Abstract: The global polymer waste crisis is intensified by the fundamental contrast between recyclable thermoplastics and intractable thermosets. This article comments on how vitrimers—polymers containing Covalent Adaptable Networks (CANs)—are bridging this recycling gap. The current research focuses on engineering vitrimers from both traditionally unrecyclable thermoset matrices and high-volume commodity thermoplastics. We detail the unique chemistry that allows these materials to be reprocessed, reshaped, and self-healed while maintaining structural integrity. Specific innovations include the scalable chemical protocols that chemically upcycle complex waste streams into high-purity molecular feedstocks. Vitrimers establish a scalable, chemical foundation for achieving true closed-loop circularity across the entire polymer value chain.
