Resumen
Although reuse in the broadest sense also includes the reuse of components of historicbuildings, the relevant reuse from the point of view of the size of the wasteproblem is the re-introduction of waste materials into a new production process,possibly within the same cycle that generated them. A fundamental role is playedby the initial design phase of the building, which must be conceived in function of afuture final disassembly of the building and not of its demolition. The selective disassemblyof buildings is aimed at making available monomaterial fractions suitable fortreatment in special recycling plants that allow waste to be used as secondary rawmaterials. The data that emerged showed that selective demolition is economicallyviable compared to traditional demolition in the hypothesis that the two opposingscenarios are selective demolition with a very high percentage of recovered materials,therefore valorised as secondary raw materials, and the traditional demolitionwith transfer of rubble to special waste landfills.The environmental advantage of selective demolition is undoubted because itachieves many positive results at the same time: a drastic reduction in the amount ofwaste to be deposited in the area, protection from the risks of soil pollution associatedwith reuse for filling and a saving in natural raw materials equal to the percentageof recycled material returned to the production cycle. Many researches carried outrecently and still in progress at international level agree in confirming that a particulardisassembly of the building and appropriate treatments allow a high level of qualityin the recovery of materials that can thus compete with the natural aggregatestraditionally used.
