Solvent-based extraction (BHO, ethanol, supercritical CO2) uses chemical solvents to strip cannabinoids and terpenes from plant material. The solvents are then purged, but the process can leave residual solvent traces (regulated by OCM testing). Solvent-based methods are highly efficient — they yield more concentrate per pound of biomass — but the introduction and purging of foreign chemicals can affect the final terpene profile. Solventless methods (ice, water, heat, pressure) are more labor-intensive and yield less per pound, but produce concentrates that represent the purest expression of the plant’s genetics. LimeLine produces solventless exclusively; we believe the resulting product quality justifies the lower yield.
