Precise, autonomous, mechatronic: PAM calibrates coextrusion adapters and dies automatically for best comfort, quality and productivity

Precise, autonomous, mechatronic: PAM calibrates coextrusion adapters and dies automatically for best comfort, quality and productivity

At K 2022, Reifenhäuser is presenting its new PAM automation option for coextrusion adapters and slot dies in flat film and sheet production, and for extrusion coating for the first time worldwide. The high level of automation makes the machine operator's work significantly easier, thus increasing line productivity and film quality. Energy consumption is also reduced, as manual adjustment bolts replace the conventional thermal expansion bolts.

Up to now, when starting up the extrusion line or changing products, many individual operations have been necessary until the coextrusion adapter and die are set correctly. Manufacturers lose time and money as a result. For this reason, Reifenhäuser has now developed an automation option that relieves line operators of this work: PAM (precise, autonomous, mechatronic).

With the PAM option, coextrusion adapter and die can be adjusted automatically and mechatronically - precisely controlled via the line's operating panel. This is significantly faster than conventional control by hand or expansion bolt automation, and enables faster start-up of production, higher output and improved overall equipment efficiency (OEE). Scrap and material usage are significantly reduced. In addition, recipes that have been set once can be stored and recalled at any time. They can therefore be reproduced exactly - even by inexperienced line operators.

The stored setting parameters not only facilitate future production, but also the tracing of individual products and provide proof to customers. Another advantage of contactless calibration with PAM is that the line operator no longer has to work on the hot components, which increases work safety and prevents damage to the machine. PAM is optionally available for new Reifenhäuser "Pro" type coextrusion adapters and for various dies, but can also be retrofitted to existing lines regardless of the manufacturer.



PAM for coextrusion adapters
The Reifenhäuser coextrusion adaptor Pro is the only coextrusion system on the market that allows profiling of the individual layers while the line is running. Unlike conventional solutions, elements located in the adapter do not have to be removed, processed and reinstalled in a time-consuming process. Instead, profilers can be flexibly controlled individually or together during operation via a central adjustment.

"The PAM option goes one step further," explains Hanna Dornebusch, application engineer at Reifenhäuser Cast Sheet Coating. "PAM automates the setting of the layer distribution and simplifies adjustments and optimizations through integrated recipe management. This is especially worthwhile for manufacturers of films with many layers and many product changes."

While with simple 3-layer compounds the coextrusion adapter is adjusted in a few steps, up to 70 profilers have to be adjusted for barrier compounds with 11 layers, for example. Compared to manual adjustment by a machine operator, automation saves about half an hour of changeover time - depending on the number of profilers to be adjusted.

PAM for dies
From single actuators to translator technology, PAM is the logical innovation from decades of Reifenhäuser development in the field of die control. With two manual adjustment bolts, the system combines energy efficiency with low setup and operating complexity of the control system.

The PAM option is suitable for dies in flat film and sheet production as well as for extrusion coating. The system enables autonomous and mechatronic adjustment and control of the flex lip via the line control system. Depending on the die design, autonomous adjustment of the restriction bar, width adjustment and lip opening via adjustment of the lower die lip is also possible.

"With the PAM option, we now offer our customers a highly convenient solution with a fast return on investment," explains Tim Bänsch, die product manager at Reifenhäuser Extrusion Systems. "Compared to dies that are adjusted with thermal expansion bolts, changeover time and energy consumption are significantly reduced."

For example, a width changeover with PAM in a cast application with internal width adjustment is 78 percent faster than with a conventional system. In addition, PAM saves energy because no thermal expansion bolts need to be permanently powered. For example, switching from thermal expansion bolts to PAM for a 3,000-mm-wide die saves of about 130,500 kilowatt hours per year.

PAM is a joint development of the "Reifenhäuser Extrusion Systems" business unit, which specializes in extrusion components, and the "Reifenhäuser Cast Sheet Coating" business unit. The PAM option can be selected independently for coextrusion adapters and dies - but in combination, the automated components unleash their full strength.

