CarbonStrong

CarbonStrong is on a mission to decarbonize the built environment. Concrete is responsible for 8% of global CO2 emissions: more than all the world's bikes, scooters, trucks, trains and airplanes combined! CarbonStrong’s innovative technology enables production of low carbon concrete. By replacing carbon-intensive raw material (cement) with industrial byproducts from coal and steel industries. Using our propritary activation process, we upcycle flyash, steel slag, others byproducts to replace 40-50% cement. Without compromising on strength, performance of concrete. In fact, our materials make concrete more durable and economical. By generating high-quality, high-performance cement-replacement materials at scale, we help concrete producers, builders and real estate companies in meeting their net-zero goals and other climate targets.
