A new technique can produce cement using waste from demolished buildings, which researchers say could save billions of tonnes of carbon by 2050. “We have definitely proved that cement can be recycled ...

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 ...

Concrete is the foundation of communities across the globe. More than 4 billion tons of cement that goes into concrete is produced a year. Locally, the Cal Portland Redding Cement Plant in Mountain ...

Concrete makers around the world are racing to reduce emissions from the ubiquitous but hard-to-decarbonize industry. This week, that global effort took an important step forward at a modest facility ...

There is no shortage of low-carbon and carbon-capturing concrete alternatives in the works, but MIT spinout Sublime Systems is particularly interesting, since it takes a novel electrochemical approach ...

Chemists at Stanford University have developed a low-cost way to remove carbon dioxide (CO) from the atmosphere using an unlikely source: rocks. The process involves heating common minerals, so they ...

It's a major contributor to climate change — the way buildings and roads are made with concrete. It's also a problem that's growing as more of the world develops. So the race has been on to find ...
