Why Magnesium Carbonates?: Why Magnesium Carbonates?
Because of the low molecular weight of magnesium, magnesium oxide which hydrates to magnesium hydroxide and then carbonates, is ideal for scrubbing CO2 out of the air and sequestering the gas into the built environment: More CO2 is captured than in calcium systems as the calculations below show. At 2.09% of the crust magnesium is the 8th most abundant element Magnesium minerals are potential low cost. New kiln technology from TecEco will enable easy low cost simple non fossil fuel calcination with CO2 capture of magnesium carbonate. Why Magnesium Carbonates?: Why Magnesium Carbonates? Reactive, low lattice energy forms of magnesium oxide are most suitable as they are Easier to get into solution Efficiently absorb CO2 A high proportion of CO2 and water means that a little MgO goes a long way. In terms of sequestration or binder produced for starting material in cement, eco-cements are much more efficient. Capture of CO2 during manufacture and use for sequestration directly in the built
