France: Hoffmann Green Technologies has partnered with France-based CSBT Environnement, a company specialising in the recovery of scallop shells. The shells are byproducts of the fishing industry, and are collected and processed using a mechanical fine grinding method to yield calcium carbonate with 99% purity suitable for the construction sector. Hoffmann Green will incorporate the material into its 0% clinker cement.
Julien Blanchard and David Hoffmann, cofounders of Hoffmann Green Cement Technologies, said "This partnership demonstrates our ability to incorporate alternative raw materials from the circular economy without compromising the performance of our 0% clinker cements. The utilisation of marine calcium developed by CSBT is fully aligned with our decarbonisation strategy and opens up new possibilities for the production of binders with a very low carbon footprint."
