“Supercritical (liquid) CO2”
There’s no such thing as supercritical (liquid) CO2. The critical temperature is the temperature above which it can only exist as a gas regardless of the pressure.

They are using liquid CO2 under appropriate pressures to operate at room temperature, mixing the herbal matter in a pressure vessel to get the extract. The CO2 boils off, leaving a relatively pure extract of cannabinoids, without the other impurities associated with other organic solvents. One process uses “dry ice” as the co2 source.
