Polymers play a crucial role in modern society, serving diverse applications from packaging and textiles to medical devices and automotive components. The development of biodegradable polymers like polylactide (PLA) and polycarbonates is noteworthy for their sustainable advantages over traditional plastics. These materials can biodegrade and depolymerize under specific conditions, reducing environmental impact and supporting the circular economy through improved recycling and waste management practices. PLA, known as a "bioshopper" material, derived from starch fermentation, is esteemed as one of the greenest polymeric materials. Polycarbonates and PLA are exploited in Theranostics and medical fields. PLA slow biodegradability and biocompatibility make it ideal for drug delivery systems and pharmacokinetic control applications, whereas polytrimethylene carbonate well known biocompatibility made it one of the most exploited polymers in tissue repairing and engineering fields.
