Design of Circular Supply Chain Agent-Based Model: Case of Organic Fertilizer Producer

One of the most important issues in agrifood industry and its supply chain is the existence of by-products, treated as wastes and discarded immediately to the waste disposal. This treatment might lead to loss of possibility in gaining economy value from them. Implementation of circular economy concepts could prevent the economy value loss, through utilization of said wastes as resources for other processes. While it has high opportunity in Indonesia, the implementation has met several obstacles, especially in the case of an organic fertilizer producer which operates with organic wastes as their inputs. In this research, the agentbased model of the company’s case is defined, along with the issues they met. The model is expected to be used as testing ground for various scenarios to be taken by the company in marketing and selling their products.
