Technology
Limestone is made up of calcium oxide and CO 2. When CO 2 is removed from limestone, the remaining calcium oxide acts like a sponge – absorbing CO 2 so it can return to its natural limestone state. Our technology accelerates this natural property of limestone, reducing the time it takes to absorb CO 2 from years to just 3 days.

Steel Production
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...
