ZeroCAL process

Caption

The ZeroCAL approach, which can be integrated within the existing cement-production process, uses limestone feedstock to produce calcium hydroxide — which emits no carbon dioxide when burned to produce lime for cement. Byproducts of the process include hydrogen gas, which can be used as a clean-burning fuel to heat cement kilns.
