The systems
Engineered for clean, repeatable runs
Cold by design
Chilled ethanol leaves waxes, lipids and chlorophyll in the biomass, so the crude needs far less winterisation downstream.
Closed-loop recovery
Integrated recovery reclaims the ethanol every cycle, cutting solvent spend and keeping the process clean and consistent.
Built to scale
One method from a 10 L pilot unit to 2000 L production, so output grows without changing how your team works.
From the floor
What operators tell us
We moved our botanical line onto COMERG's ethanol system and cut the winterisation step almost entirely. Throughput landed where they said it would.
MKM. Koleva
Production Lead, contract extraction
Straight answers while we were sizing the line. George's team walked us through the recovery setup before we bought, not after.
DRD. Roussev
Operations, nutraceuticals
Two years in and the unit just runs. When we have a question the support reply comes back the same day.