"We are one of the few machine builders in the market that manufacture everything ourselves - extruder, coextrusion adapter and die," says Tim Bänsch. "Due to this hot part competence within the Reifenhäuser Group, we know the process technology interfaces very well and can design everything accordingly to each other - PAM takes it all to a new level."

Reifenhäuser Blown Film provides technical solution to one of the biggest challenges in the processing of recyclate

Reifenhäuser Blown Film provides technical solution to one of the biggest challenges in the processing of recyclate

The line manufacturer Reifenhäuser Blown Film presents at K 2022 a technology that makes blown film producers independent of highly fluctuating recyclate qualities and ensures a stable production process - even when processing low-quality input material: EVO Fusion upgrades recyclate qualities.

With EVO Fusion, blown film producers also process previously unusable, lowest-quality recyclates into high-performance blown films for simple end-uses, such as trash bags or mailing bags. Until now, such low-grade recyclates could only be used for simple and thick-walled injection-molded products. In addition, producers can make higher-quality film from recyclates that could also be processed in the past.

Eugen Friedel, Director Sales at Reifenhäuser Blown Film, explains, "In order to drive the circular economy, recyclate rates in blown film products must increase and classic downcycling must be limited. With EVO Fusion, we offer a unique process that enables customers to process even low recyclate grades easily and economically into high-performance products and increase the recyclate content. In this way, processors open up new fields of application for recycled products."

The EVO Fusion process relies on direct extrusion, which eliminates the need for energy- and cost-intensive regranulation of the raw material. This means that fluff (film shreds) and all types of production waste and PCR material can also be processed directly.

This is made possible by the twin-screw technology, which homogenizes the melt better and thus ensures a stable process. In addition, processors can degas the system very easily and effectively, removing unwanted components in the recyclate.

For processing better quality regranulates, Reifenhäuser recommends the EVO Ultra single-screw extruder. Thanks to optimized barrier as well as shear and mixing parts, this extruder processes recycled material as reliably and naturally as other raw materials - the ideal prerequisite for success in the growing market for products with a high recycled content.

Reifenhäuser provides trade fair visitors at K 2022 with fully recyclable FFP2 masks free of charge

Reifenhäuser provides trade fair visitors at K 2022 with fully recyclable FFP2 masks free of charge

At K, the world's largest plastics trade show, thousands of visitors come together to learn about the latest innovations - especially on sustainable plastics products. This year, visitors will already encounter one such innovation at the trade show entrance: fully recyclable and climate-friendly FFP2 masks. Reifenhäuser provides the masks for protection against respiratory infections to trade fair visitors free of charge at all entrances.

FFP2 masks have so far caused major problems when it comes to recycling: they are usually made of many different materials, for example functional layers of polypropylene and textile, nose clips made of metal, ear loops made of polyester. As a result, resources are lost to the circular economy, and the carbon footprint is devastating - especially due to the enormous increase in mask consumption caused by the Corona pandemic.

The mask for K 2022, on the other hand, consists of 99.7 percent polypropylene. It is therefore considered a mono-material product and is 100 percent recyclable. In concrete terms, this means that the nose clip is made of 100 percent polypropylene instead of wire. The same applies to the support layer, which is otherwise made of so-called Hot Air Cotton. The ear loops - usually made of PES (75 percent) and elastane (25 percent) - are 85 percent PP and 15 percent Cradle2Cradle certified elastane. The total elastane weight per mask is thus only 0.3 percent. The individual packaging for the FFP2 masks is also made of 100 percent PP and can be recycled together with the masks. The mask was produced by the Grabher Group, a specialist in technical textiles, using a Reifenhäuser meltblown line.


Reducing the carbon footprint
The sustainable FFP2 masks are not only fully recyclable, but also cause significantly less CO2 emissions during their production than conventional protective masks. The entire production process is designed to keep the carbon footprint as low as possible: the masks are manufactured entirely in the EU, avoiding long transport routes. CO2-neutral PP resins based on Borealis Bornewables™, a renewable premium raw material that offers the same material performance as virgin polyolefin but is independent of fossil raw materials, are used for production. The nonwoven is produced with green power on energy-efficient Reifenhäuser line technology. Added up, a recyclable FFP2 mask thus has a CO2 footprint of only 8 grams of CO2 equivalents - that is one tenth of a conventional mask produced in Asia.

