Right: Combining Erema’s Intarema TVEplus and ReFresher module recycles polyolefin for food use
prolonged operational life, reduced maintenance, and enhanced performance. Additionally, customisable settings enable
operators to adjust parameters such as speed, cutting chamber size, and screen configurations to achieve optimal results with different materials.
Packaging benefit Erema will highlight a number of film recycling technologies at Fakuma in October. It says the EU’s PPWR (Packaging and Packaging
hopper granulator and a type RS 30090-E infeed granulator.” The RS 45090 is used by Lechner as a central
granulation station. It has a cutting width of 900mm and processes round, square, and heavily ribbed production scrap with an hourly throughput of up to 900kg. “As the ideal addition to its RS 45090, Getecha
also provides a side bypass hopper to feed through long parts. This saves us having to pur- chase another granulator,” said Lechner. The grinding chamber features a triple-blade
rotor with oscillating weight and additional third stator blade. This robust configuration improves the processing of heavily ribbed components and prevents remnants from dropping too deep, significantly increasing overall efficiency of the granulation process. The inside of the hopper and the granulator housing are both equipped with hardened wear protection plates, which can be replaced when worn. Another important aspect is the integration of a new hopper granulator into the existing disposal/cycle processes at the customer’s factory. To facilitate the use of an independent and self-cleaning vacuum conveyor station, Getecha engineers modified the suction tub of the RS 45090 and equipped it with a fill level sensor. Lechner is using vacuum moulds to process PET and compound films with thicknesses up to 2.5mm for large-scale production parts. To dispose of scrap web and faulty parts, the company opted for an infeed granulator designed and sized to process scrap material and hybrid films together with cardboard packaging. The hourly throughput rate is up to 670kg. Many of the latest granulators to hit the market
feature improved cutting technologies, allowing for greater durability and precision in the size and shape of granules produced. High-performance materials and advanced geometries contribute to

Waste Regulation) demands a significant increase in the proportion of recyclates used in packaging products by 2030. There is also the need to use more recycled materials in areas like the automo- tive industry. “We see new legal requirements such as the PPWR as an opportunity to demonstrate our expertise,” said Markus Huber-Lindinger, managing director at Erema. “The European recycling industry has the know-how to meet these requirements, which gives Europe a significant competitive advantage.”
It says the combination of its Intarema TVEplus
and its ReFresher module allows recycled polyole- fin pellets from defined input streams to be reused in food packaging in proportions of up to 100%. By decontaminating the plastic and removing unwant- ed odours, it opens up other applications for recycled pellets, such as automotive and personal care products. As demand for recyclate increases, so does the
need to raise capacities using larger machines. For recycling PET, Erema supplies systems with throughputs up to 6 tonnes/hour. It has also built machines for recycling polyolefins with a through- put of over 4 tonnes/hour. “This wide selection of technologies is necessary
for efficient recycling, because the method must be matched to the polymer, degree of contamination, input material and the application that the recycled pellets will be used for,” he added.
