We promote the use of more sustainable materials such as Tencel™ Lyocell, recycled polyester and recycled and organic cotton. When using cotton, we only use certified organic cotton or recycled cotton for our denim products. The organic cotton is grown without synthetic pesticides, defoliants, chemical fertilizers and free of GMOs in accordance with the principles of organic farming. Our recycled cotton is primarily made from pre-consumer material, which allows us to extend the useful life of the fibers already produced.

To make dyeing processes more environmentally friendly and resource-efficient, we are working to find solutions that are less water- and energy-intensive and minimize the use of chemicals. We therefore rely on improved dyeing technologies such as Dry Indigo® from Tejidos Royo, which uses no water and therefore produces no waste water that pollutes the local water supply. In addition, Dry Indigo® uses 65% less energy and 90% fewer chemicals than conventional dyeing methods.

We measure the environmental impact of our washing processes using the EIM (Environmental Impact Measurement) software from Jeanologia®. The EIM tool offers our suppliers the opportunity to measure the impact of processes and define specific measures for improvement. It evaluates the environmental impact in four individual categories: Water consumption, energy consumption, chemical impacts and worker health. The requirements for the assessment criteria were significantly raised in 2022 and, for example, the use of potassium permanganate (PP spray) and pumice stones was tightened. Both are used throughout the industry to achieve an authentic used look. This results in waste water contaminated with stone dust and chemicals, which puts a strain on sewage treatment plants and requires special disposal. Potassium permanganate (PP spray) can also be harmful to the health of workers.
