I am looking for a carbon capture technology that integrates directly into concrete production.

Several innovative technologies integrate carbon capture, utilization, and mineralization (CCUM) directly into the concrete manufacturing and production process. Instead of storing gaseous CO₂, these methods bind the carbon permanently into the concrete matrix as a solid mineral, often improving the material's structural compressive strength while reducing the required amount of carbon-intensive ordinary Portland cement.

Here are the leading technologies in this space:

• CarbonCure Technologies : This system injects captured, liquefied CO₂ directly into fresh concrete during batching in ready-mix or precast concrete plants. Once injected, the CO₂ immediately reacts with calcium ions to form calcium carbonate (CaCO₃), permanently mineralizing the carbon. This mineralization increases the concrete’s early-stage compressive strength, which allows producers to safely reduce the amount of cement used in the mix without sacrificing performance.
• Carbicrete : Carbicrete offers a cement-free process for precast concrete (such as masonry blocks). Instead of using carbon-heavy Portland cement, the technology uses steel slag (a byproduct of steelmaking) as the binder. During manufacturing, the concrete products are cured by infusing CO₂ into a curing chamber, where the gas mineralizes and binds the slag aggregate together. The resulting concrete is carbon-negative because more CO₂ is permanently trapped during curing than is emitted during production.
• Solidia Technologies : Solidia alters both the cement chemistry and the curing process. They produce a specialized, lower-lime cement at lower kiln temperatures, reducing the thermal emissions of cement manufacturing. Crucially, instead of curing the concrete with water (hydration), precast products made with Solidia cement are cured using CO₂, which reacts with the binder to give the concrete its strength while permanently consuming large volumes of carbon.
• Blue Planet Systems : Blue Planet targets the aggregate portion of concrete (the sand, gravel, and crushed stone that makes up 70–80% of a typical mix). They capture industrial CO₂ emissions and mineralize them into synthetic limestone CaCO₃. This manufactured limestone aggregate directly replaces quarried rock in concrete production, locking hundreds of kilograms of CO₂ into a stable crystalline form per ton of aggregate produced.

If you'd like to narrow this down, let me know:

• Are you looking for a solution for ready-mix concrete or precast manufacturing?
• Do you need a system that can be retrofitted into an existing plant?
• Are you aiming to reduce cement content or replace aggregate?

Yes. The technology category you’re looking for is CO₂ mineralization / carbon curing integrated into concrete production. The strongest commercially deployed example is CarbonCure Technologies.

Best fit: CarbonCure

CarbonCure injects captured CO₂ directly into fresh concrete during the normal mixing/batching process. The CO₂ reacts with calcium ions and converts into solid calcium carbonate, permanently embedding the carbon in the concrete. The system is designed as a retrofit to existing concrete plants and interfaces with plant batching software.

The important distinction is that it doesn't capture CO₂ from the cement plant itself. It is primarily a CO₂ utilization and permanent-storage technology: you supply captured CO₂, and the concrete production process mineralizes it.

CarbonCure reports approximately:

• Ready-mix: 7–11 kg CO₂ per m³
• Precast: 12–18 kg CO₂ per m³
• Cement reductions can provide an additional emissions benefit because mineralization improves cement efficiency.

It has also been demonstrated using direct-air-captured CO₂, so the upstream CO₂ source can theoretically be DAC rather than an industrial exhaust stream.

Other technologies worth evaluating

• CarbonBuilt — particularly interesting if you're producing concrete masonry units or precast products. It changes the binder formulation and uses CO₂ curing to mineralize carbon. A recent review reports potential embodied-carbon reductions above 70% for its process.
• Blue Planet Systems — instead of injecting CO₂ into fresh concrete, it converts CO₂ plus calcium-bearing waste into synthetic limestone aggregate. The resulting aggregate permanently stores CO₂ and is then incorporated into concrete. Blue Planet says its process can use relatively dilute CO₂ streams without requiring conventional purification.

Which one I'd investigate

If your objective is “add carbon capture/storage to an existing concrete plant with minimal changes to production,” CarbonCure is probably the closest match.

