The praised solution has been in use at Eurl Saterex-Iris in Algeria since autumn 2019. Eurl Saterex-Iris is the third biggest tyre manufacturing plant in Africa, serving both local and export markets. The modern plant was mainly designed and constructed by Black Donuts Engineering and its international partner network. Black Donuts is also responsible for production management, which applies the core principles of Lean Management and focuses on reducing the interim stocks to the bare minimum according to the pull method. To enhance this, the company developed an RFID-based electronic eKanban solution together with Toptunniste.

“The eKanban project started from a need to improve production management. The first acute challenge we met was the lack of adequate and accurate information on the overall production status,” Solution Manager Aki Nurminen recalls.

Originally, there were nine Kanban boards located all over the two-floor factory. One had to check each board manually, so it took time and effort to capture a complete view of the production status.

Another deficit concerned the insufficient information provided on manufacturing schedules. The old Kanban boards did not give enough information on when certain materials were supposed to be in production.

The returned cards included no accurate time markings, so it was hard to stay updated, notice stock alerts and to respond on time.

Real-time production status

New technology was needed to solve the problem. It became clear that initiating remote monitoring would require electronic boards instead of the traditional ones. Black Donuts contacted another Finnish technology company, Toptunniste, to present the idea and search for a way to actualise it. The solution was simple: adding RFID features to an existing Kanban board would upgrade it to a more accurate, more informative, and easy-to-use eKanban board. Next, the old cards were replaced by RFID tagged cards, readable through RFID technology.

Now, all nine eKanban boards are online in Saterex’s internal data system and easily monitored from any computer. Consequently, an up-to-date overall view of the entire production is now always at hand.

The eKanban solution enables better and real-time tracking of overall production status and enhances the supervision of production processes.

It adds the time markings automatically to each card on return, keeps account, and establishes automatic triggers to replenish stock when predefined minimums are reached for each inventory item.

The system also calculates and presents the estimated time left before reaching the pre-defined minimum of each item in the downstream processes. This is the lens that helps us prioritize and schedule the production runs.

Optimised processes

The new eKanban boards were taken into use at Saterex tyre plant in fall 2019. For the users operating in the production lines, the new solution has not brought any changes in their daily routines, but the Kanban boards are used the same way as before. For the supervisors and factory management, the new system enables a remote and real-time view of the production status through a web interface.

The new solution helps in prioritizing the tasks and shortens the reaction time to different problems arising in production. eKanban is also a great planning tool, as it gives us a complete process overview, Aki explains.

The eKanban system gets all the production information it needs straight from the company’s MES, where the daily consumption levels of each process, as well as the minimum and maximum storage levels, are defined. Separate eKanban views, visualizing the interim storage levels, can be reviewed through MES which enables effective inventory management.

The eKanban solution is designed for tracking the production, not to automatically assign anything. It is always the team, the people, who make the decisions based on the information they receive. However, the solution helps to improve tracking and optimizing operations, Aki says.

Advanced work management

Moreover, the eKanban solution enhances work management.

Compared to manual Kanban systems, eKanban gives additional information on storage unit rotations, events and even stock rotation history. It is valuable information for both follow-ups and for managing transportation activities and best working methods. Earlier, the material transportation could idle, and the return of cards to the Kanban boards be irregular, which caused various scheduling challenges, stockouts and unexpected changes in demand.

It was nearly impossible to find the root cause for problems and consequently improve it. Thanks to the digitised solution, we can now track every event, which supports work development and feedback giving.

While the manual Kanban boards already gave a good boost for companies in optimizing production, the new eKanban solution brings monitoring, tracking and optimizing to a remarkably higher level.

eKanban is an excellent example of how we can improve proven old methods during digital transformation.

eKanban was designed to add a remarkable value to the supply chain support operations. This was accomplished by optimizing cost-effectiveness, efficiency, and the movement of materials. Currently, Aki’s team is already developing the next generation eKanban solution, one without any physical cards or printed labels and boards. This will serve the needs of the highest automation solutions, which require visual identification instead of manual labelling or printed cards.

