Huge potential as over 15 billion tonnes concrete used annually Other Wastes Simplified TecEco Reactions Tec-Kiln MgCO3 MgO + CO kJ/mole Reactor Process MgO + CO 2 MgCO kJ/mole (usually more complex hydrates) Magnesium Thermodynamic Cycle Tonnes CO2 sequestered per tonne magnesium with various cycles through the TecEco Tec-Kiln process. Assuming no leakage MgO to built environment (i.e. complete cycles). Billion Tonnes Tonnes CO 2 sequestered by 1 billion tonnes of Mg in seawater Tonnes CO 2 captured during calcining (same as above) Tonnes CO 2 captured by eco-cement Total tonnes CO 2 sequestered or abated per tonne Mg in seawater (Single calcination cycle) Total tonnes CO 2 sequestered or abated (Five calcination cycles.) Total tonnes CO 2 sequestered or abated (Ten calcination cycles) CO 2 Eco-Cement Tec-Cement Sequestration Table – Mg from Seawater CO 2 directly from the air