Reifenhäuser extrusion lines provide carbon footprint calculation for more sustainable and economical production

Reifenhäuser extrusion lines provide carbon footprint calculation for more sustainable and economical production

Reifenhäuser is presenting a new digital solution for carbon footprint calculation at K 2022: the Carbon Footprint Dashboard. This enables film and nonwovens producers to see how the carbon footprint changes in ongoing production and identify how they can reduce their emissions. The dashboard thus contributes both to climate protection and to economic success, because a CO2 reduction is usually also accompanied by savings in energy and raw materials. The prerequisite for the carbon footprint calculation is the standard version of Reifenhäuser's digital solution ExtrusionOS & c.Hub Middleware and the availability of the required data.

Dr. Tim Pohl, Director Sustainability and Business Development at the Reifenhäuser Group, explains: "The Carbon Footprint Dashboard shows the different emission sources over the production period. In the basic version, assumptions are made about the carbon footprint of the raw materials used and the calculation is based on the energy mix of Europe, for example. This is sufficient to determine initial potential for carbon footprint reduction. If more precise information is required, we can customize the calculation according to local conditions. Such a calculation becomes exciting when in-house recycled material is used."

Carbon footprint calculation for manufacturing companies is quite complex and starts with the different methods of calculation - at the company level, but also at the product level. The corporate carbon footprint (CCF) balances the CO2 footprint for the entire company - from energy procurement to production to the vehicle fleet. The product carbon footprint (PCF) records all CO2 emissions that occur along the life cycle of a product, i.e. from raw materials to production and use to disposal.

Manufacturers of films and nonwovens can therefore approach the topic of calculation "bottom-down" via a corporate carbon footprint, or they can do it "bottom-up" via a product carbon footprint for each of their products. The latter is ideal if a broad product portfolio with different raw materials and recycled content is processed. For this purpose, a customer-specific carbon footprint dashboard can be created in Reifenhäuser's ExtrusionOS software solution.

From an economic point of view, the carbon footprint calculation is worthwhile in any case: Producers can show the carbon footprint to third parties and thus certify a particularly sustainable product series, for example. This opens up new sales markets and increases economic success. In addition, the savings in energy and raw materials pay off, especially in view of the current high purchase prices.


Carbon footprint of a Reifenhäuser extruder
The Reifenhäuser Group has been following the path of the corporate carbon footprint for 10 years now. The machine manufacturer is energy certified according to ISO 50001 and reduces its emission sources every year. This year, for example, this includes the installation of a new photovoltaic system with which Reifenhäuser can produce more than 600,000 kWh of electricity and save approximately 175,000 kilograms of CO2 equivalents.

In addition, the PCF of components, such as screws and barrels, and of entire extruders was determined. One finding is that emissions during the production of the line components are significantly lower than emissions during the use phase. For example, the production of a 120 extruder generates a calculated one-time emission of around 27,000 kilograms of CO2 equivalents. In contrast, the operation of the extruder causes around 3.5 million kilograms of CO2 equivalents through electricity consumption over the course of ten years. In this case, the manufacturing process causes less than one percent of the PCF along the life cycle. By contrast, 99 percent is generated during the use of the extruder - so the leverage for reducing emissions is much greater at this stage. For extruder operators, investing in energy-efficient technologies and subsequent energy-saving measures is therefore doubly worthwhile - both the wallet and the environment benefit.

