| contents | <p class="MsoNormal"><strong><span>Background:</span></strong><span> The ecological and economic impacts of traditional nanomaterial manufacturing technologies are profound, and are mainly associated with the use of toxic substances, energy-demanding processes, and the production of toxic wastes. Such restrictions have continued to fuel the international quest to find viable, yet affordable substitutes. Green synthesis, as a concept, has become a plausible answer, and agricultural wastes such as fruit peels, lignocellulosic wastes and other wastes that are left behind in the plantation have become a ready and renewable source of raw materials. This practice is consistent with the greater concepts of the Circual Economy that supports the valorization of waste and resource efficiency. <strong>Aim and Purpose:</strong> The purpose of this review is to record and discuss how the use of agricultural biowastes as the main feedstock to synthesize silver nanoparticles (AgNPs) greenly has been changed, compared to traditional methods that used plant extracts as the starting material. In particular, it assesses green extraction technologies, explains the bioreduction mechanisms, and critically reviews the standardized life cycle assessment related to the production of biogenic AgNPs</span><span>. <strong>Discussion:</strong> Active phytoconstituent of agricultural wastes such as phenolics, flavonoids and lignin are effective natural reducing and capping agents, which help to form stable, biocompatible AgNPs with well-defined morphologies. These biogenic nanoparticles exhibit excellent multi-targeted antibacterial and antibiofilm effects against multidrug-resistant (MDR) pathogens, which indicates their therapeutic importance. In addition to biomedical uses, waste-derived AgNPs have significant potential in environmental purification, such as improved wastewater treatment, and nano-agriculture, e.g., seed nano-priming or nano-pesticides. </span><span>Although having these techno-economic benefits, there are a few obstacles to large-scale commercialization such as intrinsic variability of biowaste composition, absence of a standard in synthesis, and unaddressed ecotoxicity issues. <strong>Conclusion:</strong> Waste-to-nano-wealth paradigm is a scientifically promising and environmentally friendly approach to sustainable nanomaterial production. The way forward to maximize its potential is to focus on safe-by-design frameworks, optimized and scalable extraction protocols and global regulatory harmonization. The gap between innovativeness and scalability of green AgNPs in the laboratory and industrial setting will be important in ensuring that green AgNPs are translated into real-world solutions.</span></p> |
