CO₂ Extraction
Commercial-Scale CO₂ Extraction
Custom extraction plants, in-line dewaxing, developmental toll processing, and commercial partnerships.
Ways to Work With Us
Custom plant design and fabrication
A commercial CO₂ plant engineered and fabricated around your botanical.
In-line CO₂ dewaxing
Real-Time Winterization for the extractors you already run.
Developmental toll processing
Developmental volumes of your material, extracted and dewaxed for you.
Partnerships and licensing
New extracts developed together, and our process on your equipment.
Custom Plant Design and Fabrication
We have designed, fabricated and run our own distillation plants for decades. We bring the same work to commercial CO₂: we size the plant around your material and throughput, then engineer and fabricate it.
Methods developed at bench and pilot scale carry straight over, because the control is the same.
Real-Time Winterization
In-Line CO₂ Dewaxing
CO₂ extracts often carry plant waxes and fatty acids that are solid at room temperature. The usual fix is ethanol winterization: dissolve the crude extract in ethanol, freeze it, filter out the waxes, then evaporate the ethanol. It takes days, needs its own equipment and costs some of the compounds you were after.
Real-Time Winterization, developed by our CO₂ lead Jeremy Diehl, does that work inside the extraction run.
How Real-Time Winterization Works
Everything happens inside a standard CO₂ extraction run.
-
Extract
Botanical material is extracted under normal CO₂ extraction conditions.
-
Dilute
Right after the extraction vessel, fresh CO₂ is added to the stream, so the oil stays dissolved.
-
Chill
The stream is cooled until the waxes come out of solution, while the compounds you want stay dissolved.
-
Filter and collect
An inline filter catches the waxes. Clean, dewaxed oil flows on to the separators.
What Changes
Days back in production
Dewaxing happens during extraction, not as a separate step that takes days afterward.
Less equipment
No fume hood, cryogenic freezer, filter skid or rotary evaporator for winterization. A smaller footprint and a smaller team for the same throughput.
No flammable solvents
CO₂ is the only solvent, so there is no ethanol to buy, store or recover.
Full-spectrum oil
Light and heavier terpenes, sesquiterpenes included, are extracted and dewaxed in one run. The oil often needs no further processing.
Clean-up for existing oils
A standalone version dewaxes oils already extracted, including those made with other solvents.
Extracts That Carry Waxes
We have shown single-pass extraction and dewaxing on vanilla. Other good candidates are spices, frankincense and other resins, citrus peel, flowers and concretes, hops, tea and coffee: anything you winterize with ethanol today.
Developmental Toll Processing
Send us your botanical and we extract, dewax and fractionate it on our systems, then return the extract to you. We work at developmental volumes: enough for samples, evaluation and first trials before you invest in equipment.
Partnerships and Licensing
We work with fragrance houses, flavor companies, extractors and brands. You bring the idea, the botanical or the plant; we bring CO₂ systems, methods and decades of raw-material experience.
Our process, your extractors
Real-Time Winterization brought to your commercial CO₂ line under a partnership or licensing agreement.
Co-developed extracts
A new CO₂ extract designed around your product and your specification.
Fractions on specification
Light, middle or heavy fractions, separated to the profile you need.
From extract to finished product
Through Project Fragrance, an extract can become a finished fragrance or product.
