Green Pathways to Functional and Renewable Polymeric Materials

Prof. Dr. Katja Loos, Rijksuniversiteit Groningen

Recent advances in polymer chemistry are opening genuinely green routes toward functional, renewable and recyclable polymeric materials. One major avenue is the use of biocatalysis (enzymes) for polymerization of monomers derived from renewable feedstocks. For example, enzymatic polycondensation of biobased diacids (e.g., furan-based) and diols or diamines affords polyesters and polyamides under mild, solvent-efficient conditions, enabling tunable architectures, controlled end-groups and enhanced degradability. These approaches demonstrate how enzymatic polymerizations can replace harsher conventional catalysis, align with renewability goals and facilitate downstream recycling.
In parallel, strategies for chemical or physical recyclability have been explored. Designing polymer backbones (and architectures) with end-of-life pathways in mind—including depolymerisation, enzymatic degradation or selective recovery of monomers—enables “circular” material lifecycles without sacrificing performance. Additionally, the integration of dynamic covalent networks or vitrimer-type behaviour has emerged as a key element: reprocessable, self-healing and adaptable polymer systems derived from biobased monomers or segments enable functional materials that combine renewability and reusability.
