Terra CO2 Raises $82 Million to Scale Low Carbon Cement Technology

Sustainable building materials startup Terra CO2 announced that it has raised $82 million in commitments in a Series B financing round, with proceeds aimed at accelerating the commercial deployment of its low carbon cement solution.

Building materials are a key source of global greenhouse gas emissions. Cement production, an ingredient in concrete, accounts for approximately 8% of global carbon dioxide emissions, with over 900 kg of CO2 emissions generated for every 1000 kg of material produced.

Founded in 2016, Terra provides high performance and environmentally solutions for the global construction materials market, including OPUS, a low carbon alternatives for cement replacement in concrete made with abundant, inexpensive, climate-friendly silicate rock feedstock. The company’s first product, OPUS SCM (Supplementary Cementitious Material) can offset the use of up to 50% of Portland cement, with every ton replaced representing a 70% reduction in CO2 emissions and a 90% NOx. The company is currently trialling its OPUS ZERO technology, aimed at replacing 100% of Portland cement.

According to Terra, by using abundant raw materials from established mines and work within existing industry infrastructure, its approach can be deployed at scale, and deliver cementitious materials that perform at least as well as traditional cement, while significantly reducing emissions.
