Most of these industries are batch processes. These industries produce around 90,000 tons of dyes, out of which 10% is exported. Covering coastal areas of Maharashtra and Gujarat, these industries are located majorly in the belt of Ahmedabad to Chiplun. Coastal areas are preferred since these processes are water-intensive.
Other than water, the most common substance used in the dye industry is common salt. Why is this common salt a concern to us? Common salt if present in huge amounts in the effluent of these industries, can render good land to a barren one. Not to mention its corrosive power.
The E-factor of this industry is 50.
The total world market for dyes is a whooping 7 billion with a 2% growth rate. This growth rate is highly evident in populated nations like Asia. Dystar is one of the largest manufacturers of dyes.
Like any other industry, the dye industry faces issues like:
- water pollution
- air pollution
- land pollution
- waste management
- health and safety
In places like Ankaleshwar, Mahad, Parshuram, some parts of Dombivali, air pollution in monsoon is highly visible. For a person with asthma, these places can prove fatal. It is not just India, but China too, both have profound demographics.
So, what is the world doing about this?
