Abstract
GreenGemini is a research project focused on developing a Green Digital Twin for sustainable and data-driven manufacturing in the metalworking industry. The project enables automated, real-time assessment of environmental impacts and Product Carbon Footprints (PCF) directly within production processes by combining sensor data, Digital Twin technologies, and lifecycle assessment methods. Within this framework, gemineers leads the development of the platform to create transparent, component-specific sustainability data and support data-driven optimization of production processes.

Description
Manufacturing companies are increasingly facing rising energy costs, stricter sustainability regulations, and growing pressure to reduce their environmental impact. At the same time, new regulatory frameworks such as the Digital Product Passport (DPP) require companies to provide detailed and reliable sustainability data for their products.
GreenGemini addresses these challenges by developing a Green Digital Twin that continuously captures material, energy, and process data directly from the shopfloor. Based on this data, environmental impacts and Product Carbon Footprints (PCF) are calculated automatically and assigned to individual components in real time.
By integrating sensor-based data acquisition, automated lifecycle impact assessment, and scalable data architectures, the project enables companies to identify resource hotspots, compare production scenarios, and make informed decisions to improve sustainability, efficiency, and cost-effectiveness.
Core Innovation Areas
GreenGemini focuses on four core innovation areas that enable real-time sustainability assessment and data-driven optimization in manufacturing:
- Sensor-based Lifecycle Inventory (LCI): Real-time acquisition of material, energy, and process data using multi-sensor approaches
- Automated Lifecycle Impact Assessment (LCIA): Real-time calculation of environmental impacts and Product Carbon Footprints.
- Sustainability devision support: Comparison of production scenarios and simulation of sustainable manufacturing strategies
- User-centered visualization: Intuitive visualization and seamless integration into Digital Product Passport structures
Role of gemineers in GreenGemini
Within the project, gemineers leads the development of the Green Digital Twin platform, including the integration of shopfloor data and sensor systems, the development of data processing pipelines and Digital Twin models, the implementation of lifecycle assessment methods, and the provision of APIs and user interfaces for data-driven sustainability and decision support.
Summary
GreenGemini lays the foundation for a new generation of sustainable manufacturing by combining Digital Twin technology with automated lifecycle assessment. The project enables companies to make environmental impacts measurable, transparent, and actionable directly within production.
