In a world-first, scientists create eco-friendly cement from algae

Rupendra Brahambhatt of Interesting Engineering reports on an eco-friendly cement breakthrough.

The C3 Take
  • Cement is the third largest industrial polluter, according to the EPA.
  • A team of scientists from the University of Colorado-Boulder and the National Renewable Energy Laboratory (NREL) have partnered to create a carbon-neutral cement production method.
  • Using algae to biologically grow limestone, this team of researchers believed that they have cracked the code for reducing cement’s carbon footprint.
  • Importantly the method to create this cement is not very time consuming, with the scientists expecting that it can scaled quickly to fulfill total demand for cement in the U.S.

“Interestingly, concrete which is primarily made using portland cement, water, and gravel is considered the most consumed material across the globe next to water. Whether it is North America, Europe, or Asia, construction activities can not be imagined without concrete and especially portland cement.”
