Sustainability is a way that encourages not only economic growth but also promotes efficient, sustainable practices with effective solutions to protect our environment and our natural resources for the future. Polymer sustainability is, therefore, very important worldwide, with consumers, business leaders, and governments continuing to push for a circular polymer economy. Our research conference on Designing Macromolecules for a Sustainable Future targets advanced synthetic approaches and new characterization techniques, properties, and applications contributing to the circular polymer economy. We aim to bring eminent scientists working at the frontiers of polymers worldwide who will transfer and discuss the latest developments in the circular polymer economy.
