The textile industry is water intensive and discharges numerous coloring compounds into the water body that depend on the industry’s geographical location, the wet processes used for manufacturing, processing conditions, and the substrates involved. Textile wastewater contains chlorobenzenes, phthalates, heavy metals, azo dyes, and chlorophenols that have severe health issues, such as being allergenic, cytotoxic, genotoxic, mutagenic, and carcinogenic threats to living organisms. The differing concentrations of sulfates, chlorides, TOC, TDS, TSS, BOD, COD, high pH, and dye content characterize textile wastewater. To protect the environment and public health, a higher concentration of these items in textile wastewater is needed to treat the textile wastewater effluent before discharge. The conventional treatment methods are not able to fully remove the pollutants, such as physical treatments can only remove grease, oil, and TSS, whereas biological wastewater treatment (aerobic and anaerobic) can only decrease colors, COD, BOD, oil, and phenol with a higher accomplishment period and by-products. Therefore, it is necessary to develop effective ecofriendly, cost-effective, novel techniques, such as membrane technology, and a promising method with fewer by-products. The activated carbon method effectively removes heavy metals and dyes from the textile wastewater, and advanced oxidation processes (AOPs) are a recent development in textile wastewater treatment processes. Combining AOPs methods has been proven effective in removing pollutants when combined with biological and advanced physical processes. This paper reviews the textile manufacturing process, textile wastewater characteristics, textile wastewater’s impact on the environment and health, and the available textile wastewater treatment approach.

The use of biodiesel is a proactive measure that can be implemented to reduce emissions of greenhouse gases and other adverse environmental impacts. However, one of the major setbacks to biodiesel production is its relatively higher cost compared to petroleum diesel. The optimistic solution to this is valorization of biomasses like waste chicken fat (WCF) and clay for deriving non-edible oil and catalyst respectively. Herein, we report the synthesis of clay derived SiO2 catalyst impregnated with SrO, Bi2O3, CuO and CaO. The developed catalysts were characterized by FTIR, XRD, and SEM. XRD studies confirmed the successful impregnation of active metallic oxide on SiO2 support. Further, these catalysts were employed for biodiesel production from WCF, and SrO/SiO2 was found to be most effective and efficient catalyst for biodiesel production from WCF. Hence, SrO/SiO2 was adapted to optimize the different transesterification reaction parameters such as methanol to oil ratio, catalyst loading, reaction temperature and time. The optimized conditions for maximum biodiesel yield 98.9% were found to be 65 °C in 1 h with 12:1 methanol to oil ratio and 1 wt% catalyst loading. The biodiesel produced was also analyzed by GC-MS. The obtained biodiesel yield shows that clay can be a potential, and cost-effective, catalyst source to produce biodiesel from WCF.

Sea buckthorn (SBT) combines very fascinating nutritional composition with vital vitamins (A, C, E, D, K, and B complexes). Flavonoids, sterols, α-carotene, linoleic acid, and many more unsaturated fatty acids are present in the sea buckthorn plant. The organic extract of SBT seeds is commonly utilized as an anti-aging ingredient in numerous cosmetics. SBT oil extracts are used in pharmaceuticals that treat diseases like diabetes, cancer, cardiovascular disease, and neurological disorders, in addition to cosmetology. In this investigation, various concentrations of organic solvents such as n-hexane, isopropyl alcohol, ethyl acetate, ethanol, methanol, and ascorbic acid (standard) were used for the extraction of oil from sea buckthorn seeds. The antioxidant activity of such extracts was checked by the iron chelating, commonly known as the ferric chloride (FeCl3) method, which is based on the ferric reducing ability of plasma (FRAP) assay with the help of UV-Vis. Our results indicate that seed extract of Hippophae rhamnoides, should be considered as a non-toxic source and the ferric reducing ability of plasma (FRAP) assay is used to evaluate the anti-oxidant potential by various organic solvents. The highest (68%) of FRAP is scavenged by the ethyl acetate and least (53%) of isopropyl extracts.

Recently, innovative developments have been made in the rapidly developing field of nanotechnology. However, toxicity due to long-term exposure to various types of metal-based nanoparticles, especially metal and metal oxide nanoparticles, is gradually increasing. The kidney is prone to toxin-induced impairment because it is one of the main organs for eliminating multiple potentially dangerous substances, including nanoparticles (NPs), from mammals. However, the mechanisms underlying cytotoxicity triggered by various NPs have not yet been reported. This review summarizes the various mechanisms involved in metal-based nanoparticle-induced nephrotoxicity, focusing on Reactive Oxygen Species (ROS) production, which leads to oxidative stress and apoptosis. The mechanisms by which metal-based NPs cause serious side effects in the renal system and the specific toxicity of different types of metal NPs are also summarized.

Textile effluents may harm the human body as well as cause environmental pollution. For several decadesresearchers have been attempting to overcome this issue by introducing environmentally friendly technologiesthat degrade bulk dyes to mitigate hazards. Synthetic dyes are carcinogenic for humans as wellas for other living organisms. Various techniques have been developed for the removal of these toxiccompounds, advanced oxidation processes (AOPs) being the most used processes. In this study,Montmorillonite (MMT) supported BiVO4 nanocomposite was prepared by the sol–gel method to degradeBrilliant Red 80 dye using photocatalysis. The BiVO4/MMT composite was comprehensively characterizedby several characterization techniques including X-ray diffraction (XRD), Fourier-transform infraredspectroscopy (FTIR), Scanning electron microscopy (SEM), Raman, Photoluminescence spectroscopy(PL), and UV–Vis diffuse reflectance spectroscopy (UV–Vis-DRS). Interestingly, the composite materialshowed a narrow bandgap of 2.26 eV with strong light absorption in the visible range. A 1000-wattXenon Lamp was used for activity performance measurement. The photocatalytic Brilliant Red 80 degradationactivity was observed to be 99% degraded within 120 min of illumination compared to conventionalBiVO4 which showed around 80% degradation. Moreover, in this work, an acidic media wasfound to favor the degradation of Brilliant Red 80 dye.