Cross-vendor approach: Reifenhäuser launches digital offensive that focuses on enablement of film and nonwovens producers

Cross-vendor approach: Reifenhäuser launches digital offensive that focuses on enablement of film and nonwovens producers

Countless producers of films and nonwovens could be more productive today if they fully exploited the enormous potential of digitalization. Reifenhäuser presents therefore a digital offensive at K 2022 to help all producers get started with digitalization. In doing so, the company is focusing on the empowerment and independence of customers - and is deliberately turning away from the usual vendor-centric approaches. Instead, Reifenhäuser offers easy-to-implement, open digital solutions designed to help producers of films or nonwovens worldwide to increase their production efficiency (OEE) independently and sustainably. All customers, regardless of company size, thus benefit from a new dimension of process transparency that for the first time includes all line manufacturers and line types of a production.

The core of the digital solution is the so-called c.Hub, a middleware that ensures the secure exchange of data between different IT systems, applications, extrusion machines and line controls. This includes Reifenhäuser systems as well as third-party systems. The c.Hub becomes the single point of truth for all production-relevant data by merging and harmonizing production data streams. The central advantage is that all users can access all data from anywhere at any time and document them securely. The data is collected and stored on premises without interfering with the production process. The producer retains full control over the data at all times.

"So far, digitization in our industry has mostly failed due to heterogeneous factories with machines and peripherals from different vendors and of different ages and types, as well as applications that are not connected with each other," says Daniel Kajan, Director Product & Operations at RE:, a Reifenhäuser Group subsidiary specializing in digital products for extrusion line operators. "Without looking at the big picture, however, production is inefficient and error-prone. Unnecessary complaints, material loss and downtime are the result. Only a cross-vendor solution maps the production reality of our customers and thus offers real benefits," Kajan continues.

To enable customers to easily connect all their equipment in production, Reifenhäuser offers out-of-the-box connectors for the most important industrial protocols. They enable fast and complete acquisition of all production data. The associated ExtrusionOS software provides user-friendly applications and dashboards that help monitor, manage, store and analyze this data. Line operators can, for example, monitor the condition of their connected equipment and adjust it optimally based on the knowledge gained. They also have the option of monitoring defined thresholds and KPIs and, if desired, receiving notifications when thresholds are exceeded. This enables users to act faster and more efficiently, thereby significantly reducing errors and customer complaints. Legal requirements such as compliance with EFSA-relevant threshold values when processing recyclate for direct contact with food can be monitored and documented securely.

"Our open digital ecosystem helps line operators capture all production data from the first meter to the last meter of the roll, easily gain insights from it, and benefit from their data in the long run," Kajan explains. The digital package can either be purchased together with Reifenhäuser machines or retrofitted on existing lines and servers.

Highly wear-resistant screws and barrels enable safe recyclate processing

Highly wear-resistant screws and barrels enable safe recyclate processing

Whether film manufacturer, injection molder or line manufacturer: the processing of recyclate involves many challenges because recyclate is a rather complex raw material and a stress test for the plasticizing unit. Highly wear-resistant barrels and screws from Reifenhäuser Reiloy give the unit a long service life and ensure high product quality.

Recyclate is often a grab bag, because it is not always clear how carefully the starting material has been sorted and cleaned, or which additives and possibly aggressive residual components are contained. In addition, high-quality recyclate processing requires special additives that enable the polymer to become a high-quality product again. However, many of these additives are also challenging because, among other things, they have an abrasive effect or adhesive tendency - others have an aggressive effect due to inorganic acids. Many colorants and fillers also stress the components.

Reifenhäuser Reiloy offers a reliable solution for this with its highly wear-resistant screws and barrels and regularly sets benchmarks in terms of quality and performance. The components offer a demonstrably longer service life, precise matching of raw materials and additives, exclusive alloys developed in-house, and process-optimized surfaces. Manufacturers of injection molded and extruded products thus benefit from the best cost-benefit ratio in the industry. Higher resistance to wear is provided by special iron-based alloys and nickel-based alloys that match the raw material being processed. The decisive factor here is the composition of the alloys, because wear protection depends not only on the hardness of the layer.

