Abstract

The mushrooming of the construction industry in China has generated considerable quantities of construction and demolition (C&D) waste, along with related sustainability and environmental issues. This study aims to examine the development of Construction Waste Management (CWM) practices in China. Specifically, the objectives of this study are to identify the implementation aspects of CWM practices, to compare the concept of CWM practices compared to traditional CWM practices when used an Industrialized Building System (IBS) building methodology and to evaluate the awareness, knowledge, and practices of stakeholders in relation to implementation of CWM practice.The main goal was to evaluate and compare the cost-benefit aspects of the respective CWM practice. A quantitative research approach was adopted, by means of gathering survey responses using a structured survey instrument distributed to 253 construction professionals within Beijing, including contracted site managers, engineers and environmental officers. The data were analyzed using descriptive statistics, chi-square tests, correlation analysis, and Generalized Linear Models (GLM) for analyzing the implementation practices, stakeholder awareness, and regulation compliance. SPSS was used to run descriptive analysis, correlations and regression models to interpret the data collected. The results indicate that IBS projects yield greater waste reduction possibilities due to prefabrication efficiencies, while conventional methods are the predominant practice for convenience, durabilities, and lower upfront costs. This study also indicates that using IBS could be a viable and sustainable solution for managing construction waste in fast-developing cities such as Beijing. Overall, the results have implications for research and have implications for industry by encouraging the use of IBS to improve the current waste management practices and environmental impact of the building industry. Furthermore, the study highlights the need for more training, and supportive policies, for implementation of sustainable construction waste management practices in the Chinese construction practice.
