Environmental Engineers Use Algae To Capture Carbon Dioxide
Engineers have designed a simple, sustainable and natural carbon sequestration solution using algae. A team at Ohio University created a photo bioreactor that uses photosynthesis to grow algae, passing carbon dioxide over large membranes, placed vertically [...]

Calera and Novacem use concrete to capture CO2

Concrete seems pretty inoffensive. It just looks like mud, and appears to do nothing except sit there and harden. The fact is, though, concrete is the world’s third-largest source of man-made carbon dioxide. Its production process accounts for at least 5% of the CO2 our species pumps into the atmosphere annually. [...]

Missouri researchers aim to grow algae for biofuels in abandoned mines
Backers of algae-based biofuels tout the simplicity of their feedstock. Sunlight and water are all that’s needed to convert carbon dioxide into fuel.
Now, some scientists are testing the notion that sunlight might be optional.
Researchers at the Missouri University of Science and [...]
