41 Extrusion Asia Edition 2/2021 ➠ SCHÜTZ GmbH & Co. KGaA Schützstraße 12, 56242 Selters, Germany www.schuetz.net 始终观察带“环保层”中型散货容器中的填充水平。 舒驰还使 用多层挤出方式生产出的桶，将最大的安全性与最大的再生 塑料含量相结合。 220升 的 F1 闭口桶和 30升 至 220升的 S- DS1 开口桶也作为“环保层”型号使用三层挤出中空吹塑工艺 生产，中间层为回收的 HDPE。这里的再生料成分占桶身的 40%，整个产品系列都通过了危险品认证。 通过试点项目在欧洲市场推出 欧盟通过《欧洲绿色协议》和《循环经济行动计划》， 明确了资源节约型经济增长的目标和框架条件。新的“环保层” 产品已经满足了在包装中使用回收材料的未来法律要求。为 了确保使用再生塑料材料的中型散货容器和桶的持续供应， 舒驰强调了客户和旧工业包装回收者积极合作的重要性。只 有在舒驰预订服务（舒驰用于翻新和回收工业包装的全球系 统）有足够的回收材料供应时，才能保证相应的供应安全。 因此，向市场推出绿色层的产品需要与客户密切配合，最初 仅限于欧洲，在那里成功启动了试点项目。得益于舒驰的全 球生产网络以及最先进的多层挤出吹塑设备，未来扩展到其 他地区是可能的。 T he IBCs, which are developed in-house and manufactured around the world, owe their leading global position to the highly efficient and environmentally friendly combination of reusable and disposable systems. In the new Schütz Green Lay- er versions, the eco-balance of both types of packaging has been taken to a new level. In the multi-layer extrusion process, the IBC inner bottles and drum bodies are produced with 40 per cent high-quality plastic recyclate. This material is generat- ed by Schütz through its worldwide collection and recondition- ing programme. Another key feature is that the IBCs of the Green Layer series also have UN approval. Ecological Packaging as a comprehensive concept Multiple use and recycling, the two factors that sit at the heart of the circular economy, have always been a core concept of Schütz IBCs. The entire life cycle of the packaging is geared to- wards ensuring maximum environmental friendliness. During reconditioning as part of the Schütz Ticket Service, the inner bottles of collected IBCs are removed from the steel grid and treated in a complex recycling process during which they are ground, cleaned and finally regranulated. Special degassing ex- truders ensure a low-odour, homogeneous quality. The compa- ny uses the HDPE recyclate obtained in a closed cycle: 100 per cent flows back into the internal production of plastic packag- ing components, including corner protectors and plastic pallets. This is why Schütz IBCs have always had an exceptionally high proportion of recycled material. Depending on the type of pal- let, the proportion is between 36 and 55 per cent of the plastic in the entire IBC. Additional CO 2 saving: more than eight kilograms per IBC With the new Green Layer IBCs, Schütz has increased this pro- portion even further, taking resource preservation to a new level. For these containers in particular, high-quality recycled material is also used for the production of the inner bottle. The IBC container in the innovative Green Layer design contains 40 per cent recycled material alone. This corresponds to an addi- tional CO 2 saving of at least eight kilograms per IBC. The recy- cled HDPE is extruded only into the middle layer of the contain- er. The inner and outer layers are made of virgin HDPE material. This way, Schütz ensures that both the filling product and the environment only come into direct contact with virgin material, making a significant contribution to protecting the quality of the filling product. Equipped with a full-plastic pallet, the total content of recycled plastic in this particular IBC model is as high as 73 per cent. Sustainable IBCs and PE drums with UN approvals With its ecological packaging and low CO 2 footprint, Schütz supports its customers in achieving their sustainability goals. And there is another benefit: the new Schütz IBCs have UN ap- proval and are therefore also suitable for a wide range of dan- gerous goods applications. The new containers also impress with their uniform appearance. The outer layer is completely black, thus avoiding colour variations that often occur when re- cycled material is used in IBC inner bottles. Transparent view stripes enable the user to monitor the filling level in Green Lay- er IBCs at all times. Schütz also uses multi-layer extrusion for the production of drums, combining maximum safety with a maximum content of recycled plastic. The F1 tight-head drum in 220l and the S-DS1 open-head drums in sizes 30l to 220l are also produced as Green Layer models using the three-layer ex- trusion blow-moulding process with recycled HDPE in the middle layer. The recycled content here accounts for 40 per cent of the drum body and the entire product range has dan- gerous goods approvals. Market launch in Europe with pilot projects With the European Green Deal and the Action Plan for the Cir- cular Economy, the European Union has defined the goals and framework conditions for resource-saving economic growth. The future legal requirements for the use of recyclate in pack- aging are already met by the new Green Layer products. In ord- er to ensure a constant supply of IBCs and drums with recycled plastic material, Schütz emphasises how important it is for cus- tomers and returners of used industrial packaging to actively cooperate. A corresponding supply security can only be gua- ranteed, if there is a sufficient supply of recyclate from the Schütz Ticket Service, the global system for the reconditioning and recycling of industrial packaging by Schütz. The market launch of the Green Layer products therefore requires close coordination with customers and is initially limited to Europe, where pilot projects have been successfully launched. Future expansion into other regions is possible and intended thanks to the global production network of Schütz with state-of-the-art multilayer extrusion blow moulding equipment.
