Clariant, Borealis, and SINTEF demonstrated Clariant’s HDMax catalyst technology for upgrading pyrolysis oil from plastic waste into steam cracker-compatible feedstock.

Pilot-scale tests in Norway confirmed full conversion of contaminants and compliance with cracker-grade specifications in a single-step process, reducing complexity and energy use.

The collaboration advances circular economy solutions by enabling high-quality recycled feedstock for virgin polyolefin production, supporting sustainable plastics recycling and paving the way for potential commercial implementation.
