Lime and its Production
The lime cycle shows the stages from quarrying the limestone through to the production of mortars and plasters for our buildings and how it slowly, through the re-absorption of Carbon Dioxide, reverts to its original chemical form (Calcium Carbonate) in the wall. ... This process is called carbonation. The 'set' or carbonation must occur ...

These algae-grown limestone have a negative carbon footprint, because algae absorb CO2 during the production process. Engineers can then add this limestone to cement production to offset a quarter of its carbon emissions. "Even if the cement plants are still emitting, we're capturing the carbon somewhere else.
