Abstract

Objective: Circular economy is an international approach that relies on ecology and closed-loop economic systems. In this model, companies are required to optimize the use of resources in their processes and along the production and supply chain. The aim of this paper is to identify opportunities for improving the circular economy within the pistachio agricultural supply chain in Kerman Province.
 
Method: This research was conducted using a fieldwork approach from the year 2022 to 2024. First, stakeholders were identified in order to determine the relevant network relationships. The process of circular economy production was specified based on expert opinions across different sections of the pistachio value chain. Key variables were determined and evaluated based on scientific documentation. Subsequently, the weight of each dimension was calculated using the Analytic Hierarchy Process (AHP). CEL (Circular Economy Level) variables were computed to assess the level of circular economy within the supply chain. Statistical tests such as the Kruskal-Wallis test and clustering methods were also employed throughout the research process.
 
Results: The results showed that the material sourcing, design section, distribution and sales section, and the remanufacturing section have the most deficiencies in the supply chain. Using clustering methods, three clusters were identified, with the third cluster recognized as having superior performance across different dimensions. Finally, it was determined that employees' performance in terms of CEL (Circular Economy Level) is not dependent on the specific link of the chain in which the employee is located, indicating that the strategy designed for the entire supply chain is coherent and logical.
 
Conclusion: To improve efficiency and productivity in the pistachio value chain, it is recommended that optimal use be made of the by-products generated in the pistachio production system. The proposed strategy includes value-adding processes such as the production of organic fertilizers, biofuels, growing substrates, animal feed, and hygienic and cosmetic products. Implementing these approaches within the framework of a circular economy (CE) can significantly contribute to waste reduction and increased added value, ultimately leading to sustainable and economic development in the Kerman region.
