With growing environmental awareness and increasing demand for valuable resources, waste recycling has become a major concern. This study examines the profit of recyclers and platforms by taking into account the level of trust in the reverse logistics system, considering the following scenarios: an online recycling platform builds trust or not, in centralized and decentralized models. The results show that building trust can effectively generate more revenue for the online recycling platform system with increased demand if the cost of building trust is relatively low. The revenue-sharing contract is more profitable than the cost-sharing contract, but fails to achieve optimization in the integrated setting. We propose a new decision-making tool for optimal strategies under different decision-making models.
