SOMERVILLE, Mass.--(BUSINESS WIRE)--Sublime Systems, a developer of technology to produce decarbonized cement, today announced that it has closed a $40 million Series A funding round, led by ...

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 ...

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 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 ...

Concrete and steel production are major sources of CO2 emissions, but a new solution from Cambridge could recycle both at the same time. Throwing old concrete into steel-processing furnaces not only ...

July 2023 was the hottest month ever recorded. Scorching heat, droughts, a disruption of the polar jet stream, and record-high ocean surface temperatures offer just a taste of how climate change is ...
