ABSTRACT
The nanoscience is a promptly growing scientific field continuously achieving a great interest from the past few decades among the global scientists owing to the multidisciplinary nature and having bunch of applications. The green nanotechnology translates and update day by day their efficient synthesis techniques and application to focus on green synthesis. The nanomaterials synthesis has shifted to a greener approach due to the process of global efforts for the reduction of hazardous materials. The green wastes contain several significant constituents such as co-enzymes, enzymes, proteins, phenolic compounds, alkaloids, sugars and terpenoids. However, the new green alternatives are introducing very vastly, these biological agents (plant/microbes) work as a reducing and capping agents of metal ions to stable NPs, which leads to economical, and environmental benign condition. This chapter focuses on the exploration of current knowledge of green synthesis techniques of nanomaterials using green waste materials produced from domestic and industrial waste and their application due to their unique properties of surface plasmon resonance (SPR), adsorption, large surface area, etc. These green synthesised material having different unique characteristic properties due to the material shape, size, and crystal orientation along with the nature of surface functionalization. Another phase of the chapter also discusses the current scenario of materials, future challenges and their limitations to the industrial-scale synthesis of NPs for different applications in various sectors such as medicine, agriculture, environment and storage of food and beverage.
