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 Retail Operations (BSRO), a subsidiary of Bridgestone Americas, has concluded its fourth annual ‘Download the App, Plant a Tree’ campaign, resulting in nearly 59,000 new trees being planted across United States. The initiative, which ran from Earth Day on 22 April through the end of Bridgestone’s Sustainable Business Week on 12 May, encouraged customers of Firestone Complete Auto Care and Tires Plus to transition away from paper-based processes. In partnership with The Nature Conservancy, the company committed to planting one tree seedling for every new download of its mobile applications.

Since the programme’s inception in 2023, the cumulative effort has contributed over 244,000 tree seedlings to a conservation project spanning 3,600 acres. For the second consecutive year, Bridgestone has collaborated with The Nature Conservancy to focus reforestation on flood-prone areas within the Mississippi Delta region, protecting vulnerable farmland. This work builds upon a significant prior contribution, as the company donated over 5,700 acres of Tennessee land to the organisation in 2018, the largest land donation in that chapter’s history.

The mobile applications function as digital glove boxes, enabling customers to schedule appointments, access vehicle histories and review promotional offers. By incentivising digital adoption, BSRO seeks to curtail paper waste across its 2,200 retail locations. Beyond reducing paper consumption, the company’s sustainability strategy incorporates electric vehicle maintenance and charging services, alongside recycling nearly all products and byproducts used in stores.

This reforestation effort supports the Bridgestone E8 Commitment, a framework of eight corporate values guiding sustainability objectives. The campaign exemplifies the company’s dedication to Energy, Ecology and Efficiency, demonstrating how customer engagement drives environmental outcomes. Through these actions, BSRO integrates ecological responsibility into its retail operations and long-term business model.

Marko Ibrahim, President, BSRO, said, “We are proud to see this campaign continue to grow and support Bridgestone’s long-term sustainability goals. By helping expand green space in communities across the country, our stores are demonstrating what it means to live out our Promise to Care.”
