The study examines the conversion of lignocellulosic biomass, particularly lignin-rich residues from bioethanol production, into activated carbon as a high value-added material. Agricultural residues obtained from different feedstocks and processing stages were used as precursors, and their chemical properties were characterized prior to activation. The production process involved chemical activation and carbonization, and the effects of feedstock type and processing conditions on pore structure and surface properties were analyzed. The findings show that lignin-rich residues can be effectively transformed into porous activated carbon suitable for adsorption applications, highlighting their potential as sustainable raw materials for value-added carbon products.
