What Fortera does

Fortera is a US-based materials technology company founded in 2007 and headquartered in San Jose, California, that develops and commercializes low-carbon cement through its proprietary ReCarb process. The technology captures CO2 from cement and lime plant kiln exhaust and mineralizes it into vaterite, which matures into a calcite-based cementitious binder; Fortera states 44% of the resulting ReAct product is sequestered CO2 that would otherwise be emitted. Fortera monetizes through three complementary vectors: sale of ReAct Cement (a 100% Portland cement replacement) and ReAct Blend (a supplementary cementitious material), licensing/deployment of bolt-on ReCarb plants to existing cement and lime operators (which the company says can produce 80% more cement from the same limestone while reducing emissions by ~70%), and Verified Carbon Credits generated from the CO2 mineralization process and listed on third-party-verified registries.

The company operates its first commercial ReCarb plant in Redding, California (opened April 2024). In December 2025 ReAct Cement became the first low-carbon cement to meet all six ASTM C1157 performance categories simultaneously (General Use, High Early Strength, High Sulfate Resistance, Low Heat of Hydration, Moderate Heat, High Resistance to Deterioration), validated by Construction Testing Services; the Redding facility holds ISO 9001:2015 certification and Fortera operates an AASHTO-accredited Cement and Concrete Physical Testing Laboratory. ReAct Blend is compatible with ASTM C150, C595 and C1797 specifications, positioning it as a drop-in SCM rather than a niche chemistry.

Fortera serves cement and lime producers as plant-and-procurement partners, construction contractors deploying ready-mix concrete pours (documented projects at UC Berkeley, Simpson University, DPR Construction, South Bay Construction, Webcor Concrete, LCM Concrete, SK Construction / Wards Concrete, Freddy's Concrete), and corporate procurement offtakers seeking low-carbon inputs—most notably Microsoft, which secured procurement rights for ReAct cement and associated environmental attribute certificates for datacenter construction as part of a 2025 strategic investment. The company is backed by Temasek, Khosla Ventures, Microsoft Climate Innovation Fund, Presidio Ventures (Sumitomo affiliate), Saint-Gobain NOVA, Alumni Ventures and Wollemi, with disclosed funding of at least $159.6M across equity, US Department of Energy grants and corporate rounds. Its go-to-market pairs direct California concrete pour delivery with global plant deployment partnerships (Graymont for international rollout, Sumitomo network for APAC, Microsoft as anchor offtake and capital partner).

Core offering

Fortera manufactures and sells low-carbon cement products (ReAct Cement and ReAct Blend) produced via its proprietary ReCarb process, which captures CO2 from cement and lime plant kiln exhaust and mineralizes it into reactive calcium carbonate cement. The company also offers turnkey ReCarb Plant bolt-on decarbonization solutions to existing cement/lime producers, plus verified carbon credits generated from the ReCarb process.

Product overview

Fortera offers a unified product portfolio centered on its proprietary ReAct technology for low-carbon cement production. The core offerings consist of ReAct Cement (a 100% Portland Cement replacement) and ReAct Blend (a supplementary cementitious material), both produced through the ReCarb Plant technology that bolt-on to existing cement facilities. The ReCarb process captures CO2 from kiln exhaust and converts it into reactive calcium carbonate (ReAct), reducing emissions by up to 70% compared to ordinary Portland cement. Supporting offerings include verified carbon credits. The company operates its first commercial plant in Redding, CA and has partnerships with Microsoft, Graymont, and Sumitomo Corporation for global deployment.

Products and services

• ReAct Cement A 100% replacement for Ordinary Portland Cement binder based on the transformation of vaterite to calcite. The first cement to meet all six ASTM C1157 performance categories simultaneously, offering high CO2 avoidance, superior whiteness, and dimensional stability. Intended for concrete producers, ready-mix suppliers, and construction firms seeking low-carbon cement binder.
• ReAct Blend A performance-enhancing supplementary cementitious material (SCM) blended into ASTM C150, C595, C1157, or C1797 cements or mixed into concrete during batching. Provides low clinker blend, improved particle packing, faster strength gain, and strong reactivity with alumina.
• ReCarb Plant A turnkey, bolt-on decarbonization solution designed to integrate with existing cement and lime plant infrastructure. Captures CO2 from kiln exhaust and mineralizes it into ReAct cementitious material, enabling plants to produce 80% more cement from the same amount of limestone while cutting emissions by 70%.
• Verified Carbon Credits Carbon credits generated from the ReCarb process that help fund installation and operation of ReCarb plants. Credits are listed under trusted, leading registries and verified through third-party organizations. ReAct is composed of 44% CO2 that otherwise would have been emitted.

Direct peers

• Sublime Systems: Sublime Systems is a U.S.-based startup developing an electrochemical process to produce zero-carbon cement without fossil-fuel kilns. Like Fortera, it is targeting direct displacement of Portland cement with a low-carbon binder for the concrete value chain.
• Brimstone: Brimstone produces calcium silicate cement from carbon-free raw materials using a different process than Portland cement. It is a head-to-head competitor pursuing the same 100% replacement opportunity for Portland cement that Fortera's ReAct targets.
• CarbonCure Technologies: CarbonCure injects captured CO2 into ready-mix concrete. It is highly comparable to Fortera in addressing cement/concrete decarbonization and has acquired Solidia Technologies, providing overlapping capability across low-carbon binders and CO2 utilization in concrete.
• Solidia Technologies: Solidia developed a low-carbon cementitious binder using a CO2-cured process. It directly competes with Fortera's ReAct on supplying alternative binders and CO2-utilizing cement solutions to the concrete industry.

Emerging players

• Terra CO2: Terra CO2 is an early-stage company producing supplementary cementitious materials from silicate rock feedstock. It overlaps with Fortera's ReAct Blend SCM strategy and targets the same low-carbon cement value chain.
• Carbon Upcycling Technologies: Carbon Upcycling Technologies converts CO2 into supplementary cementitious materials and other construction inputs. It is an emerging player with partial overlap to Fortera's ReAct Blend SCM offering and CO2 utilization platform.

Broad incumbents

• Holcim: Holcim is one of the world's largest cement producers with a global decarbonization roadmap including ECOPact and reduced-CO2 product lines. It is a critical incumbent — both a potential ReCarb licensee and a competitor with internal R&D programs. Keith Krugh (Fortera CMO) is a former Holcim executive.
• Heidelberg Materials: Heidelberg Materials is a global cement incumbent with major decarbonization commitments, including CCUS pilots and lower-CO2 cement products. Like Holcim, it is both a potential partner and a competitor for ReCarb licensing opportunities.
• CEMEX: CEMEX is a major global cement producer with a Vertua low-carbon product family and active investments in CCUS. It is comparable to Fortera as a large incumbent it must both partner with and compete against in low-carbon cement markets.

Others

• Carbon Clean: Carbon Clean provides industrial point-source CO2 capture technology to cement, steel, and other heavy industries. It is thematically adjacent to Fortera's ReCarb, which captures kiln CO2 and mineralizes it on-site, but competes in industrial CCUS rather than binder manufacturing.
