Terra CO2 is the scalable low carbon alternative for cement production. Responsible for 8% of the world's CO2 emissions, cement is used in producing concrete, the world's second-most used material after water. Their unique technology allows Terra to create cementitious materials from a wide variety of feedstocks or waste products, dramatically reducing the greenhouse emissions caused by cement production. Terra's proprietary Opus suite of cementitious materials is a proven supplement and alternative to Portland cement. Validated by third parties, Terra's materials perform equal to or better than traditional cementitious products.
