Abstract: The global shift toward a circular bioeconomy has catalyzed the transformation of agricultural, industrial, and synthetic residues into high-performance nanofibers. This study provides a comprehensive evaluation of recent breakthroughs in upcycling diverse waste streams into functional nanostructures. Quantitative data across multiple sectors confirms that waste-derived nanofibers frequently meet or exceed industrial benchmarks. Mechanical characterization of fibers isolated from agricultural sources shows crystallinity indices ranging from 60% to 85%, with tensile strengths consistently reaching or surpassing 100 MPa. Furthermore, the integration of synthetic waste fractions can enhance the flexural modulus of composites by more than 350%. In energy and environmental applications, carbon nanofibers derived from wood waste exhibit specific capacitances reaching approximately 1300 F/g, while porous membranes fabricated from recycled plastics demonstrate carbon dioxide capture capacities between 3 and 4 mmol/g. The efficacy of these systems extends to water remediation, with adsorption capacities for dyes and heavy metals often exceeding 350 mg/g, and some specialized systems reaching over 1000 mg/g. Additionally, the functionalization of nanofibers with bioactive extracts from food waste enables antibacterial inhibition rates up to 100% and cell closure efficiencies near 80%, proving their viability for clinical healthcare. While challenges regarding feedstock heterogeneity and processing energy intensity remain, the integration of green manufacturing and predictive modeling offers a robust pathway for the industrial realization of waste-derived nanofibers. This paper underscores the pivotal role of advanced upcycling in decoupling industrial growth from resource depletion, facilitating a resilient and sustainable manufacturing ecosystem.
