As a responsible fashion company we are committed to do what we can to reduce our environmental impact and act with both people and planet in mind. Ismail Demir, Global Product Developer at Lindex Bangladesh office, is one of the colleagues working on the sustainable denim project. As the denim expert he is, we let him answer a few questions!
In general the challenges for denim production are the same as within textile production in total; all textile production requires a lot of water, energy and chemicals. But in denim production the consumption is intensified with the many washes needed to get the right look. As denim producers we need to alter and reduce production methods that has a negative impact on the environment and for us, the biggest denim challenge is to drop some washes and change the recipes at the same time as we achieve the right look.
To give denim the fashion look that we want, it often requires many technical processes like dyeing and stone washing for example, which are water and energy based processes. That’s why denim is consuming even more water, energy and chemicals than other garments. Many washes equals much water, and as washes usually are heated it also means much energy. Some of the washes contains coloring and chemicals, and with much water in the wash more chemicals has to be used.
Sustainable denim means that, besides using sustainable cotton, the washing process is made more efficient where we have been able to decrease the amount of washings for each item. When less water is used, less energy is normally consumed to heat up the washing water and less chemicals has to be added.
