C-Crete Technologies Awarded $2 Million by the US Department of Energy to Supercharge its Cement-Free Carbon-Negative Concrete Product
Addition of CO2 as a diluted gas from industrial waste sources or the air would turn C-Crete’s concrete into a carbon-negative building material
SAN LEANDRO, Calif. /PRNewswire/ — C-Crete Technologies is developing a method for using carbon dioxide captured at industrial sources or from the air as an ingredient in its cement-free concrete, in work accelerated by a $2 million funding from the US Department of Energy.
The DOE funding will help propel C-Crete’s already eco-friendly product into the exceptional category of carbon-negative building materials, possibly the first pourable, ready-mix concrete product to achieve this longtime goal of the industry.
Our pourable cement-free carbon-negative concrete not only mitigates carbon emissions but helps reversing climate change

The CO2 incorporated into the product – whether captured from the air as the concrete cures or from industrial point sources – could be used in a diluted form, eliminating the costly step of separating it from other gases. Once mineralized in the concrete, the diluted CO2 would make the new material stronger, tougher and more durable than conventional concrete.
At the core of C-Crete’s innovation lies its patented high-performance, cement-free binder technology that uses different local materials as feedstocks. C-Crete’s binder produces almost no CO2 in its manufacturing and continues to absorb it from the air over time. Its scalability and cost-parity with conventional cement make it a viable alternative to ordinary Portland cement – a notorious contributor to global CO2 emissions.
The DOE’s support for C-Crete’s work underscores the profound impact that innovative approaches can have in the battle against carbon emissions.
“We are committed to crafting a cement-free, ready-mix, carbon-negative concrete that doesn’t just mitigate carbon emissions but actively contributes to reversing climate change,” says Rouzbeh Savary, Ph.D., founder and president of C-Crete Technologies. “Our aim is nothing short of revolutionizing this hard-to-abate, carbon-heavy sector of the construction industry.”
“Concrete is one of the most difficult materials to address within the construction industry because the way it is used often precludes other sustainable strategies such as re-use and effective recycling,” says Stuart Macalister, technical design lead at Heatherwick Studio, an international award-winning architecture firm based in London. “C-Crete are pioneering significant reductions in the embodied carbon of concrete and their continued research into alternative techniques to avoid over dependence upon a single material source, is both savvy and inspiring.
“C-Crete’s sequestration of CO2 into cast-in-place concrete is another aspect with huge potential. The consensus amongst climate scientists is that even if we do everything else right to reduce emissions, the world still needs to remove gigantic amounts of CO2 from the atmosphere. Direct-air capture of CO2 is very expensive currently, so other methods, such as those being developed by C-Crete, are vitally important,” says Macalister.
“We need to do testing to get the use of next-generation materials like C-Crete’s right, and that requires early adopter field trials,” says Donald Davies, a developer and structural engineer with 33 years in the business, whose building in Seattle was the site of C-Crete’s first commercial pour. “It’s exciting to be a part of helping C-Crete on this important next step forward.” Davies is also chair of Building Transparency, a nonprofit dedicated to enabling the building industry to address embodied carbon’s role in climate change.
About: C-Crete Technologies is a leading materials science company committed to inventing, building and scaling up the next generation of infrastructure materials with ultra-low or negative CO2 footprints. With a relentless focus on environmental stewardship and technological innovation, C-Crete aims to address the global challenges of climate change while delivering superior infrastructure materials at scale.

Amtrak’s Return to Phoenix: A Promising Step Towards Improved Connectivity
“Amtrak’s return to Phoenix brings hope for improved connectivity and economic growth, linking Arizona’s largest cities by passenger rail. #TransportationRevival”


The Revival of Amtrak’s Sunset Limited Train Line:
Amtrak’s Sunset Limited train line, which currently operates between Los Angeles and New Orleans, plays a vital role in this project. By routing the Sunset Limited through Phoenix, the nation’s largest city without intercity passenger train service, Arizona aims to bridge the gap in its transportation infrastructure. Currently, the train has stops in various states, including California, Arizona, New Mexico, Texas, and Louisiana. However, it falls short of reaching Phoenix, with Maricopa being the nearest stop, approximately 40 miles to the south. The reintroduction of Amtrak service to Phoenix would mark the revival of a rail connection that was discontinued in 1996.
Benefits for Arizona:
The Phoenix-Tucson passenger rail project holds immense promise for Arizona, both economically and environmentally. Representative Stanton, a strong advocate for this initiative, highlighted the advantages during a House Transportation and Infrastructure Committee hearing. Connecting the state’s two largest cities by passenger rail would enhance accessibility, productivity, and economic opportunities for the communities along the route. By easing congestion and reducing air pollution caused by traffic on Interstate 10, this rail service would be a sustainable alternative for commuters and travelers.
Economic Opportunities and Regional Development:
As numerous communities across the country have experienced, the introduction of passenger rail brings a wave of new economic opportunities. Arizona, thus far, has been unable to tap into these benefits. However, with the allocation of federal funds and the state’s contribution of $3.5 million, the planning phase for the Phoenix-Tucson rail project is underway. This phase includes developing a comprehensive cost estimate, addressing route logistics, and evaluating the necessary infrastructure enhancements. By investing in this much-needed transportation link, Arizona can unlock the potential for increased tourism, job growth, and business development in the region.


The allocation of federal funds for reestablishing passenger rail service between Phoenix and Tucson marks a significant milestone in Arizona’s pursuit of improved transportation connectivity. With strong local and state support, the Phoenix-Tucson rail project has the potential to revolutionize mobility within the state. By linking the two largest cities, this initiative will foster economic growth, alleviate traffic congestion, and contribute to a greener and more sustainable future. As the planning phase progresses, Arizona stands poised to embrace the economic opportunities and enhanced quality of life that passenger rail service can bring.
