GKD AT FILTECH COLOGNE 2026: MESH, COMPONENTS, AND PROCESS RELIABILITY FROM ONE SINGLE SOURCE Gebr. Kufferath AG will be presenting technical metal mesh, filter media, process belts, and furtherprocessed mesh components for reliable processes in demanding industrial applications at FILTECH Cologne 2026. With Mesh-in-Mesh, GKD is offering an exclusive preview of a new mesh technology ahead of its official product announcement.

GKD can be found in Hall 8, Stand B19, from 30 June to 2 July 2026.

KEY FACTS AT A GLANCE: The focus is on applications where process reliability, reproducible quality, and secure integration into existing systems are crucial.

• Mesh-in-Mesh combines coarse and fine mesh structures for greater energy efficiency in electrolysis.

• A video production insight into the Automotive Room concept shows the manufacturing of technical metal mesh components under nearseries industrial conditions.

• In the Process Belts segment, the focus is on VACUBELT for horizontal vacuum belt filters.

EXCLUSIVE INSIGHT: WEAVING TECHNOLOGY HOLDS THE PROMISE OF HIGHER EFFICIENCY With Mesh-in-Mesh, GKD is providing an early preview of a new mesh technology at FILTECH Cologne 2026, ahead of the official product announcement.

This approach was developed on the basis of many years of experience in water electrolysis.

GKD has translated specific customer requirements into a new mesh structure that aligns material, geometry, permeability, surface, and further processing. Initial scientific tests show that Mesh-in-Mesh is capable of increasing the energy efficiency of industrial electrolyzers.

SERIES QUALITY FOR PROCESS-RELIABLE MESH COMPONENTS In addition to solutions for specific applications, GKD will present its expertise as a provider that develops technical mesh into series-produced components for demanding industrial applications at its trade fair booth.

As an example, a video at the booth provides an insight into the Automotive Rooms in GKD’s production facilities worldwide, where GKD develops customer requirements into prototypes and produces them in series quality. The Automotive Rooms demonstrate how defined mesh properties and stable geometries are combined with reliable further-processing methods on the basis of many years of experience in industries and applications — ultimately resulting in automated manufacturing processes with reproducible, very high quality.

PROCESS EXPERTISE ACROSS NUMEROUS APPLICATIONS One of the many components manufactured in the Automotive Rooms is the spark arrestor, which serves as a flame arrester in battery modules. In addition to mesh selection, process expertise in sealing, joining, component geometry, differential pressure, and verification is incorporated into series production.

In many other industries as well — including chemicals, medical technology, aerospace, and technical protection applications — GKD combines its market experience with individual customer requirements to create seriesready production processes.

“For many customers, the mesh alone is not the decisive factor, but

rather the question of how it can be turned into a reliably manufacturable component,” says Markus Knefel, Product Developer at GKD. “It is precisely at this interface between mesh, component design, and manufacturing process that our expertise and experience pay off.”

VACUBELT FOR HORIZONTAL VACUUM BELT FILTERS With the VACUBELT belt model, GKD will also demonstrate the role of filter belts in continuous filtration and dewatering. The focus is specifically on horizontal vacuum belt filters, where the belt has a significant influence on process stability, dewatering performance, and filtrate clarity.

Typical applications range from the dewatering of phosphogypsum and FGD gypsum to potash, salt, and soda, as well as the dewatering of concentrates from processing operations for various ores.

VACUBELT filter belts are designed exclusively to match the application and the properties of the suspension.

“With our VACUBELT filter belts, the application determines the choice of mesh and the correct belt design,” says Philipp Wolff, Sales and Applications Manager at GKD. “Our task is to translate the requirements of diverse dewatering processes into robust, efficient, and high-performance belt solutions.” gkd-group.com

PLAST 2026: AN EDITION BEYOND EXPECTATIONS The twentieth edition of PLAST, the international exhibition dedicated to the plastics and rubber industry, successfully ended on June 12th at Fiera Milano, Rho. Four intense days of exhibition confirmed the event’s role as a benchmark for the sector, decisively overcoming the cautious outlook of the eve in a global geopolitical and macroeconomic context marked by severe uncertainties, trade tensions, and instability in international markets.

The final figures certify the success of the event: 35,000 attendees – with a significant share of foreign visitors equal to 25%, coming from 110 countries – and over 1,000 exhibiting companies, 44% of which were international. The entire event spanned an exhibition area of 40,000 square meters: an impactful result for a market undergoing a phase of profound transformation.

A COMPLETE SUPPLY CHAIN: FROM SPECIALIZED HALLS TO STARTUP INNOVATION The strength of PLAST 2026 certainly lay in its ability to capture a snapshot of the entire supply chain. Great interest was generated by the satellite shows and thematic areas: RUBBER, the meeting point for the elastomer industry, organized in collaboration with Assogomma; 3D PLAST LAB, developed with Indexlab – Politecnico di Milano, focusing on the frontiers of additive manufacturing; and PLAST MAT, the showcase dedicated to polymeric materials.

A fundamental added value in terms of new content was brought by the innovation ecosystem, thanks to the presence of around twenty Italian startups that presented cutting-edge solutions ready to be integrated into the manufacturing fabric to visitors.

A QUALIFIED AUDIENCE AND INTERNATIONALIZATION Among the most encouraging signs, the extremely high professional profile of the visitors stands out.

Thanks to the enhancement of the 10

strategic incoming project developed in collaboration with ICE Agency, among the approximately 9,000 international operators visiting, the presence of over 350 selected foreign delegates must be highlighted, who confirmed the strong attractiveness and commercial centrality of the fair.

