"Cheap fashion, however, has a cost. The World Wildlife Fund has estimated that it takes 8,500 litres (2,245 gallons) to raise 1kg (2.2 pounds) of cotton lint– enough to make one pair of blue jeans. The use of pesticides and fertilizers, in addition to water, makes the global textile industry one of the most polluting and waste-generating sectors in the world ... The future of textile recycling lies in the supply chain, not retail stores. Plenty of companies boast about apparel made from PET bottles, but when that item of apparel is no longer wanted, its disposal once again becomes a nagging issue. Further complicating the sustainability of the global fashion industry is that recycling textiles is problematic." (Quoted from article)
