Abstract: The current logistics model for finished pesticide products and packaging waste is characterized by low efficiency, high cost, and extended cycle times, resulting in significant environmental pollution and threats to personal safety. Therefore, from the perspective of cooperative game theory, this study proposes the formation of a collaborative alliance among multiple agricultural enterprises to integrate the pickup and delivery of finished pesticide products and packaging waste. An integrated logistics model and operational mechanism are designed to manage these processes. A vehicle routing problem model with time windows is constructed to facilitate simultaneous pickup and delivery. Shapley value and kernel solution methods are employed for cost allocation among collaborative enterprises. The model's impact is analyzed in terms of delivery cost, hazard risk probability, and recycling rate. The results indicate that, compared to traditional logistics models, the proposed collaborative pickup and delivery integration model reduces the total delivery cost by 22.62% to 43.40%. Agribusiness enterprises experience relative cost savings exceeding 38.62%. Furthermore, the recycling cycle of pesticide packaging waste is significantly shortened, with a 31.58% decrease in hazard risk probability on average, and a corresponding increase in recycling rate of more than 34.95%. If implemented nationwide, the model is estimated to enable the annual recycling of approximately 43,900 tons of pesticide packaging waste, offering substantial benefits for environmental protection and public safety.
