Feasibility Study of Recycled Paver Block for Circular Economics Using System Dynamics Model

The construction industry generates a lot of construction and demolition waste (CDW), which hinders the sustainable development goals (SDGs) targets. However, CDW materials have gained popularity in the construction sector to address the aggregate shortage. In this regard, the manufacturing of recycled paver blocks (RPB) and its usage in the construction industry has been trending all over the globe. However, the cost of RPB is still a crucial issue, as it varies with the time and demand of manufacturing recycled materials. Therefore, the study aims to estimate and forecast the cost of five different grades of RPB using the system dynamics (SD) approach. For this, the present study first shortlisted 25 cost components for manufacturing RPB using a literature review and expert judgments. Then, the cause-and-effect and stock-and-flow diagrams are created to explore the interdependency among these 25 components. After that, if-then-else function was used to compute the dynamic interaction mechanism between cost components. Finally, the model is validated by conducting the structure and behavior verification test. Thus, this study can help the use of RPB in construction projects and bring clients and contractors toward the circular economy (CE).
