.
This partnership is based on the complementary strengths of two companies committed to transforming industrial models to reduce environmental impact by developing concrete, industrially scalable solutions through innovation.
Julien BLANCHARD and David HOFFMANN, co-founders of Hoffmann Green Cement Technologies, stated: "This partnership demonstrates our ability to incorporate alternative raw materials from the circular economy without compromising the performance of our 0% clinker cements. The utilization of marine calcium developed by CSBT is fully aligned with our decarbonization strategy and opens up new possibilities for the production of binders with a very low carbon footprint."
