As government funding and subsidies for climate initiatives decrease in the US, it's imperative that these solutions provide cost competitive advantages that can work within existing industries and infrastructures. Terra's SCM provides a commercial deployment ready solution that is not dependent on subsidies, providing both investors and partners with the certainty they need.

With the new capital, Terra will be rapidly moving forward with its first 240,000 TPY commercial advanced-processing facility in the Dallas-Fort Worth market. The funding will also support expanding Terra's offices and industrial facilities, significantly growing the team, developing more shovel ready commercial projects, and further advancing new generations of cementitious products.

'Terra's mandate is to deliver cementitious material solutions that the market would purchase solely based on cost and performance, even if there was no carbon benefit. The fact that Terra's cementitious materials also offer significant carbon mitigation is an additional advantage for the built environment,' says Terra CEO Bill Yearsley.

'Terra's technology offers a combination of commercial readiness and cost competitiveness. Its ability to support the decarbonization of a heavy industry such as cement aligns with our commitment to support scalable, near-term solutions in hard-to-abate sectors,' says Steven Poulter, Head of Barclays Climate Ventures.
Terra's patented Supplementary Cementitious Materials (SCMs) process produces a high-performing, low-cost alternative to Portland Cement and depleted traditional resources such as fly ash. And unlike other low-carbon SCMs, Terra's OPUS products utilize inexpensive, abundant, and local feedstocks from existing aggregate mines, and work within existing industry infrastructure. This approach enables immediate deployment at scale, delivering cementitious materials that perform equal to or better than historical SCM while significantly reducing carbon emissions. Terra's second product, OPUS Zero, is currently in active concrete trials and would serve as a full Portland cement replacement.

Terra enables our partners to unlock low-carbon cement from source to deployment. As the critical component in creating concrete, the foundation of modern infrastructure, cement is responsible for 8% of the world's CO 2 emissions. The CO 2 and NO x emissions associated with cement make finding an alternative to current solutions a climate imperative.

Unique to Terra is their capability to work across a diverse range of silicate rock mineralogy, not constrained by feedstock availability. Terra's technology allows the company to create sustainable construction materials with the most abundant and accessible raw materials on earth from already approved and open mines.

Terra's first product, OPUS SCM (Supplementary Cementitious Material), is ready for commercial deployment, capable of replacing up to 50% OPC (Original Portland Cement) and addressing the industry's carbon emissions and dwindling feedstock challenges. Terra's OPUS ZERO™, a potential 100% replacement of OPC, is in full concrete trials. Both leverage Terra's 'drop-in' reactor solution, which seamlessly integrates with existing infrastructure and sets the foundation for the transition to real zero cement.
