31 Mar 2022 --- The HolyGrail 2.0 digital watermarks initiative has successfully validated its prototype detection unit from semi-industrial testing mimicking real-life conditions. The results indicate that the digital watermark technology can achieve more granular sorting of packaging waste at scale, such as developing separate food and other new post-consumer recycled (PCR) streams, like cosmetic or detergent applications. The initiative’s leaders AIM – European Brands Association and Alliance to End Plastic Waste describe the validation as a “significant milestone,” opening up new recycling streams by overcoming the limitations of current near-infrared (NIR) sorting technologies.
