Hoffmann Green Achieves U.S. Milestone With First 0% Clinker Concrete Construction Project
Hoffmann Green Cement Technologies has reached a significant milestone in its international expansion with the completion of its first construction project in the United States using its innovative 0% clinker concrete. The project represents an important step in the company’s efforts to establish its low-carbon cement technologies in the American construction market and provides the business with a first concrete reference in the region.
Hoffmann Green Cement Technologies, listed on Euronext Paris under the ticker ALHGR, develops and markets innovative cements produced without clinker through a low-temperature manufacturing process. Its approach is designed to help reduce the carbon footprint associated with conventional cement production, making the technology particularly relevant as the construction industry looks for ways to lower emissions while maintaining the performance required for infrastructure and building projects.
The newly completed U.S. project was carried out for Marquis INC, an American industrial group with activities spanning low-carbon solutions, energy, biofuels, agriculture and infrastructure. The collaboration gives Hoffmann Green an opportunity to demonstrate that its 0% clinker technology can be implemented in a U.S. industrial environment and meet the requirements of an operational construction project.
First U.S. Project Establishes a Local Reference
The project for Marquis INC involved the construction of an industrial platform in Illinois. The location is strategically positioned near the borders of Indiana and Missouri, placing the project within an important industrial region of the United States.
For Hoffmann Green, the completion of the platform goes beyond a single construction project. It creates an initial operational reference that can support the company’s efforts to develop commercial opportunities across the wider U.S. market.
Marquis INC is a family-owned company with almost five decades of experience in industrial activities. It is also a major U.S. producer of renewable ethanol, with annual production exceeding 1.5 billion liters. In addition to renewable ethanol, the group has developed businesses covering proteins and animal nutrition, sustainable fuels, industrial alcohol and industrial infrastructure.
The partnership therefore brings together two companies with complementary interests in lower-carbon industrial development. For Hoffmann Green, working with an established industrial customer provides an opportunity to demonstrate its technology under real project conditions rather than solely through laboratory testing or pilot-scale applications.
Moving From Technology Development to Operational Deployment
The Illinois project marks what Hoffmann Green describes as the beginning of a new operational phase for its activities in the United States. Establishing a first project in the country is an important part of the company’s international development strategy because it provides a tangible demonstration of how its cement technologies can be integrated into local construction practices.
The company’s 0% clinker approach is focused on replacing traditional clinker-based cement technology. Conventional cement manufacturing relies heavily on high-temperature processes associated with significant carbon emissions. Hoffmann Green’s alternative production model is designed around clinker-free cement manufactured through a cold process, supporting the company’s broader objective of decarbonizing construction.
According to Hoffmann Green, its technologies have already progressed through important stages of development and certification. The company says it has obtained ASTM C1157 certification in the United States and is continuing qualification work under American standards. Its next major objective includes obtaining AC 529 approval.
That approval is strategically important because it would expand the range of applications that can be addressed by Hoffmann Green’s technologies in the U.S. market. The company aims to move beyond specific project applications and ultimately serve a broader range of concrete construction requirements.
U.S. Construction Market Offers Significant Potential
The United States represents an attractive growth opportunity for Hoffmann Green because of the scale of its construction and infrastructure sectors. Large investments in industrial facilities, energy infrastructure and other major construction projects are creating potential demand for materials capable of reducing project-related carbon emissions.
At the same time, developers, industrial companies and construction stakeholders are increasingly examining the environmental impact of building materials. Cement and concrete are central to this discussion because of their extensive use in infrastructure and construction.
Against this backdrop, Hoffmann Green believes its 0% clinker technologies could address a growing market requirement. The successful completion of the Illinois project gives the company an early reference point from which to demonstrate the practical application of its technology to potential customers and partners.
The company’s U.S. expansion also builds on a broader international strategy. Rather than limiting its activities to its home market in France, Hoffmann Green is seeking to introduce its low-carbon cement technologies into markets where construction activity and demand for sustainable materials offer significant development opportunities.
Certification Remains a Key Priority
While the first U.S. project represents a major achievement, regulatory approval and qualification remain central to Hoffmann Green’s expansion plans. The company is continuing discussions and technical work with the relevant organizations to ensure its products comply with applicable U.S. requirements.
The planned AC 529 approval could be particularly significant. By broadening the applications for which its technologies are accepted, the certification would allow Hoffmann Green to pursue a wider range of construction opportunities across the United States.
This regulatory progress, combined with the company’s first completed U.S. project, could provide an important foundation for future commercial growth.
A Strategic Step for Low-Carbon Construction
Thomas Atkinson, Hoffmann Green’s Head of International Business, said the completion of the first 0% clinker concrete project marks the company’s entry into a new phase of its U.S. development. He highlighted the collaboration with Marquis INC as an important demonstration of the technology’s ability to operate within the American market and described the project as a strong reference for future expansion.
The achievement comes at a time when the construction industry is under increasing pressure to reduce embodied carbon and find alternatives to conventional high-emission materials. For Hoffmann Green, the Illinois industrial platform provides more than a completed construction site: it represents a practical demonstration of its clinker-free cement technology in the United States.
As the company continues its certification and qualification efforts, the first U.S. project could become a foundation for broader adoption of 0% clinker concrete. With major infrastructure investment, industrial development and increasing interest in lower-carbon construction materials, Hoffmann Green is positioning its technology to pursue a larger role in the evolving U.S. sustainable construction market.
