Extrusion International 3-2024

24 Extrusion International 3/2024 NPE2024 with around 11 percent lower spe- cific energy consumption (kWh/ kg) and around 14 percent higher throughput compared to the previ- ous EREMA solution. Since K 2022, EREMA has sold around 20 INTAREMA ® TVEplus ® DuaFil ® Compact systems. The first machines have been delivered and have now entered operation. At RECUPAC S.A., for example, a re - cycling and waste disposal company based in Chile. An application that is currently growing in the USA is the recycling of agricultural film. The producers receive film after it has been used, recycle it, and return it to produc - tion. The demand for technologies for processing heavily printed films is also increasing. Both applications are challenging: agricultural film is typically heavily contaminated with sand, stones and organic matter, and printing inks often enter thematerial being recycled during the melting process. The INTAREMA ® TVEplus ® DuaFil ® Compact provides the high degassing performance required to achieve excellent results using a very efficient process. When recycling ag - ricultural film, for example, EREMA has been able to save 20 degrees Celsius in the melt temperature and 9 percent in energy consumption. At the same time, throughput increased by 11 percent. EREMA launched the ReFresher for producing odor-optimized recy- cled pellets at K 2016. There are now ReFreshers in operation worldwide for film and regrind applications with a total capacity of 1,000,000 tons per year. Combined with the INTAREMA ® TVEplus ® , the anti-odor system opens up completely new ap- plication possibilities for recyclates, such as high-quality end products for the home, automotive and lifestyle sectors, and for processing food-safe polyolefin recycled pellets (HDPE, LDPE and PP). The process has been classified by an American food safety authority as suitable for feeding the recyclate back into the production of food packaging. With its VACUREMA ® and VACUNITE ® systems, EREMA also offers the right solution for the production of food-safe rPET pel- lets. "Think big and safe - that's the message to our bottle-to-bottle re- cycling customers," says Christoph Wöss, Business Development Man - ager for bottle applications at the EREMA Group. In this connection, he points out that customers can now obtain complete systems in- cluding SSP post-treatment directly from EREMA, that can process up to 12,100 pounds (5,500 kilograms) of food-safe rPET pellets per hour. EREMA Group www.erema.com Smart Solutions for Plastics Recycling and Compounding At NPE 2024, Coperion and Her - bold Meckesheim presented a va- riety of advanced components and solutions for plastics recycling and processing at their booth. As a raw material, plastic can make a valuable contribution to en- vironmental protection, the energy revolution and a circular economy. The key is efficient recycling of plas - tics. For this reason, plastics recy - cling is the focus of comprehensive development projects at Coperion and Herbold Meckesheim. The two companies showed the results of these projects at NPE 2024 by pre- senting combined process solutions and technologies for the economi- cal recycling of various plastics while achieving the highest levels of prod- uct quality. On display in the booth was a ZSK 58 Mc18 twin screw ex- truder configured for manufacturing high-quality PET using recycled ma- terials as well as the recently intro- duced ZS-B 70 MEGAfeed side feed- er for lightweight fiber and flakes recycling and a Herbold Meckesheim HV70 plastcompactor. Also on dis- play was a new Schenck Process FPM MechaTron® Flat Bottom (FB) feeder, a high-capacity stainless steel feeder that is designed specifically for handling materials with light and fluffy characteristics such as films and scrap. More equipment for feed- ing, dust collection, pneumatic con - veying, and bulk material handling Thanks to its high intake potential, the recycling of plastic fiber and flake using the ZS-B MEGAfeed side feeder from Coperion becomes much more economical or even possible in the first place (Photo: Coperion, Stuttgart, Germany) The new INTAREMA ® TVEplus ® DuaFil ® Compact is significantly shorter than the previous EREMA double filtration solution.
