Celanese POM ECO-C – setting a new sustainability benchmark in POM

DALLAS--(BUSINESS WIRE)--Dec. 9, 2025-- Celanese Corporation (NYSE: CE), a global leader in specialty materials and chemicals, has achieved Carbon Footprint Certification (CFC) from International Sustainability & Carbon Certification (ISCC) for its Hostaform® and Celcon® POM ECO-C grades at production sites in Frankfurt, Germany, and Bishop, Texas - expanding its network of certified facilities to empower customers to reduce product carbon footprints and accelerate the transition to a circular economy. This milestone underscores Celanese’s commitment to sustainability and innovation.

Advancing Lower-Carbon Solutions

This certification is the result of Celanese’s major investment in Carbon Capture and Utilization (CCU) technology at its Clear Lake, Texas facility as a part of its Fairway Methanol joint venture with Mitsui & Co., Ltd. - one of the world’s largest active CCU plants. The process captures CO₂ emissions and converts them into methanol, reducing fossil-based inputs without compromising material performance.

Key Highlights:

• Certified Sustainability: ISCC CFC certification provides third-party verification of carbon footprint reduction.

• Performance Retained: POM ECO-C maintains hallmark properties - high stiffness, thermal stability, sliding performance, and wear resistance - now with the lowest carbon footprint POM to date.

• Global Reach: Certification at Frankfurt and Bishop strengthens Celanese leadership in sustainable engineering plastics.

Digital Transparency with Chemille® - Digital Assistant

To complement these efforts, Celanese now provides Product Carbon Footprint (PCF) letters via AskChemille.com, its digital assistant for advanced material selection and support. By integrating certain Life Cycle Assessment (LCA) data into the Chemille® platform, Celanese delivers greater transparency and enables customers to make informed, sustainability-driven decisions while supporting Greenhouse Gas (GHG) emissions awareness.
