Online Appendices for "Circulise4LCE: A Model-Driven Sustainability Development Framework for Local Circular Economy Engineering and Simulation"

Appendices A–D provide the supplementary materials for the Circulise4LCE framework. They include (A) a conceptual overview of the simulation logic and its underlying assumptions, (B) detailed parameter values and community dynamics modeled in the Fanyatu case, (C) the full source code of the SustainableCommunitySimulationGUI.java that drives the simulation environment, and (D) representative simulation output visualizations. These materials support the reproducibility, pedagogical integration, and practical application of the model-driven local circular economy framework proposed in the paper.
