Data for Multi‑Criteria Assessment: A Case Study Integrating Eco‑design Principles in Sustainable Manufacturing

This data set was applied to the study published under the titled "Multi‑Criteria Assessment: A Case Study IntegratingEco‑design Principles in Sustainable Manufacturing". The study integrates Eco‑design principles and the Life Cycle approach in an MCA toevaluate the sustainability performance of manufacturing routes.The assessment is appliedto conventional production across five use cases involving complex geometry parts.The aim is to evaluate areas of material criticality, environmental impacts, chemical risks,as well as social aspects, including gender dimensions (C‑MET‑ESG). Outcomes are synthesisedinto colour‑coded hotspot tables and Eco‑design recommendations. Key findingshighlight opportunities such as substituting high‑criticality alloys, increasing material efficiency,and promoting gender inclusive workplace practices. Technological transitionsfrom CNC machining and hazardous post‑processing to laser and additive manufacturingfurther enhance safety, resource efficiency, and resilience. The novelty of this study liesin the integration of LCA principles, the C‑MET‑ESG matrix, and CRA‑SSbD guidelineswithin an MCA, establishing a hazard‑aware, socially inclusive, and technically robustframework. This approach provides life cycle linked evidence that connects early designchoices to sustainability outcomes. Furthermore, the study offers a transferable methodologyfor sustainable manufacturing in both established and emerging technologies.
