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.

Bridgestone has introduced a new addition to its Potenza ultra-high-performance line: the RE-71RZ extreme summer tyre. Designed specifically for grassroots racing, this tyre succeeds the acclaimed RE-71RS model. It aims to deliver quicker lap times and sharp, responsive handling, empowering drivers to maximise their performance on the circuit. A cornerstone of its design is the incorporation of ENLITEN technology, Bridgestone's next-generation platform focused on enhancing durability and advancing sustainable product design.

The tyre's development directly targets key performance metrics. On-track testing at Japan's Tsukuba Circuit demonstrated significant improvements, with the RE-71RZ achieving lap times approximately three-quarters of a second faster than its predecessor in both dry and wet conditions. This gain is attributed to several advanced engineering features. A new high-grip rubber compound, developed using insights from motorsports and proprietary NanoPro-Tech, enhances traction at a molecular level. The tread pattern has been redesigned with a stiffer construction and a larger outside shoulder to improve grip and stability, while a strategically placed main groove on the inside edge helps suppress uneven wear for longer track life. Furthermore, Bridgestone utilised its unique ULTIMAT EYE digital modelling tool to optimise the tyre's structure, creating a more uniform contact area for superior cornering grip.

Professional drivers Masahiro Sasaki and Yuji Tachikawa provided critical feedback during development, their expertise helping to refine the tyre's track-focused characteristics. The Potenza RE-71RZ builds upon a legacy that began in 1979, crafted for enthusiasts who demand competition-ready performance that transitions from daily driving to weekend motorsports. It has been approved for competition use by the Sports Car Club of America (SCCA) and will be eligible for Solo and Time Trials events starting in 2026. The tyre will be offered in 45 sizes and is scheduled to launch in the North American market on 31 December 2025.

Sasaki said, “As its strong point, the Potenza RE-71RZ achieves a high level of performance in both grip and controllability. It delivers improved dry and wet performance for street use while also achieving faster lap times and better wear resistance on the track. This tyre delivers high performance in various situations, making it enjoyable and easy to handle for both everyday driving and track use.”

Tachikawa said, “This tyre is designed for easy handling, allowing anyone to experience precise control along with excellent grip. The tyre is focused on quick warm-up for immediate, high-grip performance as well as reliable wet grip, resulting in a well-balanced tyre suitable for various driving conditions.”
