Evaluation of Molasses as a Green Reducing Agent in Sulfur Dyeing

The present scenario of water insecurity (poor availability and accessibility to clean and healthy water when needed) denotes the preponderance of environmental damage caused by effluents or waste runoff from industries, such as the dye and textile industries. The polluted waters have led to terrible and sonorous negative impacts on the ecosystem and econetworking, thus, urging for a sustainably suitable substitute to tackle and annul the noxious environmental constraint posse by the hazardous dye effluent. Several chemical and physical methods for treating dye effluent are now in use, but they are time‐consuming, expensive, and inefficient. Interestingly, nanoparticles have egressed as a superior answer for efficient dye removal and degradation, because of their chemical reactivity and exceptional surface characteristics. As a result, the use of metal nanomaterials in the treatment of dye runoffs has been thoroughly investigated. The study used major scientific databases such as SciFinder, Scopus, PubMed, Google Scholar, and Science Direct to conduct a comprehensive review of publicly available literature. Degradation, dye effluent, green metal nanoparticles, and water pollution were the keywords used to find scholarly papers. Efforts were made to figure out and explain the mechanism of dye effluent degradation, how long the degradation will take and how effective the use of plant biosynthesized metal nanoparticles for dye removal is. In addition, the role of bimetallic nanoparticles has also been investigated with remarkable feat from literature. The current level of knowledge about the mechanism and the use of plant biogenic metal nanoparticles in common dye effluent treatment is summarized in this paper.

“…It has been used in dietary applications as a sweetening and flavoring agent for food, as an ingredient for beer brewage, as an additive for composites, and as a green reductant for chemical reactions. [30][31][32][33][34][35] Although the price of molasses has been increasing year by year, unfortunately, ample amounts of it have been disposed of as sugar refinery factories' waste. [35] As a thickening agent and stabilizer, it causes a more homogeneous distribution of the metal oxide nucleates and reduces the size of the nanoparticles.…”

Microbial susceptibility of the denim fabric sized by starch raises some skin health concerns about this extensively used fabric. In this work, biocompatible antibacterial denim fabric is prepared by optimized green synthesis of the copper(I) oxide (Cu 2 O) nanoparticles on the cotton fibers. The copper oxide nanoparticles were synthesized without using any toxic chemical to reduce the copper salt. As an alternative, the waste of the sugar refinery factory, molasses, was used as eco-friendly and cost-efficient material. The antibacterial activity of the samples against Candida albicans as model fungus, Escherichia coli as Gram-negative, and Staphylococcus aureus as Gram-positive model bacteria is investigated besides cytotoxicity; also, the synthesis process is optimized regarding the most biocompatible and antibacterial nanocomposite. The characterizations prove the effectiveness of the molasses for reduction of the copper salt and formation of the copper(I) oxide (Cu 2 O) nanoparticles. Synthesis of the copper(I) oxide (Cu 2 O) nanoparticles has a positive effect on the mechanical properties of the nanocomposite. The results of this work introduce a green method for sustainable development of the fabric industry; it also presents a potential application for molasses and reutilizing it.
