Analysis of the Underlying Causes of Waste Generation in Indonesia’s Construction Industry

Abstract

The construction industry produces enormous volumes of construction waste that have a negative influence on the environment. This study examines the underlying causes of waste generation in the Indonesian construction industry based on professional perspectives. This study used a questionnaire as a research instrument and examined the data with reliability and exploratory factor analysis. Based on the analysis, there are eight underlying causes that contribute to the generation of construction waste in the Indonesian construction sector. The five most significant underlying causes of waste generation that obstruct sustainable practices include waste-inducing site and human resource management approaches, inadequate collaboration and support among stakeholders, equipment management, material logistics management, and poor working environments. As a result, it is crucial for Indonesian experts to pay attention to the factors that contribute to waste generation in order to lessen its negative effects on the environment and promote sustainable practices.

Spatial and Temporal Evolution Patterns of Construction Waste Generation and Influencing Factors - China Case Study

“…On the one hand, higher labor efficiency indicates that construction workers in the area are more experienced and competent, and they will pay greater attention to the use and loss of materials in the construction process in order to prevent unnecessary wastage (Karunasena et al, 2023). Labor efficiency, on the other hand, is also responsive to the level of management of the building construction process, and a scientifically sound and reasonable management process can significantly reduce construction waste generation (Fitriani et al, 2022).…”

Investigation of Construction and Demolition Waste Causes Toward Comprehensive Taxonomy

“…It has been confirmed that WCFs related to design and pre-contract stage (F4) have devastating effects on the WG where an inappropriate design results in up to 33% of the CW (Chellappa et al, 2023) and adoption of sustainable design mainly prefabrication could enable 52-84.7% cut of the CW (Fitriani et al, 2023) and almost 100% recovery of the demolition waste (Begum et al, 2009). Eze et al (2022) reported that 96.88% of F3-related WCFs are equally sources of cost overrun.…”

“…Likewise, procurement and onsite construction stages are highly contributing to the CW and are influenced by transversal WCFs families. Fitriani et al (2023) showed that 25.96%, 19.96%, 14.25%, and 11.59% of CWs could be explained by improper management of equipment, onsite material logistics, and working milieu (F6); onsite-related inadequate collaboration and communication on the construction site (F3); improper site planning and workforce management (F6), and F1 due to involved stakeholders in the construction operation (waste behavior, incompetency, and lack of training and experience), respectively. Based on risk severity and occurrence analyses, Bachayo et al (2022) revealed that among 8 WCFs related to procurement and supply chain, 7 fell in the red zone with orders variation as the most occurrent, incompliant materials with specifications as the severest, and mistakes in quantity surveys as the most impactful on the cost.…”

“…Reduce, Reuse, Recycle then Disposal (3RDs') principle is considered as important guidance for C&DWM (Yuan et al, 2018). Waste reduction strategies consist of upstream prevention of waste generation especially during design and construction processes where elimination or reduction of WG is significant and more economical (Fitriani et al, 2023). Meanwhile, waste recovery (Recycling or Reuse) refers to downstream strategies aiding in reinserting wasted MCs into the supply chain of industries' markets rather than sending them to disposal at landfills.…”

“…Bajjou and Chafi (2022) listed 28 WCFs structured into 6 clusters related to design and documentation, people, contractors, management/ finance/ administration, execution/ performance, and external factors. Fitriani et al (2023) listed 47 WCFs that were divided according to 8 themes: site and human resource management approaches, inadequate collaboration and support among stakeholders, material logistics management, equipment management approach, poor working environment, incompetency and waste behavior, poor communication on the construction site, and lack of training and experience.…”
