Pharmaceutical personal care products (PPCPs) have increased in consumption due to the worldwide post-pandemic situation, marking them as chemical and pathogenic pollutants in significantly higher concentrations than ever in the ecosystem. Considering the inexplicable levels of these chemical residues discharged into the environment, concerns have been raised regarding their probable ecotoxicity to marine and terrestrial life. A further concern is the potential for developing and spreading antibiotic-resistant microorganisms and genes in aquatic ecosystems due to antibiotic exposure. Hence, knowing how these compounds impact aquatic ecosystem functioning is imperative, and thus is a critical area of research. The ecological risk analysis of PPCPs in aquatic ecosystems has been carried out using various strategies. Previous studies have reported numerous approaches for eliminating these PPCPs, including conventional treatment methods, activated sludge processes, generated wetlands, biological remediation, sequencing batch reactors, phytoremediation, and membrane bioreactors. In terms of green biotechnology approaches, the current research aims to discover effective procedures for removing PPCPs and their emerging resources as pollutants. Therefore, this review focuses on the over-extensive utilization of PPCPs and their emergent sources responsible for the contamination and environmental threat for future wastewater purposes. Further, as fungi and their enzymes and derivatives can remove pharmaceuticals and personal care products from wastewater through oxidation and several processes, they have attracted the attention of the scientific community due to their ability to remove PPCPs as pollutants and their status as emerging resources in wastewater. This review examines the fundamental approach and progress of the bioremediation of pharmaceutical- and personal-care-contaminated wastewater using fungal-based systems. It also discusses mechanistic approaches through hybridizing cultures and other biological systems with fungal strains, current technologies, and prospects for future research on PPCPs in wastewater treatment.

“…Meanwhile, numerous studies have reported that high-value-added products, including pigments, nutraceuticals, and lipids, as well as animal feeds and gas biofuels, such as CH 4 and H 2 , could be gained concomitantly with wastewater treatment by microalgal consortia processes depending on the type of wastewater treated and the culture conditions (Figure 2) [56,[89][90][91][92]. Additionally, the concept of an algal bio-refinery with wastewater treatment allows for the increased utilization of microalgal biomass when applied to biofuel production as well as allowing for long-term economic viability and the reduction in residuary wastes associated with wastewater treatment [93]. During microalgal-bacterial consortia wastewater treatment processes, it was observed that bacteria release EPS that mediate their aggregation with various microalgae [1,22,94].…”

Microalgae have been considered a promising and sustainable candidate for wastewater treatment and valuable bioproducts, such as feedstocks for food, nutrients, and energy. However, many challenging bottlenecks, such as low biomass productivity, expensive biomass harvesting techniques, and inefficient extraction of biofuels restrict its large-scale commercial production. Symbiotic relationships between microalgae and bacteria, also known as microalgal consortia, have proven to be effective solutions for mitigating technical and economic limitations. The natural and artificial symbiotic microalgal consortia combine microorganisms with various metabolic activities, which leads to valuable biomass production and the removal of nutrients, pharmaceuticals, and personal care products (PPCP) from wastewater. Many microalgal consortia have been applied for various wastewater treatments with reduced energy costs and higher efficiency in recovering valuable resources. In this study we review the present research status and prospects of microalgal consortia, emphasizing the associated mechanism of microalgae consortia cooperative symbiosis and its studies on diverse environmental and biotechnological applications.

“…Advanced oxidation techniques facilitate the breakdown of contaminants by using sustainable resources. Nanomaterials such as titanium dioxide and graphene oxide possess catalytic characteristics that enable the decomposition of organic substances, including colours, medicines, and insecticides [34]. The use of this application is of utmost importance in the restoration of water quality and the mitigation of the long-term presence of deleterious organic contaminants.…”

The increasing apprehension regarding water shortage and environmental contamination has heightened the pursuit of sustainable remedies in the field of water treatment. This detailed research examines the use of sustainable materials in water treatment systems. This study aims to examine the pressing demand for environmentally friendly and highly effective methods of water treatment. It comprehensively explores a diverse range of sustainable materials, encompassing both natural biomaterials and sophisticated nanomaterials. The evaluation of key features such as adsorption capacity, selectivity, and regeneration potential is conducted for each material, hence offering valuable insights into their suitability for the purpose of pollutant removal and water purification. The present study provides a critical evaluation of the appropriateness of these sustainable materials by an examination of key criteria like adsorption capacity, selectivity, and regeneration capabilities. The aforementioned attributes, which are crucial for the elimination of pollutants and unwanted substances, highlight the significant contribution of these materials towards the progression of water purification methodologies. In addition to their practical attributes, the analysis explores the ecological consequences and enduring viability of these substances, emphasising the need of mitigating detrimental impacts on natural systems and their associated services. The evaluation further evaluates the environmental consequences and long-term viability of these materials, placing emphasis on their contribution to addressing water-related difficulties. By integrating the most recent research discoveries and technical progress, this literature review not only provides a thorough examination of sustainable materials used in water treatment, but also emphasises potential directions for further investigation and improvement in this crucial field.
