Construction waste management and its influence on enhancing environmental performance a case study of Kulim Hi-Tech Park Malaysia

Abstract The rapid expansion of industrial development projects has raised growing concerns regarding the environmental impacts associated with construction waste generation. Although construction waste management has been widely discussed in sustainability research, empirical studies focusing on waste generation and management practices within large-scale industrial technology parks remain limited, particularly in developing economies. This study examines construction waste generation patterns and management practices across construction projects located in Kulim Hi-Tech Park (KHTP), Malaysia, with the aim of examining how these practices relate to environmental performance in industrial construction contexts. A multiple case study approach was adopted, involving three construction projects within KHTP. Data were collected through site observations, project documentation, and interviews with key project personnel to identify waste types, quantities, and on-site waste management practices implemented during construction activities. The analysis incorporates comparative indicators, including waste intensity and temporal waste distribution, to examine variations in waste generation across different stages of construction. The findings suggest that construction waste generation varies across project phases, with higher volumes generally observed during periods of intensive structural and installation activities. The results also indicate that waste management practices such as material segregation, improved handling procedures, and recycling initiatives are associated with reduced landfill disposal and more efficient use of construction materials. These outcomes suggest potential improvements in environmental performance within the context of the case study projects. Overall, the study provides empirical insights that may support construction practitioners and policymakers in strengthening construction waste management strategies and promoting more sustainable practices in large-scale industrial development projects, including approaches aligned with circular economy principles.
