Calera

Calera’s process for CO2 reduction involves the capture of CO2 gas from industrial emitting sources and converting the CO2 into a novel calcium carbonate cement system that’s used to make a variety of valuable products. Calera concentrates on the manufacture of building materials, particularly focusing on innovative board products from Calera’s novel cement system. Calera’s process removes CO2 from emitting sources by converting the gas into a solid form of calcium carbonate thereby permanently sequestering the CO2. The Calera process is unique with a CO2 capture and conversion technology that transforms CO2 into a profitable feedstock. Calera’s CO2 solution couples environmental sustainability with economic sustainability.

 

CO2 + Alkalinity + Calcium = Calcium Carbonates

The conversion of CO2 to calcium carbonate requires a source of alkalinity and calcium. One option is the use of industrial waste streams that contain both alkalinity and calcium, like calcium hydroxide (Ca(OH) 2). Another option is separate streams – an alkalinity source, such as caustic soda (NaOH), which can be supplied from the conventional industrial manufacturing process and a calcium source, like calcium chloride, which can be naturally occurring or found in the waste streams of existing chemical processes. Both methods result in the capture and conversion of CO2 to the special calcium carbonate cement which can be used to form board products.
