The construction industry is responsible for approximately one-third of greenhouse gas emissions and over 50% of natural resource consumption. In this context, the Circular Economy (CE) emerges as a strategy to promote economic development while reducing dependency on natural resources. Tools such as the Materials Passport (MP) are crucial in facilitating this transition. The MP is a digital solution that collects data on materials, aiming to facilitate their recovery and reuse. In Brazil, it is still underutilized. Therefore, understanding the perceptions of Brazilian professionals regarding this tool is crucial for its broader implementation in the sector. This study analyzes the views of four professionals on the concept and process of modeling an MP, based on interviews. The interviews consist of a validation method defined as a functional test, which examines the desired parameters from the user's perspective without requiring the user to understand the system's internal structure. The results highlight two main obstacles. First, modeling processes and information management still need to evolve to achieve market applicability. Second, tools applicable to CE in construction, such as the MP, must be accompanied by greater awareness of CE, MP, and sustainability concepts within the sector.