Drawing the balance of this edition is Mario Maggiani, Managing Director of Promaplast: “We do not hide that our forecasts on the eve were marked by the utmost prudence. We feared far heavier repercussions of the global geopolitical situation on PLAST, which instead confirmed itself as a European point of reference for the plastics and rubber industry, restoring confidence to many of the exhibitors we met. The reality is that today the exhibition world, more than other sectors, is suffering the backlash of a diversification in ways of doing business, especially in the B2B field; this is why we are diversifying the format of PLAST, not only through the addition of satellite shows but also by providing a conference program capable of covering all facets of the supply chain and responding to the updating needs of a rapidly evolving sector.”

He is echoed by Alessio Fineo, Head of the Exhibition Department at Promaplast: “From the opinions gathered at the fair, many have noted the quality of the visitors and the delegations of foreign companies that showed interest in the products on display.

The efforts of the entire team to promote PLAST generated results that went beyond expectations.”

A TOP-TIER PROGRAM OF CONFERENCES AND SEMINARS Confirming the dynamism of the event was the success of the program of seminars and institutional conferences, which in some cases registered a full house.

The rich educational and debate palimpsest was made possible thanks to the fundamental synergy with the main stakeholders and industrial partners of the sector.

Meetings saw the close collaboration of leading trade associations and research entities – including Corepla, IPPR Plastica Seconda Vita, PlasticsEurope Italia-Federchimica, Unionplast, The European House Ambrosetti, TMP, Assorimap, Assogomma, Ipack-Ima, Largo Consumo, PVC Forum/VinylPlus Italia, and Made Competence Center I4.0 – who chaired the discussion tables, offering concrete answers to the regulatory and technological challenges of the future. https://plastonline.org/en/

IMPROVING SCREW FEEDER PERFORMANCE WITH FINE LOAM DUST Fine particulate materials do not always behave as expected once introduced into a dosing or screw feeding system. Following a customer enquiry involving the handling of fine loam dust, Trantec Solids Handling carried out material testing to optimise screw feeder performance for the application.

Although the material initially appeared relatively free-flowing, testing identified compaction and binding within the feeder during operation under continuous feeding and agitation.

Testing quickly highlighted build-up around the outlet tube and feed section, where the fine particulate content began binding to internal surfaces under compacted feeding conditions. This increased resistance within the feed area, generating grinding behaviour and high-pitched operational noise as compacted material passed through the system.

As material accumulation increased, screw loading became inconsistent, affecting feed stability and overall dosing performance.

The testing process proved critical in identifying how the material behaved under continuous compression,

12

Bulk Solids Today

shear, and agitation within the feeder. While the loam dust remained relatively free-flowing in bulk form, conditions inside the feeder introduced localised compaction and surface adhesion that would not necessarily have been identified outside of operational testing.

To address the issue, several targeted refinements were implemented to improve material flow and feeding consistency within the system.

IMPROVING FLOW THROUGH AUGER AND SURFACE REFINEMENT The screw auger was reworked with a bevelled edge profile and polished to a high surface finish to reduce friction and minimise material retention during transfer.

The bevelled geometry improved material movement through the feed path while reducing the likelihood of compacted product forming along the auger flights.

In parallel, the internal feed tube was polished to create a smoother conveying surface, lowering the coefficient of friction and reducing fine particle adhesion within the outlet section.

BULK MATERIALS HANDLING These refinements significantly improved product flow through the feeder while reducing material accumulation and resistance within the feed area.

PREVENTING BRIDGING AND IMPROVING FEED CONSISTENCY To further improve feeding stability, the feeder incorporated a contra-rotating agitator blade designed to maintain a continuous and even fill of the auger.

The agitator helped break material bridges and disrupt compacted powder formations before they entered the screw, reducing the risk of rat-holing and inconsistent screw loading during operation.

Combined with the polished surfaces and bevelled auger geometry, the agitation system delivered a more stable and consistent material flow performance throughout the application.

THE IMPORTANCE OF MATERIAL TESTING Material testing is considered a key element of successful screw feeder design and long-term material handling performance. Trantec Solids Handling understands that even materials which appear relatively free-flowing in bulk form can behave very differently once subjected to continuous feeding conditions inside a screw feeder system.

To support customers during the equipment selection and development process, Trantec Solids Handling

provides material testing free of charge to all customers to help ensure feeder performance is properly matched to the material and application requirements.

Fine powders and difficult bulk solids can exhibit flow characteristics that only become apparent during operational testing. Particle size distribution, moisture content, bulk density variation, and compaction behaviour can all significantly influence screw feeder performance once material is exposed to compression, shear, and agitation during operation.

In this application, material testing proved critical in identifying localised compaction and surface adhesion within the feeder, allowing auger geometry, surface finish, and agitation systems to be refined to improve long-term feeding stability and consistency.

Regular cleaning and preventative maintenance were also recommended to minimise future material build-up and maintain consistent feeder performance over time.

DANFOSS’ DEXTREME MAX SYSTEM REDUCES ELECTRIC EXCAVATOR POWER CONSUMPTION BY 35%, EXTENDING RUNTIME BY 53% Project funded with a grant from UK Government’s Red Diesel Replacement Phase 2 Competition Danfoss Scotland, part of global hydraulics and electric powertrain systems supplier Danfoss Power Solutions, has announced the results of its Dextreme Max system validation in a 30-tonne batteryelectric excavator. Undertaken with a £4.29 million grant from the UK Government, Danfoss demonstrated that its Dextreme digital hydraulic architecture reduced excavator power consumption by 35% across a representative duty cycle mix, corresponding to 53% longer runtime on a single charge.

The results confirm the potential of the Dextreme Max system to significantly increase energy efficiency and accelerate the electrification of large excavators.

Danfoss’ Dextreme Max system aims to cut excavator energy consumption by up to 50% by reducing energy losses and recovering energy that would otherwise be wasted. The system’s integral component is the DDP1X0D, a Digital Displacement® hydraulic pump/motor with multiple independently controlled outlets. The Dextreme Max system provides independent actuator supply, eliminates flow-sharing losses, and enables energy recovery from excavator motions such as boom lowering.

