Carbon dioxide (CO2)

What is carbon dioxide?

Carbon dioxide (CO₂) is a colorless, slightly acidic, non-flammable, and inert gas under normal conditions. It occurs naturally in the atmosphere and is essential in many biological and industrial processes. Depending on its use, it can be supplied in gaseous, liquid, or solid (dry ice) form.

Its versatility and safety make it one of the most sought-after technical gases in sectors such as food, medicine, agriculture, security, and winemaking.

Food, medical and industrial applications of CO2

1. Food industry

  • Carbonation of beverages: Used to create bubbles in soft drinks, beers, sparkling wines, ciders, and vermouths.
  • Modified atmosphere packaging (MAP): Extends the shelf life of packaged foods by maintaining their freshness and preventing the growth of microorganisms.
  • Preservation and refrigeration: Dry ice (solid CO₂) is ideal for keeping products frozen during transport, without leaving any residue.

2. Health and medicine

  • Insufflation in endoscopies and laparoscopies: CO₂ allows for the expansion of internal cavities to facilitate visualization and surgical access.
  • Cell culture and biological transport: Provides a suitable environment for the preservation and analysis of medical samples.

3. Firefighting

  • Carbon dioxide is effective in extinguishing Class A, B, and C fires in unoccupied areas.
  • It leaves no residue, is non-corrosive, and is not electrically conductive, making it ideal for protecting electronic equipment and technical areas.

4. Agriculture and fertilization

  • Used in fertigation and carbon fertilization, CO₂ improves crop productivity, accelerates plant growth, and reduces fungal activity.
  • It allows for increased fruit quality and optimized root development.

5. Enology and viticulture

  • In its gaseous phase, it is used to inertize barrels and protect the wine from contact with oxygen.
  • In the form of dry ice, it is used for cooling and transporting grapes, preserving their quality from harvest to the winery.
