At Avient, we are proud to be a part of the solution, supporting the shift from a linear economy to a circular economy and driving sustainability for all of our stakeholders. The circular economy is a departure from the linear, take-make-waste system in which discarded goods and products end up in landfills once people no longer have a need for them. In general, people are still not sure exactly what they can do to support circularity.
