Abstract
Plastics recycling has become an important issue based on the principle of sustainability and circular economy. Therefore, the development of a valuable chemical recycling method, to achieve the recycling process of end-of-life polylactide (PLA) waste without loss of material properties, meets unprecedented opportunities. In this regard, we propose a “DE–RE polymerization” strategy to achieve the recycling process from end-of-life PLA plastic waste to new virgin-quality PLA materials in a “polymer to polymer” mode. This approach improves the efficiency of PLA recycling and promotes the development of plastics reutilization.
