For the last few years, the search for potentially sustainable green nanomaterials has been a challenge for the medicinal, cosmetics, electronics, and environmental industries. Green nanomaterials are a boon for worldwide environmental sustainability owing to their cost-effective, environmentally friendly, and socially acceptable nature. Most of the materials and synthetic procedures used for nonrenewable resources generate undesirable, harmful, and dangerous wastes. Therefore, the development of green nanomaterials using a suitable combination of nanomaterials and general green chemistry practices has been encouraged. Nanomaterials are predominantly exceptionally small, with a size range in nm and a high surface to volume ratio. These potential materials are attractive because of their distinctive properties, such as their structural, morphological, optical, and electronic characteristics. The design of these nanomaterials can be achieved via natural resources, biological processes, and nonhazardous solvents/solvent-free and energy-efficient techniques that reduce toxic wastes during large-scale production. Furthermore, outcome of large production of nanomaterials can be highlight in terms of minimize environmental impact using green chemistry principles. Metal nanomaterials mostly have a reducing nature and are costly, tremendously reactive, and lethal to the surroundings. So, instead of metal nanomaterials, green nanoparticles embedded natural resources can be used, as they are ecologically reactive and cheaper, with well-organized, interesting structural morphologies and eco-friendly natures. Energy consumption and raw materials (chemical/biological) are notable in green nanomaterial synthesis and lead to environmental impact during the production, utilization, and release throughout the whole life cycle. In view of constant advancements in the green nanomaterials field, this chapter deals with novel green nanomaterials, life cycle analysis, environmental impact, ongoing challenges, and future prospects. © 2022 Elsevier Inc.
