A Synthesis of Express Analytic Hierarchy Process (EAHP) and Partial Least Squares-Structural Equations Modeling (PLS-SEM) for Sustainable Construction and Demolition Waste Management Assessment: The Case of Malaysia

Abstract

Construction and demolition waste (CDW), as the main consequence of construction and demolition (C&D) activities, has severely affected our sustainability needs. However, construction and demolition waste management (CDWM) lacks the integration of sustainability concepts. Thus, there is a great need to include sustainability dimensions in CDWM to reach sustainable construction and demolition waste management (SCDWM). This study aims at empirically investigating SCDWM by analyzing the impacts of factors that contribute to sustainability aspects of CDWM on waste management hierarchy (WMH), including reduce, reuse, recycle, and disposal strategies. According to the literature, 26 factors were initially identified and grouped under four categories, namely environmental, economic, social, and administrative, that contribute to sustainability aspects of CDWM. Subsequently, a pilot test was performed to assess the significance and applicability of these factors in the Malaysian construction industry by implementing the express analytic hierarchy process (EAHP). Then, a questionnaire survey was performed to collect data from 132 construction companies involved in CDWM. Partial least squares-structural equation modeling (PLS-SEM) was used to test the hypothetical relationships by applying SmartPLS software. Results demonstrated that the economic aspect of CDWM (main category) and “public environment contamination due to illegal waste dumping” (sub-category) were the most influential factor in SCDWM in Malaysia.

Identifying the Barriers to Sustainable Management of Construction and Demolition Waste in Developed and Developing Countries

“…Sustainable management of C&DW is therefore of paramount importance to mitigate and reduce the environmental impacts of C&DW. Thus, it takes into consideration reducing raw material consumption, reusing materials, appropriate recycling mechanisms, and minimizing waste generation from construction and demolition tasks [18]. Despite great previous efforts, the current practice in the construction industry is far from reaching the goals of sustainability to fully achieve sustainable construction.…”

“…Prior studies have assessed the barriers to sustainable construction and demolition waste management (C&DWM). Some studies showed that the economic concerns are the most influential in C&DWM from both governmental and institutional perspectives [18,19]. Negash et al [1] found that the eliminating regulatory and social barriers can significantly enhance the performance of C&DWM.…”

The Need for a Proper Waste Management Plan for the Construction Industry: A Case Study in Lebanon

“…During the construction, renovation, and demolition phases of a project, there is an enormous consumption of raw materials, which creates a substantial amount of waste [8,9]. The quantity of construction and demolition (C&D) waste, also known as solid waste, generated from C&D activities is increasing [10], and it is increasingly threatening to the public environment and human health globally [11].…”

Developing a Novel Integrated Generalised Data Envelopment Analysis (DEA) to Evaluate Hospitals Providing Stroke Care Services

“…Operation Research is a field of study that uses advanced analytical methods to understand complex systems and make the right decisions [ 9 , 10 , 11 ]. Simulation techniques [ 12 , 13 , 14 , 15 ], mathematical optimisation [ 16 , 17 ], and decision analysis [ 18 ] are just a few of the ways OR helps enterprises and organisations improve their operations. OR, with its emphasis on increasing efficiency [ 19 , 20 ], cost-effectiveness [ 21 , 22 ], and decision-making [ 23 , 24 ], is particularly valuable for analysing complicated health issues, particularly in contexts where disease burden is high, but health systems are not well prepared.…”
