Terra CO2 cements $124M Series B to slash concrete's carbon footprint | TechCrunch
Briefly

Terra CO2, based in Golden, Colorado, has developed a low-carbon supplement to replace traditional Portland cement, contributing significantly to global carbon emissions. The startup recently closed a $124.5 million Series B funding round to support the production of its supplementary cementitious materials (SCM). This innovative SCM can replace up to 40% of Portland cement, emitting 70% less CO2. Terra CO2 plans to build a facility near Dallas to produce 240,000 tons of SCM annually. Key investors in this venture include notable environmental advocates and organizations committed to sustainability.
Cement contributes to about 8% of global carbon pollution due to CO2 released during its production, prompting startups to seek low-carbon alternatives.
