When CO2 is the subject of discussion, outside of those in the gas trade, it is usually associated with greenhouse gases, a gas exhaled endlessly, and soft drinks. As those in the gas industry know all too well, CO2 has many dimensions associated with so many applications, which continue to grow and grow.

When related to green applications, the range of uses can begin with CO2 usage in solvent technologies; through to high pressure blast cleaning with high density ¼ inch pellets, insect control in grain storage environments and dry cleaning applications. The use of CO2 as an aerosol propellant, rather than usage of alternate substances, can be a green approach to aerosol technologies. Below is a brief review of CO2 uses which I would consider to be green.

Solvent technologies include carbon dioxide instead of hydrocarbon compounds (hexane and acetone), such as the extraction of essential oils from plant matter, herbs, seeds, and nuts. All the way around, green advantages can be noticed from such technologies, including the disposal of the solvent and potential residue and quality for the end product being produced. Decaffeination of coffee can be a popular, safe, environmentally friendly and more natural process compared to other alternate methods.
