Indigo Dyeing

Chemicals are one of the main components of our clothes

Heavy use of chemicals causes massive freshwater and ocean pollution, as well as soil degradation, which poses great threat to global food security


Synthetic Indigo needs caustic (bleach) and hydrosulfite (a toxic substance), creating millions of gallons of waste water in the dyeing process


These are then washed away into to nature causing detrimental environmental impacts


Today, less than 30% of the World's denim Mills use "pre-reduced " indigo which is the most sustainable dyestuff on the market.The rest use powdered indigo which creates more sludge and slurry in the waste water.


What can you do about it? 

Look for brands with water recycling capabilities


Look for brands that dispose of sludge in an ethical manner


Look for brands using foam dyeing methods and aniline free dyes