In 2023, Danfoss received a grant from the Red Diesel Replacement Phase 2 Competition, a program funded through the Department for Energy Security & Net Zero’s £1 billion Net Zero Innovation Portfolio, to develop and validate the Dextreme Max system. The program provided funding for projects developing lowcarbon alternatives to red diesel for the construction, mining, and quarrying sectors. Danfoss used the funding to procure a battery-electric excavator and integrate its Dextreme Max system into the machine. The grant represented approximately 65% of the eligible project costs, with Danfoss funding the remaining portion.

Danfoss selected a Develon DX300LC‑7 crawler excavator for the project. Originally diesel powered, the excavator was supplied in an electric configuration by Staad B.V., which replaced the engine with an electric drivetrain consisting of a 14

Bulk Solids Today

Danfoss Editron EM-PMI375 permanent magnet synchronous motor, EC-C1200 inverter, and MC050 motor controller, plus three 140-kWh batteries.

Danfoss engineers replaced the excavator’s conventional swashplate hydraulic pump with the DDP180D pump/motor. The excavator’s four primary services — boom, arm, bucket, and swing — are supplied through ten individually controllable outlets on the pump. These outlets are dynamically grouped through a ganging block, a digital distributor that reallocates capacity to the service requiring it. A dedicated valve operating as a hydraulic H-bridge was developed and applied to the boom function to allow independent metering, providing anti-cavitation, pressure amplification, and energy recovery during overrunning motions. Finally, the control system architecture was developed to provide real-time control of the hydraulic system, electric powertrain, and auxiliary subsystems.

BULK MATERIALS HANDLING

To compare system performance before and after conversion, multiple tests were carried out, including JCMAS air grading and JCMAS air dig and dump (equivalent to ISO/AWI TS 11152-2). Compared to the baseline electric excavator, the Dextreme Max system reduced battery energy use by 49.2% in air grading and 31% in air dig and dump, with negligible impact on cycle time. Assuming a duty cycle of 30% grading and 70% digging, Dextreme Max would reduce battery power consumption by 35% without significantly impacting work rate. This would result in 53% longer operating hours with the same battery capacity as the baseline machine, or similar runtime as the baseline with two battery packs instead of three.

“The results of this testing highlight the potential of digital hydraulic architectures to overcome the obstacles in heavy-duty machinery electrification.

Electric excavators offer excellent responsiveness, smooth control, a quiet cab environment, and zeroemission operation. With Dextreme Max, they can also deliver the runtime, productivity, and total cost of ownership advantages required for wider adoption, thereby accelerating the decarbonization of heavy-duty machinery,” said Alasdair Robertson, Senior Director, Digital Displacement, Danfoss Power Solutions. “We are extremely encouraged by these results, but there is more work to do. Further gains are possible, and we will continue optimizing the system to maximize the energy savings and value for our customers.”

Danfoss Dextreme systems offer an incremental approach to implementation through three levels: Swap, Flex, and Max. Dextreme Swap involves a simple pump replacement, offering improved system control and more efficient operation. Dextreme Flex introduces flexible allocation of the Digital Displacement pump outlets, reducing flow distribution losses and further improving efficiency. The Dextreme Swap and Flex systems are commercially available, and this project has advanced the path to commercialization for Dextreme Max.

KIBAG, one of Switzerland’s leading companies in the building materials and construction sector, has become the first company in the world to put an autonomous Develon ‘Real-X’ crawler excavator – a joint development with Gravis Robotics – into practical use. It may have been surprising to onlookers to see executives from leading companies in Switzerland, France, Germany and South Korea travelling to Tuggen for the handover of a crawler excavator and to watch it digging. However, a closer look would have revealed that there was no operator in the cab and that the machine was not being operated by remote control.

Urs Helbling, CEO of AG für Baumaschinen Schmerikon (AGFBS), the Develon dealer in Switzerland, explained that this moment had been preceded by two years of preparatory work. The key players here are the AI-powered Real-X system on a Develon DX225LC-7X excavator and a company that is open to the use of new technologies. “Today is a special day for all of us. This is no ordinary machine handover, but a step into the future of construction,” says Christoph Duijts, CEO of KIBAG. OPEN TO NEW TECHNOLOGY Founded in 1926, KIBAG is a family-run business, which employs more than 2000 people and operates primarily in three business areas: building materials, construction services and the environment and waste management. It operates 14 gravel pits, three quarries, 25 concrete plants and 17 construction companies specialising in road construction, civil engineering and specialist sectors. In addition, there are recycling and waste management companies as well as service providers in the leisure sector that form part of the business.

KIBAG CPO, Urs Kordeuter, explains that the company’s fleet comprises 2000 construction machines of all sizes. To ensure the fleet remains at the cutting edge

BULK MATERIALS HANDLING of technology, 200 of these are replaced annually. In the interests of sustainability, the company is currently investing particularly in electric-powered equipment and is collaborating with various construction machinery manufacturers – though not with Develon until now.

The reason this has now changed is that Develon is further ahead than other manufacturers in the field of autonomous machinery, according to Urs Kordeuter.

As a pioneer in autonomous machine technology, Develon, formerly known as Doosan Construction Equipment, unveiled its Concept-X system in 2019 and used this to showcase the unmanned construction site, where safety and efficiency are enhanced through the use of 5G networks, drone surveying and autonomous machine control. The aim – as with the Concept-X2 extension unveiled in 2023 – was to achieve full autonomy by 2030. At bauma 2025, Develon took the next step with Real-X, creating a new intelligent crawler excavator capable of autonomously carrying out trench excavation, earthworks and truck loading. Real-X is the result of an agreement between HD XiteSolution (HDX), the holding company of Develon, and Gravis Robotics AG. Founded in October 2022, Gravis Robotics is a spin-off from the Swiss Federal Institute of Technology Zurich (ETH). The company’s core expertise lies in developing learning-based control systems as retrofit kits and software that transform machines into fully autonomous robots capable of performing complex tasks.