If your objective is “capture CO₂ at/near a cement plant and directly turn it into a concrete ingredient,” I'd look more closely at Blue Planet and CarbonBuilt, as well as integrated cement-plant CCU configurations. There was already a demonstration of capturing CO₂ from cement production and subsequently using it in concrete in an integrated CCU system.

If you tell me what type of concrete operation you have (ready-mix, precast, blocks, cement plant, etc.) and roughly how many cubic yards/tonnes you produce, I can narrow this down to the 3–5 most relevant technologies, including estimated CO₂ sequestration, equipment requirements, CAPEX/OPEX, and commercial maturity.

Integrating carbon capture directly into concrete production relies on carbon mineralization —a process where captured CO₂ is injected into fresh concrete or curing chambers, chemically turning into solid calcium carbonate (CaCO₃). This locks the carbon away permanently while improving the material's compressive strength.

The leading commercial technologies and systems that achieve this direct integration include:

• CarbonCure Technologies uses a retrofitted hardware system that injects precision doses of captured, liquefied CO₂ into fresh ready-mix or precast concrete during standard batching. The CO₂ mineralizes instantly, boosts strength, and allows producers to reduce their overall cement content (lowering the carbon footprint further).
• CarbiCrete replaces traditional cement entirely with industrial steel-making by-products (steel slag). During the manufacturing process, concrete blocks are cured in a chamber injected with CO₂, which binds with the slag to yield a carbon-negative structural block.
• CarbonBuilt utilizes a proprietary technology that introduces CO₂ during the curing phase of concrete manufacturing. It alters the mix design to use alternative, calcium-rich industrial waste binders, significantly cutting overall emissions.
• Solidia Technologies provides a low-lime cement alternative paired with a custom curing process. Instead of traditional water curing, concrete products are cured using CO₂, which reacts with the specialized binder to rapidly form solid structural carbonates.
• Carbonaide offers automated CO₂ curing systems designed to integrate directly into precast concrete element and block manufacturing lines to permanently mineralize waste gases into the concrete matrix.

Are you looking to integrate this technology into a ready-mix operation , a precast/block manufacturing plant , or are you exploring upstream cement production ? Let me know so I can point you toward the right setup.

Yes. The technology category you’re looking for is CO₂ mineralization integrated into concrete production. The strongest commercially deployed example I found is CarbonCure Technologies.

1. CarbonCure — closest match

CarbonCure Technologies injects captured CO₂ directly into fresh concrete during the normal mixing/batching process. The CO₂ reacts with calcium ions in the cement and forms solid calcium carbonate, permanently mineralizing the carbon inside the concrete.

The interesting part is that this isn't a separate carbon-capture plant attached to concrete production. The concrete itself becomes the carbon-utilization/sequestration step.

Process:

Captured CO₂ → onsite storage → controlled injection during batching → mineralization → CaCO₃ permanently embedded in concrete

CarbonCure says its systems can be retrofitted into existing concrete plants, with the injection equipment connected to the plant's batching software. It offers versions for ready-mix, precast, masonry and reclaimed-water applications.

For ready-mix concrete, the company currently reports roughly 7–11 kg of CO₂ saved per m³ of concrete, depending on the application and mix design.

It is also relatively mature: CarbonCure reports hundreds of systems operating globally and more than 10 million truckloads produced with its technology.

2. Blue Planet — potentially more interesting for carbon-negative concrete

Blue Planet Systems takes a somewhat different approach. Instead of injecting CO₂ into the fresh concrete, it uses CO₂ plus calcium-containing waste materials to manufacture synthetic limestone aggregate containing permanently sequestered CO₂. That aggregate is then used as a concrete ingredient.

Blue Planet reports that its synthetic limestone contains approximately 440 kg of CO₂ per tonne of aggregate.

This could be especially interesting if your goal is carbon-negative concrete, rather than simply reducing the embodied carbon of conventional concrete.

3. CarbonBuilt — another related approach

CarbonBuilt focuses on concrete masonry products and replaces a substantial portion of cement with its proprietary binder. It reports the potential for up to 70% lower carbon footprint for its concrete products.

