REUSE PILOT relies on the GS1 GRAI standard identifier to identify containers.

What is a GRAI?

As explained in this document, the GRAI, Global Returnable Asset Identifier, is a unique code to identify an asset throughout its life cycle.

Its structure is as follows:

  • leading 0
  • the GRAI root composed of 12 digits, based on your GS1 company prefix, representing the asset type
  • the GS1 check digit (which can be computed using the GS1 check digit calculator)
  • a serial number of up to 16 alphanumeric characters

How does REUSE PILOT use GRAI for identifying containers?

The GRAI is then used to build a URL following the GS1 Digital Link standard.

The URL structure looks like https://my.domain/8003/GRAI where

  • https://my.domain/ is to be replaced with your domain name
  • 8003 is the GS1 Application Identifier (tag) indicating a GRAI
  • GRAI is the container GRAI

The URL is then encoded into a QR code.

Finally, a label with the GRAI QR code must be fixed to the container.

Prerequisites to use REUSE PILOT

For managing containers using REUSE PILOT, each container must be idenfiable with a QR code encoding the GRAI-based GS1 Digital Link.

Thus, you should:

  • have a GS1 company prefix
  • manage the set of GRAI
  • produce the QR code for each GRAI
  • print the corresponding label
  • fix it to the container