Dominic Jud, CTO and co-founder of Gravis Robotics, explained that the company has gained experience through the use of autonomous machines in pipeline construction. “We were able to build on that, yet every project presents new challenges – be it the depth of the trench or the ground conditions,” said Dominic Jud. Just how mature this technology has become was recently demonstrated for 900 dealers, customers and trade journalists at the Develon Demo Days in the Czech Republic in April. Many were fascinated by the precision offered by this autonomous excavator solution.

EXCELLENT RESULTS The new machine in Switzerland is being used on the site of a former KIBAG quarry, which is now being restored to its natural state. The backfilling has already been completed, terraces have been created, and a road is also planned for the site in the future. Whilst the operation of autonomous construction machinery in public spaces is not yet clearly regulated, the machine can be operated autonomously on KIBAG’s private land, supervised by a technical supervisor.

Site Manager, Gabriel Hasler, has tasked the new Develon DX225LC-7X excavator with digging a trench 300 metres long, six metres wide and three metres deep.

This is to be filled mainly with rocky material to prevent the foot of the hill from slipping. “We are replacing poor-quality material with significantly better material,” explained Gabriel Hasler. “The machine is doing an exceptional job,” he said, much to the delight of Panyoung Kim and Gye-Bong Jang, Senior Vice President and Head of Robotics AI at HD XiteSolution, respectively, who watched the operation with pride. All parties involved

particularly emphasise how smooth and trusting the collaboration has been at every stage of the project.

“The idea for this project was conceived in 2024 based on a prototype from Develon,” Urs Helbling, CEO of AGFBS, added. “We then made the necessary contacts at bauma 2025, and in the summer of 2025, KIBAG decided to use the DX225LC-7X in this configuration,” he continued. It is precisely the shortage of skilled workers that makes a machine promising a 30% improvement in performance for trench excavation, earthworks and truck loading, along with a profitability of 100% or more, an attractive investment. Not to be overlooked here is the Gravis rack, which is so simply designed that site teams can quickly learn how to operate it.

“We will continue to enhance safety and efficiency on construction sites with our innovations,” said Gilles Bendaoud, Vice President Key Accounts/Remarketing Europe at Develon, noting that, in addition to Real-X, the company has also developed E-Stop and the transparent wheel loader bucket to increase site safety. “Even though there are still a few legal hurdles to overcome, we have taken another significant step towards the vision of the autonomous construction site today,” said Martin Gering, Key Account Manager GSA & EE at Develon, at the conclusion of the event marking the symbolic handover of the DX225LC-7X to KIBAG.

advancement since air cannons were first introduced by Martin Engineering over half a century ago to improve material flow through raw mills, preheaters, kiln feeds, coolers, silos, chutes and other process vessels.

Developed at Martin’s Center for Innovation in Neponset, Illinois, N2® ACI has been refined during two years of real-world trials with leading cement producers in the USA as well as Brazil, France, Turkey and the UK.

cannon fired or not. We’re helping them operate more efficiently by interpreting data from the sensors so they can improve system performance, for example by adjusting firing sequences and improving installation positioning, as well as better manage preventive maintenance. Potential problems can be identified earlier, reducing unnecessary downtime and helping maintenance teams make smart decisions to optimise their systems.”

Traditional air cannon inspection methods often require maintenance personnel to manually trigger systems while visually observing pressure gauges. However, partial nozzle blockages and performance degradation can go unnoticed for long periods, resulting in reduced effectiveness, excessive compressed air and energy consumption, and increased risk of production interruptions.

Customer trials have also demonstrated important safety benefits. By reducing the need for manual inspections and emergency cleanout procedures, the system helps minimise worker exposure to hazardous environments, confined spaces and high-temperature process areas. Reports from customer evaluations also highlighted

reductions in manual water jetting, fewer emergency interventions and improved understanding of when maintenance is genuinely required.

The system operates through wireless battery-powered nodes mounted directly to air cannons, communicating via long-range radio frequency to a single cellular gateway capable of supporting more than 1,000 sensors across a site. Because ACI operates independently of plant wi-fi or control networks, installation can typically be completed without requiring a plant shutdown.

Martin says the platform is also designed to support longterm reliability and optimisation strategies by maintaining detailed historical records for every monitored cannon, including service events, firing trends and component performance data.

Pronschinske added: “Many customers simply don’t have the time or resources to continuously monitor air cannon performance. ACI gives them actionable information automatically, helping maintenance teams focus attention where it’s actually needed to keep critical material flow systems operating reliably. By turning traditional air cannons into intelligent, connected assets, plants can move from

reactive maintenance to proactive performance management.

“ACI also gives maintenance teams early visibility into cannon performance, allowing them to identify inefficiencies, improve firing sequences and address possible problems before they impact production. The technology helps facilities operate more reliably and efficiently, while reducing wasted labour, compressed air consumption and unnecessary wear on critical equipment across demanding bulk material handling applications. Ultimately ACI helps optimise process flow, reduce costly unplanned downtime and improve workplace safety by limiting the need for manual inspections.

The N2® ACI System will be introduced throughout the Martin network over the coming months and years, with further installations already underway. Find out more at www.martin-eng.com/ content/product/22097/n2-aircannon-intelligence-system.

CONTROLS, SENSORS & LEVEL MEASUREMENT

LEVEL MEASUREMENT IN HOT STONE BINS: AN APPLICATION GUIDE Hot stone bins are a critical component of any asphalt production plant, serving as the primary storage and separation point for heated aggregate prior to mixing.

Consistent asphalt quality depends on every stage of the production process performing reliably, and that includes the level control on your hot stone bins.

When level instruments fail or give inaccurate readings, the wrong proportions of aggregate reach the mixer, and the consequences show up in every batch.

PURPOSE OF HOT STONE BINS Aggregates, including gravel, sand, and crushed rock, must meet two essential conditions before they can be incorporated into an asphalt mix: • Heated to remove residual moisture and reach the required process temperature.

