Recycling green polymer chemistry

This article reviews the enzyme-catalyzed polymerization and chemical recycling of biodegradable aliphatic polyesters, polycarbonates, polythioesters, polyphosphates, and polysiloxane, particularly highlighted for the nascent green polymer chemistry. 

The development of polymer-immobilized ligands and catalysts for asymmetric synthesis is a rapidly growing field [1], which has great importance due mainly to the easy separation and recyclability of polymer-supported catalysts. The polymeric catalysts also represent one of the most powerful tools for green sustainable chemistry, in the sense that they can be easily recovered and reused many times. 

Thus, the use of metal-loaded cross-linked CD-based polymers is part of a green chemistry approach for organic synthesis, as much for the versatility of the potential catalytic applications as for their use under microwave assistance and their recyclability. Furthermore, the high absorption of organic compounds in nanosponges, associated with their chiral environments, place this material for promising applications in sustainable chemistry.
