Dynamic model for construction and demolition waste recycling in Bangkok, Thailand

摘要

With higher numbers of buildings and infrastructures in Bangkok, the number of construction and demolition (C&D) waste increases continuously. These wastes, if not properly managed, will create environmental problems in long term. This study utilizes a system dynamics modeling technique to develop a C&D waste management model. Data and related relationships were collected to develop simulated equations for a dynamic model. The simulation results show that more wastes are sorted an d recycled over time when more labors and machines are hired and purchased. Different environmental budgets available to perform the recycling program are also examined, so that the construction industry can effectively plan for its C&D waste management program implementation.
