New Low-Carbon Cement Is Stronger Than the Regular Stuff

A low-carbon cement developed by two MIT grads has officially exceeded industry standards for strength, durability, and more, clearing a major hurdle to commercialization.
Sublime Systems, a startup founded by two MIT grads, has developed a process that slashes the emissions generated during cement production.
Instead of using heat to extract lime from limestone, it uses a series of electro-chemical reactions — powered by electricity from renewables — at ambient temperatures to pull the cement ingredient from the rock.
Because the CO2 that remains is pure — that is, not diluted by other exhaust gasses — it’s easier to capture and store than the emissions from the traditional process.
