A simulation model using system dynamic method for construction and demolition waste management in Hong Kong

Abstract

Purpose As construction and demolition(C&D) waste is one of the main solid waste generators in Hong Kong, its impact on the environment has become an imperative issue to the involved stakeholders. Although, C&D waste management has been receiving increasing attention from stakeholders and researchers since the early 1980s, how to manage C&D waste efficiently and effectively is, however, still in its early stages. Past research on C&D waste management has mainly focused on the separate aspects of waste management including waste reduction, reuse, recycle and response. A new approach is made in this paper to improve C&D waste management. Design/methodology/approach A simulation model is developed based on system dynamics methodology for strategic planning of C&D waste in Hong Kong by incorporating the relationship of major activities inherently involved in C&D waste management. Findings Finds that such an integrated simulation model will have the potential to assist decision makers and practitioners to better understand the complexity of information and processes involved in managing C&D waste throughout a project's life‐cycle. Originality/value This has shown that management of C&D waste can be facilitated by means of system dynamics to provide a better understanding of the dynamic interactions and interdependencies of the key areas of the C&D waste management process.
