Ideally, denims or jeans would be made from traditional cotton which have their own share of carbon footprints. Each pair of jeans would require 42 liters of water as well as about 15 liters of dye which carry a lot of harmful chemicals as well.
But Dawn Ellams may have come up with a great alternative in the form of wooden pulps, which should be less harmful.
The process includes transforming the wood pulps into cotton-like fabric. The said jeans, named Tencel, would require only 1/5 of the usual water, energy and chemicals that traditional jeans would normally need.
