Abstract – Rajasthan is a desert prone area. People in this area are always in search of some means of earning livelihood. Fabric Dyeing is one such option for earning livelihood. Dying industries are very common in western belt of Rajasthan including Jodhpur Balotra, Pali and nearby places. These industries discharge many toxic substances in the form of unused dyes (approximately 50%) in the nearby water bodies. These colour bearing heavy metals as are non degradable remain in water and affect aquatic life and human life adversely.As they are water soluble they enter the living entity at the cellular level,and is responsible for bioaccumulation and biomagnifications in the complete food chain. These heavy metals if present beyond a permissible level in human beings are responsible for serious health disorders. Therefore before discharging this polluted water anywhere, it should be treated carefully to make it less harmful to the living world. Adsorption is one such method to treat this waste water. Activated carbon is taken as an effective adsorbent but has limitation with heavy metals. To make the method inexpensive, easy, cost-effective and ecofriendly, naturally available waste material can be used. This paper deals with the usage of the waste left as fruit and vegetable peelings, agricultural by-product waste, egg shells, etc. as adsorbents to remove heavy metals and colours from waste waters.
