Pilot project about DPP presented at DCongress

March 13 2024

Digital product passports (DPP) will become mandatory for textiles in just a few years. They are already being implemented on garments at Kappahl and Marimekko as part of a pilot project within Trace4Value. On March 7th, they were presented at DCongress in Göteborg, arranged by Swedish Commerce.

Sandra Roos, Kappahl, and Linn Lindfred, Trustrace/Circularista gave the audience an insight into how a digital product passport works for the consumer, by scanning a QR code on a garment. The digital product passport was displayed on a large screen.

-This set-up provides possibilities to share and add unique product information into the DPP throughout the product life. So when you just saw Sandra scan the QR code, the unique ID through a GS1 digital link sends a request to a resolver, which identifies in what data source the data associated to that specific product resides. The data is validated then fetched from the different data sources via API:s, and then it shows up on your screen. The data can be stored in different places, in a decentralised data storage, in this pilot it is stored in two different platforms.

Sandra Roos emphasized that the DPP is beneficial not only for customers but also for companies.

-Kappahl and other brands can benefit because the DPP will provide relevant information to the consumers in a standardized way. The information will be validated and we will have a lot more information about the sustainability claims we make, to see if they are true or false. It will be easier to distinguish between good and bad products. It will also be easier for authorities to do this legal supervision to see if the claims are correct. This is important if we want to reach this transition to a sustainable society, said Sandra Roos.
