From the Sector

Helmut Bacher, co-founder of Austrian plastics recycling machine manufacturer EREMA and former managing partner, passed away on 20 September at the age of 81.

Helmut Bacher is regarded as a pioneer of plastics recycling. Together with his two colleagues Georg Wendelin and Helmuth Schulz, Helmut Bacher founded EREMA Engineering Recycling Maschinen und Anlagen Ges.m.b.H. in Linz, Austria, in 1983. Their life’s work was acknowledged in 2008 when the three founders received the Golden Award of Honour from the Province of Upper Austria.

Helmut Bacher displayed visionary foresight and open mind in playing a key role in shaping the plastics recycling industry. Following his training as a fitter and completing his schooling as a mechanical engineer, he worked in various technical positions before moving to a mechanical engineering company for plastics processing in the early 1970s. Helmut Bacher shared with his two colleagues a belief in the potential of plastics recycling. During countless trials, he searched for the right solution - until he found it. Despite initial adversity, the three founders remained convinced of the idea of a cost effective recycling machine for plastic waste and started up their own company in 1983.

At the K trade fair in Düsseldorf in 1983, EREMA presented a simple, robust, reliable and economical recycling system, signalling the start of a success story. The young company produced its first orders in modest premises in Leonding with two small workshops and a double garage. Today, the plants and components supplied by the EREMA Group achieve recycling capacities of over 25 million tonnes of plastic per year worldwide.

Up until his retirement from company management in 2004, Helmut Bacher was a driving force behind the company and remained closely associated with the EREMA Group until his death. His technical ability, coupled with solution-orientated thinking and genuine appreciation of his employees, have left a lasting impression and continue to shape the company to this day.

Neste is expanding its logistics infrastructure for liquefied recycled raw materials at its refinery in Porvoo, Finland, including materials such as liquefied waste plastic and liquefied rubber tires. This lays the foundation to handling larger amounts of liquefied raw materials to support Neste’s strategic aims to advance chemical recycling and transform the Porvoo refinery into a renewable and circular solutions hub.

The new logistics installations comprise dedicated unloading facilities: At the refinery’s harbor, Neste is building an unloading arm with a heating system as well as pipelines to connect the harbor with dedicated storage tanks. Unlike regular crude oil, liquefied waste plastic or discarded rubber tires require heating to stay liquid. At the same time, the systems need to come with higher resistance to corrosion. In addition to the unloading arm and pipelines, Neste is also building a vapor recovery unit, contributing to emission control of the operations.

The new logistics infrastructure is expected to be completed in 2024. It will, therefore, be available when Neste finishes construction of its liquefied waste plastic upgrading unit at the Porvoo refinery, which is currently being built as part of the project PULSE, planned to be finalized during 2025. At the upgrading unit, the liquefied raw materials are turned into high-quality feedstock for the plastics and chemicals industry.

As of July 1, Marcel Perrevort has been appointed Chief Sales Officer (CSO) of the Reifenhäuser Group. He succeeds Ulrich Reifenhäuser, who had been in this position for more than 25 years. With this decision, the family-owned machinery and plant manufacturer is consistently continuing the already initiated generational transition in its management structure.

Perrevort has held various sales and management positions within the Reifenhäuser Group for over ten years - most recently as Managing Director of Reifenhäuser Blown Film. In his new role as CSO, he is primarily responsible for the Group's sales and service strategy and its alignment with the activities of the business units.

Ulrich Reifenhäuser will continue his work in associations and committees within the plastics industry and will remain at the disposal of the Reifenhäuser Group as a representative and consultant with adjusted work hours.

The Toulouse Biotechnology Institute (TBI), a joint INSA Toulouse/ INRAE/ CNRS research unit, and Carbios, a French green chemistry company pioneering the world of bioplasturgy, presented a study entitled ”An engineered enzyme embedded into PLA to make self-biodegradable plastic”. This study reinforces Carbios and TBI's pioneering work in the field of enzymatic degradation of plastics.

The work describes the engineering strategies deployed to ensure the development of an enzyme capable of biologically depolymerizing polylactic acid (PLA)-based plastic materials over a wide temperature and pH range, reflecting the natural variations found in the life cycle of domestic compost.

