Innovative Approaches to Recycling Mixed Plastics.

Researchers have developed a dynamic crosslinking technique that can compatibilize immiscible mixed plastics, allowing for their recycling and upcycling. The technique involves incorporating reversible covalent bonds into the polymer network, which can be broken and reformed under certain conditions. This allows for the creation of materials with both thermoplastic and thermosetting properties, enabling their reshaping and remolding. The approach could contribute to the development of a circular economy for plastics.
