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

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

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 ...

Producing cement from silicate rocks rather than limestone could lower both energy requirements and carbon dioxide emissions, ...

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 ...

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 ...

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 ...

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 ...
