A Multidimensional Evaluation for Regenerative Strategies: Towards a Circular City-Port Model Implementation

The Metropolitan City of Naples represents the experimentation context of a Circular Economy Model, to verify the potential that the city-port system can make explicit and operative the principles of a type of economy that identifies new and innovative waste resources development opportunities. The principles and tools of the Circular Economy require an appropriate declination and interpretation for the specific context and highlight how the waste resources can be identified not only among the environmental ones but also among the cultural and social ones. At the same time, it is relevant to understand how it is possible to identify in the urban and territorial regeneration processes a selection of actions, which can activate, promote and consolidate circular, synergic and symbiotic processes. Through the implementation of the approaches and techniques of Multi-Criteria Decision Analysis (MCDA), it was possible to analyse two regeneration scenarios and select the actions recognised as priorities, to make operational the Circular Economy principles. In this paper, starting from a selection of relevant indicators, capable of explaining the components of a circular and sustainable territorial system, a multidimensional and cross-scale decision support system was elaborated to identify the key components of a territorial regeneration process for the San Giovanni a Teduccio port area of the city of Naples.