It also describes the methodologies and challenges involved in obtaining homogeneous incorporation of the enzyme into PLA films at high temperatures (170°C), while retaining sufficient activity to enable the plastic produced to degrade completely and rapidly under domestic and industrial composting conditions, as well as in anaerobic digestion (methanization). It highlights the optimization process used to obtain an enzyme capable of withstanding the 170°C required to melt it into PLA by extrusion. The new enzymatic material is shown to disintegrate and biodegrade at a much faster rate than the 26 weeks required for certification for use in home composting, and also to help produce more biomethane, another source of waste recovery. It is also stated that the enzymatic material remains intact during long-term storage, and that its degradation will only be activated when transferred to composting or methanization conditions, thus guaranteeing its compatibility with PLA-based commercial applications such as flexible packaging or short-life items like food containers.

This work was mainly carried out within the INSA/Carbios PoPlaB (Polymers, Plastics and Biotechnology) cooperative laboratory at TBI and was supported by a grant for scientific research (THANAPLAST project, OSEO ISI contract number I 1206040W).

On August 1, Marius Berlemann took over as the new Managing Director for Operations. The personnel change is accompanied by a restructuring of management responsibilities.

From now on, Messe Düsseldorf’s leisure trade shows will be consolidated under the leadership of the operative management. To that end, the responsibility for boot, a large watersports show, will shift from President & CEO Wolfram N. Diener to Marius Berlemann. The new Managing Director for Operations will also be in charge of CARAVAN SALON Düsseldorf, a leading international trade show for mobile travel.

In turn, drupa, the global No. 1 trade show for printing technologies, will no longer be a part of operative management, instead moving to Wolfram N. Diener, who’s already in charge of many of Messe Düsseldorf’s industrial trade shows: a leading global trade show for the wire and tube industries, wire und Tube; an international valve trade show, VALVE WORLD EXPO; a packing trade show, interpack; a leading trade show for the metallurgy and foundry industries, GIFA, METEC, THERMPROCESS and NEWCAST; and numerous other trade shows of the portfolios. One recent addition is XPONENTIAL, a trade show for uncrewed systems and robotics in the U.S., which in February 2025 will for the first time host a European spinoff event in Düsseldorf: XPONENTIAL Europe.

Besides boot and CARAVAN SALON, Marius Berlemann will be in charge of the trade show for plastics and rubber, K; a leading international trade shows for medical devices and healthcare, MEDICA and COMPAMED; a leading trade show for rehabilitation, prevention, integration and care, REHACARE; a trade show for Wines and Spirits, ProWein; a retail trade show, EuroShop; a trade show for retail technology, EuroCIS; a trade show for the glass industry, glasstec; a global trade show for occupational safety and health, A+A; an international cosmetics and wellness trade show, BEAUTY DÜSSELDORF; and aninternational trade show for hairdressers, TOP HAIR; plus a number of international trade shows in the respective portfolios.

While the operative business has been reorganized, Bernhard J. Stempfle, Managing Director Finance and Infrastructure, will continue to be in charge of the entire finance department as well as of the Digital Strategy & Communication division and the Technology division.

Consisting of Wolfram N. Diener, Marius Berlemann and Bernhard J. Stempfle, Messe Düsseldorf’s management is optimally positioned to work side by side with the entire workforce to elevate the company’s competitive edge.

The current European Football Championships 2024 in Germany will be played on natural turf, which is very costly to maintain, does not tolerate high frequency of use and has a limited service life of only 6 months in some cases. Artificial turf is easier to maintain and correspondingly popular. In Germany, there are estimated to be more than 5,000 artificial turf pitches and as many as 25,500 across the EU. The drawback: the enormous annual emission of microplastics in the form of infill material, the high CO2 impact and the not environmentally friendly disposal. Researchers in Aachen presented a sustainable alternative: BioTurf is a new artificial turf system made from bio-based polymers that no longer requires polymer infill material!

"Every year, around 500 kilograms of plastic granules are produced per artificial turf pitch, which have to be refilled as infill. This also corresponds to the amount that potentially enters the environment as microplastics per sports pitch," explains Dr Claudia Post from TFI. With an estimated 25,000 artificial turf pitches in the EU, artificial turf in Europe alone produces 12,750 tonnes of microplastics that end up in the environment every year! The TFI - Institut für Bodensysteme an der RWTH Aachen e.V., Institute for Research, Testing and Certification in Europe for Indoor Building Products, has developed the innovative artificial turf system together with the ITA (Institute for Textile Technology at RWTH Aachen University) and in collaboration with the company Morton Extrusionstechnik (MET), a specialist in artificial turf fibres.

