Next-Generation (Bio)degradable and Bio-Based Polymers: From Molecular Design to End-of-Life Performance

Research in polymer chemistry is rapidly evolving to meet the demand for sustainable solutions as society transitions away from persistent, fossil-based plastics. Next-generation (bio)degradable and/or bio-based polymers have attracted significant attention for their potential to combine high performance with lower environmental impact. Central to this endeavor is the precise control of chemical structure, macromolecular architecture, sequence distribution, and the integration of functional additives or fillers. These factors dictate not only the fundamental properties—such as mechanical strength, barrier properties, and processability—but also influence how materials degrade, recycle, or persist at the end of their lifecycle. Despite recent advances, key knowledge gaps still remain: the connections between structure, processing, and (bio)degradability under real-world conditions is incompletely understood, and standardized methodologies for evaluating disposal scenarios are still under development.This Research Topic aims to advance the chemistry and engineering of next-generation (bio)degradable and/or bio-based polymers by elucidating the relationships between synthesis, structure, properties, and end-of-life performance. Particular emphasis is placed on new synthetic methods, molecular design strategies, innovative architectures, and the impact of these variables on processing and practical use. Contributions that offer mechanistic insight into degradation and recycling pathways, studies employing advanced characterization, and articles integrating predictive modelling or data-driven design are encouraged. The overarching objective is to support the development of polymer systems that combine rigorous chemical innovation with reliable, sustainable end-of-life options, thereby enabling applications across packaging, biomedical, engineering, and beyond.This Research Topic is focused on the chemistry, design, structure–property relationships, processing, and controlled degradation/recycling of sustainable polymeric materials. Articles addressing the following themes are particularly welcome:• Synthesis and macromolecular engineering of (bio)degradable and/or bio-based polymers.• Copolymer composition, sequence control, and advanced architectures (block, graft, branched, star).• Processing–structure–property relationships in sustainable polymer systems.• Role of functional additives, compatibilisers, and bio-based fillers in polymer blends and composites.• Morphology, crystallization, and their impact on material performance.• Advanced characterization techniques for structure and degradation analysis.• Hydrolytic, enzymatic, oxidative, and environmental degradation mechanisms.• Mechanistic studies and modeling of degradation kinetics and fragmentation.• Chemical and mechanical recycling strategies for next-generation polymers.
