Solar thermal process produces cement with no carbon dioxide emissions | physorg.com
While the largest contributor to anthropogenic greenhouse gas emissions is the power industry, the second largest is the more often overlooked cement industry, which accounts for 5-6% of all anthropogenic CO2emissions. For every 10 kg of cement produced, the cement industry releases a full 9 kg of CO2. Since the world consumes about 3 trillion kg of cement annually, this sector has one of the highest potentials for CO2 emission reductions. But while processes are being explored to sequester the CO2 from cement production, so far no process can completely eliminate it.
