Economic analysis of environmental problems in textile dyeing units: a case study from Ranaghat, West Bengal

0
The dye and dye intermediaries industry is an important segment of the chemical industry that provides inputs to a large number of industries. Currently, the Indian dyestuff industry is in the midst of a major restructuring and consolidation phase. With the emphasis on product innovation, rebuilding and environmental friendliness, this industry is increasingly moving towards greater customer orientation. Given the dynamic nature of the dyestuff industry in India and its tremendous potential, this study aims to conduct an economic analysis of the industry, with specific reference to its inherent environmental problems. The scope of the study was limited to a study of some units in Ranaghat, a town in the Nadia district of West Bengal. The potential environmental problems and the health hazards arising as results of dyes and dye production have been investigated. A case study of a dyeing unit in Ranaghat is presented, highlighting the negative impact on the water quality of its adjoining river, followed by some suggestions on ways of handling the pollution problem. A cost–benefit analysis of a dyeing unit in Ganganagar, and application of the results to the dyeing industry in Ranaghat, is also reported. The study also suggests some policies for consideration.
