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
