CO2 extraction, also known as supercritical CO2 extraction, is a method of extraction popular in the cannabis industry due to its high level of safety and cleanliness. CO2 extraction is used to extract valuable compounds from cannabis and hemp plants, including cannabinoids such as THC and CBD, and terpenes. This process involves subjecting CO2 to high pressure and temperature conditions, surpassing its critical point, and utilizing a controlled temperature and pressure to transform carbon dioxide (CO2) into a supercritical fluid state where it exhibits properties of both a liquid and gas.
One key advantage of supercritical CO2 extraction is the ability to preserve the full spectrum of cannabinoids, including CBD and THC, as well as the aromatic terpenes found in the plant material. Unlike some other extraction methods, CO2 extraction minimizes the risk of decarboxylation, ensuring that the valuable compounds remain intact.
CO2 extraction is recognized for its environmental friendliness, making it a preferred choice for socially conscious cannabis extractors. It leaves a minimal ecological footprint and produces clean, pure extracts that benefit both consumers and the planet.
