Ethanol Solvent Recovery in Hemp or Cannabis Distillation
As the cannabis, and hemp, industries grow, many large-scale manufacturers are finding ethanol to be the most efficient extraction method. As an extraction solvent, ethanol has proven to be effective, efficient, and safe to handle.
Could the Grass Valley area be a center for the CBD extraction industry, and, if Proscere Bioscience actually exists, maybe they assemble systems using components from firms like TruSteel?
Just a thought.
