About 30 billion metric tons of carbon dioxide generated each year by power plants, vehicle engines and industrial sources that use fossil fuels. Angela Belcher, a MIT engineer perform a new genetically engineering ordinary baker’s yeast, more beneficial in reducing the supply of carbon dioxide by turning it into solid carbonate that can be used for building construction.
In the laboratory, the scientists have managed to convert one pound of carbon dioxide into two pounds of carbonate. Carbon dioxide combines with the mineral ions to form solid carbonates. Belcher and her team drew inspiration from the shells of marine animals that build their own rock-solid carbon dioxide and mineral ions dissolved in seawater.
Using step to capture carbon dioxide in water and then the dissolved carbon dioxide is combined with mineral ions to form solid carbonates. Next, they hope to develop the process so it could be applied in power plants or industrial plants.
