Steel slag captures carbon from the atmosphere. Companies with climate goals — and an Ohio motocross raceway — are making use ...

A University of Nebraska-Lincoln research team has identified new microscopic players in the global carbon cycle, a discovery ...

So, if we have calcium carbonate and we heat it, it breaks down to produce calcium oxide and carbon dioxide. Gethin: OK, I know you're poised with your pen and your flip chart. But, before that ...

In this process known as calcium looping, calcium oxide reacts with carbon dioxide to form calcium carbonate when heated to temperatures of around 650 degrees Celsius. The reaction is reversible ...

Sequestration: The process of capturing and storing carbon dioxide to prevent it from entering the atmosphere. Calcium Carbonate (CaCO3): A chemical compound that occurs naturally in rocks and is ...

A Nebraska research team recently published a study in Communications Earth and Environment that is one of the first to show ...

Researchers in Japan found a way to make concrete that effectively emits no carbon dioxide (CO2 ... To make concrete, limestone, or calcium carbonate, is mixed with clay and other materials ...

Materials such as concrete containing carbonate-based aggregates, bio-based plastics and biochar could sequester more than 16 billion tonnes of CO2 a year ...

Construction is imminent for a carbon-capture project aimed at reducing CO2 emissions from steel production while producing carbon-neutral calcium carbonate. At the U.S. Steel manufacturing facility ...

Ocean ecosystems play a critical role in carbon storage and oxygen ... Some plankton combine calcium and dissolved carbonates to form a calcium carbonate protective coating like the shells and ...

A new company has been reaching out to farmers with a soil amendment and an offer that sounds too good to be true, so ...

The carbon dots (LysCDs) combined with calcium carbonate (CaCO 3 ... into harmless substances like calcium ions (Ca²⁺), carbon dioxide (CO₂), and carbon dots, significantly lowering the ...
