cement is the world’s leading construction material — but did you know producing it is one of the major sources of greenhouse gas emissions accounting for about 8 percent of all such releases? this means that if cement production were a country, it would be the world’s third-largest emitter. aiming to solve this problem, a team of researches at MIT has come up with a new way of manufacturing emission-free cement that could eliminate the total emissions while also making other useful products in the process.
‘about 1 kilogram of carbon dioxide is released for every kilogram of cement made today,’ comments yet-ming chiang the kyocera professor of materials science and engineering at MIT. ‘that adds up to 3 to 4 gigatons (billions of tons) of cement, and of carbon dioxide emissions, produced annually today, and that amount is projected to grow.
