At the same time, the environment is respected. On the other hand, the Circular Economy is another recent concept where the efficient and effective use of resources and products is proposed, where the fundamental principle is the reuse of waste as far as possible and its rational use, to reduce environmental pollution, and providing economic savings for the country. This paper aims to study the relationship between the concepts of Circular Economy and Sustainable Development contextualized in the Peruvian department of Junín. To examine this relationship and its future behavior, there are challenges such as the existence of indirect relationships between these two concepts, dependent on other concepts; and relationships between concepts that are unknown, at least partially. Taking all this into account, a group of three experts on the subject in Junín was asked for their opinion to determine the relationship between the selected concepts. This allowed the representation of knowledge with the help of a Neutrosophic Cognitive Map (NCM) and the study of the dynamic behavior of concepts with the help of the Method for Hidden Patterns. 2025 2025 136 143 10.54216/IJNS.260112 https://www.americaspg.com/articleinfo/21/show/3622
