A new cement-making process could sharply reduce pollution from one of the world's most carbon-intensive industries. In a study published May 13 in ACS Energy Letters, researchers described an ...

Cement is necessary for making concrete, which is foundational in constructing buildings and infrastructure around the globe because it is relatively low-cost, strong and durable. But making cement ...

You might use the words cement and concrete interchangeably, but they're actually two different materials, and one is used to make the other.

One of the biggest problems in dealing with carbon dioxide emissions is the making of the key component of cement: lime (calcium oxide). Now, a small company with the cute name Sublime Systems appears ...

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. The UCLA team ...

Researchers on Wednesday said they were a step closer to solving one of the trickiest problems in tackling climate change—how to keep making cement despite its enormous carbon footprint. In a world ...

Near-zero cement takes a huge bite out of emissions Cement has been a vital building block (pun intended) in constructing civilization. However, its manufacturing process has also made it a wrecking ...

A new cement-making process could shift production from being a carbon source to a carbon sink, creating a carbon-negative version of the building material, researchers report March 18 in Advanced ...

In a move that could accelerate the transition to "green concrete," two of the world's major cement producers are investing $75 million in Sublime Systems, a low-carbon cement startup. According to ...

A photobioreactor, which looks like a large vat of blue liquid with pink light shining, at Prometheus Materials. Stimulated by light, microbes in this bioreactor multiply and react carbon dioxide with ...

The billions of tons of cement made each year have an enormous carbon footprint: 8% of global emissions, or four times more than the airline industry. That’s both because of the energy used to make ...
