The green synthesis of nanoparticles is a process where there is nothing environmentally unfriendly. Nanoparticles can be produced from plant and other biological waste materials. Many research was done before by using reducing agents such as NaOH, NaHCO3 etc. These materials cause the environment pollution. Using NaHCO3 result in producing CO2 also. But by using different organic waste materials the synthesis procedure can be turned into green synthesis. This study provides a detailed analysis of nanoparticle synthesis using a variety of plant-based materials, such as peels, leaves, and other biological waste. By comparing different plant extracts, we aimed to identify the most effective options for nanoparticle production, focusing on factors like yield and surface to volume ratio. The nanoparticles in this research were created using green methods, and we investigated how the type of plant material influenced the characteristics of the resulting nanoparticles, including size consistency and efficiency of synthesis. Our results of cross sectional analysis will indicate that certain plant sources are more effective at producing nanoparticles with desirable properties. It was never examined by the statistical analysis. There are also other metallic wastes from where various metal oxide nanoparticles could be extracted, resulting in a downfall to environmental pollution. The analysis revealed important patterns that helped in selecting the best plant materials for green nanoparticle synthesis. This study highlights the potential of plant waste as a sustainable resource for nanoparticle production, advancing the fields of green chemistry and nanotechnology.
