Closed-Loop Extraction

What does “Closed-Loop Extraction” mean?

An industrial method of creating cannabis concentrates. In general, extraction solvents are used to pull material from flower; in closed-loop extraction, these solvents are kept internal to a system and never exposed to air, allowing for reuse of solvents and better safety for manufacturers.

Example usage:

“I exclusively buy concentrates made using closed-loop extraction since it's a safer process.”
