Conventional dyeing of cotton uses an enormous amount of salt, which causes many sustainability problems. The Nano-Dye Process uses no salt which is a sustainable benefit.
The dissolved salt in the effluent after the conventional dyeing of cotton is binded back into a solid by adding an additional chemical to the water treatment plant. During the binding process unintended toxic chemicals in the effluent are trapped and toxic sludge is created. The toxic sludge is removed from the water treatment plant which results in a complex and massive solid waste problem
The Nano-Dye Process, by using no salt, drastically reduces the cost of recycling its effluent. Our no salt and fairly clean effluent makes zero discharge water treatment plants affordable and enables cotton dye plants to effectively operate a closed loop water system with 100% recycled water.