• Sorted by size for precise mixing formulas.

The hot stone bin is where this heated, and sorted material is temporarily stored before moving on to the next stage in the process.

HOW A HOT STONE BIN WORKS 1. Heating the aggregates – Raw stone from the quarry is dried and heated in a rotating drum, commonly referred to as a dryer.

2. Screening by size – The hot material is elevated and passed over vibrating screens that separate it into distinct size fractions (e.g. fine sand, medium aggregate, coarse stone).

This stage is also known as the screen house.

3. Storage in bins – Each size fraction drops into its own compartment within the hot stone bin, where materials are kept both separated and at temperature.

4. Controlled release – During asphalt production, precise quantities of each aggregate size are released from the bins into a weigh hopper. This ensures that every batch of asphalt meets the exact specification required for its intended application.

Think of hot stone bins as a bank of heated storage compartments, each holding a different aggregate size fraction and always ready to be mixed in exactly the right proportions for road building and repair.

BENEFITS OF A RELIABLE HOT STONE BIN INSTALLATION • Accurate mix control – Stores different aggregate sizes separately to enable precise, repeatable batching.

• Consistent quality – Every asphalt batch is produced to the same specification.

20

Bulk Solids Today

• Temperature retention – Aggregates are maintained at the correct temperature for effective bitumen coating.

• Efficient operation – The bin acts as a buffer between continuous drying and batch mixing, smoothing out production flow.

• Process automation – Works with level instruments for reliable, fully automated control.

• Flexibility – Enables rapid changeover between different asphalt mix designs.

• Reduced waste and downtime – Minimises off-specification material and unplanned production interruptions.

CHALLENGES OF WORKING WITH HOT STONE BINS • Segregation risk – Uneven material distribution can adversely affect mix quality.

• Instrument reliability and installation – Level instruments that are incorrectly installed or configured will produce inaccurate readings, undermining process control.

• Wear and abrasion – Bins, liners, and gates are exposed to constant high-temperature wear.

• Blockages and bridging – Hot aggregate can compact or arch, disrupting material flow.

• Heat loss – Inadequate insulation reduces thermal efficiency and can compromise mix quality.

• Maintenance access – Internal components can be difficult and hazardous to service safely.

• Calibration errors – Incorrect weighing or level readings will result in off-specification asphalt.

VEGACAL 67 Capacitive high temperature probe for level measurement of bulk solids available with threaded and flange options

CONTROLS, SENSORS & LEVEL MEASUREMENT WHY CAPACITANCE PROBES FOR LEVEL CONTROL? Capacitance probes are a widely used and proven technology for level measurement and level detection in hot stone bins. Although radar has been successfully applied in many aggregate storage applications, hot stone bins often present challenges as bin shapes, restricted mounting positions etc, making capacitance measurement an attractive alternative.

The VEGACAL 67 capacitance level transmitter excels in these demanding conditions, delivering reliable level measurement with repeatable performance at process temperatures up to 400°C. It is available with both threaded and flanged process connections, offering flexible installation to suit any plant configuration.

For maximum convenience and safety, the instrument can be fitted with a head-mounted Bluetooth PLICSCOM display and adjustment module. This enables wireless access for configuration, diagnostics, and monitoring — allowing operators to manage the system efficiently without direct contact with the process.

With the VEGACAL 67 and PLICSCOM combination, you get a robust, high-precision solution designed for performance, safety, and operational efficiency.

The instrument can be mounted at either the top or bottom of each hot stone bin. Each sensor is

fitted with an isolation tube of a specified length to maintain the required clearance from the external bin wall. A flexible stainless steel cable connects the instrument to an electrode that follows the contour of the bin from top to bottom, forming an integral part of the capacitance probe assembly.

The electrode can be fabricated in various forms, such as angle iron or steel rod, depending on the application. It is secured to the bin wall using isolation brackets, typically manufactured from ceramic to provide the necessary durability and high-temperature resistance.

A range of isolation bracket types is available, and these can be supplied specifically tailored to the application for optimum performance and longevity.

At VEGA they understand that no two hot stone bin applications are identical. Contact them to organise a site visit and let one of their dedicated team of engineers assess your installation and discuss the right solution for your plant.

PACKAGING

HAVER & BOECKER CELEBRATES 20 YEARS OF ADAMS® TECHNOLOGY WITH THE ROTO-PACKER® RS Packing facilities in the cement, building materials, food and chemical industries have benefitted from HAVER & BOECKER’s ADAMS® technology for more than two decades. First introduced in 2005, ADAMS® machines use Form-Fill-Seal (FFS) technology and offer significant advantages in product protection, cleanliness and energy consumption with up to 50% less per bag compared to traditional systems. Equipped with ADAMS® technology, the ROTOPACKER® RS is the industry’s first and only rotary packing machine to offer a fully enclosed FFS packing process, resulting in minimized product loss, increased weight accuracy, optimized transport and a highly palletizable final product.

“We knew some industries — cement, building materials and pigment packing plants especially — needed a new packing option to keep their product safe and uncontaminated throughout the shipping and storage process. The development of ADAMS technology didn’t just give packing operations a highly efficient machine, it also increased the protection of their product once packing is completed.

FFS bags help ensure our customers’ product is protected and uncontaminated throughout the packing and shipping process,” said Mark Wehling, head of sales group minerals at HAVER & BOECKER. “We’re excited to introduce the ROTO-PACKER® RST featuring ADAMS® technology in light of the 20th anniversary of this advanced product.”

Many operations ship their products worldwide or go through lengthy logistics processes leading to the risk of product spills or contamination due to improperly sealed bags. The ROTO-PACKER® RS solves these challenges by cutting and welding each bag shut, which results in a fully sealed, weatherproof bag.

This process reduces film consumption, further minimizing material use, and leads to the ability to ship bags further and store them longer while minimizing product loss and maximizing profits and customer satisfaction.

