Hemp and CBD

Hemp & CBD application: supercritical CO₂ extraction (scCO₂) for cannabinoids and terpenes—solvent-free processing delivering purity, safety, repeatability, and premium-grade extracts.

Hemp & CBD: Purity and Potency Through Supercritical CO₂ Extraction

A clean extraction process for premium hemp and CBD products

Supercritical CO₂ extraction has become one of the most advanced and sustainable methods to isolate cannabinoids and terpenes from hemp. Unlike traditional solvent-based techniques, it uses carbon dioxide at high pressure and moderate temperature to selectively extract active compounds—without compromising their integrity or safety.

This method is particularly well suited for producing full-spectrum CBD extracts as well as purified isolates used in the nutraceutical, cosmetic, and pharmaceutical industries.

Why choose supercritical CO₂ for hemp extraction?

Hemp contains a wide range of bioactive compounds, including cannabinoids such as CBD (cannabidiol), a non-psychoactive molecule whose therapeutic potential is increasingly recognized. Supercritical CO₂ technology enables precise and repeatable extraction of these compounds, ensuring both purity and consistency.

• Solvent-free extraction: CO₂ leaves no toxic residues, as it naturally evaporates during the process.
• Gentle processing conditions: extraction occurs at low temperature, preserving volatile compounds such as terpenes and fully supporting the “full-spectrum” effect.
• Adjustable parameters: by fine-tuning pressure and temperature, you can control yield, color, viscosity, and the cannabinoid profile of the final extract.
• Preservation of sensitive molecules: no harsh chemicals or high temperatures, allowing delicate plant compounds to be extracted without degradation.

Terpene retention and cold trap technology

With advanced CO₂ systems, aromatic terpenes can also be isolated from fresh hemp flowers before cannabinoid extraction. These compounds enhance flavor and aroma and may contribute to the entourage effect by improving the overall bioactivity of CBD products.

Using cold trap modules, terpenes can be collected during a separate step, offering maximum flexibility and a high degree of product customization.

From crude extracts to ultra-pure CBD isolates

Whether your goal is to produce a full-spectrum hemp oil or isolate CBD at a purity above 99%, supercritical CO₂ extraction is a clean and scalable solution. The process typically starts with a crude extract, which can then be refined through winterization, filtration, and CO₂-based purification steps.

Efficiency, safety, and sustainability

• Fast processing: a typical extraction cycle takes around 30 minutes, depending on biomass quality and target concentration.
• Eco-friendly: CO₂ is non-toxic, recyclable, and inert. It eliminates the need for hazardous solvents and reduces environmental impact.
• Safe operation: unlike volatile organic solvents, CO₂ is non-flammable and poses no explosion risk, improving safety for operators and facilities.
• Scalable systems: from lab units to industrial platforms, supercritical CO₂ equipment adapts to different production volumes, with modular designs that support future scale-up.
