A method used in cannabis extraction to safely and efficiently extract cannabinoids and terpenes from the plant material using solvents like butane, propane, or CO2. The system is called “closed-loop” because the solvents used in the extraction process are recycled and reused in a sealed, controlled environment, minimizing the risk of explosion, environmental impact, and solvent loss.
