Although the textile industry is one of the significant contributors to the global economy, approximately 10% of the annual global dye production, amounting to 7 × 106 tonnes and spanning a spectrum of 10,000 different dye variants, is wasted in the dyeing process and subsequently released into the environment. Following the dyeing and processing stages, this waste contributes to environmental pollution, making the textile industry account for 20% of the overall industrial water pollution worldwide. Traditional treatment of effluents is burdensome for the majority of textile units that are micro-scale enterprises. A significant challenge is that there isn't a single, commercially viable way to efficiently treat wastewater from textile industries. Scholars from several disciplines are working together to investigate novel approaches that are assiduously directed at addressing environmental issues by minimising waste, thereby promoting sustainability, circular economy, and industrial symbiosis. This study aims to address the challenges associated with the treatment process of textile dye-related effluents by conducting a comprehensive analysis of recent research on treatment processes and advancements and exploration of biotechnological treatment methods that are focused on achieving the reuse of treated water. The review covers different processes, traditional, current and emerging techniques, and it emphasises their use in practical situations. Also, the efficiency, specificity, and environmental friendliness of different biotechnological approaches are discussed offering a comparison of their benefits and drawbacks. A holistic remediation approach is advocated by harmonizing both conventional and non-conventional treatment methods for a more comprehensive solution.

“…This removal process can be achieved through various methods, including chemical precipitation, ion exchange, solvent extraction, and using materials with high adsorption capacity like chitosanbased substances. In their study conducted in 2021, El-shorbagy et al [68] successfully achieved the removal of toxic silver ions from water using adsorption with chitosan modified with RI and RII additives. In the presence of chitosan, they obtained 22.5% silver removal, 100% with RI-modified chitosan, and 92.6% with RIImodified chitosan [68].…”

As a natural, biocompatible and biodegradable polymer, chitosan is used for many different applications. Other important features of chitosan are its environmental friendliness, its renewable resource and its inherent high antimicrobial activity. It can be used directly or composites with other polymers in different forms such as spherical, layer, monolithic, particles, etc. Among these, chitosan coatings are applied in the form of thin films and membranes by methods such as solvent casting, electrospinning, dip coating and spin coating. Chitosan films are used in active packaging for the food industry, wound dressings, drug delivery systems and scaffolds for biomedical applications, water treatment and corrosion prevention for environmental applications. In this review, we focus on chitosan-based films, membranes and coatings developed specifically for biomedical and environmental applications. Firstly, information about chitin, chitosan and chitosan derivatives, functional properties of chitosan are presented. Subsequently, the preferred methods for the production of chitosan-based films were reviewed. In the last part, studies on chitosan films for environmental and biomedical applications and current status assessment were presented.

“…They have also demonstrated the importance of the green bio-sorption approach to applications such as toxic metal removal using the ion-exchange approach. 16 Another study used phosphoryl-functionalised algal-PEI beads and algae biomass to adsorb rare earths and molybdenum. 17,18 The agitation modes involved in mechanical, ultrasonic, and microwave techniques during uranium sorption using amine- and di-thizone-based magnetic chitosan hybrid materials were studied thoroughly.…”