"New artificial turf pitches will be phased out by 2031 at the latest due to the ban on plastic granules. Even now, artificial turf pitches with infill material are no longer being subsidised," says Dr Claudia Post. For grassroots sports, clubs, cities and local authorities, converting their existing artificial turf pitches will be a mammoth task in the coming years, as artificial turf pitches have to be replaced every 10-15 years. With BioTurf, an environmentally friendly alternative is now available! The surface can be played on like any other, whether running, passing or kicking. Short, heavily crimped blades support longer blades and this simple approach increases playing comfort. BioTurf fulfils all quality requirements and standards for the highest footballing demands.

"BioTurf is an innovative, holistic solution," emphasises Dirk Hanuschik from TFI. "We use rapeseed oil and agricultural waste that does not compete with food production. BioTurf is also almost completely recyclable".
This is in stark contrast to conventional artificial turf, which can currently only be thermally utilised, i.e. burned to generate heat.

As BioTurf does not require the traditional latex process at all, the energy-intensive drying process can be dispensed with, which has a positive effect on the price. Latex is also difficult to recycle. In contrast, BioTurf uses the new thermobonding technology. Here, the thermoplastic pile yarns are thermally fused to the backing. Further development steps still need to be taken in the endeavour to develop a 100% mono-material artificial turf, as a few percent polypropylene still needs to be processed in the backing in addition to the polyethylene fibre material in order to protect it during thermobonding. However, this does not hinder its recyclability.

At PRSE in Amsterdam, the DischargePro control system from EREMA's POWERFIL business unit was presented with the Plastics Recycling Award Europe in the "Recycling Machinery Innovation of the Year" category. The smart technology for the EREMA laser filter improves process stability over the entire operating period and reacts automatically to fluctuations during the recycling process.

The DischargePro system automatically compensates for fluctuations in the input material, thereby ensuring uniform thickening during melt filtration and thus a consistent process. Depending on the application and contamination, POWERFIL was able to reduce melt loss by up to 50 percent with the DischargePro compared to the previous EREMA laser filter control system. These facts convinced the jury, who described the technology as an intelligent technological advance in the extrusion process.

With the DischargePro control system, POWERFIL significantly increases the degree of automation in the filter process. The discharge control system reacts to specific disruptions in the process. In this way, the speed of the scraper star is adjusted at short notice and returns to the setpoint speed as soon as the contamination peak has been discharged. Furthermore, the control system also recognizes changes in throughput and adjusts the discharge rates accordingly. In the event of a higher pressure drop across the filter screen, which is caused by a higher viscosity of the melt, DischargePro adjusts the setpoint value to ensure a consistent discharge rate. Long-term changes, such as the condition of the filter screen, are also taken into account in all adjustments.

The EREMA Group, based in Ansfelden near Linz, Austria, closes the financial year 2023/24 with total revenues of EUR 380 million. A joint venture with the Lindner Group sees the group of companies expand its portfolio to include washing technology. EREMA Group GmbH now has eight subsidiaries: EREMA, PURE LOOP, PLASMAC, KEYCYCLE, Lindner Washtech, UMAC, plasticpreneur and 3S.

"With our machines and components, we have now reached a recycling volume of more than 25 million tonnes per year worldwide, which makes a significant contribution to the development of a circular economy for plastics," says Manfred Hackl, CEO of the EREMA Group. The group of companies manufactured 290 extruders for recycling plastic in the past financial year, supplemented by over 100 add-on components such as filter systems and ReFresher anti-odour technology. These recycling solutions generated total sales of EUR 380 million. Around 8,500 machines and components from the group are in operation in more than 100 countries. The EREMA Group employs 950 people worldwide.

Strategic investments in all areas of the plastics recycling industry
In recent years, the EREMA Group has invested in developing specific machines, applications and infrastructure. "The opening of the new R&D Centre in Ansfelden last summer and the new machines in the Customer Technology Center at EREMA North America at the beginning of this year, have seen us complete the largest phase of investment in our history to date. We have invested more than EUR 110 million in the expansion and modernization of our international locations over the past five years," emphasizes Horst Wolfsgruber, CFO of the EREMA Group. Another important milestone is the founding in August 2023 of the holding company BLUEONE Solutions together with the Austrian family-owned company Lindner. Incorporating Lindner Washtech means that the EREMA Group's extensive portfolio now also includes washing technology.

