Agree to disagree. With ethanol extraction, the cost is less; you get a better yield; the extraction is safer and uses much less power; and boasts more lenient storage limits. This translates into a higher extraction yield with up to twenty times the capacity and volume of alternative extraction techniques. It is also safer and more cost-effective when carried out correctly and can eliminate the need for dewaxing or winterization. It is a slower technique, however, given its higher boiling point and slower rate of recovery in post-processing.
Ethanol extraction is simple to set up and requires a low-power operation, representing an energy consumption of just 20% of carbon dioxide techniques.
Carbon dioxide extraction, by comparison, can only dissolve oil-soluble components. The drawback of this is the increased likelihood of extracting water-soluble components such as chlorophyll.
The fact that Canbiola has created a 99.9% pure cbd product, and has all lab documentation to prove it is what's important IMO.
Cheers.
