“Phillips 66 is committed to keeping plastics out of the environment and driving toward a more circular economy where plastics packaging is reused, recycled or recovered,” says Zhanna Golodryga, executive vice president of emerging energy and sustainability at Phillips 66. “The ISCC PLUS certification highlights the company’s resolve to create sustainable streams for waste materials and to support the growth of advanced recycling in plastics.”

ISCC is a globally applicable and industry recognized sustainability certification system that covers all sustainable feedstocks, including circular feedstocks produced from plastic waste. Its ISCC PLUS certificate covers bio-based and recycled, or circular, raw materials.

The ISCC PLUS certification verifies the refinery meets the standards to process pyrolysis oil made from hard-to-recycle waste plastics into circular ethane, circular propane, circular propylene and other sustainable feedstocks and petrochemical building blocks. The products will be used to support polymer producers – including Chevron Phillips Chemical Co. LLC, Phillips 66’s 50-50 joint venture – that are advancing a circular economy for plastics.

Sweeny Refinery is the second Phillips 66 refinery to achieve an ISCC PLUS certification and the first for the processing of waste plastic pyrolysis oil into circular feedstocks. Its Humber Refinery in the U.K. is ISCC PLUS certified to process used cooking oil, food waste and other circular feedstocks.

Phillips 66, headquartered in Houston, manufactures, transports and markets products across its midstream, chemicals, refining, and marketing and specialties businesses.
