Re_Power station. Reuse of Augusta Power Station
2016
Raramente accade che il recupero di un edificio possa riassumere su di sé tutta l’emblematicità, anche simbolica, di un reale cambio di paradigma rispetto a scelte contraddittorie fino ad oggi compiute su un territorio; ma ciò può accadere, con piena evidenza, nel caso della Centrale termoelettrica ENEL “Tifeo” di Augusta (SR). Il suo recupero si presenta infatti come uno dei casi studio tra i più interessanti nel panorama internazionale, per le dinamiche che questo condensa, per le nuove visioni strategiche e per i mutamenti di senso che attorno ad esso si possono prefigurare. Il libro raccoglie i risultati della ricerca condotta nell’ambito del Dottorato di ricerca in Architettura/Progett…
Reuse and recycling in construction: novel photocatalytic nano-mortars from valorised industrial wastes
2021
Production of novel eco-composite nano-mortars for architectural finishing, designed to combat environmental pollution affecting building shells, is reported. Specimens consist of a natural hydraulic lime mortar matrix doped with various kinds of nanophotocatalysts, produced from valorized industrial wastes: TiO2-hexaferrite from Fe3O2, and Ti(SO4)2-hydroxyapatite from Atlantic codfish bones. Samples were characterized and their photocatalytic activity was evaluated. Analysis showed that industrial wastes may be usefully reused to produce a new generation of sustainable, cheap and multifunctional novel building materials.
Development of New Bio-based Materials Derived from Sicilian Agri-Food Industry Waste
2023
La necessità di soluzioni di materiali da costruzione a base biologica e sostenibili è aumentata drammaticamente nell’ultimo ventennio. Questa ricerca esplora i possibili modi per riutilizzare materiale di scarto a base biologica (come i gusci della frutta secca), derivati dall'industria agroalimentare, per la produzione di nuovi materiali da costruzione sani in linea con i principi dell'economia circolare. L’analisi di alcuni casi di studio precedenti e le attuali ricerche dimostrato la possibilità di riutilizzare i gusci della frutta secca per la realizzazione di nuovi componenti edilizi. Le attuali tendenze mostrano che le resine sintetiche sono sempre più usati come legante per incollar…
Dopo l'obsolescenza. Progetti per i viadotti ferroviari dismessi
2013
This article focuses on the increasing number of abandoned railways converted into new parkways, briefly investigating them trough the prism of obsolescence. Over the past forty years, the features matching with the average lifetime of infrastructural buildings have became of growing relevance dealing with contemporary policies in restructuring our territories. In the beginning of 21th century, facing the new challenges of the post-carbon era, cities of developed society are riddled with technical ruins, testaments to their recent productive past. Since the entanglement of transport infrastructure, industry and architecture highly represents important segments of 20th century urban tissues,…
Cultural Commons. Governance partecipativa del patrimonio culturale
2016
Una governance patrimoniale efficace necessita di un profondo coinvolgimento sociale per una partecipazione condivisa alle azioni di salvaguardia e valorizzazione. La responsabilità si trasferisce alle collettività territoriali, il che comporta anche un ripensamento della dimensione operativa degli strumenti di governo del territorio verso il potenziamento della dimensione locale e della partecipazione democratica alle scelte di pianificazione, la promozione dell’apprezzamento, l’appropriazione dei valori del patrimonio culturale e la partecipazione collettiva alla loro gestione.
Repeated Load Triaxial Testing of Recycled Excavation Materials Blended with Recycled Phyllite Materials
2022
Recycled Excavation Materials (REM) are becoming viable alternative construction resources due to their economic benefits. However, REM may be composed of weak rocks, e.g., phyllites, limiting the use in a base layer. The present paper attempts to further the knowledge of the mechanical performance of REM by performing Repeated Load Triaxial Tests (RLTT). REM are mixed with Recycled Phyllite Materials (RPM) in systematic blends of 0%, 25%, 50%, and 100%. The batches’ resilient modulus (MR) and permanent deformation (PD) characteristics were assessed to establish the maximum RPM allowed into REM while maintaining the required performance. Hicks and Monismith’s and Uzan’s mo…
Re-think, Re-load, Re-cycle: Mediterranean Urban Metamorphosis
2013
Metamorphosis is the new and powerful keyword in time of crisis. We are not undergoing a mere -even though dramaticpassing situation, but we are living in a crisis which requires a metamorphosis of the ecological, cultural, economic, social and political systems to get out of it other than we were when entering it. The metamorphosis will have to be mainly urban, because we are now in the Urban Age in which more than half the population live and work in cities, at levels exceeding 80% in Europe. The city, as the predominant form of inhabiting, is invested with the “responsibility” of producing innovative, more sustainable, intelligent and creative life styles, able of generating the innovati…
Re-cyclical Urbanism. Visions, Paradigms and Projects for the Circular Metamorphosis
2017
The European Commission has clearly stated that more intelligent, sustainable and competitive development requires a paradigm shift in which the territory is construed as a primary resource, considered the holder of “development cells”, which are too often underused or mystified with regard to their real potential for use (EC, Directorate-General for Research and Innovation, 2012). Cities designed and built on land rent — on which Italy set a benchmark — need to be replaced with cities of social and cultural profitability, value creation and jobs production. Cities that recycle already-used land to avoid energy waste, smarter cities — not just technologically, but also wiser and more sentie…
Time–carbonyl groups equivalence in photo-oxidative aging of virgin/recycled polymer blends
2004
AbstractThe photo-oxidation behaviour of polymers is strongly dependent on the initial amount of carbonyl groups along the chains. The growing use of recycled post-consumer polymers coming from products used outdoors and then photo-oxidised, both pure and blended with the same virgin polymer, gives rise to an unpredictable behaviour of weathering resistance of products made with these materials. The present work shows that the carbonyl group–exposure time curves can be shifted along the time axis to give a single generalised master plot. It is then possible to predict the formation of the new carbonyl groups by knowing only the initial amount of the same carbonyl groups. The same shift fact…
Extended valence theory perspective on consumers' e-waste recycling intentions in Japan
2021
The gravity of the electronic waste (e-waste) crisis can be attributed to consumers' low participation in ensuring the proper disposal of such materials. Motivating consumers to recycle e-waste requires a deeper understanding of the dimensions that underlie behavioral intentions. Accordingly, the present study uses the novel framework of Valence Theory (VT) to examine how consumers evaluate their decision to recycle e-waste. The authors propose an extended VT model incorporating consumer values (value compatibility, openness to change, and environmental concerns), which is validated using cross-sectional survey data from 774 Japanese consumers. We also examine the role of different moderato…
