Versatile Fractionated Lignin from Rice Straw for Antimicrobial Elastomer Functionalisation and Hotmelt Adhesive Polyol Synthesis Without Chemical Functionalisation

Short Introductive summary

The transition toward a sustainable chemical industry requires the creation of biomass-derived platforms capable of generating multiple high-value materials through integrated chemical and catalytic pathways. Within this context, the work developed by INESCOP introduces an innovative platform based on rice-straw lignocellulosic fractions. Through mild organosolv fractionation and steam explosion pre-treatment, the lignin obtained maintains its natural phenolic and aliphatic hydroxyl groups, which enable its direct use as a functional polyol in polyurethane synthesis and as an active filler for antimicrobial polymer composites (SBR and TPU). This eliminates the need for chemical functionalisation, such as epoxidation or hydroxyl enhancement, simplifying processing and improving environmental compatibility. these components constitute a multi-functional biomass-derived chemical platform capable of producing bioplastics, adhesives, and bio-composites through scalable, energy-efficient processes. This integrated valorisation route demonstrates how a single agricultural residue can be transformed into platform chemicals and polymers, aligning with EUBCE Topic 6.3.
