ALCCCACCCS™
The ASCON Limestone Carbonation Carbon Capture And Carbon Cured Cement Storage™ (ALCCCACCCS™) is a carbon dioxide capture technology, where limestone is heated up to 650 degrees Celsius, converting the limestone into calcium oxide, whereby a flue gas with greenhouse gas (GHG) emissions is passed through the calcium oxide. In essence 100% of the carbon dioxide in the flue gas has an affinity to the calcium oxide, impregnating the calcium oxide and ultimately this exothermic reaction results in the conversion of the calcium oxide to calcium carbonate which is used as a feedstock for carbon cured cement that is a permanent carbon dioxide storage for the built environment and in enhanced weathering (EW) applications. There is no energy penalty as the heat from the exothermic reaction is recirculated, utilising heat exchangers to heat up the next batch of limestone.
