Nigeria and the world, by extension, generate enormous amounts of agricultural waste and residue. These wastes, which are inappropriately deposed off either by unplanned landfilling, burning or indiscriminate dumping, are a menace to society. In an effort to reduce the degradation and pollution load of these wastes on the environment, they are being geared towards recycling and reuse as a potential resource in meeting the increasing demand for easily attainable, cost-effective, efficient and environmentally friendly wastewater treatment alternatives. This study reviews the various adsorbent types and recent use of agricultural wastes as viable adsorbents in the society. The study therefore serves as a blueprint for the elimination of various contaminants from wastes.
