新技术通过高效的净化，紧凑的设计和低能消耗而脱颖而出。
随着其新开发的Vacunite技术的介绍，Erema再次展示了其作为创新领导者的作用。奥地利塑料回收机的生产商将其vacurema®瓶对瓶装工艺汇集在一起，并在这项创新中从Polymetrix中获得了新专利的，真空支持的固态多凝结（SSP）。使这种组合如此特别的原因是：所有热过程步骤均在氮气气氛中进行。结果是RPET颗粒在质量上是独特的，并且远远超过了所有食品接触要求。
使用Vacunite Erema扩展了其投资组合，以用于宠物回收解决方案。这项技术是宠物回收将来必须面临的挑战的答案。瓶瓶业的EREMA业务发展经理ChristophWöss总结了这些挑战：“社会对以负责任的方式处理塑料的越来越多的承诺意味着，政治要求和主要饮料品牌的自愿承诺都要求大幅增长最终产品中的回收量。要满足这些要求，一般而言，由于不同的收集系统的质量，还必须回收更多的质量，同时，大品牌对他们的要求变得更加严格产生的回收物。
The focus of the next development of the PET recycling technology was on improving quality even further – which has been accomplished in impressive style. "Our new development brings together the best of what is technically possible," says a convinced Wöss. The process is based on the combination of proven VACUREMA® technology which has been enhanced for this application and the newly patented, vacuum-supported nitrogen SSP from Polymetrix. All thermal process stages take place in nitrogen atmosphere, largely eliminating flake and pellet discoloration and reliably removing additives which could lead to undesired reactions in the melt. Another benefit of VACUNITE: the vacuum support cleans the nitrogen which means it can be returned to the previous processing stage and nitrogen consumption is reduced as a result. Any remaining dust particles are removed from the pellets before filling to avoid preform contamination. "Using vacuum support and nitrogen atmosphere creates rPET recyclates which far exceed all existing food contact requirements, even those of the major beverage brands," emphasises Wöss.
But VACUNITE is special not only because of the exceptional quality of the output material. The recycling technology also stands out through its comparatively compact build, low energy consumption and, compared to vacuum SSP systems, considerably lower maintenance. Depending on machine type, 50 to 60 square metres of floor space is sufficient for the SSP part. The height and substructure also have less impact on the dimensions of the plant building compared to other SSPs. The energy consumption of VACUNITE for the entire production process from the flake to the final pellets amounts to a mere 0.35 kWh per kg. "With VACUNITE we offer our bottle-to-bottle customers a new technology in addition to the existing portfolio which sets new standards at all levels from technical performance to rPET quality," says Manfred Hackl, CEO EREMA Group with conviction and he adds: "There is a great amount of interest. A first customer in Europe has already decided to invest in a VACUNITE recycling plant prior to the official product launch."
