Siemens AG Xetra: SIE

Industrial technology, electrification, buildings, grids, mobility and healthcare

SIE
Public materials brief.

Siemens has a concrete circularity case inside electrical infrastructure. It reports that a switchgear retrofit can extend operating life by up to 15 years while reducing material use by up to 80% versus new equipment. That is the right standard for this brief: a named product, a performance baseline, a service decision and a recovery route, not a company-wide circularity narrative.

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.

Material inputs to resolve

  • 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

Siemens has a concrete circularity case inside electrical infrastructure. It reports that a switchgear retrofit can extend operating life by up to 15 years while reducing material use by up to 80% versus new equipment. That is the right standard for this brief: a named product, a performance baseline, a service decision and a recovery route, not a company-wide circularity narrative. 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.