Ralf Pampus, Managing Director at Reifenhäuser Reiloy, explains: "We are the only screw and barrel manufacturer to develop and produce the hard material alloys - and even the powders required for wear protection - in-house in our own materials laboratory. This means we offer expertise across the entire process that is unique in the market. Recent independent tests have again proven that Reifenhäuser Reiloy's wear protection is the best on the market and that the investment pays off - because high-quality components need to be replaced less frequently, produce consistent quality and thus ensure the productivity of a line."

Reifenhäuser Reiloy has decades of experience in wear protection systems and takes a holistic approach to wear protection consulting. The Reiloy experts calculate the optimum interaction between barrel and screw for each plasticizing unit and select the appropriate surface treatment.

Record output rates beyond 600 kg/h for form-fill-seal sack applications with Reifenhäuser Ultra Cool 2.0 FFS

Record output rates beyond 600 kg/h for form-fill-seal sack applications with Reifenhäuser Ultra Cool 2.0 FFS

Reifenhäuser Blown Film is introducing a new high-performance cooling system for its "EVO FFS" blown film line, which has been specially developed for heavy-duty sack applications. This system increases the cooling capacity by more than 20% compared to conventional systems on the market. In the production of heavy-duty sacks, record output rates of more than 600 kg/h can thus be achieved from a die with a diameter of 175 mm - while maintaining the best film properties.

The production of blown film for form-fill-seal (FFS) bags for heavy goods puts manufacturers in a tough competitive environment where output is the key to economic success. Thanks to the increased cooling capacity, producers can now exceed the market's peak output values by around 50 to 100 kg and thus secure a significant competitive advantage in terms of productivity.

Eugen Friedel, Director Sales at Reifenhäuser Blown Film, explains: "With our record output capacity beyond 600 kg/h, we enable our customers to achieve an attractive return on investment and the potential to be successful on the market in the long term. EVO Ultra Cool 2.0 FFS achieves unrivaled performance values without compromising quality or process reliability."

EVO Ultra Cool 2.0 FFS is suitable for all common FFS formulations and applications (petrochemical, fertilizer, salt bags, etc.) while offering ease of use and high line availability. In terms of mechanical film properties and thickness tolerances, the best results have been demonstrated in all product tests, enabling high throughputs in the filling process and stability for bag handling. Long service life, easier machine start-up and reliable quality also ensure high competitiveness and ease of operation. In order to also participate in the growing market for sustainable products, the line safely processes recyclates and recyclable raw materials.

In addition to the premium version "EVO ULTRA COOL 2.0 FFS", Reifenhäuser also offers the standard version "EVO COOL FFS" for its EVO FFS lines, so that the perfect solution can be found for every requirement - but its performance is always above the market average. All EVO FFS lines are equipped with Reifenhäuser's proven EVO extruders and blow heads, thus ensuring optimum melt quality at lowest melt temperatures.

Fully recyclable pouch – now also with barrier effect for food packaging.

Fully recyclable pouch – now also with barrier effect for food packaging.

At K22, Reifenhäuser Blown Film will be presenting a fully recyclable pouch with a barrier effect against oxygen and water vapor that is suitable for food packaging. The solution is a further development of the all-PE mono-pouch already established on the market. The Reifenhäuser Barrier Pouch makes a further contribution to higher plastic recycling rates and a functioning circular economy.

While fully recyclable pouches for non-food packaging have been established on the market for some time, the necessary oxygen barrier in food packages - and the materials and film thicknesses required for this - has stood in the way of their recyclability. The Reifenhäuser barrier pouch achieves the necessary barrier effect with an EVOH content of less than five percent and thus meets all the requirements for complete recycling. The use of the patented EVO Ultra Stretch stretching unit makes it possible: it increases the barrier effect of the EVOH by stretching and thus reduces the EVOH content while maintaining the barrier effect.

Eugen Friedel, Director Sales at Reifenhäuser Blown Film, explains: "The demand for recyclable products is growing steadily. This also increases the demand for EVOH, which is already hard to come by. With our fully recyclable barrier pouch, we meet two challenges at the same time: the pouch meets all market requirements for sustainable packaging and at the same time enables resource-saving handling of scarce and high-priced EVOH."

