After a decade in the works, researchers at University of California, Los Angeles, have successfully devised a way to produce cement with 98% less CO2 emissions than traditional methods.

Construction materials such as concrete and plastic have the potential to lock away billions of tons of carbon dioxide, according to a new study by civil engineers and earth systems scientists at the University of California, Davis and Stanford University.…

Using more sludge and less slag in their recipe, researchers were able to create a material that's stronger than even today's enhanced cements and highly resistant to corrosion by acid. It could solve a serious problem facing sewer pipes worldwide.
