Abstract
As the construction industry grows, it produces large volumes of construction waste, which has a tremendous environmental impact and generates public concern in the neighbouring towns. The construction industry generates a significant volume of waste and faces a challenge with poor construction waste minimisation in order to prevent adverse environmental and dumping impacts worldwide. In developing countries, regional waste management systems have increased problems. Environmental pollution (air, water, and soil) and human health issues are caused by waste produced in a country as a result of different cultural, social, and religious activities. Prior studies were reviewed to choose dimensions and items for the data gathering instrument. A pilot test was conducted to identify potential questionnaire adjustments, and hypotheses were tested using structural equation modelling (SEM). A total of 220 Malaysian construction professionals answered the survey, which yielded the results. Five hypotheses have direct correlations based on the findings, three of which have a significant effect. Furthermore, the findings reveal that policy-related factors mediate the relationship between improving factors and sustainable construction waste minimisation. In contrast, they did not mediate the relationship between current practices/generation and sustainable construction waste management. The established framework can help improve construction waste management and help achieve global sustainable development goals. The data reveal that adopting preventive plans to reduce construction waste is one of the most important aspects of enhancing profitability. This study could aid construction industry players in evaluating waste management components during the construction and design stages of a building project.
Highlights
In 2015, the construction industry significantly impacted the natural and built environment
The findings show that current practices/generation has little impact on policy-related factors but significantly impacts sustainable construction waste management
For hypothesis Hypothesis 5 (H5), this study discovered that policy-related factors affect sustainable construction waste management (β = 0.766, t = 12.133, p < 0.000)
Summary
In 2015, the construction industry significantly impacted the natural and built environment. In 2019, 16.6 million tonnes of waste were produced, constituting 38% of destruction, with 43% of those wastes ending up in landfills [1,2]. In the construction and demolition procedures, massive amounts of waste are generated. Practitioners and scholars have become deeply concerned about the difficulties interconnected with construction and demolition waste [3,4]. C&D waste is rapidly increasing and, in most nations, is not completely managed [5].
