Lower carbon dioxide emissions on the horizon for cement
(PHYSorg.com Chemistry)

Concrete is the most widely used building material in the world. As a key component of concrete, cement-and more specifically its production process-is a significant contributor to climate change. Every year, over 4 billion tonnes of cement are produced, and this activity is responsible for around 8 percent of global CO2 emissions. Surprisingly, around 60 percent of the CO2 emissions associated with this production aren`t released from the combustion of fossil fuels, but from the chemical reaction in the process. With this challenging problem in mind, the EU-funded LEILAC project developed a breakthrough technology with the potential to dramatically reduce the emissions of Europe`s cement and lime industries.
