Sustainability of CO2


CO2 is non-flammable, relatively inert, non-carcinogenic, non-mutagenic, shows a very low toxicity and is inexpensive. By compressing CO2 it shows solubility of liquids and penetration of gases and exhibits excellent heat and mass transfer properties. CO2 is able to penetrate into solid structures, to change material properties and to enable the transport of other substances into or out of solid structures.

The gaseous CO2 employed can be recycled after processing and can be reused in the next process cycle. Most of the CO2 employed in processes today accumulates as byproduct in processes like ammonia production so that the CO2 has not to be counted as "emitted CO2".
