Abstract
Among the different substances containing organic compounds, dyes are considered the most important class, and they are now an essential requirement in the modern world, mostly in the textile industries. In addition to the textile colouring, they are used in automobile, leather, paints, paper industries, etc., but their importance in the textile industries is maximum. Because of huge demand of dye, the production of a variety of dyes with advanced properties has drastically increased. Since dyes are complex aromatic organic compounds containing conjugated double bonds, they are highly toxic to the biological community of the world. In this chapter, more emphasis is given for synthesis technologies of various kinds of dyes, different kinds of hazardous pollutants generated from the dyeing industries, and their environmental impact along with the implementation of the technology developed to reduce the pollutant and its effect to our sustainable environment. Hence, more focus has to be given for manufacturing and application of dyes from renewable natural resources.
