This paper develops a decision-making methodology for urban regeneration projects based on the use of data-driven procedures and technologies for the conversion of former industrial areas to residential use. The proposed approach is aimed at the elaboration of an information management protocol for the generation of design scenarios, starting from the assessment of the regulatory and technical compatibility of the possible transformations with the existing constraints. This paper describes the application of the methodology to several buildings in the ex-Corradini complex in Naples to be used for different types of residential functions, in a framework of high uncertainty and complexity, also due to the inaccessibility and abandonment of the site.

The paper illustrates some of the results of the interdepartmental research Prosit “PROgettare in SostenibilITà: qualification and digitization in construction”, analyzing some of the key steps aimed at testing, compatibly with the regulatory and technological framework, new possible applications of recycled materials from construction and demolition (C&D) in sustainable and innovative supply chains. The Eurostat report “Recovery rate of construction and demolition waste” of 2022 shows how Italy, already in 2018, starts to recover about 98% of the waste from C&D activities considered non-hazardous, mainly for the construction of embankments and road foundations. The research, therefore, identifies in the use of file-to-factory technologies a possible way to extend the scope of application of the reuse of these resources to the realization of diversified and non-standard manufactures and components, in the perspective of a greater spread of virtuous practices of circular economy in the construction sector. In this sense, a process “algorithm” is described, designed to be scaled and replicated in different contexts for similar purposes.
