Saperatec, a developer of recycling processes for composite packaging comprised of various materials, will debut a fully circular flexible packaging prototype based on its multi-layer delamination technique at the K Fair Trade Show, October 19-26 in D\u00fcsseldorf. At Hall 9, Stand D17 \u2013 a booth shared with prominent machinery manufacturer Pla.to GmbH \u2013 Saperatec engineers will showcase and discuss a detergent package which, at 35% post-consumer recycled content (PCR), meets goals proposed for the pending EU Directive on Packaging & Packaging Waste.<\/p>\n
Among the first consumer flexible packaging materials made from post-consumer packaging waste, the prototype is produced in collaboration with two prominent partners: Germany-based packaging film supplier Wentus \u2013 whose mono-polyethylene flexible packaging design allows for easy recyclability \u2013 and adhesives, sealants and functional coatings provider Henkel, which supplies the package\u2019s recycling-optimized adhesive. Notably, Henkel also made a significant investment in Saperatec in 2019, which has helped make the forthcoming plant a reality. Currently marketed by Wentus as Wentoplex\u00ae Pure R, the marketing design recently received 18 of 20 points from Germany-based recycling alliance Interseroh. <\/p>\n
The prototype is made possible by a promising new technology: Saperatec\u2019s extended mechanical recycling process for thin-layer composite materials, which results in virgin-similar recyclates. A two-layer design made entirely from polyethylene (PE), its inner sealing layer comprises more than 50% PCR rLDPE from beverage carton waste. Its outer layer is printed with less than 50% surface coverage, and laminated with Henkel\u2018s optimized adhesive for recyclability. Overall, the packaging will contain at least 35% PCR rLDPE \u2013 in line with the proposed recommendations for the EU Directive regarding non-food packaging. <\/p>\n
With the technology extensively tested in materials science labs and near-industrial pilot environments, Saperatec is currently building its first recycling plant for composite packaging in Dessau, Germany. In 2023, the facility will commence commercial operations with an initial goal of processing about 18,000 tons of packaging waste per year.<\/p>\n
Saperatec\u2019s composite packaging recycling brings the potential to separate and reintegrate a wide variety of substrates into the packaging stream. Initially, Saperatec will focus on composite flexible packaging materials and tube packaging with aluminum foil barriers, as well as plastics and aluminum from beverage cartons. Beyond that, Saperatec\u2018s technology opens the door for future recyclability solutions in a wide range of composite packaging.<\/p>\n
Importantly, Saperatec\u2019s recycling process is sustainability-minded. The hot-wash separation fluids utilized are water-based and solvent-free, and are reused more than 30 times in the process. Any and all materials employed during packaging recycling are listed for food contact materials without specific migration limit, per European regulations.<\/p>\n
