I guess one might legitimately ask whether that 95% yield is from biomass to crude, or crude to distillate? My assumption is they’re just talking biomass to crude.
There are lots of other folks here with a better handle on the extraction efficiencies and economics of CO2… @ExTek90?
However, if you look at (for instance) the numbers Apeks put in their ROI calcs, they are aiming at 90% cannabinoid recovery. Folks doing cryo-ethanol are usually aiming there too. getting the last 10% requires more work. or more correctly, more solvent. so it takes more time & energy as well. are they pulling 95%? maybe. It can certainly be done. question is, is it worth the extra effort? I assume they’ve done the math, and chosen their target appropriately. I assume they’ve also chosen their temps/pressures/flow rates to make it work.
