The quality and quantity of potable water resources can be significantly compromised by the rapid growth of industries and the unregulated discharge of wastewater into existing water bodies. Conventional treatment methods like biological treatment, adsorption, and advanced oxidation processes (AOPs) based on hydroxyl radicals have proven to be ineffective in eliminating persistent pollutants such as textile dyes. Furthermore, little attention has been given to dealing with the issue of sludge generated by these treatment processes. Recently, sulfate radical-based AOPs have emerged as an efficient method for degrading these hard-to-treat pollutants. Various methods have been explored for activating sulfate radicals in research, including thermal, alkaline, electrolysis, ultrasound, radiation, and the use of homogeneous/heterogeneous metal activators like Co, Mn, Cu, Ni, Fe, etc. It has been noted that the oxidative capability of sulfate radicals depends on how they are activated. However, in recent years, the use of metal-based catalysts has been found to introduce a secondary pollution risk due to the leaching of toxic metal ions. Consequently, efforts have been made to develop metal-free catalytic processes, and studies have shown the potential of carbonaceous materials for activating sulfate radicals through multiple pathways, including those previously reliant on metal-based activation. In this study, we have repurposed various waste materials into valuable products, such as carbonaceous materials, which can replace metal-based catalysts. This approach has proven to be cost-effective and helps reduce environmental waste. In this context, the research problem is defined with two primary objectives: utilizing waste-derived, value-added products for catalytic degradation of textile dyes using sulfate radicals and improving the reliability and effectiveness of the treatment by exploring the use of

acoustic cavitation and pulse power plasma. Overall, the study aims to identify, select, and assess various sulfate radical-based hybrid advanced oxidation technologies through a life cycle assessment to promote the reclamation of wastewater as a valuable resource.
