Today, there is the roar of sustainable material development around globe. Green nanotechnology one extensions sustainability. Due to its approach, green fabrication nanoparticles has recently surpassed their classical synthesis in popularity. Among metal nanoparticles, contemporary findings have demonstrated that bimetallic possess more potential for different applications than monometallic due synergistic effects two metals. So, we are presenting facile, one-vessel, and one-step phyto-fabrication Ag–Fe BMNPs using bud extract Syzygiumaromaticum. The synthesized were characterized by UV-VIS, XRD, EDX, FTIR, SEM. NPs underwent biological studies. radical scavenging was found be 64% 73%, insecticidal 80% 100%, respectively. Similarly, both exhibited good antibacterial activity. zone inhibition 100 mg/mL 1 cm against all bacterial species, i.e., K. pneumonia, E. coli, S. aureus. It 1.5 cm, 1.3 aureus, respectively, showing activity higher NPs. this study unlocks eco-safe, cost-effective, least-harmful methodology with SA medical agricultural fields, a step towards

Paper mills inevitably produce various pollutants, including chlorolignin, chlorophenols, chloroguaiacol, furan, cyanide, and heavy metals. These pollutants cause significant threats to aquatic terrestrial life. The pulp paper industries are looking for eco-friendly solutions the disposal of effluents during processing. Moreover, environmental management practices a key concern that may be addressed by removing these using suitable bioremediation techniques. Therefore, we have discussed several nanotechnology based sustainable technologies like use nanoparticles, nanomaterials, nanocomposites, nanoadsorbents, advanced methods such as electrocoagulation photocatalysis, which utilized elimination hazardous from industry effluents. This review finally includes critical insight into potential above-mentioned interventions mitigation contaminants industry. Nevertheless, there few limitations challenges toward implementation technologies, also in this review.
