This thesis examines the pressing environmental issue stemming from the accumulation of Waste Electrical and Electronic Equipment (WEEE), particularly within the automotive sector. Despite directives from the European Commission aiming to promote a circular economy, challenges persist in effectively managing WEEE, particularly in End-of-Life Vehicles (ELVs). Current dismantling practices often lead to the loss of valuable materials, exacerbating environmental and health risks. Recognizing the need for improved data sharing, this research investigates the potential of the International Data Spaces (IDS) initiative in enhancing WEEE management within the automotive industry, with a focus on ELV dismantling. The primary research question centers on how IDS can facilitate WEEE information exchange between manufacturers and dismantlers within the automotive sector. The study is structured into five phases to comprehensively address this question: Exploratory Phase: This phase identifies current barriers to WEEE information sharing in the automotive industry, employing the Circular Economy (CE) monitoring framework for analysis. Requirements Elicitation Phase: Through desk research, legislative analysis, and stakeholder interviews, essential requirements for effective information sharing are identified, considering barriers, legislative mandates, and dismantlers' perspectives. Application Phase: The feasibility of meeting identified requirements using IDS is explored, drawing on academic literature and documentation from the IDS initiative. Concluding Phase: Findings from previous stages are integrated to address the main research question regarding IDS's role in facilitating WEEE information sharing. Discussion Phase: The final phase evaluates the research approach, discusses conclusions, limitations, and suggests avenues for future research. Barriers to WEEE information sharing within the automotive industry encompass incomplete documentation, lack of harmonization, information gaps, inconsistent data entry, and restricted accessibility. These findings inform the elicitation of requirements, emphasizing the need for detailed dismantling information, interoperability, and user-friendly interfaces. Evaluation of IDS demonstrates its potential in providing dismantlers access to fundamental information, simplifying data access processes, ensuring data sovereignty, facilitating interoperability, and supporting initiatives like the circularity vehicle passport. However, its effectiveness relies on stakeholder participation and regulatory support. In conclusion, this thesis proposes IDS as a solution to enhance WEEE information sharing in the automotive industry, contributing to sustainable development and advancing scientific understanding. Further research is recommended to address implementation challenges and develop specific ontologies tailored to the automotive sector.