The operators do not even need to touch the storage units anymore, but the Electronic Shelf Label (ESL) completes the visual identification. Electronic Shelf Label is automatically updated during the manufacturing processes and events referring to RFID identifications and data communication. This way, the labels are never missing, old or wrong, and they are readable in all occasions and all the time, Aki explains.

Tyres Europe and the Association of Synthetic Amorphous Silica Producers (ASASP) have released a joint position paper on synthetic amorphous silica (SAS) in tyre manufacturing. The document highlights SAS as a critical component that improves wet grip, reduces rolling resistance and supports durability, thereby enhancing vehicle safety, fuel efficiency, electric vehicle range and lowering use-phase emissions.

A proposed harmonised classification for SAS is under consideration. Though not an outright ban, the industry warns it would likely compel manufacturers to phase out SAS during design rather than manage exposure, effectively bypassing practical risk controls.

Tyres Europe and ASASP urge regulators to base any action on robust evaluation of SAS properties, exposure conditions, established industrial uses and broader socio-economic impacts on European value chains. Policy measures must reflect these factors to avoid unintended disruptions.

Tegeta Green Planet participated in the recent Social Design Days conference, a three-day event hosted by the Design Institute that centred on circular design and sustainable innovation. The gathering brought together diverse professionals to explore the intersection of creative disciplines and environmental responsibility.

During the proceedings, Tegeta Green Planet Director Shalva Akhvlediani engaged in a panel discussion that examined Georgia’s trajectory in building a circular economy. The conversation addressed the nation’s current obstacles and prospective avenues for growth, with a particular focus on systemic shifts in resource management and regulatory frameworks.

Akhvlediani pointed to measurable advancements in Georgia’s waste management infrastructure, the adoption of Extended Producer Responsibility standards and a growing national recycling ethos. These developments, he observed, are creating a robust base for more judicious resource utilisation and fostering habits of conscientious consumption. The panel further acknowledged that resourcefulness is deeply rooted in Georgian heritage, where mending, reusing and bequeathing goods were traditional practices, though modern consumerism has eroded these customs, necessitating a blend of age-old wisdom with contemporary circular strategies.

A critical takeaway from the discussion was the assertion that technological fixes and legislation alone are insufficient. Genuine progress, Akhvlediani argued, hinges on synergistic cooperation between designers, architects, researchers and creatives to engineer products and systems that prioritise longevity and recyclability from inception. Social Design Days proved instrumental in facilitating cross-sectoral dialogue, promoting circular principles and inspiring actionable solutions for national sustainability. Tegeta Green Planet reaffirmed its dedication to advancing these environmental objectives and supporting collaborative platforms that drive meaningful change.

Continental is set to construct its first company-owned wind farm adjacent to its tyre production facility in Korbach, within the municipality of Twistetal, Hesse. The initiative will supply electricity directly to the plant, situated roughly eight kilometres away, thereby diversifying the manufacturer's energy portfolio. This strategic move aims to accelerate renewable power adoption, enhance cost competitiveness and diminish reliance on volatile energy markets.

The project features three turbines that, alongside existing solar systems, are projected to satisfy approximately two-thirds of the Korbach plant's electricity requirements. With an annual generating capacity of around 55 gigawatt-hours, the turbines could supply roughly 15,000 average households. Continental has allocated a mid-double-digit million-euro investment, having secured all necessary permits. Groundbreaking is anticipated in 2026, with commissioning expected about 18 months later.

Tyre production consumes significant power for operations like mixing raw rubber and extruding components. The Twistetal wind farm will enable the Korbach plant to meet a larger proportion of demand with locally sourced renewable energy fed directly into manufacturing. This addition complements existing infrastructure while maintaining reliable operations during fluctuating wind or solar conditions. The Korbach facility, employing approximately 2,400 people, produces tyres for passenger cars, motorcycles, bicycles and industrial uses.

The selected Nordex N175/6.X turbines have a hub height of 179 metres and a rotor diameter of 175 metres, reaching a total height of 267 metres, making them among the most powerful onshore turbines available.

The Korbach project represents a key step in Continental's broader strategy to expand proprietary energy generation, with similar initiatives considered globally. The goal is a flexible, economically viable energy supply while increasing renewable power proportion, ideally produced near each manufacturing site.

