The Development of Remanufacturing Process Model

Abstract

This thesis investigates the optimisation of remanufacturing processes within the circular economy framework, focusing on enhancing product functionality and extending product use while minimising waste production. Central to this study is the industrial process of remanufacturing, which involves returning used products to at least their original performance level with a guarantee equivalent to that of newly manufactured products. This research is grounded in the conceptual design decisions that account for approximately 80% of the remanufacturing considerations, highlighting the significant impact of early design choices on the efficiency of remanufacturing. Using a detailed case study of the NIRS31 non-invasive road sensor provided by OTT HydroMet, the thesis captures and analyses the know-how of typical remanufacturing processes. It introduces a comprehensive remanufacturing process model that outlines structured activities and knowledge requirements at various stages, aiming to standardise procedures and enhance knowledge management across remanufacturing operations. By implementing different strategies, the study demonstrates practical applications of circular economy principles, emphasising the reduction of environmental impact and resource consumption through efficient remanufacturing practices. This research contributes to the theoretical and practical understanding of remanufacturing in a circular economy by providing a detailed model and empirical evidence of its benefits. The study proposes recommendations for integrating advanced technologies and further research into broadening the model's application across various industries to confirm the scalability and applicability to fully realise the environmental and economic potentials of remanufacturing.
