Summary: The emergence and spread of new diseases caused by unplanned industrialization and the use of antibiotics has resulted in serious concerns regarding the remediation of wastewater containing antibiotics. In this study, a coral-shaped alpha-Fe2O3/ZnO/reduced graphene oxide composite photocatalyst was prepared from basil seed as a sustainable biomass resource. The photocatalyst exhibited excellent performance in the photodegradation of the antibiotic oxytetracycline (OTC) under visible light irradiation, achieving a degradation efficiency of 98% within 90 minutes.

Summary: Environmental concerns regarding industrial wastewater containing dyes have increased with industrial development. Decolorization of industrial effluents is crucial for color-free discharge. Biodegradation using laccase enzyme has emerged as a competitive method. Laccase, a green catalyst, exhibits high catalytic activity and has been extensively studied for dye remediation, but immobilization is necessary to fully utilize its potential.

Summary: Adsorptive-photocatalytic electrospun nanofiber membranes have shown great potential in wastewater treatment. However, their mechanical properties limit their use in pressure-driven filtration. In this study, dual-layered MoS2/PAN-CA membranes were successfully fabricated using electrospinning and hot-pressing techniques, resulting in improved physicochemical and structural properties. The MoS2/PAN-CA membranes exhibit promising performance in treating various pollutants in water and wastewater.

Summary: The study found that ternary nanocomposites have significant effects on degrading dyes in textile industries' wastewater under visible light. The Co-doped ZnO nanoparticles (ZnO@Co) doped polypyrrole ternary nanocomposite (Ppy/ ZnO@Co) showed highly efficient photocatalytic performance in degrading cationic rhodamine B (RdB) and anionic direct yellow 50 (DY) dyes under visible light illumination. The composite exhibited excellent photocatalytic recycling performance with over 97% removal efficiency for up to five cycles.

Summary: In this work, we reported the chemiresistive response of ZnO/PPy-Ag nanocomposite films at room temperature. These films showed high selectivity, outstanding sensitivity, rapid response/recovery time, and extremely low detection limit towards NH3 gas. The high sensitivity and fast response of the films can be attributed to the carrier-rich PPy-Ag layer, which controls the charge transport upon interaction with NH3 gas.

Summary: Under the background of freshwater scarcity, a low-cost cellulose membrane doped with silver nanoparticles was used to filter urban wastewater, reducing the amount of coliforms and Escherichia coli significantly. The filtered wastewater retained a high availability of organic matter and a significant percentage of inorganic salts, allowing it to be reused for domestic purposes and garden irrigation.

Summary: ZnO/Bi2WO6-CC layered heterostructures photocatalysts with different loadings of Bi2WO6 were synthesized on flexible carbon clothes substrate. The Z3B-CC (3 wt% Bi2WO6) showed the best photocatalytic effect, with a photodegradation rate of methylene blue as high as 96.9% in about 100 minutes. The type II band structure formed by ZnO and Bi2WO6 contributes to the excellent photocatalytic performance of this new layered heterostructure.

Summary: The study proposed an advanced microalgae-based process for treating sugarcane spent wash, recovering biomass for biodiesel production, and utilizing algal residue as a step towards waste management. The microalgae Coelastrella sp KJ-04 grown in spent wash showed high biomass and lipid production. The extracted lipids were converted to biodiesel and the de-oiled biomass was used to synthesize cellulose nanofibers, supporting a waste-free technology.