As before, the film produced can be further processed and converted without any problems. Thanks to the patented position of the stretching unit directly in the haul-off of the blown film line, the film is stretched at the ideal time and from the first heat, which makes the process particularly efficient and stable.

EFSA/FDA-compliant production process enables manufacture of food-safe film from PET recyclate

EFSA/FDA-compliant production process enables manufacture of food-safe film from PET recyclate

Reifenhäuser Cast Sheet Coating has developed a particularly efficient production process with which PET recyclate can be processed directly into food-safe film without a pre-drying process. The process meets the criteria of both the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). This was proven via a so-called challenge test.

If recycled goods come into direct contact with food, special certification by the EFSA or the FDA is required in advance in some markets. The production of films for such food packaging is correspondingly complex and demanding. Reifenhäuser Cast Sheet Coating now facilitates the economical production of such films for flat film manufacturers with a simpler production process and provides advice on certification.

Mark Schuster, Product Manager PET Sheet at Reifenhäuser Cast Sheet Coating, explains: "The market for recyclable food packaging made of PET already has a high volume. At the same time, the growth potentials are equally interesting considering the current global collection rates. We are now making it easier for customers to successfully participate in this market."

The EFSA/FDA-compliant PET process uses a co-rotating twin-screw extruder and a specially developed high-performance vacuum system that enables producers to process PET recycling material directly, without pre-treatment and pre-drying - as is necessary with other processes. Processors thus save the investment in an additional line component and avoid additional energy and maintenance costs, which leads to significant savings, especially in times of rising energy prices. Fast material and product changes are also possible, for example between post-consumer PET bottle scrap (PCR), post-industrial PET production waste (PIR) and virgin PET. The end product, for example a meat tray, meets the highest hygiene standards and can be used safely in direct contact with foodstuffs in accordance with the criteria of the authorities.


Certification made easy: Consulting

Reifenhäuser Cast Sheet Coating supports customers in the certification process with the relevant authorities. For this purpose, not only the cleaning process of the ground material, but also the quality monitoring of the input material and the production under the criteria defined by EFSA are considered.


EFSA audits made easy: automatic documentation

Another feature of the line is the automatic documentation of relevant production data. For EFSA audits, recipe- and product-related data of the certified process must be stored for several years. The specially developed ExtrusionOS Production Compliance software bundle helps to monitor and securely document production processes and compliance with EFSA-relevant thresholds in a data-based and real-time manner. A live dashboard transparently shows ongoing production and its thresholds, enabling fast action in case of irregularities. ExtrusionOS Production Compliance is based on Reifenhäuser's connectivity solution ExtrusionOS Core & c.Hub Middleware, and can also be retrofitted to existing lines.


Recycling made easy: digital product passport

Via ExtrusionOS, production data can also be transferred to a digital product passport - for example, via the open R-Cycle standard. Digital product passports are data records clearly linked to primary and end products that contain relevant data on materials, ingredients and the use of the product. Via special markings, they can be used, among other things, for data-based and thus more precise waste sorting and recycling processes.

New "Ultrathin Coating" process enables production of particularly lightweight and cost-effective Film/nonwoven composites

New "Ultrathin Coating" process enables production of particularly lightweight and cost-effective Film/nonwoven composites

Reifenhäuser Cast Sheet Coating will showcase a completely new production process for cost-effective film/nonwoven composites with outstandingly low grammage, which allows economical production also in Europe.

The Covid-19 pandemic and current supply shortages have exposed the dependence of companies on global supply chains. This situation is both a warning signal and an opportunity to boost and reorganize the local production of semi-finished products from the ground up. Reifenhäuser Cast Sheet Coating has now developed a trend-setting production process termed Ultrathin Coating, in particular for the sector of medical protective clothing. The process will permit customers to produce particularly lightweight film/nonwoven composites with greater cost efficiency and, as a result, more competitively.

The patent-pending process has several advantages: It cuts film grammage by 66%; material consumption in the overall composite is reduced by 28%; and it slashes costs by up to 34% compared to conventional semi-finished products. Significant cost savings are achieved in various ways, for example, by replacing hotmelt adhesives, which rises line availability by reduced maintenance effort at the same time.

