From the Sector

The company launched the "Edvanced Recycling - EREMA Prime Solutions for Advanced Recycling" campaign at an exclusive press conference at the beginning of June as a preview to K 2025. 

"The technologies used in plastics recycling have evolved very fast. Over the past few years, we have repeatedly set milestones and have been a driver of innovation. At this year's K, we will again be presenting multiple new solutions designed to keep even more plastics in circulation," said Manfred Hackl, CEO of the EREMA Group, in his opening presentation at the K Preview Press Talk, which was held at the beginning of June at the company's headquarters in Ansfelden near Linz in Austria. EREMA provided a first glance of selected innovations that the company will be presenting at K 2025 in Düsseldorf. 

New technologies open up more applications 
Two new machine types will celebrate their début at K 2025: 

• TwinPro is a high-performance twin-screw technology in which the proven EREMA Preconditioning Unit (PCU) is coupled directly to a twin-screw extruder. The new system is particularly suitable for the highly efficient homogenisation in just one step of complex film waste with low bulk densities. 
• AGGLOREMA technology is particularly interesting for preparing feedstock materials for chemical recycling. This robust and energy-efficient system produces agglomerates with a high bulk density on a large scale from heavily contaminated post consumer material.

The focus is also on the increasing demand for recycled pellets made from post consumer materials in sensitive applications and secondary packaging. For example, EREMA is launching a more compact INTAREMA® TVEplus® 2021 and, together with Lindner Washtech, is presenting the optimum match of washing system and extruder that achieves a balanced overall process. Live recycling demonstrations in the outdoor area will show how different waste streams are processed. Visitors can see the results for themselves in the exhibition of products at the Edvanced Recycling Centre, which range from technical components to cosmetic products and food packaging. 

Digitalisation increases uptime
Digital solutions play a decisive role in achieving the circular economy and handling plastic waste material in a sustainable way. At K, the PredictOn family is growing to include AI-supported in-depth data analysis for monitoring the main drives, and a new Condition Monitoring System for the plasticising unit. Both modules can be seen in action at the show, where an INTAREMA® TVEplus® DuaFil® Compact is equipped with the latest intelligent assistance systems. The results can be seen live on the displays of the BluPort® online platform at the EREMA trade fair stand and at the outdoor Edvanced Recycling Centre.

Edvanced Recycling: The campaign with a recurring effect
"For a more circular economy in the plastics industry, recycling has to be consistently integrated along the entire value chain. Edvanced Recycling shows how we are working together with our customers to sustainably increase the proportion of recycled plastics used in new products," says Gerold Breuer, Head of Marketing at the EREMA Group. The year-long campaign focuses on the full range of EREMA solutions, from technologies proven in practice to innovative new products, with a first highlight at K 2025. "And yes, it really is spelt that way," adds Gerold Breuer, "because the E stands for EREMA. After all, advanced plastics recycling is inextricably linked to our name."

UMAC, a member of the EREMA Group, is expanding its ReadyMac product line with a new 60 hertz version. This means that the immediately available plastics recycling solution can now be deployed worldwide. The standardised machine with its particularly attractive price-performance ratio will be presented in its new look for the first time at Plast Eurasia from 4-7 December 2024 in Istanbul.
    
The ReadyMac celebrated its market launch at K 2022. The recycling system, which is produced in stock and therefore available at short notice, has since established itself successfully in the 50 hertz version, particularly on the European market. Based on this success, UMAC is now also offering the ReadyMac 500 in a 60 hertz version. "The ReadyMac is suitable for a wide range of materials and degrees of contamination, processing film, flakes and regrind into high-quality recycled pellets. The fixed price of just EUR 375,000 makes it an attractive proposition," says Michael Köhnhofer, Site Manager at UMAC. The machine is produced in small series at the St. Marien site.

The ReadyMac is based on EREMA's proven TVE technology, in which degassing occurs after filtration. Equipped with a robust SW RTF® screen changer filtration system, the recycling machine processes both printed and contaminated waste. The multipurpose screw handles a wide range of materials efficiently and reliably. With a throughput of up to 500 kg/h for LDPE, LLDPE, MDPE, PP, PS, PC, ABS and up to 450 kg/h for HDPE, the ReadyMac 500 is a true all-rounder. In addition, the two frequency converters on the main drives (preconditioning unit and extruder screw) ensure consistently high throughputs and quality for a wide variety of material types, such as regrind, film or nonwoven, even without changing the screw. This enhances both flexibility and productivity. The frequency converters are now included as standard with the ReadyMac.

