CO2 vs Solvent Extraction Safety Comparison

Safety is a top priority in industries utilizing **plant extracts, pharmaceuticals, and essential oils**. This article examines the **safety differences** between supercritical CO2 extraction and solvent extraction, focusing on toxicity, environmental impact, and workplace hazards.

1. Toxicity and Residues

• Supercritical CO2 Extraction: **Non-toxic**, with no solvent residues in the final product.
• Solvent Extraction: Uses **chemical solvents** like ethanol and hexane, which may leave behind **harmful residues**.

2. Workplace Safety

• CO2 Extraction: Operates in a **closed-loop system**, reducing exposure risks.
• Solvent Extraction: Uses **flammable solvents**, increasing **fire and explosion risks**.

3. Environmental Safety

• CO2 Extraction: **Eco-friendly**, as CO2 is **recyclable and non-polluting**.
• Solvent Extraction: Solvent waste disposal poses **environmental contamination risks**.

4. Case Study: CO2 Extraction in Essential Oils

An essential oil producer **eliminated solvent-related hazards** by transitioning to CO2 extraction, improving worker safety and product purity.

5. Conclusion

For **maximum safety**, **supercritical CO2 extraction** is the preferred method. Companies like **SHANGHAI NORTH BROOKS** provide **advanced CO2 SUPERCRITICAL EXTRACTION MACHINE** solutions that ensure a **safe and clean extraction process**.
