| Abstract | Developing countries including Thailand are experiencing issues related to increase waste generation and improper waste management. The country’s domestic waste utilization is only 20 - 26%. Efficient waste management and increased waste utilization is possible only by overcoming problems and constraints in Reverse Logistics (RL) system. To address these issues, this study aimed to investigating the current practices in RL. The study focused on the current RL practices in recycling in Bangkok and its vicinity. A mixed method research approach was used, integrating qualitative and quantitativ e methods, exploring the characteristics and stakeholders in RL. Factors influencing RL practices were determined and differences due to variation in capacity and type of business were examined. Data were gathered through a literature review and in - depth i nterviews of key stakeholders involved in RL, and, a questionnaire survey of 98 managers of separating centers (SPs) probing their practices. The result shows that the performance of cooperative like franchise is better and they are more competitive in RL practice than non - franchise. Based on size classification, medium and large SPs are more competitive than small SPs in waste management perfor mance. The factors significantly affecting RL practice were social relationships, the use of modern technology, experience level of labor, and environmental conditions . Small SPs were less efficient in RL practices. SPs that operated as cooperative - like fr anchise businesses were more efficient in RL practices than the non - franchise types. Additionally, these SPs had more bargaining power with waste buyers and sellers. The constraints in RL practice were related to access to financial facilities, markets, la bor, management/technology, and legal issues. The study suggests there are reduced costs and increased benefits of RL in waste systems by separating waste at its source, cooperation, training labor, and use of modern technology . Cooperative practice can he lp to reduce the operating cost and ultimately increase the benefit to the stakeholders. Access to modern technology, availability of funds from financial institutes, reducing taxes and providing good incentives to SPs can enhance their efficiency. Cost - be nefit analysis of SPs and an optimization approach to minimize cost or maximize benefit are recommended for future studies. |
