The Sultanate of Oman faces challenges, like rapid growth of waste generation, which calls for an optimum waste management strategy. Oman has witnessed the production of 1.5m t of municipal solid waste in 2012, which is expected to elevate to 1.89m t in 2030. This rapid increase needs to be tackled to reduce the generation rates along with the environmental impacts. Currently, there are no treatment facilities in Oman other than limited recycling, and therefore dumping waste into the landfill is the only ultimate way to dispose solid waste. Hence, this study is an initiative to improve the waste managing system in Oman by proposing optimum waste-to-energy technology using an analytical hierarchy process, manually and through expect choice software as well. In the present study, the identified important parameters were considered in an analytical hierarchy process model to rank the waste-to-energy technology alternatives. Based on the survey conducted, the most important criteria were environmental and economic, with the local priority vector of 0.400 and 0.277, respectively. This research concludes that the most suitable waste-to-energy technology for Oman, on the basis of the identified criteria, is anaerobic digestion followed by fermentation and incineration, which will help to reduce the amount of waste, greenhouse gas emissions and developing and maintaining costs of landfills.
阿曼苏丹国面临着挑战，如垃圾产生的快速增长，这需要一个最佳的废物管理策略。阿曼在 2012 年产生了 150 万吨的城市固体废物，预计到 2030 年将增加到 189 万吨。为了减少垃圾的产生率和减少对环境的影响，必须解决这一快速增长的问题。目前，阿曼除了有限的回收利用外，没有其他处理设施，因此将废物倾倒到垃圾填埋场是处理固体废物的唯一最终方法。因此，本研究旨在通过使用层次分析法，手动和通过期望选择软件提出最佳的废物转化为能源技术，来改善阿曼的废物管理系统。在本研究中，确定的重要参数被考虑在层次分析法模型中，以对废物转化为能源技术的替代方案进行排名。根据调查，最重要的标准是环境和经济，本地优先向量分别为 0.400 和 0.277。本研究得出的结论是，基于确定的标准，阿曼最适合的废物转化为能源技术是厌氧消化，其次是发酵和焚烧，这将有助于减少垃圾量、温室气体排放以及开发和维护垃圾填埋场的成本。
