Increased productions of waste from industries have persuaded in sustainable and naturally stable methods to reuse the waste. Utilization of wastes for the synthesis of nanomaterial is of significant importance due to its extensive variety of uses in various industrial sectors. This review focuses on potential options available for nanomaterial synthesis from waste produced by industrial activities and manufacturing processes. Possible application of industrial waste derived nanomaterial for the expulsion of organic and inorganic contaminants is discussed. Furthermore, the future opportunities and challenges in this emerging research area of converting industrial waste to nanomaterials are addressed.

“…At 1323 K, Na can be effectively separated from Na-rich slag by super-gravity, and the recovery rate of Na from anorthite can reach 97.09% [ 7 ]. Numerous studies have explored the extraction of Al and Fe cations using hydrochloric or sulfuric acid to produce inorganic flocculants [ 8 , 9 , 10 ]. Owing to their high efficiency, non-toxicity, strong adaptability, and low price, inorganic polymer flocculants are widely used for sewage treatment [ 11 , 12 , 13 ].…”

A synthetic flocculant of aluminum (Al) and iron (Fe) extracted from red mud (RM) has been widely used in sewage treatment, while the remaining RM residue has been ignored. This study aimed to synthesize polymeric aluminum ferric sulfate (PAFS) flocculant from RM by acid leaching and then use the acidified RM residue to produce an acid RM-based ceramsite (ARMC) by mixing bentonite, hydroxypropyl methylcellulose, and starch. Our results showed that sintering, reaction temperature, H2SO4 concentration, reaction time, and liquid-to-solid ratio had an obvious effect on the leaching of Al and Fe in RM, which was a necessary prerequisite for the efficient PAFS flocculants. At a PAFS dosage of 60 mg/L, turbidity and phosphate removal rates were 95.21 ± 0.64% and 89.17 ± 0.52%, respectively. When the pH value was 8.0, the turbidity and phosphate removal efficiency were 99.22 ± 0.66% and 95.98 ± 1.63%, respectively. Considering the adsorption capacity and mechanical properties, the best conditions for ARMC production included using 60% ARM and ceramsite calcination at 600 °C, with the BET surface area 56.16 m2/g and a pore volume of 0.167 cm3/g. Thermogravimetric analysis indicated that 400 °C was a reasonable preheating temperature to enhance the ARMC mechanical strength, as this temperature allows the removal of surface-adsorbed and constituent water. Under a scanning electron microscope, the ARMC appeared rough before adsorption, while relatively uniform pores occupied it after adsorption. Our conclusion will help to improve the zero-waste strategy of RM and speed up the industrial production of RM in flocculants as well as utilizing ARMC as a new type of adsorbent for phosphorus adsorption in sewage treatment.

Cellulose acetate polymer membrane was fabricated with Fe3O4@ZnO core‐shell nanoparticles through phase inversion technique to enhance the hydrophilic &antifouling properties. The morphology, crystallinity, porosity and surface area of the core shell nanoparticles incorporated membrane were examined using X‐Ray Diffraction (XRD), Fourier‐transform infrared spectroscopy (FT‐IR), High‐resolution scanning electron microscopy (HR‐SEM), High‐resolution transmission electron microscopy (HR‐TEM) /Energy Dispersive X‐ray analysis (EDX) studies. The contact angle measurement and wettability test prove the improvement of the hydrophilicity of the membrane with the addition of nanocomposite materials. Adsorption test were performed with the of model dyes such as Congo red (Anionic dye) and Malachite Green (Cationic dye) were investigated using Ultraviolet‐visible spectroscopy. The adsorption percentage against Congo Red (CR) and for Malachite green (MG) were found to be 93 % and 70 % respectively. Kinetic studies exhibits the rate of the reaction, for CR dye it shows R2=0.9471 and R2=0.8609 for MG dye, which obeys the pseudo first order reaction. In addition, the adsorption isotherm model as Langmuir shows that KI values are 0.00338(L/mg) and 0.0486(L/mg) respectively. Desorption studies exhibits the maximum desorption of dye for Congo red is 89 % and 83 % for Malachite Green.In a recyclability process, membrane material adsorbs 90 % of Congo red dye and 63 % of Malachite green dye.
