Material inputs to resolve
Industrial technology, electrification, buildings, grids, mobility and healthcare
Siemens reported EUR 78.9 billion in fiscal 2025 revenue. Smart Infrastructure reported EUR 23.0 billion in revenue and a EUR 19 billion order backlog at September 30, 2025. Company disclosures describe circular product design, secondary-material use, lifecycle extension and customer-circularity tools. Public sources do not establish a single product BOM, recovered-material allocation or named downstream buyer.

EUR 19B Smart Infrastructure order backlog
Evidence Product-level material loop needs qualification
- Copper, aluminum, steel, engineering plastics and electronics in switchgear, controls and building systems
- Digital components, sensors and power electronics
- Packaging, service parts and returned equipment
Outputs and residuals to resolve
- Grid control, power distribution, switching, building automation and energy-management systems
- Retired electrical equipment and service-return streams
- Recovery, reuse and secondary-material allocation are not disclosed as one product-level mass balance
First decision: Choose one Smart Infrastructure product family and one customer lifecycle. Request the BOM, material declarations, service-return pathway, replacement interval and recovered-material accounting before making a circularity claim.
Control
Siemens AG is the public parent across industry, infrastructure, mobility and healthcare.
Operating wedge
Smart Infrastructure spans buildings, electrification, grids, automation, power distribution and energy management.
Circularity evidence
Siemens describes three levers: circular products, circular business and customer circularity. Its FY25 reporting says 67% of its relevant portfolio was covered by Robust Eco Design. Its FY25 reporting says 67% of its relevant portfolio was covered by Robust Eco Design.
Evidence boundary
The company-level direction is clear. A product-level material flow, recovery route and buyer specification remain open.
Decision boundary
The public record supports one bounded next move: Choose one Smart Infrastructure product family and one customer lifecycle. Request the BOM, material declarations, service-return pathway, replacement interval and recovered-material accounting before making a circularity claim. It does not establish a buyer, commercial approval or supply agreement.
Material flow map
| Material or stream | Qualification gate | Process or destination | Evidence still needed |
|---|---|---|---|
| Copper, aluminum and steel | Grade, recycled content, safety and performance | Electrical product BOM | Supplier, mass balance and test evidence |
| Returned equipment | Asset identity and condition | Service, refurbishment or recovery | Take-back volume, routing and yield |
| Electronics and plastics | Substance, durability and end-of-life rules | Control or building system | Material declaration and recovery pathway |
This is a public screening map. It separates company-disclosed flows from open qualification work. It does not convert a destination into a buyer or an announced ambition into operating capacity.
Three defensible entry lanes
Prove circularity in one electrical product family
The product must carry the story through a BOM, a performance test and a recovery route.
Next evidence: Select a product, site, supplier set and end-of-life pathway.
Connect service data to material value
Lifecycle extension can keep equipment in use. Siemens gives switchgear retrofit as a public example, but service records still need to identify what can be repaired, upgraded or recovered.
Next evidence: Map serial-level service events, replacement parts and disposition rules.
Build a customer-facing circularity map
Smart Infrastructure serves grids, buildings and industry. A named installation creates a credible first case.
Next evidence: Choose one site and show input materials, installed asset, maintenance, upgrade and recovery decisions.

Source hierarchy: filings and company disclosures first. The brief states what those sources support and leaves the unresolved plant, grade, permit, buyer and mass-balance questions explicit.
Material Transition editorial interpretation
Siemens is already selling the digital and electrical infrastructure that makes a more resource-efficient physical economy possible. The useful question is where one product line can prove the material loop, not whether the company has a circularity narrative. The next useful working session starts with: Choose one Smart Infrastructure product family and one customer lifecycle. Request the BOM, material declarations, service-return pathway, replacement interval and recovered-material accounting before making a circularity claim.
