Honeycomb extraction methods are currently hydrocarbon based, meaning we extract via solvent. The solvent we use in our hydrocarbon closed loop extraction equipment is N-Butane. We use a CP grade 99.8% pure N-Butane, and our system recycles it, not allowing any gas to evaporate into the atmosphere. Solvents used in our extraction process, are then purged from the oil, further refined and processed, leaving minimum/no residual solvents left in the final product requirements for hydrocarbon extraction companies. We are required to test every hash extraction batch that is produced, for residual solvents and potency. This system is a must to help eliminate our carbon footprint.
