(Olivine)(greensand) - '1 kg greenSand certified olivine stores 1 kg of CO2'

'greenSand is the mineral Olivine (Mg, Fe) 2SiO4 in stone of sand. (faq)


'Sequestering CO2 with olivine

CO2 is sequestering by enhanced weathering with olivine. Olivine is a common mineral avaliable anywhere in earth's subsurface. It reacts simply with the CO2 (acid) from the atmosphere. The chemical reaction is Mg2SiO4 + 4CO2 + 2H2O => 2Mg2+ + 4HCO3- + SiO2. Herewith olivine takes up 1 times her own weight on CO2. The final products of the reaction are silicon dioxide, magnesium carbonate, and small amounts of iron oxide. greenSand prevents acidification of (agricultural) soil and water, making an optimal lime substitute and a sustainable soil nutrient.'
