Carbon Dioxide vs Hydrocarbon Extraction
August 2, 2017
There are multiple current methods for extraction of oil from cannabis, using different solvents or techniques to obtain specific types of oil products like butter, shatter, wax, or liquid oil. Most of these methods involve use of dangerous means to create these extracts. Butane hash oil extraction is probably the most well-known of these methods. Supercritical carbon dioxide extraction has been designed as an alternative method to obtain high quality oil extracts without risking damage to the operator or environment. When the benefits of supercritical carbon dioxide as a solvent are compared against butane, it becomes clear why CO2 supercritical extraction is quickly gaining preference and taking over the extraction market.
