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 ...

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 ...

This strange white paste might not look like much, but it might help solve the sand shortage, while making the cement manufacturing process capture carbon dioxide instead of emitting it. Scientists at ...

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 ...

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 ...

Concrete and steel production are major sources of CO2 emissions, but a new solution from Cambridge could recycle both at the same time. Throwing old concrete into steel-processing furnaces not only ...

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 ...

MIT researchers used laser imaging to reveal how CO2 injection creates hidden chemistry in cement, boosting strength by 13% ...
