As witnessed worldwide, a rapid growth in research and creation of energy storage devices such as supercapacitor electrodes that can store deliver at very fast rate, provide high current short duration. This article deals with review on how (SC) electrode materials get developed from bio-waste like cooked chicken bone waste (CCBW), egg shells, fish gills, fishbone waste, biodegradable non-biodegradable marine wastes plastics, mangroves, chitosans, mussel shells which economic benefit for the substantiality technology. The synthesis preparation involved study include one step activation colloidal blending processes.The characterization as-prepared are carried out by implementing XRD, FESEM, EDS, FT-IR, TGA, TEM, RAMAN spectroscopy. It is visualized possess carbon content porosity leading to greater specific surface area highly essential conductance SC electrodes. Researches electrochemical analysis prepared using CV, GCD, EIS techniques have been analyzed.

In the coming years, escalation of waste discharge into diverse water sources is an inevitable trajectory. Despite numerous advancements in treatment technologies, pollution remains a persistent global crisis. Conventional wastewater processes have demonstrated limited efficacy eliminating organic and inorganic pollutants. Consequently, researchers are intensively directing their efforts towards advancing methods, propelled by urgent need to address rising environmental mitigate ecosystem damage. Among array methods previously explored, adsorption stands out as one most effective approaches for targeting pollutant removal. Activated carbon (AC), widely recognized low-cost highly porous adsorbent material, has been extensively employed globally. However, transformative era technology emerges with surface modification AC. Modification enhances characteristics such capacity, selectivity, promotes regeneration ability. This paper provides comprehensive overview recent methodologies undertaken AC through impregnation, utilizing various chemicals/modifiers, applicable studies. The study delves existing barriers commercialization, technological challenges, economic relevance associated application adsorption. Furthermore, it offers forward-looking future recommendations modified dynamic landscape treatment.
