Hoffmann Green Cement Technologies has launched H-CLAY®, a groundbreaking technology that enables the cold processing of clay into a co-product for use in the formulation of 0% clinker cements. This innovation eliminates the need for traditional calcination or flash-calcination processes, which are highly energy-intensive and emit CO₂. By integrating various types of clay as a co-product, Hoffmann Green aims to expand its range of raw materials while reducing the environmental footprint of its cement production.
The H-CLAY® technology is designed to meet the requirements of structural concrete, combining technical performance, durability, and energy efficiency. It allows Hoffmann Green to tap into a vast global supply of raw materials without the high energy costs associated with thermal processing. This advancement aligns with the company's strategy to industrialize low-carbon cement and diversify its market segments.
Strategic innovation and portfolio expansion
Hoffmann Green's technology portfolio now includes five innovative solutions for the construction sector. The addition of H-CLAY® strengthens the company's ability to address challenges such as reducing CO₂ emissions, conserving resources, and developing materials compatible with structural concrete. The company targets the development of six 0% clinker cements by 2030.

Leadership perspective
Julien Blanchard and David Hoffmann, Co-founders of Hoffmann Green Cement Technologies, emphasized the significance of this launch. They stated that H-CLAY® marks a new milestone in the company's technological history, demonstrating its ability to mass-produce high-performance clinker-free cements. The innovation reinforces Hoffmann Green's position as a leader in the decarbonized cement industry by significantly reducing the carbon footprint of cement while meeting technical market requirements.
Founded in 2014 and based in Bournezeau, France, Hoffmann Green Cement Technologies designs, produces, and distributes low-carbon cements with a carbon footprint five times lower than traditional cement. The company operates two production units and plans a third factory in the Rhône-Alpes region, scheduled for 2027-2028, to reach a total capacity of around 1,000,000 tons per year.
How will the introduction of H-CLAY® influence Hoffmann Green's competitive positioning against traditional cement manufacturers and other low-carbon cement innovators?
What are the potential cost implications of scaling H-CLAY® production, and how might it impact the pricing of Hoffmann Green's 0% clinker cements?
