Waste water contamination is ever increasing problem which the whole world is now facing. Industrialization and globalization has led to production and disposal of large amount of heavy metals in the environment. The tremendous increase in use of heavy metals over the past decades has inevitably resulted in an increase flux of metallic substances in the aquatic environment. Heavy metals are major pollutants in marine, ground, industrial and even treated wastewaters. Mining activities, agricultural runoff, domestic and industrial effluents are mainly responsible for the increase of the metals released into the environment. Tea waste has been utilized in agricultural field to enhance the production under heavy metal stress. After water, tea is the most widely consumed beverage in the world With great production and consumption large quantities of tea wastes( From the Caff,Cafeteria,or tea –processing factory) are usually discarded into the environment without any treatment. The main objectives of the review is to determine the effectiveness and feasibility of some low cost agricultural waste material (Tea waste, coconut husk and coconut shell) in the process of heavy metals removal from waste water

Keywords: Heavy metals, Tea waste, Industrialization, Waste water contamination.
