Fortera and MLC have signed a development agreement to build what the companies describe as the first full-scale commercial facility producing ReAct cement, designed to make more than 300,000 tons of the low-carbon material annually.
Why it matters: The project would add domestic cement production capacity in the United States, where imports currently make up roughly a quarter of annual cement consumption — a real supply-chain gap, not just an environmental pitch. It’s also a specific test of whether carbon-capture cement technology can actually scale to commercial volumes, rather than staying confined to pilot projects, by attaching it directly to an existing industrial producer’s operations instead of building standalone infrastructure from scratch.
Fast facts
- Companies: Fortera (carbon-capture cement technology) and MLC (limestone and lime manufacturer)
- Agreement: development deal for a full-scale commercial ReAct cement plant
- Target capacity: more than 300,000 tons of ReAct cement annually
- How it works: Fortera’s ReCarb technology captures industrial CO2 emitted during MLC’s high-calcium lime production and converts it directly into cement
- Product composition: ReAct cement is nearly 50% captured CO2 by weight, according to Fortera
- Standards: Fortera says ReAct cement has been extensively third-party tested and complies with ASTM standards
- Not yet disclosed: plant location, project cost, and construction timeline — the companies say more details will follow in the coming months
How the technology works
Fortera’s ReCarb process is designed to capture CO2 that would otherwise be released during MLC’s production of high-calcium lime, then convert that captured carbon directly into cement rather than storing or disposing of it separately. The result, Fortera says, is a cement product built to match traditional cement on the metrics customers actually care about — performance, cost, and manufacturability — while reducing the material’s environmental footprint.
Fortera says ReAct cement can be used either as a standalone product or blended with ordinary Portland cement, the conventional material it’s designed to compete with or supplement. The company also says the product has undergone extensive third-party testing and meets ASTM standards, though the announcement doesn’t name the specific testing organization involved — worth confirming directly before treating that claim as fully independently verified.
Why domestic cement production matters here
Roughly a quarter of the cement the U.S. consumes annually is currently imported, according to the companies’ announcement. A 300,000-ton annual facility wouldn’t close that gap on its own — global cement demand runs to roughly 4 billion tons a year — but it represents a concrete addition to domestic supply built around a lower-carbon production method, rather than simply more capacity of the same kind already being imported.
Fortera’s scaling strategy
The MLC partnership reflects a broader approach Fortera is taking to scale within a cement market that size: rather than building new standalone plants from the ground up, the company is partnering with established producers and attaching its capture-and-conversion technology to their existing feedstocks, infrastructure, and logistics networks.
Ryan Gilliam, CEO and co-founder of Fortera, said the MLC partnership gives the company “the opportunity to scale our production to meet demand that already exists,” and described the collaboration as a chance to learn from an established industrial partner rather than scale in isolation.
MLC is a global manufacturer of limestone and lime products, serving markets that include construction, chemicals, agriculture, and water and emissions treatment. The company operates one of the largest lime production facilities in the Americas, alongside a network of production and distribution sites across the U.S. and U.K.
Paul Hogan, CEO of MLC, framed the deal around the chemical overlap between the two companies’ core businesses: “Lime and cement are chemically similar businesses, and we’ve spent over a century perfecting our end of that process,” he said, adding that the partnership gives MLC “a real path to help decarbonize a hard-to-abate industry.”
What’s not yet known
The announcement doesn’t specify where the plant will be built, how much it will cost, or when construction or production might begin — Fortera and MLC say they plan to share additional project details in the coming months. Cement production is also a genuinely hard industry to decarbonize at scale, given the sheer volume the global market requires; a single 300,000-ton facility is a meaningful proof point for the ReCarb technology’s commercial viability, but it’s a small fraction of even U.S. cement demand alone.
Zoom out
Cement manufacturing is one of the more stubborn sources of global industrial CO2 emissions, and most low-carbon cement efforts to date have struggled to move past pilot scale specifically because matching traditional cement’s cost and performance at real production volumes is difficult. Fortera’s bet — attaching its technology to an established lime producer’s existing operations rather than building independent infrastructure — is a specific answer to that scaling problem, and this agreement is the first real test of whether it works at commercial volume rather than in a lab or demonstration facility.
