France: Hoffmann Green Cement Technologies announces the launch of H-CLAY®, a new technology that enables the cold processing of clay into a co-product for use in the formulation of 0% clinker cements. This technology is based on a process for cold-processing clay, without resorting to traditional calcination or flash-calcination processes and their associated CO₂ emissions. H-CLAY enables the recovery of various types of clay to be integrated as a co-product in the formulation of low-carbon cements, similar to slag in some of the company’s 0% clinker cements.
Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies, said "The launch of H-CLAY marks a new milestone in Hoffmann Green's technological history. Having demonstrated that it is possible to mass produce and market high-performance clinker-free cements, we are now breaking new ground with the cold processing of clay, without calcination or flash-setting. This innovation perfectly illustrates our ambition: to develop disruptive technologies able to significantly reduce cement's carbon footprint, while meeting the technical requirements of the construction market.”
