“Scientists say they’ve found a way to recycle cement from demolished concrete buildings.“
“The BBC was present when (CEC’s) first high grade, or “Portland”, cement was produced.
They are calling it “electric cement” and described the event as a world first.
The lead researcher, Cyrille Dunant, told the BBC it could enable the production of zero-carbon cement.
“We have shown the high temperatures in the furnace reactivate the old cement and because electric arc furnaces use electricity they can be powered by renewable power, so the entire cement making process is decarbonised.,” he said.
He said it also makes steel recycling less polluting because making the chemicals currently used as slag has a high carbon cost too.”
