Prometheus Materials Adds Cement, Concrete and Biocement Leaders to Support Next Phase of Commercial Scale-Up
Filiberto Ruiz and Alan Wessel join the Board of Directors; Brian Chapman, PhD, joins as Director of Technology
LONGMONT, Colo., Sept. 30, 2026 /PRNewswire-PRWeb/ — Prometheus Materials, a cement technology company making low-carbon and carbon-negative cement accessible across the cement and concrete industries, today announced the appointment of Filiberto Ruiz and Alan Wessel to its Board of Directors and Brian Chapman, PhD, as Director of Technology.
The three appointments bring together deep experience in cement manufacturing, concrete commercialization and biocement technology as Prometheus Materials advances the commercial scale-up of ProZERO™, its concentrated GWP-reducing supplemental blend designed to replace supplemental cementitious materials (SCMs) such as fly ash and slag.
Prometheus technology is already being deployed in real-world projects for six of the datacenter hyperscalers demonstrating its ability to bring low-carbon—and carbon-negative—cement technology into existing concrete production at commercial scale.
“Prometheus has reached a stage where scaling successfully requires more than a strong technology. It requires a deep understanding of how this industry operates,” said Loren Burnett, President, CEO and Co-founder of Prometheus Materials. “Filiberto, Alan and Brian bring complementary experience across cement, concrete and materials science—from technical validation and production to customer adoption and repeat use.”
Filiberto Ruiz brings nearly four decades of cement and construction materials leadership. He previously served as President and CEO of Votorantim Cimentos North America and earlier served as President and CEO of Holcim US and Aggregate Industries US. He has also chaired the Portland Cement Association and was a Member of the Executive Board of the National Ready Mix Concrete Association (NRMCA), giving Prometheus additional experience at the highest levels of cement manufacturing, industry partnerships and market adoption.
“The cement and concrete industries are being asked to meet competing demands at once: build more, use more cement, lower carbon, and do it within existing operational and economic realities,” said Ruiz, Chairman of the Board of Prometheus Materials. “Prometheus offers a practical path to do all four at scale.”
Alan Wessel brings more than 35 years of construction materials experience, including leadership of Thomas Concrete’s U.S. operations and senior roles at Vulcan Materials Company. Alan also served on the Executive Committee and was a Board Member of the National Ready Mix Concrete Association (NRMCA).
His background spans ready-mix operations, manufacturing scale, customer adoption and the commercialization of new construction materials.
“The question is no longer simply, ‘Does the science work?’ It’s how we turn this into a significant construction materials business,” said Wessel. “Low-carbon concrete is moving from a sustainability specialty toward a mainstream ingredient, and Prometheus is at exactly the stage where disciplined commercialization and execution can make the difference.”
Brian Chapman, PhD, joins Prometheus with deep experience in materials science and novel cement technologies. Previously with Biomason, Chapman has helped advance first-of-their-kind biocement technologies from research through pilot and full-scale production.
Together, the appointments significantly strengthen Prometheus across the interconnected disciplines required to bring a new cement technology to scale: materials science and technical performance, cement-industry integration, and real-world concrete commercialization.
About Prometheus Materials
Prometheus Materials is a cement technology company commercializing low-carbon and carbon-negative cement solutions across the cement and concrete industries.
Its flagship product, ProZERO™, is the only product on the market capable of achieving carbon-negative results, at commercial scale. ProZERO™ is a concentrated GWP-reducing supplemental blend that replaces supplemental cementitious materials (SCMs) such as fly ash and slag in concrete mix designs. Designed for real-world use, ProZERO™ integrates into existing ready mix concrete production processes without requiring changes to infrastructure or operations.
Prometheus technology is already being deployed in projects for six datacenter hyperscalers, putting its low-carbon cement technology to work in some of the world’s most demanding construction environments.
By combining significant carbon reduction with supply-chain flexibility and compatibility with existing production systems, Prometheus Materials is advancing scalable solutions for more sustainable construction.
