September 29, 2023 (press release) –

The ALDI SOUTH Group and ALDI Nord are taking part in the 3rd phase of the HolyGrail 2.0 initiative, a program driven by AIM-European Brands Associations and powered by the Alliance to End Plastic Waste. Adding watermark technology to packaging will help to improve sorting in waste facilities and boost recycling for a circular economy.

Digital transformation and collaboration are key to achieving ALDI’s International Packaging Goals. ALDI recognises the value of investigating and trialing innovative solutions that bring the industry closer to a transition towards a circular economy.

In preparation for the testing phase of the HolyGrail 2.0 initiative, ALDI SOUTH and ALDI Nord have partnered with Digimarc and WIPAK to print invisible codes on packaging to improve sorting of materials. Our suppliers, in collaboration with packaging converter GREINER, have ensured that 18 different MILSANI kefir and yoghurt flavours have been digitally enhanced with watermark technology. These products can already be found in ALDI stores across the German market.

The technology has been added to the surface of packaging to test an intelligent way to sort the materials, enabling high-quality recycling outcomes. The packaging will be detected and decoded by a high-resolution camera on the sorting line at the recycling facility, accurately separating the different materials to their corresponding streams.

ALDI hopes to contribute to this phase of the HolyGrail 2.0 initiative by testing the technical and economic viability of watermark technologies to improve material sorting. This trial will enable further investigation into the potential of watermark technologies as a driver of sustainable packaging.
