Objective: The research sought to analyze managers' perceptions about the circular economy and its relevance to organizational sustainability. Methodology: The research adopted a qualitative exploratory approach, using in-depth interviews with thirteen managers from different Brazilian industries. Data collection was conducted with recorders to ensure accuracy, and speech analysis was employed to identify patterns and meanings in managers' perceptions of the circular economy and its relationship with organizational sustainability. Results and data analysis: The results revealed a diverse understanding of the concept, emphasizing its strategic importance to promote sustainability and resource efficiency. Managers recognize the environmental and economic benefits of the circular economy, although they have highlighted challenges in its implementation, especially related to coordination and collaboration between stakeholders.

Objective: This research aimed to analyze the implications of the use of additive manufacturing for sustainability in production processes. Methodology: The research was characterized as exploratory qualitative approach, which was carried out with 15 professionals from a Brazilian industry. Data collection was conducted through in-depth interviews, and analysis of the speech revealed insights into the environmental implications of additive manufacturing. Results and discussion: As a result, it was evidenced that despite the benefits offered by additive manufacturing for sustainability, such as reducing material waste and personalized production, there are significant challenges to be faced. Concern about the recyclability of materials used in 3D printing has been identified as a critical point, underlining the pressing need to develop more efficient and sustainable recycling processes to deal with the waste generated. In addition, mentioning the importance of considering the full life cycle of products emphasizes the complexity of environmental issues associated with additive manufacturing, requiring holistic approaches that consider environmental impacts at all stages of the process. Conclusion: Therefore, the need for an integrated approach to sustainability in additive manufacturing is highlighted, which not only maximizes the environmental benefits of the technology, but also proactively deals with emerging challenges, thus ensuring a positive impact on the environment.
