Analysis of Waste Generation Characteristics during New Apartment Construction—Considering the Construction Phase

Abstract

The waste generation rate (WGR) is used to predict the generation of construction and demolition waste (C&DW) and has become a prevalent tool for efficient waste management systems. Many studies have focused on deriving the WGR, but most focused on demolition waste rather than construction waste (CW). Moreover, previous studies have used theoretical databases and thus were limited in showing changes in the generated CW during the construction period of actual sites. In this study, CW data were collected for recently completed apartment building sites through direct measurement, and the WGR was calculated by CW type for the construction period. The CW generation characteristics by type were analyzed, and the results were compared with those of previous studies. In this study, CW was classified into six types: Waste concrete, waste asphalt concrete, waste wood, waste synthetic resin, waste board, and mixed waste. The amount of CW generated was lowest at the beginning of the construction period. It slowly increased over time and then decreased again at the end. In particular, waste concrete and mixed waste were generated throughout the construction period, while other CWs were generated in the middle of the construction period or towards the end. The research method and results of this study are significant in that the construction period was considered, which has been neglected in previous studies on the WGR. These findings are expected to contribute to the development of efficient CW management systems.

A comprehensive model for quantifying construction waste in high-rise buildings in India

“…A few studies have quantified construction waste by measuring the truck volume (Cheen et al, 2018) or truck weight (Kim et al, 2019) or by using the waste hauling tickets (Bakchan and Faust, 2019). However, such methods are challenging in developing countries as the common practice is to dump construction waste illegally on roadsides, river basins or on vacant lands.…”

Analyzing the Freight Characteristics and Carbon Emission of Construction Waste Hauling Trucks: Big Data Analytics of Hong Kong

“…Owing to its non-combustible nature, construction waste normally ends up in disposal facilities, such as public fills or landfills [ 7 , 8 ]. A large number of construction waste hauling trucks (CWHTs) have been mobilized to transport such construction waste to various disposal facilities [ 9 ].…”

A Sustainable Approach for the Refurbishment Process of Vernacular Heritage: The Sesga House Case Study (Valencia, Spain)

“…In terms of the reduction in the CO 2 emissions of architecture during its life cycle, it is increasingly claimed that the refurbishment, conservation, retrofitting and adaptation of existing architecture are more sustainable processes in terms of the environment and their possible effect on climate change than their demolition in order to build new constructions [29][30][31]. Thus, there are growing numbers of guides and measures to prevent the production of CO 2 as much as possible in building construction [31][32][33][34]. However, in terms of LCA application to the retrofitting processes, once again these are mostly dwellings dating from the mid-20th century, according to the bibliographical review [35][36][37], and there are extremely few cases of this assessment being applied to heritage buildings [38,39].…”
