RE:RE:RE:Fresh propaganda [00059] Cannabis extraction at cold temperatures with organic solvents has been shown to increase the purity of the product due to the decrease of undesirable components in the final cannabis extract. However, heat used during the evaporation step to eliminate traces of toxic solvent in the final product alters the cannabinoid and terpene content.
[00060] The inventors have found that a highly polyunsaturated lipid-based solvent can be used at cold temperatures (e.g., 0°C to -40°C) to extract cannabinoids and/or terpenes from Cannabis plant material. Benefits of these methods include, but are not limited to, one or more of the following (or combinations thereof): it is significantly less expensive and more efficient than supercritical fluid extraction; it is materially safer than extractions using organic solvents; it is faster and safer than traditional methods; and it is capable of producing significantly more potent end products than traditional methods.

NL has patented their own custom made closed loop system that uses Cryo-ethanol. There isnt really anything to discuss here - either there tech will have value or it wont. Value will be determined by the market - not by discussion boards.
I know you and Stealth have a back and forth thing going - but the rest of the NL board dont need to be involved. Doesnt matter who started it.
