Oxygen is a colorless, odorless reactive gas that sustains life in the air. It makes up only 21% of the Earth's atmosphere and is the most abundant element in the Earth's crust, mainly in the form of oxides, silicates and carbonates.
In addition to being used as a breathing gas for healthcare applications, oxygen has strong oxidizing properties that can benefit many industries by increasing yield, optimizing performance, reducing costs and reducing carbon footprint compared to other fuels. Oxygen-enriched or replacement air also increases the efficiency of chemical and biological processes.

Applications that use oxygen include combustion, oxidation, fermentation, wastewater treatment, and aquaculture. Oxygen can also be used in metal cutting, welding, cleaning, hardening, cleaning and melting applications when combined with flammable gases or argon (Ar) and carbon dioxide (CO2). In the food industry, oxygen is used to maintain the fresh, natural color of red meat.
