Hoffmann Green announces the launch of H-CLAY®, a groundbreaking new technology designed to enhance the value of clay
Hoffmann Green announces the launch of H-CLAY®, a groundbreaking new technology that enables the cold processing of clay into a co-product for use in the formulation of 0% clinker cements.
H-CLAY®: a groundbreaking new technology for cold-processing 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 utilize.
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 industrialization 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, industrializing 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 decarbonized cements to reach six innovative 0% clinker cements by 2030. 2
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.