Continental is evaluating feasibility at worldwide plants, considering local conditions, regulations, storage, integration with existing sources and financial viability. Since 2020, the firm has covered global purchased electricity demand with renewables and reduced tyre production greenhouse gas emissions by approximately 180,000 metric tonnes over four years. By early 2026, coal and heavy fuel oil were eliminated at all production sites, replaced by electricity from renewables, biomass, biogas, LPG and natural gas for steam and heating.

Dr Bernhard Trilken, Head of Manufacturing & Logistics in Continental’s Tires group sector, said, “Having our own wind turbines near the plant will give us more predictable energy costs and reduce our exposure to volatile energy markets – key factors for competitive tyre production in Germany. This is fully aligned with our global strategy to expand our own renewable energy generation and will serve as a blueprint for other sites worldwide.”

Klaus Ohlwein, head of the Continental tyre plant in Korbach, said, “The wind farm will bring major benefits to our location. It will help us cover a significant share of our electricity needs in Korbach with our own renewable sources at competitive and more predictable costs. The electricity generated will be used directly in tyre production, including in mixers and extruders. The project is an important step in our sustainability activities at the site and demonstrates how industrial competitiveness and sustainable energy use can be effectively combined in Germany.”

Pirelli is set to play a central role as the FIM Superbike World Championship concludes the first half of its season this weekend at Donington Park for the UK Round. Marking the final event before the summer break, the Italian tyre manufacturer has equipped competitors with the softest rear compounds from its 2026 standard range. This selection represents a clear advancement in development from the previous year, when riders were limited exclusively to older specification tyres.

For the premier WorldSBK class, the rear tyre allocation is headlined by the SCQ extrasoft compound, intended primarily for qualifying and the Superpole Race. This option, the softest in Pirelli’s portfolio, has already garnered positive feedback from riders during the Emilia-Romagna Round for its exceptional single-lap pace and consistent performance over a sprint distance. Complementing the SCQ are the SCX supersoft and SC0 soft compounds, while front tyre duties are covered by the standard SC1 soft and SC2 medium solutions, with the softer front being the overwhelming preference of last year’s grid, including triple race winner Toprak Razgatlıoğlu.

The notoriously unpredictable British weather remains a critical variable, with cool morning temperatures and frequent rain showers posing significant challenges for teams. Pirelli’s range has historically demonstrated considerable adaptability across fluctuating track and air temperatures, maintaining reliable grip in both cooler and warmer conditions. To address potential precipitation, the allocation is supplemented by DIABLO Wet intermediate and full DIABLO Rain tyres for both front and rear positions, ensuring competitors have viable options regardless of the elements.

In the supporting categories, WorldSSP riders will retain the SCX and SC0 rear compounds alongside the SC1 and SC2 front options. Meanwhile, the WorldWCR field and the emerging talents of the Yamaha R3 World Cup will also be in action, with both series utilising the Pirelli DIABLO Superbike SC1 tyre on both axles throughout the weekend’s racing programme.

Giorgio Barbier, Pirelli Motorcycle Racing Director, said, “Donington Park is a very distinctive circuit and, in many respects, a unique venue on the FIM Superbike World Championship calendar. The opening part of the lap features a series of fast, flowing corners taken at high speed and rapid changes of direction that require riders to manage significant power while the bike is still heavily leaned over. This demands tyres capable of delivering outstanding grip, precision and stability while maintaining consistent performance over race distance.

"Compared with last year, when only standard range solutions were available and no development specifications were included, this season, while confirming the same compounds introduced in 2025, we will provide riders with the complete 2026 standard range. The SCQ extrasoft compound will be the softest option in the allocation and can be used not only in free practice and qualifying but also, potentially, in the Superpole Race. For the longer races, riders will be able to rely on the SCX supersoft and, should temperatures be lower, the SC0 soft compound – solutions that have already demonstrated throughout the season an excellent balance between outright performance and consistency, as reflected by the many new records that have been set.

"Finally, the weather, which has historically been unpredictable in the UK, will once again be a key factor. Rain and low temperatures, even in the middle of summer, can have a major influence on tyre management and race strategies. Having a complete and versatile range available will therefore be essential to provide the best possible support in any weather conditions.”
