A developer of recycling processes for composite packaging comprised of various materials, Saperatec’s prototype is produced in collaboration with two prominent partners: Germany-based packaging film supplier Wentus – whose mono-polyethylene flexible packaging design allows for easy recyclability – and adhesives, sealants, and functional coatings provider Henkel, which supplies the package’s 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® Pure R, the marketing design recently received 18 of 20 points from Germany-based recycling alliance Interseroh.
The prototype is made possible by a promising new technology: Saperatec’s 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‘s optimized adhesive for recyclability. Overall, the packaging will contain at least 35% PCR rLDPE – in line with the proposed recommendations for the EU Directive regarding non-food packaging.
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.
