CO2 mineralization Market Outlook 2026–2038: Growth Drivers, Key Companies, Strategic Developments & Adoption Forecast — A Meticulous Next™ Foresight Brief

This Meticulous Next™ brief examines CO2 mineralization in building materials, the processes that react captured carbon dioxide with minerals or waste to form stable carbonate and store it permanently in aggregates, cement products and concrete. It tests how fast CO2-cured aggregates and concrete move from first plants into regular supply to cement makers and builders, and which participants capture value among technology developers, producers and investors.

The first signal is the carbon load of the aggregate. The process developed by Blue Planet converts carbon dioxide gas into synthetic limestone aggregate, and each tonne can mineralize up to 440 kilograms of carbon dioxide, using inputs such as recycled concrete, cement kiln dust and slag. The conclusion is that aggregate, the largest volume input in concrete, can act as a carbon store, which makes the volume available for storage very large once supply scales.

The second signal is producer commitment. In June 2022 Holcim North America invested in Blue Planet Systems of Los Gatos, California, and began a multi-year collaboration covering Holcim US and Lafarge Canada cement, aggregate and concrete operations, with the Lafarge St Constant plant in Montreal planned as a carbon campus and the aim of using carbon dioxide captured at its own cement plants to make carbon-neutral or carbon-negative sand and gravel. Knife River, Mitsubishi and Chevron had announced stakes in Blue Planet since 2020. The conclusion is that a global cement major, an aggregates producer and an energy major have placed capital behind the route, which marks the shift from pilot to commercial plans.

The third signal is the coalition. In January 2024 ten North American companies including Biomason, Brimstone, Chement, Fortera, Terra CO2, Blue Planet, CarbonBuilt, Minus Materials, Queens Carbon and Sublime Systems launched the Decarbonized Cement and Concrete Alliance, with policy work on tax credits, standards, ecolabeling and subsidies in line with a US Department of Energy strategy for low-carbon cement. A March 2026 trade headline reports Blue Planet ramping up production of mineralized CO2 aggregate. The conclusion is that developers are organising to win procurement and policy support, and the ramp headline points to output rising.

The brief treats CO2 mineralization as an accelerating category with a twelve year horizon to 2038. It identifies which routes, products and regions scale first and what each means for cement makers, aggregate producers and builders.

It is a focused 104-page decision brief for cement makers, aggregate producers, builders, technology developers and investors. It presents an indicative trajectory rather than a segmented market model. Its purpose is to identify which routes scale first, who captures value, and which indicators to track.

The carbon source is the first layer. Carbon dioxide is captured from cement plant flue gas or other industrial sources.

The mineral source is the second layer. Recycled concrete, cement kiln dust, slag or natural minerals provide the calcium or magnesium that reacts with carbon dioxide.

The reaction is the third layer. Carbon dioxide is mineralized in a reactor, in curing chambers or injected into fresh concrete, forming stable carbonate.

The product is the fourth layer. Synthetic limestone aggregate, CO2-cured precast and ready mixed concrete and supplementary materials enter standard supply chains.

The limits are the cost and supply of captured carbon dioxide, energy use, product qualification and the recognition of the storage in carbon accounting. The decade turns on whether plants run at scale with low cost carbon dioxide at cement sites.

The CO2 mineralization market, covering aggregates, concrete and other building materials that permanently store carbon dioxide as carbonate minerals, is valued at USD 0.4–0.7 billion in 2026 and is projected to reach USD 3.57–6.24 billion by 2038, at a CAGR of 20%, and excluding carbon capture equipment sold without mineralization.

The 2026 base rests on commercial CO2-cured concrete plants and the first mineralized aggregate production. From that base, growth follows carbon dioxide supply at cement sites, procurement rules and tax credits.

The forecast is sensitive to carbon dioxide cost, policy support and qualification by standards. Regionally, North America leads on developers and incentives, Europe on carbon pricing, and Asia-Pacific on potential volume.

