Paper Short Abstract:

This research sheds light on the dynamics of material management in the demolition industry of Lombardy, Italy, emphasizing context-related issues and preferences in decision-making regarding sustainable practices.

Paper Abstract:

Materials used in the construction industry pose environmental challenges, making a significant contribution to the planet's waste. They represent both a value and a cost for demolition companies, influencing their budgetary decisions for a project based on such assessments. Knowledge, especially expert knowledge, is utilized to assess and decide how to manage specific materials, distinguishing between what qualifies as valuable waste, non-valuable waste, and what can be reused in its original state, thereby not classified as waste. However, the determination of value is frequently highly contextual and is often influenced by the historical prevalence of recycling practices, constituting a substantial industry.

In this paper, I investigate practices of reuse and recycling within the construction industry in Lombardy, Northern Italy. Employing participant observation at demolition sites, I investigate contemporary demolition practices in Italy. Specifically, my focus lies on the trajectory of materials and an examination of the industry's modus operandi concerning the disposal of materials. While recycling seems to be the most common and established practice in the field, reuse remains on the periphery, used occasionally, especially when mandated by legislation for historic conservation. While it is sometimes actively pursued, various challenges are associated with it. Uncertainties arise from everyday practices of reuse when issues such as cost, time, logistics, and adherence to energy or security standards are faced. Although reuse may appear to be the most sustainable option, it is not always the case. Consequentially, decisions regarding reuse are context-dependent and frequently subject to changes.
