MACHINERY | RECYCLING AND GRANULATORS
Hosokawa Alpine’s Polyplex PPC 50/120 combines a shredder and granulator in a single machine
had the necessary mechanical properties – and would operate well in its tools and strapping machines. Thanks to the new material, Signode has launched
a new range of recycled products with properties similar to those made with virgin raw materials. This has helped both companies meet the sustainability commitments of many industrial sectors.
Film improvement Colines says that the latest version of its Pure technology is a “new benchmark in trims re-feed- ing for cast PP film”. The company says that the technique helps to
improve the optics and mechanical performance of recycled film. For instance, it says the old technique blended
centres, to create recycled resin for consumer packaging and other applications. The process will convert HDPE and PP into products for use in both food-grade and non-food-grade applications. “Companies today are setting aggressive
recycled content goals, and we have a unique opportunity to meet the demand for high-quality recycled plastics through the creation of Blue Polymers” said Jon Vander Ark, president and CEO of Republic Services. “Ravago’s leadership in plastics recycling and compounding makes them a natural partner.” Four Blue Polymers facilities are scheduled to open over the next four years, beginning in late 2024. In total, they are expected to produce 300 million pounds (around 136,000 tonnes) of recycled plastics per year. Products will include custom-blended and compounded materials.
Right: Repsol and Signode’s new strapping material uses 30% mechani- cally recycled PP
Strapping uses recyclate Repsol and Signode have developed a polypro- pylene (PP) compound specific for high-tenacity strapping, that incorporates 30% mechanically recycled post-consumer plastic waste. Repsol Reciclex RXP33AAA, which is certified under the Recyclass scheme, claims to reduce carbon footprint by 9%. Incorporating recycled material into the formulation has been a challenge due to the high consistency and toughness required for the application. Based on Signode’s requirements,
Repsol selected specific recycled material flows – in collaboration with Acteco – and tested numerous formulations. Signode performed all the performance tests to confirm that the material’s final formulation

fluff into a thick core layer, while the new process separates fluff in a thin core layer. This has shown impressive results, with better optics than stand- ards CPP film, and better elongation and break and load at break, with improved web handling on post-conversion units. “The technology performs in alignment with the
extrusion process, to give a proper separation of the in-line trims from the virgin granules,” said the company.
It also allows the use of additional scraps – of the same type – to be added to the production stream, further increasing the amount of recycled material that can be used in film production. “The technology has been validated by several customers, who have used it in their industrial flexible packaging film production over the last three years,” said Colines.
Battery recycling Hosokawa Alpine has developed a range of solutions to recycle cathode and anode film scrap during the production of lithium-ion batteries.
