co2 extraction method

The CBD consumers will find myriads of products in the market, including edibles, topical, and vape oil, but they rarely stop to ask themselves about the source of the product. Many processes take place before finding a CBD product. The CO2 extraction method is the lead process that separates the compounds in a cannabis plant.

Note that there are over 100 compounds in cannabis, and it must go through a process to extract CBD out of it. Upon extraction of CBD, it goes through the next stage, where the manufacturer adds other ingredients which will work in synergy with CBD to deliver fantastic benefits. Are you ready for insights into the CO2 extraction method? Hold on and get the facts.

What is Hemp Extract?

Before we delve into the CO2 extraction method, let us understand what hemp extract is. When you run the raw buds of hemp through an extraction process, it results in oil-based concentrate extraction. The oil-based extract is the hemp extract sourced naturally in the buds.

Other desirable compounds are extracted together with the CBD, and they are effective in providing the synergy that users need when consuming the CBD. Companies can control the purity of the product by managing the potency level, consistency, and concentrations. The CBD in the raw hemp flower is not bioavailable, and you may want to heat it first to make it bioavailable.

What is the CO2 Extraction Process?

The CO2 extraction method is the most popular process that most CBD manufacturers use when harvesting the CBD from hemp and cannabis. It is an advanced process that needs special equipment to deliver the best results. The process involves three stages in three chambers; chamber one contains raw hemp material; chamber two will have pressurized C02, and the last chamber for collection.


The pressurized C02 is pushed through the section that contains natural hemp, and the end product is pure CBD. The method is efficient because it does not interfere with the chemical stability of the compounds.

Explaining CO2 Supercritical Extraction Method

The CO2 extraction method is a supercritical process that separates compounds independently while the process is on. It is necessary to have a stable temperature and pressure in a single run to give rise to a pure combination at a go. The CO2 extraction process also has Eden’s hi- Flo system. It is easy to achieve fractionation through this process because of its series of extracts and separators lines.

Note that every separator line experiences have varying pressure intervals. As CO2 flows through the separators, the first separator line set on high pressure will separate compounds because they have different molecular weights. Note that compounds will drop out at other pressures, and that strategy is capitalized in the CO2 extraction process.

When using a standard fractionation scenario, the wax fixes at some points in the first separator. The heavy resins are set at the second separator, and the light oils are finally on the third separator line. The varying weights make it easier to separate the compounds at ease.

Benefits of CO2 Extraction Method

The manufacturer is in total control when using the CO2 supercritical extraction process. The manufacturer may even opt to recycle the CO2 making the process economical and environment friendly. The FDA does not have any issues with CO2, and they have already labeled it as safe.

Co2 extraction

Manufacturers consider CO2 extraction as the best because of the high yields. CO2 extraction also allows the manufacturer to adjust the product’s physical properties, meaning that you get what you want. In instances where there are residues in the extracts that you get, it will evaporate.

Note that the quotes you get will improve when you mix them in food. There is no residual content that may contaminate the contents you get. The C02 supercritical process does not subject the plant to extreme temperatures, and therefore it won’t hurt the chemical structure of the CBD.

CO2 Extraction Method Equipment

The extraction system size will vary depending on the batch size. Note that some systems are automatic, and the manufacturer does not need to be there during the extraction. The supercritical CO2 extraction method will take longer than other available methods. The time elongation is a result of continuous fluctuations in temperature and pressure.

Before the extraction process begins, you ground the plant material and place it in the extraction vessel. The CO2 gas is then passed through temperatures, and the pressure then forces the CO2 through the pump to the extraction vessel. The extraction vessel meets the plant breaking the trichomes, allowing it to dissolve part of the plant material.

The pressure release valve in the vessel then allows the material to flow into a separate container. Here you will find the internal compressor and the heater, which will adjust temperature and pressure. The change in pressure and temperature allows the molecules to bond with Co2, separating them from the plant. Other systems will then reroute the CO2 back to the tank for use in the next batch while he extracts it in a beaker.

Why Use Supercritical CO2 in Cannabis Extraction?

  • Supercritical CO2 is cleaner and greener, making it best for consumers and the planet.
  • CO2 is a tunable solvent allowing the producer to incrementally tune its salvation strengths to get the clear CO2 supercritical fluids.
  • It is the safest and commercially viable method for extracting cannabis oils and CBD.
  • It can manufacture several end products.

The supercritical extraction method is now among the acceptable means for extracting CBD from hemp, and FDA already affirms it as the safest mode of extraction.

Is CO2 Extraction Method Safe?

The supercritical CO2 extraction method is becoming the popular and preferred method for extracting CBD from cannabis. The initial setup is costly, but once it gets done, it is cost-effective. Producers have total control over the procedure, and you can recycle it. It makes it an excellent option for people intending to safeguard the environment. The most notable milestone with using the supercritical CO2 extraction process is that it already has food and drug administration approval.

Bottom Line

The supercritical carbon dioxide (C02) extraction method is the best for all manufacturers. It is the best way to process hemp and cannabis to get CBD. If you need pure isolates or relatively pure quality CBD products, you want to try this best extraction method.
