The development of reliable and eco-friendly metallic nanoparticles needs some consideration on the chemical procedures involved in the synthesis of nanomaterials. The conventional methods in the production of metallic nanoparticles generate a large amount of hazardous byproducts. Thus, there is a need for ‘green chemistry’ that includes a clean, nontoxic and environment-friendly method of nanoparticle synthesis [1]. As an alternative, biological methods are considered safe and ecologically sound for the nanomaterial fabrication [2]. Therefore, in this review special attention is focused on the biosynthesis of nanoparticles from natural resources as compared as ordinary chemical method. Biosynthesis of nanoparticles using plant is a new development of green nanotechnology beneficial to environmental and to the plant itself. It also plays a significant role in the field of biology and medicine.

The article confers a scalable manufacturing process of Fenspiride HCl. 4-aminomethyl-1-(2-phenylethyl)-piperidin-4-ol is the main building block in Fenspiride HCl synthesis. The reported reagents for 4-aminomethyl-1-(2-phenylethyl)-piperidin-4-ol synthesis are costly, explosive, highly toxic, produce hazardous waste, and also need to be handled with most care. The paper introduces aqueous ammonia as an alternate reagent in Fenspiride HCl and used in 4-aminomethyl-1-(2-phenylethyl)-piperidin-4-ol synthesis. The new green chemistry aspect makes the process environment-friendly and cheaper. It also eliminates toxic, sensitive, and hazardous reagents and makes the process safe on uncomplicated on bulk scale production. The high pure Fenspiride HCl is obtained by following this process and meets the ICH limits with good yield.

Background: The protection of the environmental is very important to control and restore the quality of environmental media through the reduction or prevention of the pollutants. Due to the growing awareness of safety and environmental issues, the use of nontoxic, clean and eco-friendly ways to synthesize nanoparticles has emerged out of necessity. Methods: In this article, the following issues were considered: strategies of green chemistry, green chemistry metrics, waste management, green nanotechnology/nanoscience and characterization. Furthermore, the tables including the covered topics in terms of environmental analysis were also presented in the manuscript. Results: Green synthesis of nanomaterials is a safer, energy efficient and fast method that reduce the use of solvents reagents, and preservatives which are hazardous to both environment and human health. Conclusion: The fabrication of nanomaterials using green procedures is a clean, safe, nontoxic and environment-friendly method that increases its necessity and demand in the large-scale applications.
