“…The XRD pattern contains no extra peak confirmed that ZnO nanoparticles synthesized are pure and there is no impurities is it. Also, it can be concluded that Zinc oxide has a good degree of crystalline structure due to the presence of sharp and narrow peaks in the XRD spectrum as shown Fig.5 [13,14].…”

The paper reviews synthesis of ZnO nanoparticles using Aristolochia bracteolata leaves extract. The Zinc oxide nanoparticles were characterized using the following methods. Biosynthesized ZnO nanoparticles were primarily confirmed by change in colour from brown to white. Ultraviolet-Visible Spectroscopy of the ZnO nanoparticles showed surface plasmon resonance (SPR) peak at 377 nm. Fourier Transform Infrared Spectroscopy was used to key out the specific functional groups present in the leaves extract. The X-ray powder diffraction the structural phase of the ZnO nanoparticles was found in the form of face centered cubic (FCC). The particle size of the synthesized Zinc oxide nanoparticles has confirmed. Field Emission Scanning Electron Microscopy analyses revealed that the synthesized ZnO nanoparticles were shape and size was confirmed and the Energy Dispersive X-ray analysis spectrum showed peaks for the presence in the range 8.5 keV. The synthesized nanoparticles were analysed to know the average size 50 nm were confirmed . The both gram positive and gram negative bacteria such as Staphylococcus epidermis, Bacills subtilis and Klebsiella pneumonia were experienced to analyse the antibacterial activity of the ZnO nanoparticles. To analyse the antifungal activity of the ZnO nanoparticles with the help of fungi called Candida albicans and Candida vulgaris.

“…Nava et al addressed the effect of different amounts of Camellia sinensis extract on the synthesis of ZnO nanoparticles. The synthesized nanoparticles were studied in photocatalytic degradation of methylene blue (MB) dye where the nanoparticles presented MB degradation over 84% in 120 min [81]. In another study, Parkia roxburghii extracts have been used for the synthesis of ZnO nanoparticles, and they were found to be efficient in degradation with nearly 98% efficiency in 8 min for both MB and Rhodamine B (RhB) dyes [82].…”

ZnO-based nanomaterials have been proven to be of great use for several leading applications since the beginning of nanoscience due to the abundance of zinc element and the relatively easy conversion of its oxide to nanostructures. Nowadays, ZnO as nanoparticles, nanowires, nanofibers as well as plenty of other sophisticated nanostructures takes place among the pioneer nanomaterials employed in the photovoltaic systems, fuel cells, and biomedical fields. Nevertheless, optimizing energy consumption and being eco-friendly are the challenging requirements that are still to be overcome for their synthesis. Green chemistry has been strongly presented recently in the scientific arena as an adequate potential alternative; worldwide investigations have been held on subjects involving bacteria, fungus, or algae-based synthesis as efficient options, and some of the intriguing scientific findings on this subject are reported hereafter.

“…Their performance for antibacterial activity was tested against Gram-positive and Gram-negative bacteria, showing the best action on Vibrio anguillarum, for which it could have promising applications in aquaculture (Xu et al, 2015). Zn(NO 3 ) 2 was reduced to ZnONPs with extracts from different fruits and the solids obtained were tested as catalysts for the photocatalytic degradation of methylene blue under UV light (Nava et al, 2017a), outperforming commercially available ZnO. The films showed good features as UV light barrier as well as an antimicrobial, for which they could be used in food packaging (Orsuwan et al, 2017).…”

Summary As the availability of fossil‐based resources declines, there is an impending necessity of finding alternative feedstock able to secure the production of fuels and chemicals. Exploitation of biomass as renewable source of chemicals is an attractive possibility, in particular the one derived from food waste (FW). Every year, large amounts of waste are generated within or at the end of the food supply chain at the consumers use stage and hence its valorisation attracts great attention. FW has proven a valuable feedstock for its exploitation to produce a wide array of intermediates and products with promising applications in industry, owing to their similar performance with respect to established products. These include organic acids and furans (generally used as platform chemicals to further products); polymers like bacterial cellulose, polyhydroxyalkanoates or chitin; biosurfactants; biolubricants; or nanoparticles. This overview covers the latest trends in chemical, enzymatic and biotechnological processes reported in literature on the production of these chemicals and materials, with a focus on the use of FW as raw material.
