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 ...

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 ...

Cement production alone currently accounts for about 8 percent of global CO 2 emissions, so considerable effort is going into lowering that number. Efficiency can be increased, and energy sources can ...

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 ...

Cement plants could become carbon-negative by combining electric kilns with direct air capture to pull CO2 from the ...

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 ...

Researchers at the University of British Columbia have developed a new cement production process powered by electricity. This method cuts carbon dioxide emissions by up to 98 percent and uses 70 ...

Our world is built of concrete. Durable and cheap, it’s the construction material of choice for buildings, bridges and tunnels. But its ubiquity means it has a huge environmental impact. Concrete is ...
