Hoffmann Green announces the launch of H-CLAY

With H-CLAY, Hoffmann Green is taking a major step forward in its innovation strategy. This technology is based on a unique process for cold-processing clay, without resorting to traditional calcination or flash-calcination processes, which are highly energy-intensive and emit CO₂.

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 Hoffmann Green 0% clinker cements. This technological breakthrough paves the way for a new generation of cements, designed to meet the requirements of structural concrete. It combines technical performance, durability, energy efficiency, and a reduced environmental footprint, while expanding the range of raw materials that the Company can utilise.

Hoffmann Green now has a new industrial tool that enables it to tap into a vast global supply of raw materials, while limiting the energy requirements associated with their processing.

A strategic innovation driving the industrialisation of low-carbon cement

Since its founding, Hoffmann Green has pursued a process of constant innovation, developing sustainable solutions and co-products that are transforming the cement market. Today, the company has established itself as a key player in an industry that had seen no disruptive innovation for over 200 years.

H-CLAY® technology strengthens Hoffmann Green’s ability to design solutions tailored to the current challenges of the construction sector: reducing CO₂ emissions, conserving resources, industrialising more efficient processes, and developing materials compatible with the requirements of structural concrete. It also serves as a strategic lever for diversification, enabling the Company to access new market segments and expand its areas of application.

This new technology demonstrates Hoffmann Green’s continued technological leadership and R&D momentum in developing new 0% clinker industrial processes. It aligns with the Company’s goal of developing an expanded portfolio of innovative, high-performance, and decarbonised cements to reach six innovative 0% clinker cements by 2030.

To date, Hoffmann Green’s technology portfolio includes four innovative technologies designed for all markets in the construction sector: H-UKR, a technology based on alkali-activated slag; H-IONA, supersulfated cement; H-EVA, an alkali-based ettringite technology; and H-P2A, a geopolymer technology.

Julien Blanchard and David Hoffmann, Co-founders of Hoffmann Green Cement Technologies, say: “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 reducing cement’s carbon footprint, while meeting the technical requirements of the construction market. H-CLAY strengthens our technological lead and confirms our unique position in the decarbonized cement industry.”
