CO2 extraction is eco-friendly for numerous reasons:
Just a small amount of plant material is called for to provide a good amount of oil. For instance, dust as well as slivers left over from the carving of Agarwood can be utilized for CO2 removal of Agarwood oil. These small particles would certainly be worthless for purification. Likewise, a smaller sized amount of this oil is required to create the desired cause a fragrance composition. Therefore, with carbon dioxide extraction priceless resources are saved, no harmful chemicals are made use of, and also no gas is melted that could contribute to the greenhouse effect.
