  • 4 ways green chemistry is helping make the world a better

    04.10.2016· Green chemistry has been pivotal in coming up with ways to use CO2 as a resource instead of having it become a waste product stuck in our air. For instance, chemists found that when CO2 molecules are kept in a transitive state, or what's known as transcritical CO2, the dynamic state in which CO2 is at the point of converting from a liquid to a gas, it can be used as an industrial refrigerant
