Remanufacturing is a key value retention process that helps transition to a circular value chain by retaining the inherited value of products. However, recent studies indicate a lack of accurate and accessible information and information systems to facilitate the industrialization of remanufacturing. Information management is crucial, as accurate and accessible information must be securely gathered. This study investigates the types of information crucial to the successful industrialization of remanufacturing systems, focusing on two studies including in total four cases. The empirical findings emphasize the importance of information from the user phase, such as parts needing repair, damage alerts, and expected product life. This information is vital for planning and executing remanufacturing activities, as it helps assess the condition of returned products. Moreover, the study identifies several main challenges. Firstly, a lack of direct contact with end customers hinders the collection of information required for the remanufacturing activities. Secondly, the involvement of multiple actors in the value chain complicates tracing products back to end customers and gathering relevant information. Thirdly, high-variant, low-volume products pose challenges for remanufacturing within existing manufacturing systems, requiring reevaluation of practices and employee skills as volumes increase. Additionally, customization adds complexity to tracking, product returns, and remanufacturing, increasing costs and limiting resale potential.
