Turning circular ambition into industrial reality
The plastic waste challenge is real. Demand for circular plastics is growing driven by increasingly ambitious recycled content requirements across major markets such as the EU’s Packaging and Packaging Waste Regulation (PPWR), EPR schemes in the US, and India’s Plastic Waste Management.
Many chemical recycling projects face challenges on the path to scalable, predictable, and investment-ready deployment:
