For many companies, entering the field of circular value creation is a major challenge. They have difficulty in effectively assessing and quantifying the suitability and profitability of their products for remanufacturing and related strategies, which hinders their ability to make strategic decisions and implement necessary improvements. This work therefore proposes a comprehensive set of evaluation criteria to effectively quantify the suitability and profitability of products for remanufacturing and related circular economy strategies and to compare these within the product portfolio. These criteria focus on assessing the remanufacturability of various mechatronic products and evaluating their economic, ecological, and social sustainability. For easy and efficient assessment, a tool has been built that evaluates all criteria and product characteristics and provides recommendations for product improvement. With a remanufacturing score, the application makes it easy to analyse many products and compare their suitability. Additional options, such as the upgradeability of remanufactured products and the integration of remanufactured components into new production, can be used to investigate ways of increasing profitability. This research shows differences in sustainability and remanufacturability across different companies and product-specific potentials for improvement. The application provides companies with a simple assessment of their product's remanufacturing suitability and specific suggestions for improving efficiency.
