With the increased demand for textile products, the textile industry and its wastewaters have been increasing proportionally, making it one of the main sources of severe pollution problems worldwide. The implementation of increasingly stringent standards for the discharge of wastes into the environment has necessitated the need for the development of alternative waste treatment processes. This paper provides a critical review on the current biotechnological approaches available for textile effluent treatment using different microorganisms. Their advantages and disadvantages and hence their range of applicability are outlined. A review of research directed toward developing enzymatic treatment systems for solid, liquid and hazardous wastes are presented. A large number of enzymes from a variety of different plants and microorganisms have been reported to play an important role in an array of waste treatment applications.

'Save the Earth to save the future'. Right from the inception of urbanisation and industrialisation with advancement in science of technology, it was gradually realised that growth cannot be considered to be a good thing if we ignore the environment in which we live. The textile chemical processing industry has importance of its own, being one of the basic needs of society and currently it is in the midst of a major restructuring and consolidation phase with the emphasis on product innovation, rebuilding and environmental friendliness.
