6 innovative startups that are kicking CO2 out of cement and concrete

Maria Gallucci and Jeff St. John of Canary Media report on six innovative startups that are kicking CO2 out of cement and concrete.

The C3 Take
  • Terra CO2 has found a way to create supplementary cement material–a common cement alternative–with a variety of silicate rocks.
  • Terra CO2 estimates that every metric ton of cement replaced by these materials will result in 70 percent lower CO2 emissions compared to pure Portland cement.
  • Brimstone, an Oakland-based startup, is replacing the limestone in cement with calcium-bearing silicate rocks that do not contain and carbon atoms, leading to carbon-free production process.

“CarbonBuilt spun out of UCLA’s engineering school in 2019. In May, the company began commercial production of its sustainable concrete at a partner facility in Alabama, where an on-site biomass furnace captures and supplies CO2. The company says it now plans to produce its Portland-cement-free blocks at ​’commercial volume’ in Alabama starting in 2024.”