The fully enclosed, compact ROTO-PACKER® RS rotary packing machine produces between 400 to 1,200 bags per hour (7-20 bags per minute) with up to 22

10 filling spouts. The compact footprint allows for easier positioning of the machine and less wasted space on the packing line. The enclosed housing of the packing machine maintains cleanliness during the filling process in powder-packing applications.

wear, resulting in increased weight accuracy and a longer machine life. Specialized dosing units and a vibration plate to provide proper deaeration and compaction create a highly efficient packing process with more product filled into a smaller bag.

For fine powder applications, the ROTO-PACKER® comes in the RST version, which is equipped with the T-Module (Turbine), a vertical impellerbased system. This system is optimized with vibrating bottles or vacuum rods to increase efficiency and provide proper deaeration throughout the packing process.

The ROTO-PACKER® also comes in the RSL, which is an air filling module that conveys product into the packaging via air pressure. The L-module is available with a fully ventilated base plate in the pressure chamber. Overall, both filling module options from HAVER & BOECKER result in over 50% less energy use than traditional filling modules.

Thanks to the redesigned, preinstalled platform, the RS features faster commissioning and shorter assembly times, leading to faster delivery. On the delivery day, HAVER & BOECKER’s service team visits the packing facility to install the ROTO-PACKER® RS and provide operator training. Adjustments can be made to meet each facility’s individual needs through the HMI, which is controlled by MEC 4.0.

Multiple customization options are available to upgrade technology on the system. New motors enhance data-driven reporting and ensure issues can be identified more precisely before they can lead to stoppages.

Updated technological options include compaction detection, patented fill-level detection during bag filling, smart ventilation and even glue edge detection for bags. Boasting a global service footprint, HAVER & BOECKER’s team serves as an ongoing consultant to the operation to ensure that filling goals are met.

The RS series integrates QUAT²RO® AI products, which use a high-definition camera and a selfprogrammed algorithm to create added user benefits.

QUAT²RO® Bag Check — ends the problem of packing the right products into the wrong bag, which is a common mistake that leads to millions of dollars in credits. The system scans the empty bag to ensure it matches the product specifications defined by the operator. If the bag that is placed onto the spout is not correct, the packer will not begin the filling process.

QUAT²RO® MatEx Check — minimizes the risks involved with bursting bags thereby increasing operator safety and eliminating countless hours of cleaning. The MATEX system uses a high-definition camera to monitor the bag as it is being filled triggering an immediate stop if a bag bursts. Unlike the standard monitoring system based on weight increase which can take several minutes to stop, this trigger shuts in down in mere seconds.

The fully enclosed ROTO-PACKER® RS rotary packing machine produces between 400 to 1,200 bags per hour (7-20 bags per minute) with up to 10 filling spouts.

The sealing process is completed with ultrasonic sealing technology, which results in a fully sealed, weather resistant and 100% recyclable bag.

Through BESPOKE, HAVER & BOECKER consults on bag selection to find the most compatible option for the operation. Their team considers the equipment and the product to create a harmonized filling process. They can also design custom packaging for their customers.

By helping to choose and design the FFS bags with specialized features — like a deaeration channel with a UFP-Perforation to help air escape the bag without losing additional product — HAVER & BOECKER helps customers present their bag as their business card, protecting the product from the elements and creating more visually appealing bags and pallets.

PACKAGING Pengelly Farms manages 1,200 acres of potato production in Cornwall, supplying approximately 16,500 tonnes of premium salad potatoes annually to UK and European customers.

AUTOMATING EFFICIENCY IN SUSTAINABLE POTATO PACKING Pengelly Farms, a long-standing Cornish potato producer, has significantly enhanced operational efficiency by integrating automated case assembly and sealing technology from Endoline Automation.

In the coastal landscape of Helston, West Cornwall, Pengelly Farms has spent over half a century perfecting its potato harvest. Established in 1967, this familyrun operation has evolved from a local grower into a premier UK producer of premium salad potatoes.

Managing 1,200 acres, they supply approximately 16,500 tonnes of produce annually to UK and European supermarkets, wholesalers and high-end restauranteurs.

However, as the Red Tractor and LEAF-accredited farm scaled its infrastructure, it encountered a classic industrial friction point: the high-speed potato packing bottleneck.

Following the recent modernisation of its processing line with a high-speed Newtec chute loader, Pengelly Farms identified an opportunity to optimise its downstream packing operations. The manual assembly and sealing of heavy 10kg boxes presented a significant operational challenge as this consistently struggled to keep pace with the upgraded system.

The traditional manual processes were no longer aligned with the performance of advanced grading and sorting technology. As a seasonal operation, Pengelly Farms recognised that increasing labour alone would not deliver the long-term efficiency gains required. Instead, they partnered with UK end-ofline packaging specialist Endoline Automation.

24

DUAL VACUUM SOLVES BOX ASSEMBLY ISSUES To transport potatoes across the UK, Ireland and mainland Europe, Pengelly Farms utilises heavy, twinwalled cardboard cases. Although these provide the structural integrity for a 10kg potato payload, they can be notoriously difficult to automate. Stiff, heavy-duty cardboard often resists opening. In a standard automated system, this can lead to bridging, tearing or recurrent machine jams.

The solution lies in the ‘dual opposing vacuum technology’ unique to Endoline. Rather than attempting to pull the box open from a single direction, the system applies force symmetrically.

“The dual opposing vacuum technology is especially beneficial when forming heavy-duty boxes.

It works by clamping each side of the case during the forming process applying the same amount of pressure to simultaneously open it from both sides,” explains UK Sales Manager James Saywell.

From a technical standpoint, this is a masterclass in using physics to bypass mechanical resistance.

Neutralising the inherent stiffness of the twinwalled card by applying equalised pressure, the compact Endoline machine eliminates the physical strain of manual manipulation.

This significantly reduces packaging waste, which supports sustainability and maintains the continuous production flow, notes Pengelly Technical Manager Ben Cavill.

