Cambridge Scientists say they can make zero-emission cement

Cement binds concrete together but the whitish powder is highly carbon-intensive to produce, with the sector generating more than triple the emissions of global air travel. 


Researchers from Britain's University of Cambridge have shown that cement can be recycled without the same steep cost to the environment as making it from scratch. This novel method will allow the production of high amounts of concrete while drastically lowering carbon emissions. This potentially game-changing approach uses electric arc furnaces (EAF) to recycle cement.

The team at Cambridge believes it has a solution, pioneering a method that tweaks an existing process for steel manufacturing to produce recycled cement without the associated CO2 pollution.
