Management of Waste Generated by Construction and Demolish in Construction Industry Projects Using the Dynamics of Systems Approach

Economic tools are definitely an effective way to encourage or enforce contractors to enforce environmentally-friendly practices. Previous studies on this subject mainly focus on the management of waste of construction and demolish (C & D) from the static point of view, which does not take into account the nature of its dynamic by taking all necessary activities in the waste chain. Therefore, the purpose of this paper is to explain the dynamics and relationships between the components of C&D waste management and to analyze the costs and benefits and cost of transportation and fuel consumption using the system dynamics approach. The findings show that the implementation of C&D waste management has many benefits, but the higher cost of landfill at authorized sites will result in more net profits, which will be accompanied by disadvantages such as environmental damage. In addition, the public is suffering from landfill in unauthorized locations and imposing environmental costs due to illegal evacuation. Simulation results also show that increased landfill in unauthorized locations increases fuel and energy consumption and therefore increases fuel consumption costs. This study by investigating and evaluating the researches and measures taken on the waste and waste spillway aims to clarify the use of a systematic approach using the dynamics of systems in a direction in which it is possible to use contract cost-benefit analysis to encourage contractors to disposal of Construction waste in a way that is conducive to the development of the building industry and the preservation of the environment and the resulting savings.
