eBook: Circular Economy: a new mindset on sustainable development The concept of Circular Economy, which is the central theme of this book, is based on the preservation and increase of natural capital by controlling finite stocks and balancing the flow of renewable resources. Both sustainability and Circular Economy concepts go together and share the objective of mitigating the negative externalities mentioned here. The strategies to find the possible answers go through several actions. An economic model that implies changes in the way of thinking and acting in a society requires the training of people and professionals focused on its application. The publication of this book was a way of delivering the results of this work to the society, placing its individuals as agents of social transformation. In this context, the chapters are varied purposefully, so that topics pertinent to Circular Economy can be discussed, but not consolidated in one work alone so far. If we strive for a more resilient economy, a fairer society, and a healthier environment, walking the path is needed. We hope that this reading can elucidate the subject and awaken a critical sense of what attitudes or strategies can get us started. The book aims to reach from readers specialized in the subject, professors, high school students, undergraduate and graduate students, to the curious, beginners in the world of Circular Economy and new business models.
