About CO2

Carbon dioxide is an odourless, colourless gas which is part of the atmosphere. Carbon dioxide is produced during respiration, combustion of fossil fuels, fermentation and chemical processes. Carbon dioxide can also be cultivated from underground sources.

Under normal circumstances (1 bar, ambient temperature), carbon dioxide is a gas. However, under pressure and cooled it becomes liquid. Carbon dioxide also exists in a solid form, Dry Ice.


Because of its typical chemical and physical properties, CO2 plays an important role in many applications.

Physical properties:

  • colourless
  • inert, non-flammable
  • odourless
  • neutral taste
  • non-toxic
  • bacteriostatic
  • density relative to air 1:1.529
