Estimation of construction and demolition waste volume generation in new residential buildings in Spain

Abstract

The management planning of construction and demolition (C&D) waste uses a single indicator which does not provide enough detailed information. Therefore the determination and implementation of other innovative and precise indicators should be determined. The aim of this research work is to improve existing C&D waste quantification tools in the construction of new residential buildings in Spain. For this purpose, several housing projects were studied to determine an estimation of C&D waste generated during their construction process. This paper determines the values of three indicators to estimate the generation of C&D waste in new residential buildings in Spain, itemizing types of waste and construction stages. The inclusion of two more accurate indicators, in addition to the global one commonly in use, provides a significant improvement in C&D waste quantification tools and management planning.

New quantification proposal for construction waste generation in new residential constructions

“…Furthermore, the previous literature highlights that masonry is the main activity generating CDW (Katz and Baum, 2011;Villoria Saez et al, 2012). Considering this issue, the amount of waste generated during masonry works in two different projects ewith the same total floor areadbut one designed with big surface dwellings and the other with small studios, will differ eas the latter has more brick interior partitionse.…”

Construction and Demolition Waste in Romania: The Route from Illegal Dumping to Building Materials

“…Unreliable estimates lead to inadequate policies and unsound waste management practices in emerging economies like India [32]. European countries deal with same challenges and new approaches are required to provide better estimations of C&DW flows in different construction stages [33] or to examine the spatial trend of building material stock and potential demolition wastes including the analysis of historical maps [34].…”

Alternative construction and demolition (C&D) waste characterization method proposal

“…Previous studies about generation estimates and characterization focus solely on collecting the generating source's data, e.g. in residential and non-residential construction sites (KATZ; BAUM, 2011;SÁEZ & MERINO, 2011;LLATAS, 2011).…”
