Imagine Freeways Being Carbon Sinks
Other companies attempting future-friendly cement include California start-up Calera; which is sited next to power plants to clean them up by utilizing their carbon emissions to make cement. They are trying to sequester carbon into cement the way that marine organisms do; forming carbonates at normal temperatures from calcium, magnesium and CO2.
The search for new carbon-free technologies creates so much innovation. Some of these inventions move quite fast from government funded research lab to venture funded new business. Novacem is contemplating realistic commercial-scale production within five years.
Major cement makers have invested in modern kilns and reduced carbon-heavy materials to try to reduce carbon emissions, but with only very limited success. By contrast, Novacem could turn the cement industry from a big emitter to a big absorber of carbon.
Imagine freeway overpasses becoming carbon sinks! How ironic. We wouldn’t have needed carbon sinks if we hadn’t invented the internal combustion engine — creating the need for freeways.
