SUMMARY:

The current linear economy model, where there is a constant resources extraction and disposal, results in negative impacts to all urban sustainability dimensions. The circular economy opposes this model through the implementation of strategies that aim to contribute to increasing the life cycle of materials and products. Considering that most of the resources are consumed and discarded inside the cities, this thesis question is “does the transition to a circular city contribute positively to urban sustainability?”. In this context, the main objective was to identify the feasibility of implementing the transition to a circular city and its contribution to urban sustainability. Methodologically, it is a qualitative and descriptive research that was organized in four stages: i) literature review about circular economy and urban metabolism (chapters one and two), it was applied integrative review and bibliometric analysis; ii) literature review about circular city and its connections with seven other sustainable urban typologies (chapter three), a narrative review was applied; iii) identification of the circular city transition requirements, Amsterdam/Holland was used as an example of the transition process (chapter four), institutional reports were used in this chapter; and iv) demonstrate that the circular city transition requirements may be structured in two ways: circularity clusters or city networks (chapter five), the Brazilian aluminum recycling was the example used in this chapter that was methodology based on reports and institutional websites research. This thesis demonstrates that the circular city transition requirements may be organized in a framework with science and technology base, structural conditions, governance, and transition dynamo. It was also demonstrated that this requirements framework may be applied in circularity clusters and in city networks. Circularity clusters are indicated for a city or a group of nearby cities that have the necessary resources for the implementation of a certain transition strategy. When the city or region does not have all the necessary structure for the implementation of a strategy, it is recommended a networks of cities organization, but it must consider technological and logistical costs. The higher the number of transition programs, the higher the transition level. It is also considered that the circular city transition occurs inside a spiral with increasing transition levels. The circular city transition quality and the transition spiral size depend on the city structure. This structure demands public policies for the circular city transition. Thus, it is concluded that eh circular city transition is possible, and that the application of circular economy principles in the city contributes to urban sustainability in the social, environmental, and economic dimensions.
