Enhancing Circular Practices in the Automotive Manufacturing Industry - Exploring Opportunities and Challenges of Remanufacturing Electronic Control Units (ECUs)

Abstract: This thesis examines the transition to a circular economy in the Swedish automotive manufacturing industry, with a specific focus on the implementation of remanufacturing for Electronic Control Units (ECUs). The study aims to identify opportunities and challenges associated with remanufacturing ECUs by considering product characteristics, strategic and business aspects, and the industrial and regulatory environment. A qualitative case study approach is adopted, focusing on Company A, a manufacturer operating in the Swedish automotive sector. Interviews with professionals from the organization are conducted, and their responses are thematically analyzed. The findings of the study highlight several opportunities for remanufacturing ECUs, including the high quality of components, increased demand for ECUs, sustainability benefits, cost savings, and compliance with regulations and industry trends. However, the analysis also reveals various challenges, such as the complexity and sensitivity of ECUs, diagnostic processes, cybersecurity requirements, quality risks, low customer acceptance, and stringent industrial and regulatory barriers. Notably, the study emphasizes the opportunities associated with the characteristics of ECUs, providing a more balanced perspective compared to the literature review's predominantly challenging scenario. Still, the significant barriers posed by the industrial and regulatory context may hinder the successful implementation of remanufacturing systems. The insights provided by this study have practical implications for automotive manufacturers in Sweden, offering guidance for their strategic approach to circular practices, particularly in the context of remanufacturing ECUs. By addressing the identified challenges and capitalizing on the opportunities, manufacturers can pave the way towards a more sustainable future.
