Agriculture waste-derived activated carbon has become a viable and renewable replacement for traditional activated carbon sources. This study examines the development, characteristics, and prospective uses of activated carbon derived from various agricultural waste products, such as crop residues, food scraps, and other biomass by-products. The use of these agricultural waste products shows a sizable potential for the synthesis of activated carbon and the impact of various activation procedures, including physical and chemical activation methods, on the structural and surface characteristics of the resulting activated carbons is discussed. Additionally, the composition, structure, and characteristics of activated carbon are evaluated with important variables, including activating agents, temperature, and impregnation ratio. Using agricultural waste helps to generate ecologically acceptable and sustainable materials while addressing important waste management issues.