Mark Borutta, Sales & Marketing Specialist at Reifenhäuser Cast Sheet Coating, explains: "We are currently experiencing a sustained increase in demand for medical protective clothing combined with a return strategy for local production capacity. Against this backdrop, producers achieve a fast return on investment and high profitability with Ultrathin Coating - even when production is based in Europe."

Even if manufacturers already produce medical protective clothing and prefer to handle the coating process internally in the future instead of importing the necessary composites, it is worthwhile to set up an in-house production facility. In either case, the investment in Ultrathin Coating usually pays for itself in less than 12 months. The lower material input also reduces the consumption of fossil raw materials and this in turn responds to the increased demand for more sustainable products.

What is so special about Reifenhäuser Cast Sheet Coating’s solution is that its sister company, Reifenhäuser Reicofil, an experienced and global leading manufacturer of nonwoven lines, provided their invaluable support to the development. Customers already operating a Reicofil nonwovens line or installing a new one will thus receive a perfectly matched extrusion coating line for seamless semi-finished product production.

26 companies present R-Cycle at K 2022: digital product passport enables circular economy for plastic products

26 companies present R-Cycle at K 2022: digital product passport enables circular economy for plastic products

R-Cycle - the digital product passport for plastic products - enables all stakeholders in the value chain to easily exchange recycling-relevant information in an open standard format across company boundaries and make it accessible for various applications, such as improved waste sorting. A total of 26 leading companies and organizations will present R-Cycle at K 2022 as part of a joint booth in the Circular Economy Forum (OA 16 / CE 07).

Dr. Benedikt Brenken, Director R-Cycle, explains, "More and more leading companies along the entire value chain are relying on R-Cycle and benefiting from the added value of standardized data exchange along the life cycle of plastic products. At K 2022, we will be showing a wide variety of applications and product samples that have already been manufactured in high volumes and whose data can be accessed via automated digital product passports."

Looking at today's waste streams, recyclable products - especially plastic packaging - cannot be sorted with sufficient accuracy for high-quality recycling. With R-Cycle, production machines read and record relevant data in a digital product passport, route it through the value chain, and make it retrievable via appropriate marking (e.g., QR codes or digital watermarks) on semi-finished and final products. In this way, waste sorting lines can easily identify recyclable packaging and form recycling-friendly and single-variety fractions. This is the basis for obtaining high-quality recyclates and building a functioning circular economy.

In addition to improving product sustainability, manufacturers also increase their process efficiency and product quality by using the digital product passport. Accurate information about source materials accelerates and optimizes production, while capturing proprietary product characteristics adds value for customers in the downstream value chain.

"Data exchange is the key to an efficient circular economy," Dr. Brenken adds. "The data is already available at the individual stations of the value chain. They just need to be transmitted, aggregated and made usable via an open standard. This is exactly what we offer with R-Cycle."

R-Cycle was developed to market maturity by various technology companies and organizations along the entire lifecycle of plastic products and can be networked with all systems (e.g., PPS, ERP) and production facilities: from film, blow molding or injection molding machines to processing, packaging and filling machines to waste sorting and recycling lines. The traceability technology behind R-Cycle is based on GS1 standards - the leading global network for cross-industry process development and a founding member of R-Cycle.

R-Cycle is an interoperable infrastructure offered as software-as-a-service. In addition, an open community exists for interested companies, institutions or stakeholders who want to use, support or further develop R-Cycle. Members gain access to a broad network of application-experienced partners and know-how in digitalization and sustainability. The goal is to realize individual applications, generate benefits by networking the value chain and jointly establish R-Cycle worldwide. Interested companies can obtain all information about membership at: www.r-cycle.org/en/community


R-Cycle was awarded the prestigious "Sustainability Award" in the category "Driving the Circular Economy" in September 2022. The award was presented during this year's "Sustainable Packaging Summit" in Lisbon. The event is the leading international forum for sustainable packaging.
