Newcycling^® is an innovative, solvent-based plastic recycling process developed by APK AG in Merseburg/Germany to make high-quality recyclates out of packaging waste. For this process APK is relying on the high-performance ZSK extruder technology and technical process expertise from Coperion. Using the Newcycling^® process, multi-polymer and multi-layer plastic packaging, that previously could not be recycled, can now be separated and processed into homogeneous regrind using ZSK twin screw extruders. In contrast to chemical recycling, the polymer in this process remains unchanged and does not require energy- and cost-intensive re-polymerization. Newcycling^®, therefore, is highly efficient from a cost and from an environmental perspective.

Thanks to the innovative, solvent-based Newcycling^® treatment, as well as the excellent devolatilization performance and gentle material handling in the ZSK extruder, the quality of the recyclates is close to that of virgin product.

Newcycling^® – An Economical and Ecological Sensible Recycling Process

The necessity of a circular plastic economy has never been greater than today. With its innovative Newcycling^® process, APK is laying an important cornerstone for achieving the goal of greater sustainability and higher recycling rates in the plastics industry.

This one-of-a-kind physical and solvent-based process enables clean and single-origin polyamide (PA) and polyethylene (PE) pellets with virgin-near material character to be extracted from complex PA/PE multi-layer films. These recyclates can be reused in high-quality products up to the original application. Downcycling can thus be reduced and closed-loop recycling becomes possible.

In Newcycling^® at APK’s Merseburg location, PA/PE multi-layer film is first mechanically pre-treated, undergoing among other things shredding and classification. Next, the PE layer is dissolved and liquefied in a solvent bath, leading to separation of the polymers and polymer layers. The undissolved PA is then separated from the dissolved PE using conventional solid-liquid separation technology and the polymers are further processed in separate material streams.

The PA is introduced into a Coperion ZSK twin screw extruder where it passes through various process sections and is processed into a high-quality PA melt using very high dispersion performance and intensive devolatilization. Finally, it is pelletized into first-class PA recyclates.

Following pre-evaporation, the PE is likewise introduced into a ZSK twin screw extruder together with the solvent. There, intensive devolatilization of the liquid takes place, precisely calibrated for this application to produce first-class results even when PE/solvent ratios fluctuate. The solvent is completely volatilized and added back into the Newcycling^® process in a closed loop. PE remains in the form of a homogeneous, high-quality melt that is then pelletized. The PE recyclate possesses quality similar to that of virgin product. 

PE recyclate manufactured using APK’s Newcycling^® technology and marketed under the brand name Mersalen^®, as well as PA recyclate sold under the brand name Mersamid^®, stand out for their high product quality and substantial reductions in emissions. Newcycling^® recyclates exhibit on average 66% fewer emissions than virgin material of a given plastic. The recyclates’ very high degree of purity has been confirmed by numerous expert reports and is suited for a wide range of applications such as cosmetics packaging.
