Fabrication of biodegradable kraft paper from buffing dust and jute fiber: Green solutions for packaging

Abstract Addressing solid waste recycling, this study aims to develop biodegradable kraft paper from buffing dust (BD) and post‐consumed jute fiber (JF). Employing a simple solution casting method with polyurethane binder, the was fabricated characterized using UV–Vis spectroscopy, FTIR, XRD, SEM, TGA, OTR, biodegradability, tensile tests. The findings revealed covalent hydrogen bonding between BD JF, forming uniform surface. Notably, composite exhibited improved thermal stability, enhanced gas barrier properties, biodegradability compared individual components. Furthermore, also showed 57% higher strength, 38% greater elongation, 20% increased hardness, 9% density dust. Compared fiber, increases were 125%, 91%, 30%, 19% respectively. Moreover, excelled in performance, surpassing JF by remarkable 61% 73% increase These significant underscore vast potential of as versatile material suitable for various applications, including packaging, interior furnishing industries, reinforcing elements footwear industry. By addressing management promoting sustainability, research contributes development eco‐friendly materials that align contemporary environmental concerns. Highlights Covalent enhance uniformity. Biodegradable properties. Impressive hardness. Versatile applications. Promotes sustainability management.
