Cambridge Researchers Pioneer Low-Emission Concrete Using Recycled Cement

Innovative method leverages electric arc furnaces to drastically reduce CO2 emissions in concrete production.

New technique uses recycled cement as a substitute for lime flux in steel recycling.
Electric arc furnaces enable large-scale production of low-emission concrete.
Method could achieve zero-emission cement if powered by renewable energy.
Recycled cement production does not add significant costs to concrete or steel manufacturing.
Researchers aim to scale production to one billion tonnes annually by 2050.
