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

-AIM, the European Brands Association, has launched HolyGrail 2.0 with Mondi and other partners across the value chain to prove the viability of digital watermarking for sorting waste at scale.
-Digital watermarks have the potential to revolutionise the way we sort and recycle waste, increasing the commercial value of waste so that it can be reused again as a resource.
-Mondi was a founding member of the Pioneer Project HolyGrail and continues to play an active role to validate the technology. This includes running trials with partners across the value chain.

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 working together to refine and commercialise this concept, with Mondi continuing its active role in trialling 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. Conventional sensor technologies (e.g. near infrared spectroscopy) are not able to reliably identify multi-material packaging, so they can end up as contaminants when recycling mono-materials. With this new technology, it becomes possible to separate materials more accurately and generate new waste streams, which then can be recycled with enhanced recycling technologies.These digital watermarks also provide other opportunities. For example, consumers can use a smartphone app to find details about the packaging and how to recycle it, and brand owners can add product details as well.

Mactac Announces OODLES Media Meets Newest Elevator Wrap Compliance Requirements

Mactac® Distributor Products announces its OODLES multi-print wall media has earned UL 10b and 10c certification, meeting the latest compliance requirements for out-facing elevator door applications. Compliance is necessary for any elevator wraps being used in the healthcare industry, such as in hospitals and other care facilities. Earlier this year, The Joint Commission, a leading accreditation and regulating body in healthcare, changed the fire rating for elevator doors, requiring the UL 10b and 10c certification to apply graphics materials on outside-facing doors. Compliance is also recommended for outdoor elevator graphics in schools, universities, hotels, and other similar buildings and facilities. “Customers can now confidently apply Mactac OODLES media to elevator doors within these settings and have peace of mind knowing that they are in compliance with the required safety standards,” says Amanda Smith, Product Manager, Mactac Distributor Products. “The certification adds to the versatility OODLES media already delivers.”