However, it's less directly aligned with your description of captured CO₂ being integrated into the concrete production process than CarbonCure or Blue Planet.

My take

If you're looking for a technology to integrate into an existing concrete plant, I'd investigate CarbonCure first. It is essentially a drop-in CO₂-utilization system rather than a fundamentally new concrete manufacturing process. The company says installation can be completed in hours and integrated with existing batching systems.

If you're looking to design a new carbon-negative concrete production process, I'd investigate Blue Planet alongside CarbonCure because its aggregate approach potentially stores much more CO₂ per unit of material.

One important distinction: these technologies are generally carbon utilization/mineralization, not the capture technology itself. You still need a source of captured CO₂—such as a cement kiln, industrial emitter, biogenic source, or potentially direct-air-capture system. Blue Planet explicitly says its process can use CO₂ from multiple sources, including cement plants and DAC.

If you tell me whether you're looking at this for a cement/concrete plant, a startup/business opportunity, an investment, or a research project, I can dig into the technology readiness, CAPEX, CO₂ captured per ton of concrete, economics, patents, and companies currently commercializing it.

Several innovative technologies integrate carbon capture and utilization (CCU) directly into concrete production, primarily relying on carbon mineralization —a process where injected carbon dioxide (CO₂) chemically converts into a solid calcium carbonate mineral inside the mix.

Leading technologies and companies offering direct integration into concrete manufacturing include:

• CarbonCure Technologies : An industry leader that retrofits easily into existing ready-mix and precast concrete plants . It injects a precise dose of liquefied CO₂ (sourced from industrial emitters or direct air capture) into the fresh concrete mixture during batching . The CO₂ mineralizes into nano-sized calcium carbonate, which improves compressive strength and allows producers to reduce their cement content by roughly 5% without losing performance.
• CarbiCrete : Focuses on precast concrete production (like masonry blocks) with a process that completely eliminates cement from the mix . Instead of Portland cement, it uses industrial steel slag as a binder . The concrete elements are then placed in a curing chamber where captured CO₂ is introduced, mineralizing and hardening the product while achieving carbon-negative results.
• Carbonaide : A Finland-based technology that provides a CO₂ curing system designed to integrate directly into precast concrete manufacturing lines . Their automated system binds CO₂ into stone-based building products during the hardening phase, effectively turning precast elements into permanent carbon sinks to produce carbon-negative materials.
• Solidia Technologies : Offers a technology that replaces traditional Portland cement with a low-lime calcium silicate formulation for precast applications . Instead of curing with water (hydration), the concrete is cured using CO₂ gas, which reacts with the binder to form hard calcium carbonates, significantly reducing the carbon footprint of the production cycle.
• Fortera : Uses a proprietary re-carburization process that captures CO₂ emissions directly at cement manufacturing facilities . It converts limestone into a reactive supplementary cementitious material containing embedded CO₂, which can then be blended seamlessly into standard concrete production mixes.

Are you looking to integrate this technology into a ready-mix plant , a precast/masonry manufacturing facility , or are you exploring upstream cement kiln capture ? Knowing this helps narrow down the ideal fit.

Yes. If by “integrates directly into concrete production” you mean captured CO₂ is fed into the concrete plant and permanently mineralized as part of the concrete-making process, the leading commercial example is CarbonCure Technologies.

CarbonCure — probably the closest match

CarbonCure installs equipment at an existing concrete plant. Captured CO₂ is metered into fresh concrete during batching, where it reacts with calcium from the cement and forms solid calcium carbonate. The mineral becomes embedded in the concrete rather than remaining as gaseous CO₂.

The attractive part is that the technology is not a separate carbon-capture facility attached downstream of the concrete plant. It's effectively a retrofit to the batching process:

Captured CO₂ → storage tank → dosing/injection system → fresh concrete → mineralized CaCO₃

CarbonCure says its equipment connects to the plant's batching software and can be retrofitted without fundamentally changing the production workflow.

It also has substantial commercial deployment: the company reported 10 million truckloads of concrete produced using its technology by November 2025, across hundreds of plants in more than two dozen countries.