PACKAGING WORKING WITH EXISTING INVESTMENTS Rather than taking a ‘scorched earth’ approach to existing infrastructure, Endoline instead treated the farm’s existing equipment as a modular tech stack.

This included maintaining brand interoperability between several equipment suppliers.

The Endoline 221 Case Erector and 613 Case Sealer were integrated into the existing packing area that already featured heavy-duty Haith multi-size graders and Tomra 3A optical sorters. The Case Erector was specifically selected for its compact footprint, allowing it to be slotted into the existing packing shed without requiring a costly facility expansion. By feeding the bottom-sealed cases directly into the Newtec chute loader using an existing conveyor, Pengelly’s achieved a seamless flow from potato grading to case filling.

“Endoline Automation was extremely accommodating.

Labour shortages meant we needed to automate this aspect of our potato packing line. But replacing our high end sorting and grading equipment was non-negotiable. Endoline worked around this. As a result, we are already exploring automating labelling and palletising with them,” comments Ben. CONSISTENT CASE SEALS Transitioning from manual assembly to the Endoline 613 Fully Automatic Case Sealer ensures that every potato case arrives with the customer in the same condition it left the Helston packing shed.

Automation provides mechanical consistency.

“Handling 10kg boxes can be an arduous task.

Manual sealing is often the first place where quality control on fresh produce packing lines slips, particularly at the end of a long shift,” highlights James.

Precision sensing governs the entire Pengelly packing process. Once the potatoes are washed and graded, they are dropped into a loading chamber.

A signal triggers when the weight is exact, and each potato case is then vibrated. This vibration is critical as it settles the product below the scoreline, ensuring the top flaps can be closed and sealed by the Endoline 613 machine without obstruction.

THE FUTURE PROOF FARM The strategic investment in automation, combined with a 2022 expansion of an 1,800-tonne cold store, has brought Pengelly Farms’ total chilled storage capacity to 10,000 tonnes. This allows the farm to manage its 16,500-tonne annual yield with unprecedented control, keeping potatoes in peak condition to ensure year-round availability.

By simplifying once-laborious tasks by automating case erection and sealing, the farm continues to shield itself from labour shortages while increasing its production capacity. “Through automation, Pengelly is ensuring we preserve our Cornish farming heritage for years to come,” concludes Ben.

Integrated into Pengelly Farms’ existing packing line, the Endoline 613 Fully Automatic Case Sealer delivers consistent case sealing while supporting increased packing throughput.

The Endoline 221 Case Erector uses dual opposing vacuum technology to reliably form heavyduty twin-walled cases, helping Pengelly Farms automate the handling of 10kg potato boxes.

SYSTEM SOLUTION FOR WASTE WOOD PROCESSING IN GERMANY “At our heating plant in Dingolfing, we utilise packaging waste wood (waste wood of classes A1 and A2) from the BMW Group plant to generate process energy. This is fed back into the plant and used there to heat the production halls. This creates an efficient cycle in which waste materials are utilised sustainably,” says Robert Heider, Managing Director of UP Energiewerke and Stadtwerke Dingolfing, regarding the UNTHA system solution.

Large quantities of waste wood are generated

daily at the BMW Group plant in Dingolfing. UP Energiewerke GmbH was seeking a high-performance and reliable solution for its utilisation. eta Energieberatung GmbH took charge of the conceptual design and technical consultancy and ultimately recommended UNTHA as the general contractor.

“UNTHA took on the planning of this turnkey complete solution for us. All components were perfectly adapted to our requirements and optimally coordinated with one another. The collaboration was very positive and characterised by flexibility and professionalism.

We can wholeheartedly recommend UNTHA.” − Stefan Hoppe, Head of District Heating and Operations Manager at the Industriestraße Heating Plant.

The centrepiece of the delivered system solution is an XR2000 with an RC cutting system. The singleshaft shredder processes waste wood efficiently and is resistant to contaminants such as nails, screws or staples.

Through the combination of the RC cutting system and a 70 mm perforated screen, around 6–7 tonnes per hour are shredded into a fraction suitable for thermal recycling (P63). Following shredding, automatic metal separation takes place via a magnetic separator, and the material is then transported via enclosed conveyor belts to the outdoor area. There, the material is temporarily stored in bunkers and fed into the waste wood boiler.

To reduce dust emissions, the shredder’s hopper has been fitted with a water spray system. An automatic fire protection system detects sparks and heat build-up and triggers extinguishing measures if necessary. A preassembled technical container with integrated control and cooling technology also significantly reduces the installation effort on site. https://www.untha.com/ Bulk Solids Today

RECYCLING & WASTE MANAGEMENT

FDA CONFIRMS: FOOD-GRADE RHDPE AND RPP USING COPERION RECYCLING TECHNOLOGY Coperion has received a Letter of No Objection (LNO) from the U.S. Food and Drug Administration (FDA) for its high-density polyethylene (HDPE) and polypropylene (PP) recycling technology. The letter confirms that the combination of Coperion twin screw extruders and EcoFresh silo degassing used in the manufacture of rHDPE and rPP fulfills the requirements for direct contact with food.

Coperion is the first provider of complete decontamination systems featuring twin screw extruders and EcoFresh silo degassing to offer the market a highly efficient solution for the production of food-grade recyclates, covering capacities from small throughputs up to 6,000kg/h. Coperion achieves the level of decontamination of rHDPE and rPP required for the LNO through the interplay of these two proven technologies. The quality of this solution was validated in a challenge test and confirmed by the FDA. This opens up new possibilities for the recycling of food packaging: For example, food-grade regranulate can be produced from HDPE milk jugs or fruit juice bottles and then reused to manufacture similar bottles or related products.

Food containers, cups, bowls and trays made of PP can be recycled into new packaging for direct contact with food.

