Abstract: In a system of production and consumption sustainable supply chain management plays a crucial role in overseeing and curbing excessive waste. This research introduces two interconnected supply chain dedicated to waste elimination within the production and consumption processes. The study integrates the tenets of the circular economy (CE) explicitly emphasizing the 3R concepts, which are Reduce, Restore, and Recycle. Within this framework, the initial product in the primary chain follows degradation and transforms raw material for the production system of the secondary chain (secondary production facilities). While transporting used products to recycling facilities losses can happen due to leakage from the containers during transportation. This study unique contribution is exemplified by determining the optimal values for price discounts and container leakage costs emphasizing a key aspect of the CE: the reduction and recovery of discarded items in successive stages. Mixed-integer nonlinear programming is employed for the dual supply chain to optimize the joint cost function using classical methods. A noteworthy numerical outcome is established to validate this concept: with an increase in the leakage cost per container from $5 to $10 overall supply chain costs were immediately reduced by approximately 90%.
