Due to the extraordi- nary cleaning performance, the processed PET can easily be re- cycled multiple times and thus saves further valuable resources compared to virgin PET or energy than other packaging materi- als such as glass. Plant expansion: new space for the next generation of recycling machines In order to continue to increase plastics recycling rates world- wide under the slogan "Working for a better Future" and to be able to offer ever more efficient machines for its customers, more than 10 million EUR was invested in the expansion of the Feldkirchen site. Near the company's headquarters in the Feld- kirchen industrial park, a new, energy-efficient operating facility was built offering over 10,000 m² of space for the next genera- tion of recycling machines. "Just as with the machines produced by NGR, the use of renewable energies and maximum energy efficiency are also at the forefront of the site expansion," ex- plains Erich Fürst, COO of the company. "For energy efficiency, we use both groundwater heat and the heat output of our ma- chines to heat or cool the premises. As a result, we don't need a secondary energy source." Through intelligent planning and a sustainable energy supply concept, the company thus saves 288 tons of CO 2 annually. The first building, which was con- structed 15 years ago, is also being redesigned and equipped with sustainable technology. In the process, a completely new plastics laboratory was set up and extensively equipped with the measuring and analysis techniques needed to compare and eva- luate the plastic qualities of the starting and end products. In a demonstration center set up especially for this purpose, custom- ers can fully evaluate the equipment and convince themselves of the quality of their newly obtained raw materials. The NXT:GRAN sets new standards – The all-in-one solution for efficient recycling With this new generation of machines, the name says it all. The NXT:GRAN enables the plastics processing industry to achieve true zero-waste production. It guarantees full value retention of the material and, thanks to newly developed technology, reduc- es labor and energy requirements to an absolute minimum. With its mission to simplify the recycling of plastics more and more, the particularly maintenance-friendly NXT:GRAN also relies on so-called "ONE-STEP technology" which, in contrast to conven- tional recycling systems, allows plastic waste to be reprocessed in a single highly efficient step. Material shredding, extrusion and granulation can be handled by a single system, and up- stream shredding processes and conveying equipment are eli- minated, saving not only space but above all energy. This technology, patented under the name shredder-feeder-extruder combination, also reduces problematic dust formation and has revolutionized plastics recycling. In addition to the increased cut- ting capacity in the shredder, the NXT:GRAN provides additional power through an optimized material feed to the extruder, which is positively arranged to the extruder screw. This unique design achieves a significant increase in output across the entire material spectrum. The extra high-quality recyclate recovered can be fed directly into the manufacture of a wide variety of new end products, thus saving raw materials, reducing the CO 2 foot- print and optimizing manufacturing processes. However, NGR has identified potential for improvement not only in post-industrial materials, but also in the field of PET reproces- sing and is tackling used PET bottles with new technologies. Next Generation also in PET Improvement – The Future of PET Recycling Since PET materials such as empty bottles, films, or textile fibers are also valuable raw materials for the manufacture of new products, the specialists from Feldkirchen offer a revolutionary solution. With the Liquid State Polycondensation (LSP) process, a completely new possibility has been developed under the trade name P:REACT for reprocessing PET waste into food-grade ma- terial making use of an extremely efficient process. While conventional PET reprocessing methods change the ma- terial properties in the solid phase, taking many hours, the de- contamination of the material in the LSP process takes only a few minutes. In this innovative process from NGR, PET is repro- cessed in the liquid phase, which guarantees simultaneous up- grading of the plastic and recycling to the highest standards of brand owners. With melt phase reprocessing, the company ex- ceeds regulatory requirements towards food grade (upcycling) and has created a unique selling point in the global market. Im- purities and hazardous substances stored in PET, such as ben- zenes, are almost completely removed, taking PET recycling to a new dimension. The material properties, which are chemically degraded during reprocessing, can be completely restored, and even improved, by the LSP process. As a result, the processor re- ceives a recycled material stream of the same high quality as is generally expected from the original granulate (virgin material). Brand owner tests confirm that, if required, the material pro- perties after the LSP process are even higher quality than those of the input material. Food grade approvals by the FDA (Food and Drug Administration - USA) and the EFSA (European Food Safety Authority) certify that the LSP process produces the most 58 回收再生 Extrusion Asia Edition 1/2023