Other technologies worth evaluating

CarbonCure Technologies is therefore the one I'd investigate first if your requirement is “capture/utilize CO₂ as an integrated step in conventional concrete production.” A recent 2026 review also distinguishes direct injection into fresh concrete from CO₂-curing and mineralized-aggregate approaches.

Blue Planet Systems is particularly interesting if you're looking for much larger permanent CO₂ storage per cubic yard rather than simply reducing cement consumption. Blue Planet says its mineralized aggregate can permanently store substantial quantities of CO₂ and substitute for conventional aggregate.

If you're evaluating this for an actual plant/project, I can also compare the leading technologies on CO₂ captured per ton of concrete, equipment/capex, operating cost, cement reduction, required CO₂ purity, retrofit complexity, and commercial readiness.

Integrating carbon capture directly into concrete production typically relies on carbon mineralization —a process where carbon dioxide (CO₂) is injected into the mix or curing environment and chemically converted into solid calcium carbonate (CaCO₃). This locks the carbon away permanently and often improves the structural strength of the concrete, allowing producers to reduce the amount of carbon-heavy cement used.

Several commercial technologies and companies specialize in this direct integration:

• CarbonCure Technologies : This system retrofits directly into ready-mix and precast concrete plants. During batching, precision-measured, captured CO₂ is injected into the fresh concrete mixture. The CO₂ instantly mineralizes into nano-calcium carbonate, which increases compressive strength and enables a reduction in cement content without sacrificing performance.
• CarbiCrete : Focused heavily on precast manufacturing, CarbiCrete replaces traditional cement entirely with steel slag (an industrial byproduct). The concrete elements are then placed in a curing chamber where CO₂ is injected, binding with the slag to create a cement-free, carbon-negative building block.
• CarbonBuilt : This technology enables the manufacturing of concrete masonry units (CMUs) using alternative, low-carbon binders instead of traditional Portland cement. Their system introduces CO₂ into the curing chamber, where it is permanently mineralized, significantly lowering overall production emissions.
• Fortera : Fortera utilizes a recarbonation process that captures CO₂ directly at cement and industrial plants and transforms it into a supplementary cementitious material (SCM) or reactive CaCO₃ product that can blend seamlessly into standard manufacturing lines.

If you'd like to narrow this down, let me know:

• Are you looking at ready-mix concrete (for trucks/job sites) or precast manufacturing (blocks/panels)?
• Are you aiming to retrofit an existing plant or design a new production process?

Yes. If by “integrates directly into concrete production” you mean captured CO₂ is fed into the concrete plant and permanently mineralized as part of making the concrete, the leading commercial example is CarbonCure.

Best fit: CarbonCure

CarbonCure Technologies injects a precisely measured amount of captured CO₂ into fresh concrete during mixing. The CO₂ reacts with calcium ions in the cement and forms solid calcium carbonate, effectively locking the carbon into the concrete.

The important part is that it is not a separate carbon-storage facility. CarbonCure's equipment is retrofitted into an existing concrete plant, with a valve system connected to an onsite CO₂ supply and controls integrated with the plant's batching software.

CarbonCure reports roughly 7–11 kg of CO₂ reduction per m³ of ready-mix concrete, with the reduction coming from both mineralized CO₂ and the ability to reduce cement content while maintaining performance.

Other technologies worth investigating

Blue Planet is particularly interesting if you're looking for a more substantial carbon-storage pathway. Its process combines CO₂ with calcium-containing waste materials to produce synthetic limestone aggregate; the company says its aggregate permanently mineralizes about 440 kg of CO₂ per tonne of aggregate.

The key distinction is that CarbonCure modifies conventional concrete production, whereas Blue Planet essentially makes a carbon-sequestering aggregate that becomes part of the concrete.

If you're evaluating this for an actual plant

I'd look at five things before selecting a technology:

1. CO₂ source — flue gas, purified industrial CO₂, biogenic CO₂, or DAC.
2. CO₂ consumption per cubic yard/m³ and the resulting net CO₂ reduction.
3. Whether existing batching equipment can be retrofitted without disrupting production.
4. Cement reduction actually demonstrated in your mix designs, rather than theoretical savings.
5. Concrete-code/ASTM acceptance, EPD implications, and carbon-credit treatment in your market.

