Creating one pair of jeans takes a lot of water and chemicals. One Swiss chemical company has developed a dying technology known as Advanced Denim that can save enough water to cover the needs of 1.7 million people per year if one quarter of the world’s jean makers started using it. The technique can produce a pair of jeans using up to 92% less water and up to 30% less energy than conventional manufacturing methods.
Advanced Denim uses one dying vat and liquid sulfur dye that requires just one sugar-based reducing agent, as compared to traditional techniques that may require 15 dyeing vats and a host of chemicals. The process, if used on a wide scale, could save 2.5 billion gallons of water per year, prevent the release of 8.3 million cubic meters of waste-water and save up to 220 million kilowatt hours of electricity.
