The purpose of this study was to determine the feasibility of a zinc oxide (ZnO) manufacturing project through a green synthesis method using plant extracts Cassia fistula and then evaluate it from an engineering and economic perspective. Several economic evaluation parameters are analyzed to inform the potential production of ZnO nanoparticles, such as the length of time required for an investment to return the total initial expenditure (PBP), the condition of a production project in the form of a production function in years (CNPV), project benefits and so on. The results showed that the production of ZnO nanoparticles was very prospective. Technical analysis to produce 250 kg of ZnO nanoparticles per day shows the total cost of the equipment purchased to be 21,450.00 USD. PBP analysis shows that investment will be profitable after more than three years. This project can compete with PBP capital market standards because of the short investment returns. To ensure the feasibility of a project, the project is estimated from ideal conditions to the worst case in production, including labor, sales, raw materials, utilities, and external conditions.

Physical And Chemical

Zinc oxide is of significant importance for many industries due to its versatile properties, which have been enhanced with the production of this material in the nanoscale. Recent interest in the preparation of metal oxide nanoparticles using biological approaches has been reported in the literature. This technique known as “green synthesis” is an environmentally benign process than conventional methods like physical and chemical synthesis methods. Zinc oxide nanoparticles (ZnO-NPs) have been successfully obtained by green synthesis using different biological substrates like chitosan. Chitosan is biocompatible, biodegradable polymer having exclusive physical and chemical properties. Chitosan/metal oxide nanocomposite is a promising nanomaterial with enhanced properties for multiple functionalities. Therefore, this review discusses favorable approach in the formation of cross-linked Chitosan/ZnO nanocomposites attracting significant attention in various fields such biomedical due to their unique biodegradable, biocompatible, non-toxic nature. The use of biological sources, fabrication of green synthesized ZnO nanoparticles and its applications is briefly discussed. Overall, this review is a comprehensive study for the synthesis of ZnO-NPs using biological sources counting on their features and applications.

Leaf Extracts

Green synthesis nanoparticles were considered as an alternative effective resource instead of chemically engineered metal oxide nanoparticles. Using leaf extracts for green synthesis, essential for the reduction and oxidation process of the metals. Phyllanthus niruri (L.) and Aristolochia indica (L.) leaf extracts were used to synthesize yellowish brown coloured silver (Ag) and white coloured zinc oxide (ZnO) nanoparticles. Synthesized green nanoparticles characterized by different spectroscopic analysis (XRD, XPS, FTIR, PL) and TEM. Characterization results confirmed the particles morphology, size, structure and also their optical and photonic properties. Three different concentrations of Ag and ZnO NPs were analysed against three (gram positive) and five (gram negative) bacteria. Increased levels of green synthesized Ag and ZnO NPs showed increased zone of inhibition than amoxicillin (positive control). Our study proved that the green synthesized Ag and ZnO NPs showed similar unique physical and chemical properties with metal oxide nanoparticles but less toxic while their discharge into the ecosystem.

This present work describes the synthesis of LaCe co-doped zinc oxide (ZnO) nanoparticles (NPs) prepared by green method using Gymnema sylvestre (G. sylvestre) leaves as reducing as well as capping agent. Green synthesis method avoids inert gases, high pressure, laser radiation, high temperature, toxic chemicals etc. as compared to conventional method like sol-gel technique method, laser ablation method, solvothermal method, inert gas condensation method and chemical reduction method. The synthesized LaCe co-doped ZnO NPs was characterized by X-Ray diffraction (XRD), field emission scanning electron microscopy (FESEM), elemental analysis (EADX), Fourier transform infrared spectroscopy (FTIR), UV-vis spectroscopy and photoluminescence (PL). The LaCe co-doped ZnO NPs was tested against clinical pathogens such as gram positive G+ (Staphylococcus aureus and Streptococcus pneumoniae) and gram negative G- (Klebsiella pneumoniae, Shigella sydenteriae, Escherichia coli, Pseudomonas aeruginosa and Protus vulgaris) bacterial strains using agar well diffusion method.

The economic evaluation is one of the key points in building chemical industries. This paper presented a preliminary economic evaluation of the large scale production of zinc oxide (ZnO) nanoparticles using the sol-gel method, which is very useful for helping decision whether the fabrication of this material profitable or not. Particularly, the study was done by changing the cost of raw material, which was compared to several economic parameters such as GPM, PBP, and CNPV. The result showed that the project was profitable by increasing raw material cost below 100% from the estimated raw material cost, informing the fact for the prospective fabrication for fulfilling the demand of ZnO nanoparticles.
