“MIT engineer Angela Belcher is now taking a new approach that would not only remove carbon dioxide from the environment, but also turn it into something useful: solid carbonates that could be used for building construction. By genetically engineering ordinary baker’s yeast, Belcher and two of her graduate students, Roberto Barbero and Elizabeth Wood, have created a process that can convert carbon dioxide into carbonates that could be used as building materials. Their process, which has been tested in the lab, can produce about two pounds of carbonate for every pound of carbon dioxide captured. Next, they hope to scale up the process so it could be used in a power plant or industrial factory.”
