Casa Siemens is the Italian headquarters of Siemens, a global leader in technology and innovation. The Italian site has chosen to integrate environmental sustainability into its operational strategy, focusing on responsible and circular management of material and waste flows — in line with the Group's global sustainability commitments.
The context
Casa Siemens generated several waste flows within its corporate perimeter, but lacked a structured system for tracking them precisely, assessing the actual recovery rate and identifying circular valorisation opportunities. Ordinary waste management was not sufficient: what was needed was an in-depth analysis capable of mapping material flows, reporting the emissions associated with waste transport and treatment, and defining best practices for increasing material recovery and reducing overall environmental impact.
The objectives
To precisely track the waste flows generated by the company, analyse end-of-life management, calculate associated emissions and define a Carbon Management model compliant with the UNI ISO 14064-1 standard — with the aim of increasing the recovery rate and reducing both emissions and disposal costs.
Circularity's intervention
Circularity developed a Circular Material Management project articulated across four phases:
Waste flow mapping
A detailed documentary analysis was conducted of all materials generated within the corporate perimeter, tracking each flow from sorting and collection through to transport and delivery to treatment facilities. A granular mapping that provided Casa Siemens with a complete and structured view of its waste management.
Emissions reporting
Greenhouse gas emissions associated with the transport and valorisation or disposal processes of each flow were calculated, building an overall emissions balance compliant with the UNI ISO 14064-1 standard. The analysis provided the quantitative foundation for assessing current performance and identifying the most effective improvement levers.
Identification of circular opportunities
Building on the mapping, target flows for circular economy processes were identified, with a specific focus on closed-loop valorisation — returning materials to the original production cycle — and open-loop valorisation, redirecting them towards new use chains.
UNI ISO 14064-1 certification support
Circularity supported Casa Siemens throughout the entire UNI ISO 14064-1 certification process, accompanying the company team in audit preparation and in the implementation of the Carbon Management policies needed to credibly communicate its environmental sustainability commitment. The process was supported by the integration of Circularity's industrial symbiosis platform, which facilitated the management, reporting and verification of GHG emissions data.
We also integrated a digital system, such as the Industrial Symbiosis Platform, to facilitate the management, reporting and verification of data related to GHG emissions.
The results
Casa Siemens now has a structured material flow tracking system, with complete visibility over waste management and associated emissions. The Material Management model has enabled the company to evaluate alternative valorisation processes compared to current management practices, plan a reliable increase in the material recovery rate and proportionally reduce emissions and disposal costs. The UNI ISO 14064-1 certification obtained at the end of the process guarantees credibility and verifiability towards all stakeholders, consolidating Casa Siemens' positioning as a sustainability reference point in the Italian corporate landscape.
