Management of demolition phases and related waste, in a building renovation project near Salerno, Italy
2020
Compliance with recent environmental regulations, the demolition phase, within the building replacement process, plays a decisive role, in terms of execution and management methods. The contribution addresses the problems related to the management of the site, in compliance with regulatory requirements for selective demolition and disposal of waste materials. Possible organisational and procedural solutions were investigated with particular reference to the phases of selective demolition (in compliance with Minimum Environmental Criteria), excavation, handling, treatment, recycling, and disposal of waste materials.
L'ANTICO CAMPANILE DELLA CATTEDRALE DI LECCE IN UN CONSULTO DEL 1574
2016
L'antico campanile della cattedrale di Lecce si trovava in una posizione diversa rispetto a quello esistente costruito nel 1658. La maestosa torre, con cinque ordini e una terminazione a corona, era collocata di fianco all'antica facciata principale della chiesa, sul lato sinistro. Nel 1574 a causa di numerosi crolli, gli amministratori della chiesa decisero di avvalersi del parere tecnico di tre professionisti: Padoano Schiero, Padoano Baxi e Gabriele Meschinello, chiamati ad esprimersi in merito alla pericolosità di tali crolli e allo stato della torre. Vennero prodotte tre relazioni tecniche i cui contenuti illustravano la necessità di demolire la torre al fine di scongiurare eventuali d…
STATE OF PRACTICE IN THE C&DW SECTOR WHILE PURSUING CIRCULAR ECONOMY: THE ITALIAN RECYCLED MATERIALS MARKET IN ROAD ENGINEERING
2022
Construction and demolition waste (C&DW) is mainly produced during the construction, demolition, or renovation activities of engineering structures and it accounts for a remarkable amount of the total C&DW generated, as it is estimated to be around 30%. This proportion differs across countries belonging to different types of economies and tends to be greater in countries with developing economies reaching 74% of total annual production. There is a plethora of applications that C&DW can be used for under a circular economic model and in this research study a focus is being given in the utilization of C&DW within the pavement engineering sector, and more specifically, in the u…
Understanding the current state of practice in the construction and demolition waste sector through the lenses of circular economy: The Italian recyc…
Construction and demolition waste (CeDw) is mainly produced during the construction, demolition, or renovation activities of civil engineering structures and it accounts for a remarkable amount of the total C&Dw generated, as it is estimated to be around 30%. This proportion differs between countries belonging to different types of economies and tends to be greater in countries with developing economies reaching 74% of total annual production. There is a plethora of applications that C&Dw can be used for under a circular economic model and in this research a focus is being given in the exploitation of C&Dw within the pavement engineering sector, and more specifically, in the uti…
From Buildings' End of Life to Aggregate Recycling under a Circular Economic Perspective: A Comparative Life Cycle Assessment Case Study
2021
The demolition of buildings, apart from being energy intensive and disruptive, inevitably produces construction and demolition waste (C&Dw). Unfortunately, even today, the majority of this waste ends up underexploited and not considered as valuable resources to be re-circulated into a closed/open loop process under the umbrella of circular economy (CE). Considering the amount of virgin aggregates needed in civil engineering applications, C&Dw can act as sustainable catalyst towards the preservation of natural resources and the shift towards a CE. This study completes current research by presenting a life cycle inventory compilation and life cycle assessment case study of two buildin…
Sine cura. Verso il ri-ciclo dell'architettura del secondo Novecento
2019
Gli argomenti discussi nel saggio interrogano il destino che il Codice dei Beni Culturali (2004- 2011) determina per le opere del secondo Novecento. Nella costruzione del futuro di questi manufatti, che per funzione, tecnologia e cicli d’uso sono spesso segnati dall’obsolescenza e dall’abbandono, le ambiguità e le incongruenze delle attuali procedure legislative sollecitano profondamente il ruolo culturale delle esperienze di ricerca che usano metodologie meta progettuali. Il confronto fra alcuni casi italiani ed altri europei rimarca il ruolo del progetto nella costruzione di una prospettiva di tutela trasformativa per il costruito del secondo Novecento. Nel quadro di azione marcato dall’o…
Paesaggi abusivi in Sicilia
2016
La questione dell’abusivismo edilizio in Sicilia si può leggere come parte di un fenomeno più vasto, quello di una espansione poco programmata e costituita da una grande quantità di edifici costruiti prevalentemente a uso residenziale, tra gli anni ‘60 e ’80, da piccoli imprenditori o da privati, e che hanno dato vita a parti di città dimensionalmente rilevanti. Questi edifici o insediamenti urbani, che si presentano ancora frammentati e incompiuti, sono riconoscibili per materiali, per povertà di linguaggio, per tecnica costruttiva prevalente. Una gran parte di essi sono stati realizzati originariamente fuori dalle regole urbanistiche prescritte, ma nel tempo hanno prodotto tessuti e paesa…
Examining the critical factors that influence the success of construction and demolition waste reverse logistics operations
2022
The reverse logistics (RL) performance of construction and demolition waste (C&DW) differs significantly between countries. Although some countries are successfully circular, other countries are still far behind; with C&DW being largely directed to landfills or being illegally dumped. There is a lack of guidelines on the requirements for transitioning countries towards C&DW diversion, and little attention has been given to the factors that influence the success of C&DW RL and increased circularity. This study aims to develop a framework that helps in structuring and assessing the success of C&DW RL on a regional level and serves as a guide for transitioning developing co…
