This study investigates the potential of Chirich (Asphodelus aestivus) tuber, one Turkey’s natural resources, for sustainable bio-hybrid film production. Bio-hybrid films developed from tuber starch in composite form with polyvinyl alcohol (PVOH) were thoroughly examined their physical, mechanical, and barrier properties. During production process, twin-screw extrusion hydraulic hot pressing methods employed; films’ optical, chemical, performances analyzed through FT-IR spectroscopy, water vapor permeability, solubility, mechanical tests. To evaluate durability against environmental factors model properties, advanced computational algorithms such as Gradient Boosting Regression (GBR), Random Forest (RFR), AdaBoost (ABR) utilized. The results showed that GBR algorithm achieved highest accuracy 99.92% R2 presented most robust terms sensitivity to factors. indicate tuber-based exhibit significantly enhanced strength performance compared conventional corn starch-based biodegradable polymers. These superior properties make them particularly suitable industrial applications food packaging medical materials, where durability, moisture resistance, gas characteristics are critical. Moreover, biodegradability integration into circular economy frameworks underscore sustainability, offering a viable alternative petroleum-derived plastics. incorporation ML-driven optimization not only facilitates precise property prediction but also enhances scalability By introducing an innovative, data-driven approach material design, this contributes advancement bio-based polymers applications, supporting global efforts mitigate plastic waste promote environmentally responsible manufacturing practices.
