This master thesis provides a thorough review and application of blockchain technology using traceability in a reverse logistics supply chain industry environment for the refurbishment of medical electronic devices. The thesis is structured in six separate sections. The first section describes the subject matter under investigation in conjunction with the current challenges in supply chain management, as well as the methodology followed for the elaboration of this thesis. The second section provides a general description of the supply chain, the purposes it serves as well as innovative technologies that are applied or are in the research stage. Emphasis is also placed on the supply chain sustainability and how this can be achieved in conjunction with the reverse logistics processes. The third section analyzes the importance of traceability in straight and reverse logistics applications of various companies, and how this contributes to addressing the weaknesses of the traditional supply chain model. The fourth section describes the architecture we apply for traceability purposes using "smart contracts" and "tokens" in the Ethereum blockchain. The fifth section analyzes the importance of refurbishing medical devices in order to reuse them, the requirements followed to achieve the refurbishment, and then applies the traceability of these requirements to reverse logistics processes for these devices. The structure and framework of the application are also described. The sixth section summarizes the methods and the technologies we have applied, and highlights their advantages, their limitations and disadvantages, along with fruitful areas for future research and improvement.
