Tech

Biocement® grows in ambient temperatures, building with carbon to create controlled, structural cement for products or applied services.

Deploy

Precast products, field-tested shoreline defense, soil stabilization, and logistical infrastructures that actively sequester environmental carbon.

Tech

Geomimetic mineralization technology uses CO₂ from any source as a feedstock to create carbon-negative aggregate.

Deploy

Coarse and fine aggregates containing sequestered CO₂ for cast in place concrete deployed via ready-mix concrete producers.

Impact

CarbonStar rating of -494 lbs of CO₂ per cubic yard of concrete.

Tech

Carbon-negative process that produces portland cement and SCM from a carbon-free calcium silicate rock instead of limestone.

Deploy

Portland cement from the Brimstone process is physically and chemically identical to conventional portland cement.

Impact

As reflected in a third-party LCA, the Brimstone process is carbon-negative across a range of energy-use scenarios.

Tech

Ultra-low carbon concrete process technology combines a retrofit of existing concrete masonry plants using off-the-shelf equipment and new mix designs that include low-carbon raw materials and waste CO₂.

Deploy

Commercially available concrete masonry units at CarbonBuilt's flagship retrofit in Alabama, with additional retrofits underway.

Impact

70-100% carbon footprint reduction, through both avoidance and mineralization, compared to facility baseline.

Tech

Renewable electricity + CaCO3 to perform the chemical reaction with less energy and less CO₂ emitted + cheaper carbon capture.

Deploy

Cement for cast in place concrete deployed via ready-mix concrete producers.

Impact

  • More efficient production


  • No energy emissions


  • Easier carbon capture

Tech

The Fortera ReCarb™ process re-carbonates Calcium Oxide without losing its cementitious properties, resulting in a cementitious mineral that is rich in CO₂.

Deploy

  • SCM blend up to 35%


  • 100% OPC substitute

Impact

  • 70-100% Reduction in CO₂ per ton of cement


  • Commercial Plant in Redding, CA

Tech

Microalgae, sunlight, and seawater to capture and store carbon dioxide as biogenic limestone.

Deploy

Carbon-negative biogenic limestone that can help the cement industry achieve significant emissions reductions.

Impact

Elimination of all mineral emissions during traditional cement manufacturing.

Tech

Pozzotive® is a ground glass pozzolan made from post-consumer glass that decarbonizes cementitious products by replacing portland cement.

Deploy

Pozzotive® replaces up to 50% of portland cement in products including ready-mix, pre-cast, block, brick, pavers, and mortars.  It yields a stronger, more durable, high-performance concrete with significantly greater resistance to chloride and sulfate penetration.

Impact

Pozzotive® reduces CO2e from cement in concrete on a nearly a ton-for-ton basis as verified by a Climate Earth Type III EPD while diverting glass from landfills and promoting circularity.

Tech

Combines naturally occurring microalgae with other essential components to create a zero-carbon bio-cement.

Deploy

When mixed with aggregate, forms a zero-carbon bio-concrete.

Impact

Avoids the carbon-intensive operations involved in manufacturing and transporting traditional cement, sequesters embodied carbon from microalgae and biomineralization, returns virtually all production-based water to the earth.

Tech

Chemical manufacturing via increase to ambient pressure/atmospheres.

Deploy

Supplementary cementitious materials for cast in place concrete deployed via ready-mix concrete producers.

Tech

Electrochemical extraction of calcium and reactive silica from non-carbonate feedstock resulting in ASTM C1157 cement.

Deploy

Ultra-low-carbon cement for cast in place concrete deployed via ready-mix concrete producers.

Impact

Independent third-party LCA (preliminary EPD) indicating >93% reduction in CO₂.

Tech

Conversion of inexpensive, abundant, and local feedstocks from existing aggregate mines to high-performing and cost-competitive cementitious materials.

Deploy

Supplement, blend, or replace Portland cement.

Geography

Headquarters and pilot plant located in Golden, Colorado.
