Digital platforms can revolutionize sustainability within the steel industry’s value chain. Learn about the demonstrators developed in the Digitala Stambanan project.

The Digitala Stambanan Production project has worked on different value chains. One of the value chains has focused on the steel industry. It has involved one company supplying steel, another company providing C-items, such as screws and nuts, which are delivered to a third company for machining, welding, painting, and assembling products for the automotive industry.

The work has focused on improving logistics flows, ensuring delivery reliability, and enhancing traceability for products and materials throughout the value chain.

Four focus areas were identified for mapping the maturity level of the value chain and explore possible technical solutions:

  1. Product data
  2. Delivery assurance
  3. Customer knowledge
  4. Green conversion

Two of these areas resulted in demonstrators – one showcasing the possibilities of digital platforms for the green conversion focus area and another focusing on delivery reliability. The two technology providers in the project have contributed their platforms to enable the development of these solutions.

Opportunities of digital platforms for sustainability

The first demonstrator uses ChainTraced’s platform, which focuses on traceability and carbon footprint visualisation throughout the value chain. With this solution, all companies in the value chain can visualize their carbon emissions, including Scope 1, 2, and 3 (See Figure 1). The platform’s “Traceback view” displays a tree structure where information about all components and their total climate impact can be traced (see Figure 2).

One of the central values of this solution is that the final product can be labeled with a stamp showing its environmental footprint throughout the manufacturing process. This helps companies identify where the most significant climate impact occurs in the value chain and promotes collaborations to reduce these emissions.

Challenges and future steps

The first version of the green coversion demonstrator used historical data and estimates to test the communication between companies in the value chain. CO2 data has been sent at the product level and is updated twice a year. The next step could involve collecting more realistic data at the batch level and for more material types.

A significant challenge is ensuring smooth integration between companies’ internal systems and the demonstrator. Additionally, physical and digital traceability must be synchronized throughout the value chain, which requires increased automation and coordination between different systems, including operational systems (OT) and business systems (IT).

One of the main values ​​of this solution is that the final product can be labeled with a stamp that shows its environmental footprint throughout the manufacturing process. This helps companies identify where in the value chain the greatest climate impact occurs and promotes collaboration to reduce these emissions.

The members of our work package have tried to leverage data along the value chain and create clear visualizations where carbon footprints and products’ status can be viewed effectively. This work has never been more relevant with new directives for sustainability reporting (CSRD) and increased customer demands for green steel.

Article series in the fall of 2024

After several years of successful collaboration, we look forward to sharing this knowledge. During the fall, we will publish articles highlighting the challenges of digitalization in the industry, how we see that companies can address and benefit from technological development, and what we have achieved through the project. We will also emphasize the strength of this innovation collaboration and share participants’ experiences and insights.

We hope these articles will inspire more companies to embrace the opportunities of digitalization and understand the importance of collaboration for a future competitive Swedish industry.
