“…For the treatment of wastewater from the dye industry, advanced oxidation processes, membrane filtration, microbial technologies, bio-electrochemical degradation, and photocatalytic degradation have been documented (Gao et al, 2023;Iqbal et al, 2023;Verma et al, 2023). In addition to assisting in the treatment of wastewater, innovative techniques including microalgae cultivation, biobased adsorbents, and membrane technologies also aid in the recovery of dyes and pigments that may be reused and recycled sustainably (Eskikaya et al, 2023;Xiong et al, 2023). Wastewater phytoremediation represents a promising circular economy-based approach for wastewater reclamation, resource recovery, and generation of value-added products.…”

Global demand for freshwater is rapidly escalating. It is highly essential to keep pace with the necessities of the increasing population. The effluents of wastewater are gradually identified as a reservoir of resources for energy generation and economic boom. Henceforth, most wastewater and sludge have great potential for reuse and recycling. The re-utilization and valorization of wastewater and sludge contribute to accomplishing sustainable development goals, combating water scarcity, and alleviating adverse environmental impacts of wastewater on the environmental components. The present article highlights the most novel approaches for wastewater treatment for the waste valorization of different industrial origins and the generation of value-added products and recovery of biopolymers, vitamins, enzymes, dyes, pigments, and phenolic compounds. We highlighted the life cycle assessment and techno-economic analysis. In addition, we have addressed a critical overview of the barriers to the large-scale application of resource recovery strategies and economic, environmental, and social concerns associated with using waste-derived products.

“…Te Fenton reaction process involves the reaction between hydrogen peroxide and iron which further produces reactive oxygen and hydroxyl species that enhance the degradation of pollutants in the absence or presence of light (photo-Fenton) [90]. Eskikaya et al [91] studied the degradation of BR18 and RR180 using the hydrochars obtained from laurel leaves and watermelon peels and observed removal efciency of 98.8% and 99.8% within 60 min and with 100 mg•L −1 initial dye concentration. Magnetic Fe 3 O 4 -NIO calcium alginate beads were prepared by Ayed et al [92] for the degradation of Novacron blue dye.…”

In recent decades, the textile industry has contributed to continuous pollution in the environment. Synthetic dyes which are commonly found in waste water are azo, sulfur, anthraquinone, triphenylmethyl, indigoid, and phthalocyanine derivatives. These pollutants block the light penetration in water bodies and prevent photosynthesis activity, thereby affecting aquatic life. As an environmental crisis, several technologies have been explored to control pollution. Among all the techniques, the photocatalysis process is considered as a green, simple, and economical process. To improve the photocatalytic activity, researchers worldwide have investigated various photocatalysts such as metal oxides, metal ferrites, and heterostructured nanocomposites. The major goal of this review article is to propose a high-performing, cost-effective hybrid photocatalyst reported to date for prospective azo dye pollutant remediation. This review article also aimed to highlight the challenges and uncertainties associated with dye degradation in the photocatalytic process.

“…With the development of modern industry, the composition of industrial wastewater has become extremely complex, making water contamination highly problematic. Inappropriate wastewater treatment incorporating dyes can directly affect regional water quality, thereby threatening environmental and human health [ 1 , 2 , 3 ]. Of all the efficient treatment processes for organic colorants [ 4 , 5 , 6 , 7 , 8 ], the Fenton-type heterogeneous oxidation process involving Fe 3 O 4 nanoparticles represents one of the most advanced and successful treatment technologies and has been extensively investigated for the removal of organic dyes with high efficiency coupled with the non-selective decomposition of organic pollutants [ 9 , 10 , 11 , 12 ].…”

A magnetite chlorodeoxycellulose/ferroferric oxide (CDC@Fe3O4) heterogeneous photocatalyst was synthesised via treated and modified cotton in two steps. The designed nanocomposites were characterised by FTIR, TGA, XRD, SEM, and VSM analyses. The Fenton-photocatalytic decomposition efficiency of the synthesised magnetic catalyst was evaluated under visible sunlight using Methyl Orange (MO) as a model organic pollutant. The impacts of several degradation parameters, including the light source, catalyst load, irradiation temperature, oxidant dose, and pH of the dye aqueous solution and its corresponding concentration on the Fenton photodegradation performance, were methodically investigated. The (CDC@Fe3O4) heterogeneous catalyst showed a remarkable MO removal rate of 97.9% at 10 min under visible-light irradiation. (CDC@Fe3O4) nanomaterials were also used in a heterogeneous catalytic optimised protocol for a multicomponent reaction procedure to obtain nine tetra-substituted imidazole derivatives. The green protocol afforded imidazole derivatives in 30 min with good yields (91–97%) at room temperature and under ultrasound irradiation. Generally, a synthesised recyclable heterogeneous nano-catalyst is a good example and is suitable for wastewater treatment and organic synthesis.
