Abstract: The waste generated from tire manufacturing process can create long term environmental and health hazards. The present study used a multi-criteria decision analysis (MCDA)-based approach to evaluate the feasibility of popular rubber waste management alternatives currently available. Based on expert opinions and a literature survey, 16 criteria, and six alternative rubber waste management strategies were identified. The technique for order of preference by similarity to ideal solution (TOPSIS) method integrated with SWING was applied to identify feasible solid waste management alternatives for waste that generate at the end of the production process from the tire manufacturing industry. Based on the results, pyrolysis was identified as the most feasible waste management solution for rubber waste management which is the priority waste type in the tire manufacturing industry, representing greater closeness to the highest-ranked SWING weights on less public health and safety risks, high revenue generation and marketability, and less waste generation.
