HolyGrail 2.0 launched: Mondi trials digital watermarking to separate waste for a circular economy

Mondi, a global leader in packaging and paper, has joined forces with AIM, the European Brands Association, and other partners across the value chain to prove the viability of digital watermarking for sorting waste at scale.

The HolyGrail 2.0 initiative has the ambitious goal of assessing whether this pioneering digital technology can enable better sorting and higher-quality recycling rates for packaging in the EU, thereby driving a truly circular economy.

Mondi was a founding member of the original Pioneer Project HolyGrail, facilitated by the Ellen MacArthur foundation. Now over 85 partners across the value chain are reportedly working together to refine and commercialize this concept, with Mondi continuing its active role in trialing the innovative technology.

Postage stamp sized watermarks on packaging, which are not visible to the naked eye, make it possible to effectively sort the material into specific waste streams. With this new technology, it could become possible to separate materials more accurately and generate new waste streams, which then can be recycled with enhanced recycling technologies.

“At Mondi, we believe packaging should be sustainable by design and we see the need to improve the sorting and separation of packaging waste as part of a circular economy,” said Graeme Smith, head of product sustainability, flexible packaging and engineered materials, Mondi. “Digital watermarks have the potential to make this a reality. Improved recycling will increase the value of packaging waste, driving higher collection rates and making it a valuable commercial resource for the future.”

As HolyGrail 2.0 progresses, Mondi is well positioned to contribute to its success by validating digital watermarks with partners along the value chain. Mondi will reportedly conduct full-scale industrial trials with key customers in the near future.
