WCI #6: Cement as a carbon sponge

From SciAm:

"Traditional cement production creates at least five percent of global carbon dioxide emissions, but new materials could create carbon-neutral cement. Start-up Novacem, supported by Imperial College London, uses magnesium oxide to make cement that naturally absorbs CO2 as it hardens. California-based Calera uses seawater to sequester carbon emissions from a nearby power plant in cement."