Developments in post consumer and PET recycling
The new DuaFil® Compact technology, which EREMA developed specifically for challenging applications with high levels of contamination and moisture, is proving successful. Since the launch at K 2022, around 20 INTAREMA® TVEplus® DuaFil® Compact systems have been sold. In the post consumer segment, ReFresher technology for the production of odour-optimised recycled pellets is also gaining ground and is now in use worldwide with a total capacity of one million tonnes per year for film and regrind applications. Another interesting new component is the DischargePro control system for the EREMA laser filter, which has been nominated for this year's Plastics Recycling Awards Europe. The discharge control system responds automatically to fluctuations in flow rate during the recycling process and reduces melt loss by up to 50 percent. With its new Fast-Track scheme, EREMA is responding to the demand for machines available at short notice at an attractive price-performance ratio.

For bottle applications, VACUREMA® systems have been proving their performance for 25 years. Over 400 EREMA PET systems for food grade are in operation worldwide, notching up a total capacity of more than 4.5 million tonnes per year. PET recycling is also becoming increasingly important in the textile industry. FibrePro:IV technology was developed especially for fibre-to-fibre recycling, which is used together with machine combinations from EREMA or PURE LOOP, who specialise in shredder-extruder technology, depending on the geometry and contamination of the PET fibre waste. For these applications, the EREMA Group has set up a fibre technical centre at its headquarters in Ansfelden.

Big potential for plastics recycling
The amount of plastic produced worldwide is currently around 400 million tonnes per year - and the figure is still rising. Around 9 percent of it is recycled globally. This represents big potential for the EREMA Group, as Manfred Hackl emphasizes.

Polyurethane has become an integral part of our daily lives, whether in the construction industry, in leisure activities, in the manufacture of furniture or in numerous other applications. The precision gear pumps from Oerlikon Barmag, which will be presented at this year's UTECH Asia / PU China 2024 in Shanghai, impress with customised solutions for demanding tasks in the chemical industry. They increase the productivity of the often complex manufacturing processes for this wide range of applications.

Oerlikon Barmag pumps handle demanding processes in PUR applications, in the chemical, plastics or paint and lacquers industries. One of the greatest challenges lies in the accurate and reliable metering of toxic or low-viscosity media. With the GM and GA series and the associated components, Oerlikon Barmag presents the optimum equipment for these applications.

GM pump
Pumps in the GM series achieve precise dosing by feeding the flow with low pulsation. The multi-stage GM pump conveys low-viscosity media even under high pressure and the most difficult operating conditions (e.g. 250 bar, 100 mPas). The standard pump for many dosing tasks is the GM series in a square design. With the development of the multi-stage pump, the range of applications for the GM series has been significantly expanded. The round 2-stage GM pump has been specially developed for use in high-pressure technology. It fulfils the special challenge of pumping small flow rates with low viscosities. The pump serves flow rates from 0.05 to 20 ccm/rev and is therefore particularly suitable for the production of PUR moulded parts, block foam, refrigeration unit insulation or sandwich panels.  

GA series
Making products and processes more efficient is a constant challenge for manufacturing companies. This is why Oerlikon Barmag has added the GA series to the GM series especially for the demanding conveying of high-viscosity media. The GA series is available in delivery volumes of 1.25 - 30 cm³/rev (0.6-144 l/h). It is designed for pressures up to 200 bar, for viscosities up to 1,500 Pas and for temperatures up to a maximum of 225°C. With this pump series, Oerlikon Barmag offers customised solutions for process engineering processes where highly accurate and uniform metering is required.

The drum pump
The drum pump from Oerlikon Barmag is specially designed for conveying and dosing highly viscous materials such as adhesives, silicones and other highly viscous materials from drums and other large containers and for pressures of up to 250 bar. One of its special features is not only that it discharges highly viscous materials from the drum, but also that the medium can be dosed directly without an intermediate stop.

The gear pump and drum follower plate are synchronised so that the plate effortlessly reaches the bottom of the container, leaving behind only a very small residual quantity of < 1%. This reduces material costs and has a positive effect on the production process.
