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…

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…

Settore ICAR/14 - Composizione Architettonica E UrbanaThe essay questions the future's possibilities to operate on the buildings of the second half of the twentieth century according to the Italian Code of Cultural Heritage (2004-2011). When arguing how to encourage the re-use of these artifacts which are often marked by short-life technology cycles obsolescence and abandonment the ambiguities and inconsistencies of current legislative procedures deeply stress the cultural role of research experiences that use project-oriented methodologies. The comparison between some Italian and other European cases highlights the role of a design approach in the construction of a transformative protection perspective for the built matter of the second half of the twentieth century. In a framework aiming to encourage a reconciliation between the recent built environment and the new paradigms of sustainability and circular economy architecture must recognize re-cycle practices as a main theoretical and procedural node. To modernize the late Modern built environment with contemporary construction components is not simply a matter of technical knowledge and expertise: but a theme with theoretical density aesthetic and ethical values. The architectural project in this field today must ask for greater congruence between the bureaucratic and administrative levels and the real consistency of this corpus. It is a matter of identifying strategies to equip it with capabilities meanings and contents remembering that demolition wastes have unsustainable environmental costs and uncertain results concerning the necessary new attribution of political and semantic meaning that these places await.

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…
