Electrochemistry can cut cement’s carbon footprint to virtually zero
Cement’s carbon emissions are a big problem for the industry but renewable energy could see the process go green
Four billion tonnes of cement are made every year – humanity doesn’t produce more of anything else – and its production accounts for around 8% of the world’s carbon emissions. But cement’s polluting ways could be over if its production could be electrified. That’s according to researchers in the US who have developed an electrochemical process that can produce cement that has almost no carbon footprint.
