CONVERSION OF BLEACHING AND DYEING EFFLUENTS SLUDGE AND TEXTILE SPINNING MILLS WASTE INTO FUEL

Abstract

Increase in population and rise in industrial establishments caused increase in demand for water. Due to industrialisation and discharge of solid and liquid wastes the quality of water and soil are affected. One firm wastes are another firm raw materials. Waste is not a waste material but, it is resource to another. The wastes are to be collected, treated, stored properly and are to be reused by the other firms. Biological Effluent Treatment Plant (ETP) sludge from bleaching and dyeing unit, wood chips, droppings wastes, cotton mud waste from spinning mills and green waste are mixed proportionally and made as briquette in cake form of 120 mm x 120mm x 75mm which are having high calorific values more or less equivalent to coal. The cake is fed into boiler of bleaching and dyeing unit for producing steam. It is a successful project using waste materials by which the ecology and the environment is improved.
