Siemens Integrates IOTA for Digital Product Passports Under EU Sustainability Rules

• Siemens will use IOTA and AAS in its Digital Product Passport system to support EU ESPR traceability and sustainability records.
• Siemens’ refurbished SIRIUS soft starter cuts CO₂ emissions by up to 50% versus a new unit through lower resource use.

Siemens Smart Infrastructure is developing a Digital Product Passport architecture that combines Asset Administration Shell with IOTA-based distributed ledger technology. The framework aligns with the EU Ecodesign for Sustainable Products Regulation, which is pushing manufacturers to improve product data across the full lifecycle. 

Each industrial device will feature a QR-linked digital identity. That identity will connect users to key product information from production to maintenance, refurbishment, and end-of-life handling. The setup creates a structured record for lifecycle tracking, while also making sustainability data easier to verify.

The use of Asset Administration Shell and IOTA places the passport system within a digital structure built for industrial environments. Product history, servicing details, and refurbishment records can be attached to one traceable profile. This gives Siemens a way to connect physical equipment with digital documentation required under evolving EU sustainability rules.

At the same time, Siemens is expanding its industrial protection portfolio through the SENTRON Electronic Circuit Protection Device. The semiconductor-based device entered the market in 2024 and can switch up to 1,000 times faster than conventional systems. Faster switching helps reduce short-circuit energy and supports stronger protection for electrical infrastructure.

Previously, we covered Orobo’s deployment of Digital Product Passports on the IOTA Rebased mainnet for EU-focused product traceability. The system gives each product one verifiable digital record containing data such as origin, composition, and circularity.

Siemens Taps IOTA to Expand Traceability and Circular Product Strategy

The SENTRON range will also expand into high-voltage applications through a three-phase version designed for 400V, 32A, and 50 Hz systems. This version is intended for use in conveyor belts, elevators, heat pumps, air conditioning systems, event power distribution, and UPS installations. 

Siemens is also introducing the SIRIUS 3RW5 -Z R11 refurbished soft starter at the Light plus Building 2026 trade fair. The product follows circular economy principles through a controlled refurbishment process for used soft starters. That process cuts carbon dioxide emissions by around 50% compared with manufacturing a new unit, mainly through lower resource use.

Used devices go through detailed testing before refurbishment begins. Several critical components are replaced, and the units’ functionality is fully checked to satisfy new-device quality standards. 

The refurbishment process is documented in the Environmental Product Declarations, providing transparency into the product profile. The soft starter carries CE certification, while CCC, UL/CSA, and ATEX certifications are still pending. Therefore, Siemens is connecting compliance records and sustainability data into a single industrial framework by combining IOTA-based Digital Product Passports with circular industrial hardware.

CNF previously covered Siemens’ patent reference to IOTA as part of a system for temporal correlation and renewable energy certificate management using NFTs. The filing noted that distributed database structures, such as IOTA, can support tamper-proof and verifiable records.

Early this month, IOTA secured a listing on Bullish, giving the token access to a U.S.-based exchange focused on institutional investors. CNF noted that the listing also expanded the network’s market presence through Bullish’s operations in Hong Kong and Europe.
