Implementing sustainable materials in engineering and manufacturing sectors enhances functionality while simultaneously addressing waste valorization and environmental concerns. This study presents the clean-technology approach for composite fabrication using agricultural waste materials, such as banana, sugarcane, and areca sheath fibers converted into reinforcement materials. These waste-derived fibers were hybridized with E-glass fiber and a bio-resin system comprising Lannea coromandelica plant gum and epoxy. This approach supports solid waste management goals, reduces reliance on petroleum-based resins, and may contribute to sustainability and circular economy goals. To further enhance environmental and engineering functionality, nano-silicon dioxide (SiO2) fillers were incorporated in different weight proportions (1.5, 3 and 4.5 wt.%), and three stacking sequences were developed: Banana/Glass/Banana (B/G/B), Sugarcane/Glass/Sugarcane (S/G/S), and Areca/Glass/Areca (A/G/A) fabricated via compression molding.
