Denim Pollution In the Blue Jean capital of the world

The Pearl river on the banks of Chinese town of Xintang in Guangzhou– also known as the Blue Jean capital of the world – looks like this when seen from a satellite.. The river has actually turned blue black with a large portion of denim production wastes being discarded into the river. The town is an amalgamation of thousands of textile, denim and dyeing facilities. The denim is also being made here by traditional dyeing methods where cotton yarns are being dyed by dipping them into small(hot) indigo baths as against the factory dyeing of denim by Rope Dyed or Slasher dyed methods. This kind of cottage dyeing produces more indigo waste and the small dyeing units are not equipped with the requisite water treatment facilities.
