Sustainable polymers is a multidisciplinary research field focused on the design, synthesis, characterization, and application of polymeric materials engineered to minimize environmental impact across their lifecycle. This encompasses the investigation of polymers derived from renewable resources, the development of materials with enhanced biodegradability or high recyclability (including advanced closed-loop and self-healing capabilities), and the evaluation of their performance as environmentally compatible alternatives to conventional fossil-fuel-based polymers in various sectors.
