Use of waste mineral pigment as fertiliser

Bison code: L.28222

Adidas is one of the leading sportswear brands in the world! For many years now we have been leading the world of sports with innovative products. We continuously seek to advance our products and are therefore exploring new ways of making great products! Especially since sustainability has been part of our strategic priorities we are working to change the industry.

Assignment direction:

It is well known that the dyeing processes in the sportswear industry require radical change because of its negative impact in energy use and chemicals.

As a result, we are working with a novel textile colourant system which applies colour from a pigment embedded micelle structure in water at room temperature. Additionally, the used water is recycled through a sand or silica filter which traps the residual pigment which is not retained on the fabric and which would go down the drain in a conventional dye system, which is one of the main contributors to pollution in the textile colouration industry. We want to investigate the use of this exhausted filter material as a fertiliser, as it contains only natural mineral pigments. This will help show the sustainable benefits of this system compared to conventional dyeing, in addition to the substantial water and energy savings achieved by this process.

When successful, this new dyeing technique could have a huge positive impact on the sportswear industry once it can be scaled up to the next level.

This is a first indication of the direction for the assignment. We are flexible and want to work with the interested students to find the common ground in the final approach for this assignment.

We welcome students open to the world of sportswear manufacturing and who are up for a challenge!
