Closing the City Cycle: An Approach for Defining Cross-Sectoral Circular Actions to Be Included in a Circular Urban Plan

Abstract

The topic of the circular economy and its potential applications to urban areas is currently widely discussed as it is seen as a possible solution to the state of environmental, economic, and social unsustainability resulting from the previous consumption model. However, although many contributions focus on one or more key sectors affecting the urban environment (Mobility, Waste, Built Environment, Water, Energy, and Food), few attempts address the topic comprehensively, promoting a broad vision that encompasses all sectors and evaluates their interrelation. This paper aims to meet this need by first providing an overview of the topic of circular cities, best practices, and circular actions, and subsequently defining a synergistic methodological framework of intersectoral circular actions that considers the interrelation of the various key sectors and that can be used as a tool to contribute to the overall closure of the urban cycle of a city. The city of Genoa is proposed as a case study for a first application. This research should be incorporated into a possible Urban Circular Action Plan aimed at implementing current international strategies.
