Solvent losses with ethanol extraction systems are a key cost contributor and drive a major increase in operating cost compared to CO 2 extraction systems. For example, CO 2 is 4 cents a pound compared to ethanol which is greater than $4 per pound. CostĬO 2 extraction is much less expensive to produce a kilogram of oil compared to ethanol extraction systems. This natural solvent also eliminates any unwanted emissions into the environment making the “clean and green” solvent in extraction systems. It also leaves out the potential risk for chemical residuals and contamination that are of concern with ethanol extraction. Because CO 2 is considered a natural solvent, a producer can more readily become a certified organic manufacturer. After the separation of desired cannabinoids, the fluid CO 2 is reverted back to a gaseous state leaving a “crude oil” containing CBD, terpenes and residual plant materials ready for distillation and product formulation.ĬO 2 extraction systems are by far the cleanest for consumer, producer and environment alike.

We suggest the use of lean techniques and Value Stream mapping to improve workflow, reduce inventory, and by extension reduce the headcount required to produce a unit. In reality most operations have a very low value-added labor in a very high overhead component to direct labor. Value added labor is the labor content that is spent by the laborer on direct conversion of the product into something the customer values. The concept of value-added Labor in this instance is very important. However different configurations of equipment and different workflows can improve labor content and headcount. The direct labor between the two techniques is essentially the same. What is the Labor Difference between Ethanol Extraction vs. This is a crucial factor in the CBD extraction process that allows for a complete extraction at an efficient throughput.

With the combination of special temperatures and pressures, CO2 reaches what is called a supercritical state. To put it simply, CO2 extraction uses pressurized carbon dioxide in select temperatures to pull desired cannabinoids from hemp biomass. For hemp extraction, CO2 is used to extract CBD oil from hemp biomass. This method is used to extract the essential bitter flavor from the house so that the flavors can be blended and preserved. Hops are used to brew beer and add flavor to beer. There are many other essential oil extracts that are used in the supplements industry that utilize this process. It can also be used to extract any botanical oil from any plant material. The most famous and successful industrial process for supercritical CO2 extraction is the coffee decaffeination process. Supercritical CO2 extraction is used in a wide array of extraction systems from essential oils to decaffeinated coffee.
