New Method for Cement Recycling Promises Major CO2 Reduction

Cambridge scientists develop electric arc furnace technique to produce low-emission cement from demolished concrete

Cement production is responsible for 7.5% of global CO2 emissions, second only to water in material usage.
The new process uses electric arc furnaces, typically used for steel recycling, to reactivate used cement.
This method could potentially eliminate emissions from cement production if powered by renewable energy.
The innovation could meet a quarter of the UK's cement demand and significantly reduce steel recycling emissions.
Commercial trials are underway, with the potential for global scalability and substantial climate impact.
