Supercritical CO2 CBD Extraction

Newton Hill Labs is one of the highest capacity CBD Oil Processors based in the state of Vermont. The company is dedicated to producing and selling, through wholesale transactions, premium CBD oil, tinctures and topicals to service the exploding CBD industry globally. Newton Hill processes its own crude oil and refines it into a highly purified concentrate using a Supercritical CO2 extraction process.

Why Choose Us

Under current staffing, we are able to produce 400 Liters / month of Full Spectrum oil. We can easily scale up production to meet demand.

Facility

NHL’s facility is located at 107 Catamount Drive, Milton, VT. The 10,000 square foot concrete tilt-up facility, located on a 3.12 Acre lot, is zoned Industrial and hemp business uses. The facility has an electrical capacity of 4,000 Amps at 277/480V, which the Company believes is ample power to accommodate planned growth. Under current plans, all 10,000 square feet of the facility will be devoted to CO2 extraction operations and a 2,500 square foot mezzanine will accommodate all back-office operations.

Supercritical CO2 Extraction Process

We use a Supercritical CO2 extraction process which is widely considered the cleanest method of extraction. The process of C02 CBD extraction involves using pressurized carbon dioxide (C02) to extract natural cannabinoids, terpenes and oils from hemp biomass. When C02 reaches a certain temperature, it works as a solvent. Although heated C02 works as a solvent at higher temperatures, it is non-toxic and will not leave toxic left-over residue as a by-product in the finished CBD products. This is obviously one of the main benefits of extracting CBD with the C02 method. The downside is it is much more expensive than other CBD extraction methods. Supercritical C02 extraction will give a higher yield of CBD isolate per lb of hemp biomass.

The 7 Step Process

1

Extractor chamber filled with ground cannabis/hemp (trim).

Extractor chamber filled with ground cannabis/hemp (trim).
2

Pump forces pressurized

Pump forces pressurized carbon dioxide at the optimum temperature, and in the liquid supercritical state (ScCO2), into
the extractor chamber.
3

Dissolve

The supercritical carbon dioxide acts as a solvent with the cannabis, dissolving the cannabinoid compounds it contains.
4

Separation

The ScCO2 carries the cannabis oil particles past a pressure release valve into a separator.
5

Closed loop system

The carbon dioxide gas rises out of the oil and is routed back to the CO2 tank to be used again in a closed loop system.
6

Collection

The cannabis oil, waxes and resins descend in the separator where they are captured in a collection vessel.
7

Pure CBD-rich cannabis oil

The resulting substance is processed further into various products, such as pure CBD-rich cannabis oil, free of any solvents.
Automation Consistency

Quality Assurance

Newton Hill Labs only uses high quality biomass. All plant material is tested by a 3rd party lab prior to purchase and includes a Certificate of Analysis detailing the presence of any pesticides and heavy metals. At various stages during the extraction process, additional testing is performed to ensure consistent quality.
