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 ...

Cement has been a vital building block (pun intended) in constructing civilization. However, its manufacturing process has ...

Scientists are proposing a new way to make cement by replacing limestone with volcanic ...

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 ...

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 ...

Cement production is responsible for around 8% of global carbon emissions. Using microalgae to make a key ingredient could drastically cut that carbon footprint. During a trip to Thailand on his ...

The modern world is built on concrete, and cement is what makes it possible. You've probably heard these two terms used interchangeably, especially while watching DIY videos on YouTube. However, they ...

Cement production alone currently accounts for about 8 percent of global CO 2 emissions, so considerable effort is going into ...

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 ...
