Solvent-based extraction methods produce high-end cannabis products that are popular among the masses. Products such as hemp oil, rosin, and hash rely on their extraction methods using butane, ethanol, or propane. These solutions and practices come with the risk of environmental damages and harmful vapor exposure for processors.
Due to the risks associated with solvents, solventless extraction methods are better for a few reasons and continue to produce strong yields.
What Is Solventless Extraction?
It’s essential to distinguish the difference between solventless and solvent-free. While solvent-free has residual chemicals released, a solventless extraction method is one of the most common methods and uses other resources to complete the extraction process.
Water is a familiar medium used to separate the plant from its trichomes. Processors know that some terpenes dissolve in a water base, while resin heads may not.
The Pros of Solventless Extraction Methods
A bonus to the solventless extraction process is that it is environmentally friendly while also producing strong yields and viable end results. Another benefit of this method is how quickly it can produce these yields with consistent quality. A few other pros to solventless extraction include:
- Over time, the repeated use of solvents can deplete the ozone levels and pollute water resources because of the volatile organic compounds (VOC).
- A solventless method displays fewer hazards from start to finish and further emphasizes the safety of the consumer without the risk of passing any residual solvents on.
- The results may vary due to the medium used, but solventless rosin is producible from the cured cannabis flower, trim, or kief.
The Different Methods
You might be wondering what to use or do if you don’t use a solvent. These alternative solutions play a significant role in why solventless extraction methods are better due to their impacts from growing to the consumer. Here are a few ways to consider:
- Rosin Presses. Cannabinoids and terpenes undergo heat and pressure for extraction. The rosin press technology allows beginners and commercial operators to utilize this method.
- Cold Water Extraction. Water, ice, and agitation extract and preserve concentrates, cannabinoids, and terpenes. To avoid damaging the integrity of the original plant, this method avoids heat and pressure.
- Ultrasonic-Assisted Extraction. By combining sound waves and water, the plant’s cell walls break down and emulsify. UAE is a good option as it pairs with other extraction methods and can create more potent results.
Take into consideration the final product’s quality before choosing the best method for your operation. With a solventless process, you ensure consumer safety, decrease the environmental impacts, and uphold an organic procedure from start to finish.
