A ‘green’ use for air-captured CO2: Growing beneficial algae
As the world looks for ways to reduce greenhouse gases, researchers are exploring not only how to pull carbon dioxide from the air, but also what to do with it once it is captured.
A team of Arizona State University researchers is testing one possible answer: using CO2 from the air to help grow cyanobacteria and algae, tiny photosynthetic organisms that can be used to make fuels, chemicals, proteins, pigments and other useful products.
