Avient’s technical representatives worked with the tool
maker to provide insight on venting, gate placement and other
tool design concerns to minimize the potential for any tool-
related problems.

Our goal in 2024 is to fully automate this process and expand
the PCF data available for the Avient portfolio.
Continuous improvement efforts led Avient to initiate a targeted assessment of 460 suppliers and our 20 largest customers to assess carbon emissions data availability and reduction plans.
Sustainability metrics represent 2023 data or
12-month approximate values based on available data from reporting facilities and are often made in reliance on third-party supplier information.

In 2019, we launched our latest initiative, Core Leadership,
to help managers of people develop their foundational
leadership skills.
Our latest grades offer up
to 50% lower haze and reduced impact on the PET recycle stream
compared to previous grades.
