What Terra CO2 Technologies does

Terra CO2 Technologies is a Golden, Colorado-based construction materials company that produces low-carbon supplementary cementitious materials (SCMs) as alternatives to Portland cement in concrete. The company operates a proprietary low-carbon, low-NOx thermal reactor and vitrification process that converts locally sourced mineral feedstocks, including mining tailings and industrial byproducts, into reactive SCMs. Its product portfolio centers on the OPUS family: OPUS SCM, a drop-in SCM that can offset up to 40% of Portland cement in typical mix designs while delivering a roughly 70% reduction in CO2 emissions and 90% reduction in NOx emissions versus Portland cement; and OPUS ZERO, a real zero-CO2 full Portland cement replacement based on advanced inorganic polymer chemistry that is currently in full concrete trials targeting ACI 318 compliance. A separate Mining Solutions product line applies the same OPUS binder chemistry to cemented backfill and tailings stabilization for mining operators. All products share a common deployment platform called the Advanced Processing Facility (APF), a modular manufacturing unit sited near aggregate sources.

The company generates revenue by selling bulk OPUS SCM to construction materials companies, ready-mix concrete producers, and mining operators under negotiated multi-year contracts on a per-ton basis, supplemented by a plant-build/licensee channel in which partners such as Asher Materials purchase and host dedicated Terra plants to serve regional markets. Terra is currently pre-commercial; the flagship 240,000 tons/year APF in Cleburne, Texas broke ground on December 7, 2025 with commercial production targeted for 2027. Notable commercial commitments include an exclusive agreement with Eagle Materials for three additional 240k-tpy SCM plants (signed December 2023) and a strategic investment and commercial partnership with Cemex Ventures (March 2025).

Terra has raised over $171 million in cumulative venture funding, including a $46 million Series A in 2022 led by Breakthrough Energy Ventures, plus multiple Series B closings in 2025 and 2026 totaling $147 million, and received $52.6 million in U.S. Department of Energy support in 2024. The company is led by co-founders Bill Yearsley (CEO) and DJ Lake (Founder and Chief Science Officer), with Chance Allen as COO, Dwayne Holland as SVP, and a research organization headed by Director of R&D Evelien Martens, Ph.D. The company holds 11-50 employees, has received AASHTO accreditation for its cement and concrete laboratory, and operates a domestic-only geographic footprint with a concentration of activity in Texas.

Revenue model

1. Industrial sales of cementitious materials: Sales of OPUS SCM (and OPUS ZERO) supplementary cementitious materials to construction materials companies, ready-mix concrete producers, and mining operators. Revenue is unit-based (per ton) tied to production capacity at facilities such as the planned 240,000 tons/year Cleburne, Texas plant (expected commercial production 2027). The company is currently pre-commercial with first revenue expected once plants come online.

Core offering

Terra CO2 Technologies manufactures and sells low-carbon supplementary cementitious materials (OPUS SCM) and a zero-CO2 alternative to Portland cement (OPUS ZERO). It produces these drop-in cementitious materials from abundant, locally sourced silicate mineral feedstocks (including mining tailings and industrial byproducts) using a proprietary, patent-protected low-carbon, low-NOx thermal reactor and vitrification process deployed via its modular Advanced Processing Facility (APF) platform. The company also offers Mining Solutions that apply its OPUS binder chemistry to stabilize mine tailings, mitigate acid rock drainage, and produce cemented backfill.

Product overview

Terra CO2 is a construction materials company offering a single, integrated OPUS product family (plus a separately marketed Mining Solutions application) rather than a multi-module software platform. The portfolio centers on two related, drop-in cementitious materials that share a common low-carbon, low-NOx Advanced Processing Facility (APF) production platform: OPUS SCM, the commercially ready supplementary cementitious material that can replace up to 40% of Portland cement and deliver a 70% CO2 / 90% NOx reduction; and OPUS ZERO, the next-generation real zero-CO2 alternative cement currently in full concrete trials that targets 100% Portland cement replacement. The same OPUS chemistry is also offered as a Mining Solutions product line that converts mine tailings into binders for cemented backfill and tailings stabilization. The shared APF infrastructure is deployed at or near partner aggregate mine sites (e.g., the 240,000 tpy Cleburne, Texas facility with Asher Materials, and three 240,000 tpy plants under exclusive agreement with Eagle Materials) to localize production and integrate with existing construction supply chains.

Direct peers

• CarbonCure Technologies: CarbonCure injects captured CO2 into concrete during mixing to reduce cement content and sequester carbon. It is a direct competitor to Terra CO2 in the low-carbon concrete/cementitious materials space, targeting ready-mix producers and developers seeking embodied-carbon reductions.
• Sublime Systems: Sublime Systems produces low-carbon cement using an electrochemistry-based process that avoids traditional kiln emissions. It is a direct competitor focused on replacing Portland cement, overlapping with Terra's OPUS ZERO ambition and competing for the same low-carbon cement procurement budgets.
• Brimstone: Brimstone makes carbon-negative Portland cement from industrial byproducts (notably calcium silicate). It is a direct competitor in low-carbon and carbon-negative cement, addressing the same concrete decarbonization market as Terra's OPUS ZERO and competing for infrastructure and construction customers.
• Solidia Technologies: Solidia Technologies produces lower-CO2 concrete and cementitious binders via a CO2-cured process. It is a direct competitor to Terra CO2, addressing supplementary cementitious and reduced-carbon cement markets with comparable drop-in positioning.
• Carbon Upcycling Technologies: Carbon Upcycling produces supplementary cementitious materials by reacting captured CO2 with industrial byproducts such as fly ash and slag. It is a direct peer in the low-carbon SCM category and competes for the same cement and concrete producers seeking drop-in replacements for declining fly ash supply.
• Hoffmann Green Cement Technologies: Hoffmann Green produces low-carbon cements based on alkali-activated and clinker-free formulations sold into the European construction market. It is a direct peer in the low-carbon cement category, comparable to Terra's OPUS ZERO positioning.
• Ecocem: Ecocem is a specialist low-carbon cement and SCM producer focused on ground granulated blast-furnace slag and related products for the European ready-mix and cement industry. It is a direct peer in low-carbon cementitious materials, competing with Terra's OPUS SCM in industrial SCM applications.

Broad incumbents

• Holcim (LafargeHolcim): Holcim is one of the world's largest cement and aggregates producers and offers low-carbon products such as ECOPlanet. As a broad incumbent, it competes with Terra via its own SCM and low-carbon cement portfolio and through potential partnership/acquisition of startups in the space.
• Heidelberg Materials: Heidelberg Materials is a major global cement and aggregates producer with an active low-carbon and CCUS roadmap (e.g., evoZero). As a broad incumbent, it competes with Terra CO2 across the cement value chain and may partner with or acquire low-carbon cement technology providers.
• Cemex: Cemex is a global cement, ready-mix, and aggregates major with its own decarbonization roadmap and the Cemex Ventures CVC arm — itself an investor and partner in Terra CO2. As both an incumbent and a strategic investor in Terra, it represents a complex comparable that combines partnership and competitive dynamics in low-carbon cement.