If you tell me whether you're looking at ready-mix, precast, concrete block/pavers, or a cement plant, I can narrow this down to the 3–5 technologies that are most appropriate and compare CAPEX, CO₂ captured per ton of concrete, required CO₂ purity, scalability, and commercial availability.

Yes. The technology category you’re looking for is CO₂ mineralization / carbon utilization integrated into concrete production. The strongest commercially deployed example I found is CarbonCure.

Best fit: CarbonCure

CarbonCure Technologies injects captured CO₂ directly into fresh concrete during the normal mixing/batching process. The CO₂ reacts with calcium from the cement and forms solid calcium carbonate, permanently mineralizing the carbon inside the concrete.

The important part is that you don't need to redesign the entire concrete plant. CarbonCure describes its system as a retrofit: a CO₂ supply connects to a dosing/valve system, while a control box integrates with the plant's batching software.

For ready-mix concrete, CarbonCure reports approximately 7–11 kg of CO₂ reduction per m³ of concrete, partly because mineralization can allow the producer to reduce cement content.

Other technologies worth evaluating

Blue Planet Systems takes a somewhat different approach: it mineralizes CO₂ into synthetic limestone aggregate, using calcium sources such as demolished concrete, cement kiln dust, steel slag and fly ash.

CarbonBuilt, meanwhile, developed a process in which CO₂ is embedded during curing while substantially reducing cement use.

One important distinction

If by “carbon capture technology” you mean capturing CO₂ from the cement plant's own flue gas and immediately putting that captured CO₂ into concrete, that's a more specific—and potentially more interesting—system than simply purchasing captured CO₂.

The architecture would look like:

Cement/concrete plant → CO₂ capture → purification/compression → concrete batching → CO₂ mineralization → lower-carbon concrete

That can potentially create a closed-loop carbon-utilization system at the concrete/cement facility, rather than relying on externally supplied CO₂.

If that's what you're looking for, I can identify the companies currently offering this integrated capture → concrete system, their technology readiness, approximate costs, CO₂ uptake per tonne of concrete, and which ones are actually commercially deployable in 2026.

Integrating carbon capture directly into concrete production typically relies on carbon mineralization —a process where captured CO₂ is injected into fresh concrete or used during curing, reacting chemically to turn into solid calcium carbonate (CaCO₃). This permanently sequesters the carbon and improves compressive strength, which lets producers reduce the amount of carbon-intensive cement needed.

The leading technologies and companies that integrate carbon utilization directly into the concrete manufacturing workflow include:

• CarbonCure Technologies : This system retrofits directly into ready-mix and precast concrete plants. During the batching process, a controlled amount of captured CO₂ is injected into the fresh concrete mix (or into reclaimed wash water). The CO₂ instantly mineralizes into nano-sized calcium carbonate, increasing compressive strength and allowing producers to dial back their cement content without losing performance.
• CarbiCrete : Rather than just supplementing traditional mixes, this technology replaces Portland cement entirely. It uses steel slag (a byproduct of the steel-making industry) as a binder instead of cement. Concrete elements are placed in a curing chamber where CO₂ is injected, binding the slag granules together to create carbon-negative precast concrete.
• CarbonBuilt : This technology manufactures concrete masonry units (CMUs) by replacing traditional cement with an alternative binder created from industrial byproducts. During the curing phase in a standard curing kiln, CO₂ is injected and permanently mineralized into the concrete units, reducing overall emissions by a substantial margin.
• Solidia Technologies : Solidia uses a patented low-lime cement formulation and alters the curing process. Instead of water-based curing alone, their precast concrete products are cured with CO₂, which reacts with the concrete to form a hard, durable matrix while trapping the gas permanently as a solid mineral.

Are you looking to integrate this technology into a ready-mix facility, a precast plant , or are you exploring cement-free alternatives like steel slag? I can provide more specific data on equipment footprints or curing requirements based on your setup.
