The adidas Sustainability Series
According to material scientist Dr. Alan Hudd, the dyeing and finishing processes in clothing production are responsible for 3% of global CO2 emissions. At adidas, we acknowledge that we’re part of the problem, so we’re teaming up with our suppliers to help them decarbonize their operations, which includes the introduction of low carbon coloration innovations.
Given our commitment to climate neutrality, it’s clear that this is an area of our business that needs to be addressed, which is exactly what we’re doing. How?
In fact, any technologies or innovations that we implement in our material coloration process must now consume less energy or bring about a reduction in CO2 emissions.
And things are going according to plan. We are on track to achieve our target for 2022, producing 8 million yards of material using three pioneering technologies: NTX™ Cooltrans™, Dope Dye and No Dye. So, let’s take a look at how they work.
Low carbon technologies that we can count on
NTX™ Cooltrans™ is a revolutionary textile coloration solution which can accurately color synthetic materials using significantly less heat and water than more traditional processes. It offers an almost identical appearance, feel, and functional performance as conventionally dyed fabrics, and it works very much like a printer. Currently, this solution can be applied to lightweight synthetics, but we’re looking to expand it to a wider range of materials and scale up its use in the future.
Another technology we’re using is ‘Dope Dye’ – a process where pigments are added to the material before turning it into yarn. No further coloration of the fabric is required. This technology enables us to save water, energy, and chemicals and to improve the resistance of the color of a material.
Finally, we’ve also integrated ‘No Dye’ into our supply base. This completely eliminates the coloration process by using materials in their raw color. No dye products offer an intuitively sustainable aesthetic, and at the same time we reduce the use of chemicals, dyestuffs, water, and energy. As it’s only possible to do one colorway, No Dye can’t be applied to every single product we make, but we will use this approach alongside other low carbon coloration technologies.
Where we are committed to go
Looking ahead to 2023, we’ve set ourselves a number of ambitious goals. In addition to converting more fabric to NTX™ Cooltrans™ and Dope Dye, we are also looking to enable and scale other new and sustainable coloration technologies.
We also plan to scale up this project by almost 400% in terms of the yard volume we’re coloring. This means an increase from 8 million to ~40 million yards. We will share our learnings across the entire company to bring both our Footwear and Accessories & Gear teams on our journey.
Coloration is just one aspect of our business that supports our journey to become a climate neutral company. Keep an eye out for further updates to come.
