California Startup Pioneers Breakthrough in Reducing Concrete’s Carbon Footprint

by Anna

Concrete, a staple of modern construction, also stands as a significant contributor to climate change due to its carbon-intensive production process. However, a California-based startup, Fortera, is spearheading a revolutionary technology aimed at slashing carbon emissions associated with cement production. This breakthrough not only addresses environmental concerns but also promises economic viability and scalability on a global scale.


Fortera’s innovative approach intercepts carbon dioxide emissions from cement kilns, redirecting them to produce additional cement. This technology, operationalized at the CalPortland facility in Redding, California, marks a significant milestone in the quest for sustainable concrete production. The startup’s CEO, Ryan Gilliam, envisions a future where their solution becomes ubiquitous, seamlessly integrating with existing cement plants worldwide.


Initially, Fortera’s technology will augment a portion of CalPortland’s cement production, reducing carbon emissions by approximately 10%. However, the demand for higher blend ratios, capable of achieving carbon reductions of 40-50%, signals a promising market trajectory. Moreover, Fortera offers a pure product boasting a remarkable 70% reduction in carbon emissions, underscoring its potential as a game-changer in the construction industry.

Fortera’s journey traces back to its predecessor, Calera, which pioneered carbon dioxide conversion into cement over a decade ago. Building upon this foundation, Gilliam and his team launched Fortera in 2019, leveraging their expertise to drive innovation in sustainable cement production.

Unlike other low-carbon concrete initiatives, Fortera’s technology integrates seamlessly with existing cement manufacturing processes, presenting a practical and economically competitive solution. Its compatibility with established industry practices positions it as a frontrunner in the race to combat climate change without compromising operational efficiency.

As global efforts intensify to mitigate the environmental impact of concrete production, Fortera’s breakthrough holds immense promise. Regulatory initiatives, such as California’s mandate to reduce cement industry emissions, underscore the urgency and importance of adopting sustainable solutions.

Concrete’s indispensability in modern society necessitates comprehensive solutions that balance environmental stewardship with practicality and durability. Fortera’s technology offers precisely that—an innovative approach that not only reduces carbon emissions but also upholds the structural integrity and functionality of concrete.

As Fortera advances towards broader adoption and regulatory approval for its 100% ReAct product, the implications for global sustainability are profound. With the construction industry poised to play a pivotal role in combating climate change, Fortera’s technology represents a beacon of hope for a more sustainable future—one where concrete’s environmental footprint is significantly diminished, without compromising its essential role in shaping the world we live in.
