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 ...

A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate, one ...

Together with a team they developed a method to combine old concrete with carbon dioxide, taken from the air or industrial exhaust, to create a new, durable material called calcium carbonate concrete.

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 ...

Keeping the carbon ... with carbonate-based ones. “These alone could store 1 billion tonnes of CO 2,” she says. “The sheer magnitude of carbon storage is pretty impressive, especially when you put it ...

That’s the calcium carbonate, what the carbon turns into ... Natural rocks capture carbon dioxide too. Steel slag does it many times faster. And it’s really cheap. Actually, Sean McCauley ...

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 team of researchers from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, has developed an innovative green pesticide formulation that could make pest control safer and ...

Carbon dioxide that is present in the atmosphere dissolves into the ocean. This lowers the pH, making it more acidic.' Ocean acidification can affect any animal that has a calcium carbonate ...
