The paper illustrates some of the ongoing results of the interdepartmental research Prosit “PROgettare in SostenibilITà: qualification and digitalization in construction”, analyzing some of the key steps aimed at testing, within the actual regulatory and technological framework, new possible applications of recycled materials from construction and demolition (C&D) in sustainable and innovative supply chains. In Italy, in particular, about 98% of the non-hazardous waste from C&D activities already in 2018, as documented by the Eurostat’s “Recovery rate of construction and demolition waste” report. Nevertheless, C&D waste is mainly reused 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 the reuse of these resources to realize 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.
