摘要

The paper tackles a topic related to the use of prime material and recycled materials in construction, in the framework of the circular economy, where recycled aggregates can be considered, in part or even totally, as second prime materials for the construction sector. In particular, the authors describe the main phases of the MEISAR project, developing a circular cluster territorial model so that the quantity of recyclable materials can be estimated and geolocalized in the most appropriate processing plant, as well as assessing the potential market. In the study we combine spatial planning problems and industrial location factors of natural and recycled aggregates and concrete production plants through the geospatial representation of the MEISAR map. The closed market of Sardinia is analyzed and, in particular, the case study of the new soccer stadium in Cagliari, which involves the demolition of the existing stadium that will represent a source of “secondary” raw materials for the construction of the new stadium designed by the consortium Sportium.
