The global preference for plastics in consumer packaging has led to explosive growth and the production of hundreds of millions of containers for different applications per year. Along with the tremendous benefits that plastics bring to society, there is also a responsibility to ensure plastic waste does not end up in the environment. Ultimate is recognized by the Association of Plastic Recyclers and the European PET Bottle Platform for having no negative impact on the recycling stream.

With the recognition, OnColor™ NIR Sortable Colorants are preferred for high-density polyethylene (HDPE) resin in black and dark colors, according to the APR Design® Guide for Plastics Recyclability. OnColor NIR Sortable Colorants from Avient provide a solution to this problem, allowing the packaging to be visible to a NIR optical sorter, enabling it to sort into the correct plastic stream. Avient is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.