MANUFACTURING FOOD-GRADE RHDPE AND RPP Manufacturing food-safe recyclates is one of the greatest challenges in plastics recycling. Such regranulates must be certified as suitable for direct contact with food, fulfilling the highest requirements for purity and safety.

“The FDA’s LNO means that rHDPE and rPP manufactured with our technologies can be used for new food packaging in proportions up to 100 percent”, said Stefan Lachenmayer, Global Commercial Director Recycling at Coperion. “As a result, we provide recyclers the assurance that our energy-efficient mechanical recycling process manufactures high-quality recyclate for use cases A-H. These include, for example, packaging for hightemperature, heat-sterilized, pasteurized or frozen products.”

PROCESS STEPS FOR FOOD SAFETY Significant for this Coperion system’s high decontamination performance are the co-rotating twin screw extruder’s high degassing performance and the efficient EcoFresh silo degassing system, where even low residence times are enough to reliably remove low-volatility migratory substances.

Raw material for the Coperion food-safe rHDPE recyclate process consists of used HDPE beverage bottles or their caps. The material stream for rPP compounds consists of vegetable trays, packaging, yogurt containers, and the like.

The material is fed into the extruder via Coperion K-Tron gravimetric feeders, where it is first melted, intensively mixed, homogenized and degassed using twin screws. Coperion profits from its many years of 28

experience in melt and solid devolatilization when designing process parameters and has configured both the process and the screw configuration to optimally meet the requirements of the respective recycling application.

Plastic is purified of solid foreign materials via a melt filter and then pelletized. Next the recompounds pass a second decontamination step in the newly developed and standardized EcoFresh silo degassing unit.

FOOD-GRADE TESTS AT COPERION RECYCLING INNOVATION CENTER Recyclers can test the decontamination performance of the Coperion extruder and EcoFresh at the Coperion Recycling Innovation Center where both technologies are available for extensive trails using original material streams. Together with Herbold Meckesheim’s Test Center, where grinding and cleaning of raw materials takes place, Coperion can reproduce the entire recycling process in its test centers.

“The basis for the suitability of our HDPE and PP recycling solutions for manufacturing food-contact materials lies in our integrated approach as a system provider. We look at the entire process and apply our decontamination technologies precisely at specific points in the process chain. It is their optimal interplay that makes the efficient achievement of the necessary level of decontamination possible”, says Stefan Lachenmayer. https://www.coperion.com/

RECYCLING & WASTE MANAGEMENT

EUROPEAN MANUFACTURERS FACE AUGUST 2026 PACKAGING COMPLIANCE DEADLINE AS EPR REGULATIONS TIGHTEN GLOBALLY Trioworld’s Policy to Practice webinar series highlights the near-term documentation requirements companies need to be preparing for now.

THE AUGUST 2026 DEADLINE European manufacturers have until August 2026 to complete a formal compliance assessment and hold documentation of compliance under the Packaging and Packaging Waste Regulation (PPWR). Suppliers into those manufacturers are also required to provide supporting information to enable compliance assessments to be completed.

ABOUT THE SESSION This deadline was highlighted as one of the most immediately actionable requirements facing European businesses during Trioworld’s second Policy to Practice webinar, held on 10 June 2026. The session, titled Understanding Packaging EPR Across Markets: Europe and North America, brought together Lena Lundberg, Public Affairs and Regulatory Director at Trioworld; Crystal Bayliss, Interim Executive Director of the U.S. Plastics Pact; and Drew White, Technical Product and Training Specialist at Trioworld.

PPWR AND THE CHANGING EUROPEAN LANDSCAPE Lena Lundberg outlined how PPWR is reshaping producer responsibility across the EU, including a harmonized definition of producer that will affect how companies participate in national EPR schemes, and the introduction of modulated fees based on recyclability performance and potentially recycled content inclusion.

The harmonization of the producer definition is a significant change for companies operating across multiple EU member states. Where previously a company might carry different responsibilities depending on the national system it was operating in, PPWR creates a single shared framework as the baseline.

Fee modulation under PPWR links what companies pay into EPR schemes to the recyclability grade of their packaging. In practice, several member states are already ahead of the PPWR framework on this point.

Belgium offers a fee discount for plastics containing a minimum of 10% post-consumer recycled (PCR) content for non-contact applications, or 20% PCR for contact-sensitive applications. France is introducing a bonus of between 450 and 550 EUR per ton for the use of recycled plastics in wholesale packaging from 2026, rising to 1,000 EUR per ton after 2027.

NORTH AMERICA: SEVEN STATES, NO SINGLE RULEBOOK The webinar also addressed the North American regulatory landscape, where EPR legislation has now passed in seven US states, with a further three states in study or needs-assessment phases. Crystal Bayliss, Interim Executive Director of the U.S. Plastics Pact, highlighted California’s 2032 targets as the most consequential nearterm benchmark for companies operating in the US market.

California’s legislation requires 100% recyclable or compostable plastic packaging, a 25% source reduction target for plastic packaging, and a 65% recycling rate for single-use plastic packaging, all by 2032. Transport packaging, including stretch film, is within scope.

THE PCR DEMAND GAP Bayliss raised a structural challenge facing the industry on both sides of the Atlantic. EPR legislation is driving investment in collection and sorting infrastructure, but collected material still has to be purchased and turned back into products. Several plastic film reclaimers closed in 2025 amid insufficient demand for recycled content, raising questions about whether current incentive structures are generating enough pull from manufacturers and brand owners to keep the recycling system economically viable.

California’s 65% recycling rate target cannot be met through collection alone. It requires active procurement of PCR material by the companies placing packaging on market.

TRIOWORLD’S RESPONSE Trioworld’s Loop product range contains a minimum of 30% independently verified PCR, offering customers a direct route to reducing virgin plastic content and contributing to the demand side of the recycling system.

The company’s Triocircular closed-loop service collects used stretch film from customers, processes it, and returns it as new product with verified recycled content, creating a closed loop for flexible packaging in the supply chain.
