Development of sustainable cities by using circular economy: Circular cities

The world’s population growth that occurred in the last decades is one of the main reasons behind the reduction of natural resources and the increase of pollution and environmental contamination. According to this fact, the role of sustainability has become a necessity, since the future perspective of the human settlements will be characterized by an urban scenario, with the majority of the people living in the cities. Therefore, the placement of the cities in a circular economy process can be considered as an interesting and strong tool in order to identify and exploit the available resources with a consistent potential and achieve relevant benefits from them. As a consequence, a model of a sustainable city can be thought of and realized in a circular economy frame. Several studies have been done in the last decades, in order to understand how to improve the cities in this sense. In this work, inspired by the main contributions from literature in the analysis of cities as circular urban centers, we apply rigorous analysis methods to Turin, for the identification of the main indicators of circularity. The study has been completed with the fundamental contribution of a technical interview realized with an important expert in the topic of circular cities.
