The tremendous increase in agro-industrial waste poses major environmental problems and highlights the need for innovative, sustainable solutions. One promising solution would be converting these organic wastes, such as unvalued pineapple peels (ANA) brewer's grains (ECB), into activated carbons to meet impending challenge of wastewater treatment. In particular, Acid Orange 7 (AO7) is one most widely used synthetic dyes, a significant portion which ends up water, posing health with limiting decentralized cost-effective To address two challenges, we investigated best conditions wastes alternative (named CA-ANA CA-ECB) AO7 dye removal under representative adsorption conditions. Extensive characterization (SEM, EDX, XRD, BET) revealed an amorphous, mesoporous structure specific surface areas 1150-1630 m2 g-1, outperforming majority other biomass-derived reported removal. Adsorption followed pseudo-second-order kinetics Langmuir isotherm, record efficiencies 90-99% concentrations 25-35 mg L-1 batch reactor, driving forces being electrostatic attraction, π-π interactions, hydrogen bonding. These results undoubtedly highlight potential current waste-derived solutions efficient
