Avient Earns 2023 Re|focus Sustainable Innovation in Design Award for PCR Color Prediction Service
Avient’s Color Prediction Service (CPS) is the first digital tool of its kind that can illustrate the color possibilities or limitations of certain types of recycled resins (PCR) prior to laboratory trials.
As early adopters of our PCR Color Prediction Service, L’Oréal achieved consistent colors across various PCR grades in different countries, enabling them to launch with fewer color iterations and color trials, thereby reducing complexity and increasing speed.”

PCR Color Prediction Service simplifies and accelerates the selection of preferred colors for PCR content at varying levels, avoiding time-consuming trial and error.
OnColor™ IR Sortable Black Colorants include detectable colorants to allow reclaimed dark plastics, such as those found in food trays, to be detected and properly recycled by automated sorters.
Avient’s PCR Color Prediction Service helped L’Oréal simplify overall color development with recycled resin.