Breaking new ground in plastics recycling means assessing the value chain from end to end. The big opportunities for the future are in fine-tuning the individual process steps; from the collection of recyclable materials to the recycling process and the end product. This is where the cooperation of Lindner and the EREMA Group comes in, officially launched following the 50/50 founding of the holding BLUEONE Solutions in August 2023 to which shares of Lindner Washtech were contributed. The expertise of EREMA, a manufacturer of extruders and filtration solutions for plastics recycling and the largest company within the EREMA Group, has now been combined with the expert know-how from Lindner Washtech, a leading provider of all-in-one solutions for shredding, sorting and washing plastic feed materials.

Data transfer ensures more efficient recycling processes
Process control is an especially important aspect of plastics recycling, which is why standardising the process control system was what the two companies focused on first. "Together, we have developed a platform that allows data to be exchanged between the extruder and the washing system," says Manfred Hackl, CEO of the EREMA Group at IFAT in Munich. "This enables us to analyse the data more precisely so that effective improvement measures can be deduced." All key parameters are taken into account and monitored via a digital interface. For example, it is possible to use information relating to the current throughput of the EREMA Pre Conditioning Unit to optimise the washing process as soon as possible so that it can compensate for fluctuations in capacity and achieve a significant increase in output. This data transfer represents a new step on the roadmap to digitalization.

High efficiency due to smart energy management
"To ensure sustainable recycling, it is necessary to find the right process for each application and to make sure that the individual process steps are perfectly coordinated," emphasizes Michael Lackner, Managing Director of Lindner. Coordinating the process steps has already achieved initial success in energy management, and a clear example of this is heat recovery. "We use the latent heat generated during the extrusion process as an energy source for the washing and drying process," explains Lackner. "This enables our customers to sustainably reduce their energy costs and carbon emissions".

Making the most of synergies along the value chain
Synergies need to be used to establish the quality standards specified for each end application. "The key question is how we can improve the end product and increase the overall efficiency of the recycling process at the same time," agree Manfred Hackl and Michael Lackner. This will only work if companies work together along the value chain. The industry leaders can already point to several examples where together they have improved recycling processes and made it possible to move away from downcycling. "An example of this is the recycling loop of HDPE starting material, which is processed into high-quality, food-safe rHDPE pellets using our two technologies," says Lackner. Lindner Washtech and EREMA continue to work intensively together to develop strategies for upcycling plastics and increase recycling rates.

On June 1, EREMA hosted the EREMA Discovery Day focusing on the post consumer segment from a European perspective. Live demonstrations showcased the latest machine innovations for PET and polyolefin recycling.

The invitation was accepted by around 400 customers and partners, mainly from Europe, to find out about the wide range of recycling technologies for PO and PET plastic waste. The technology that was presented and explained by EREMA experts and guest speakers during lectures in the morning, could then be seen live in-action in the afternoon when the recycling machines were demonstrated in operation. A total of six innovative recycling technologies were on display: INTAREMA® TVEplus® DuaFil® Compact, INTAREMA® TVEplus® RegrindPro® + ReFresher, the COREMA® cascade extrusion system, a VACUREMA® Inline Sheet line equipped with new EcoGentle technology, the new INTAREMA® FibrePro:IV machine, and the PCU-
TwinScrew. These allowed visitors to witness their performance and the high quality of recycled pellets that they produce.

"This wide range of technologies is necessary because the recycling process each of our customers choose depends on the type of plastic, the level of contamination of the input material, and which product will be made using the recycled pellets. Following the expansion of our Ansfelden site and with the new site nearby in St. Marien, we can now demonstrate all these processes, carry out test runs with customers' material and focus on development work independently of our Customer Centre," says EREMA's Managing Director Markus Huber-Lindinger.

EREMA is driving forward research and development work in the company's new R&D Centre. Two halls with a total area of 1,550 square metres and a new office building offering space for 50 workplaces has been built. Here, the company bundles cross-departmental test machines and laboratory facilities for post consumer and inhouse recycling applications. R&D is decentralised at EREMA. Employees from different departments handle process engineering challenges, innovations in mechanical engineering and automation technology - all with the aim of meeting customer requirements and achieving the highest possible quality of recycled pellets.  

On the evening before Discovery Day, EREMA celebrated its 40th anniversary together with customers and partners. A review covered the company's history - from the first workshop in a garage in 1983, to its position today as a innovation pioneer and one of the market leaders.
