For massively reducing concrete's climate footprint

Concrete has been labeled the most destructive material on earth, due to its widespread use and the high carbon emissions from the cement-making process.
The American start-up CarbonBuilt claims to have found a way around that problem.
The company's Carbon XPRIZE-winning technology reduces concrete’s carbon footprint by 70-100%, compared to traditional concrete blocks – and they don’t cost more to make.
The blocks are already in production, and will be used by C&C Masonry in the construction of several municipal projects across the state of Alabama.

CarbonBuilt’s technology replaces most of the expensive, high-carbon Portland cement used in concrete manufacturing with a proprietary low-cost cement alternative made from widely available, low-carbon materials. These materials harden by chemically reacting with CO2, piped into the curing chamber from an onsite furnace that also generates heat needed for the process.
The furnace uses waste biomass that would have otherwise produced carbon emissions. This process not only strengthens the blocks, but also permanently stores the CO2 in solid form.
