Feasibility study of reverse logistic of steel waste in the construction industry
Construction and demolition (C&D) waste are increasing due to population and economic growth. Most of C&D waste
materials, including steel waste, can be managed with the reverse logistics (RL), including directly reuse, recycling, and
remanufacturing. However, most waste is dumped into landfills which cause environmental problems. This study examines the
implementation of reverse logistics of steel waste in the construction industry utilizing a system dynamics approach. The
dynamic model consists of six sub-models. The simulation results reveal that in the initial years, the net profit value of the RL
implementation program is negative due to high investments in labors, trucks, and machines. It takes five years for the net profit
to be positive, and eight years to achieve the internal rate of return of 12%. The construction company can use the developed
dynamic model as a guideline to better understand RL implementation and plan for better implementation programs
