The Sustainable Development Goals (SDGs) play an essential role, emphasizing responsible resource use, production, and consumption, including waste management. In addition, SDG 3, 7, 11, 12, 13 are directly/indirectly related to This study aims determine a suitable waste-to-energy (WtE) technology in Chittagong City, Bangladesh, focusing on cleaner technology. Anaerobic digestion, gasification, incineration, landfill gas (LFG) recovery were considered as possible alternatives. Technical, economic, environmental, social issues have been necessary criteria for evaluation. An analytical hierarchy process was applied rank these technologies based stakeholders’ perceptions. found that anaerobic digestion (AD) ranked first, receiving 38% of overall weight. second preferred is LFG (27%). Gasification incineration stood at third fourth, respectively (21% 14%). According sensitivity study, the decision only sensitive economy. will become most favoured solution WtE conversion if economy prioritizes more than 38%. Subsequently, this study’s findings help achieve Bangladesh’s agenda.
