However, it is complex and requires advanced data to more accurately predict how a material will realistically perform in an end-use application. Avient Corporation, a premier provider of specialised and sustainable material solutions and services, has invested in testing equipment, personnel, and software to help its customers gain insight into its unique material solutions and how they perform.

In a successful circular economy, consumers are aware of what happens to their goods and products once they no longer need them, they know exactly how to reduce their waste, and what to do with something after it’s been used. Last but not least, individuals must rethink how they use products and commit to lifestyle changes that will have economic and environmental benefits for everyone. Connect with us to learn more about how Avient can deliver specialized material solutions that keep pace with the ever-increasing demands for sustainability and support the creation of a circular economy.
