Phthalate extraction from waste PVC using supercritical CO2 is proven effective!

Phthalate extraction from waste PVC using supercritical CO2 is proven effective!

At Cescco2, we’re proud to share a breakthrough in sustainable polymer processing:

Together with leading researchers and forward-thinking partners, we’ve demonstrated that supercritical CO₂ (scCO₂) can efficiently remove harmful phthalates from flexible PVC waste—such as blood bags and cables—paving the way for safe, circular reuse of challenging materials.

✅ Non-toxic and solvent-free

✅ Mild process conditions (74 bar, 31 °C)

✅ High polymer quality retention

✅ Scalable and fully REACH-compliant

Many thanks to the research teams at the University of Groningen and ETH Zürich, and to all our industrial, governmental, and regional partners—your expertise, materials, funding, and belief in circular innovation made this milestone possible.

Let’s keep driving sustainable change—together. 🌍