The base case assumes plants ramp, carbon dioxide supply at cement sites grows and procurement rules recognise storage, giving the inflection in 2033. An accelerated case assumes strong incentives and fast plant build, bringing the inflection to 2031 and lifting the 2038 value to the top of the range. A delayed case assumes slow qualification and weak policy, holding growth at the bottom of the range.

Growth drivers

• Pressure on cement and concrete producers to cut embodied carbon.
• Aggregate as the largest volume input that can store carbon.
• Availability of captured carbon dioxide and waste minerals at cement sites.
• Incentives and low-carbon procurement rules.

Enablers

• Producer investment in mineralization developers.
• Carbon campus sites that combine capture and mineralization.
• Alliances that coordinate policy and standards work.
• Tax credits and federal procurement support.

Restraints and barriers

• Cost and supply of captured carbon dioxide.
• Energy use of mineralization reactors.
• Qualification of new aggregates and concrete by standards.
• Uncertain recognition of storage in carbon accounting.

Five converging forces will determine how CO2 mineralization evolves.

The brief assesses each force for direction, speed and confidence.

The key participants in CO2 mineralization include Blue Planet Systems Corporation, CarbonCure Technologies Inc., CarbonBuilt, Inc., Carbon8 Systems Limited, Solidia Technologies, Inc., Fortera Corporation, Biomason, Inc., Brimstone Energy, Inc., Sublime Systems, Inc., Terra CO2 Technologies Holdings, Inc., Minus Materials, Inc., Holcim Ltd, Lafarge Canada Inc., Heidelberg Materials AG, CEMEX S.A.B. de C.V., Knife River Corporation, Mitsubishi Corporation, Chevron Corporation, Carbfix hf., Mineral Carbonation International Pty Ltd, Chement, Queens Carbon, 44.01, CRH plc, Vulcan Materials Company, Martin Marietta Materials, Inc., Summit Materials, Inc., Sika AG, Master Builders Solutions, Compagnie de Saint-Gobain S.A., Cementos Argos S.A., Taiheiyo Cement Corporation, Anhui Conch Cement Company Limited, Buzzi S.p.A., Votorantim Cimentos S.A., JSW Cement Limited, Decarbonized Cement and Concrete Alliance, National Ready Mixed Concrete Association, Portland Cement Association, Global Cement and Concrete Association, U.S. Department of Energy, Natural Resources Canada, European Commission, XPRIZE Foundation, Breakthrough Energy, University of California Los Angeles, Imperial College London and ETH Zurich.

The brief profiles representative participants in each archetype and assesses which are positioned to lead as CO2 mineralization matures.

The competitive landscape is forming around six archetypes. Mineralization technology developers. Cement and aggregate producers. Investors, admixture firms and offtakers. Research bodies. Governments and agencies. Industry associations. Competitive intensity is moderate in 2026 because many developers compete for a few anchor producers, and it rises as plants scale.

Where value migrates.

In 2026 value sits with developers that run plants at cement sites and with producers that secure first access and a stake. By 2033 it moves toward producers and developers with low cost carbon dioxide supply and qualified products, because the advantage comes from cost per tonne stored. By 2038 it settles in integrated cement and aggregate groups with their own carbon capture and mineralization, and in developers with licensed processes. Margins hold where procurement rules reward stored carbon and narrow as capacity grows.

The signals converge on producer investment, coalition building and rising output. Holcim invested in 2022, ten developers formed an alliance in January 2024, and trade press reported a production ramp in March 2026. Each signal supports growth, and each depends on plants running at cost.

Structural limits show where progress could slow: cost and supply of captured carbon dioxide, reactor energy use, qualification by standards and uncertain carbon accounting. The brief therefore tracks four indicators: tonnes of carbon dioxide mineralized, plant commissioning, procurement rule changes and credits, and producer offtake.

Regionally, North America leads on developers and incentives, Europe on carbon pricing, and Asia-Pacific on potential volume. CO2-cured concrete, then mineralized aggregate, then supplementary materials and cement products are the expected order of development.
