While our goal focuses on waste impacts from our direct operations, we also seek opportunities along our value chain to work with suppliers to reduce waste associated with shipping materials and with customers by offering products that incorporate recycled content or extend the useful life of a product. The plan includes a range of options, including repurposing scrap composite rods as fence posts, recycling of scrap glass, and recycling of composite finished goods. Avient’s global operations participate in Operation Clean Sweep, whose overarching goal is to ensure that every plastic resin handling operation achieves zero loss of pellet, flake, and powder.

The design team reached out to long-term supplier Avient GLS Thermoplastic Elastomers to help develop a customized solution. They selected a TPE-based impact modifier that could be used at a loading level five percentage points below the current material while still meeting all of the performance requirements, including higher stiffness.
