All-cellulose composites offer a transformative route to sustainable, high-performance materials by uniting matrix and reinforcement within a single, renewable polymer. Produced entirely from cellulose, all-cellulose composites eliminate compatibility issues, simplify end-of-life recycling and enable full biodegradability. This presentation will outline advances in processing, structure-property optimization and application case studies. By integrating materials science with circular-economy principles, all-cellulose composites are poised to become the next generation of sustainable composites in the transition to a net zero future.
