Organic waste management requires an approach that supports resource recovery while considering economic potential and greenhouse gas (GHG) emissions. This study aimed to develop a conceptual system dynamics model for organic waste processing at Gedebage Wholesale Market, using windrow composting as the baseline and anaerobic digestion in a biodigester as an alternative scenario. A qualitative system dynamics approach was applied through literature review, preliminary study, system boundary definition, conceptual model development, variable identification, and Causal Loop Diagram (CLD) construction. The results show that each CLD forms one balancing loop representing the interaction between organic waste accumulation and the rate at which material completes processing. The two pathways differ in treatment process, recovered product, and causal relationships associated with economic potential and GHG emissions. Future studies should extend the model to a Stock and Flow Diagram and quantitative simulation to enable dynamic comparison of the two pathways.
