The only way to dispose of municipal solid waste (MSW) in Oman is in engineered landfills without pre-treatment. An effective waste management system requires a reliable database of solid waste composition, properties, and energy content. Although investigating waste in landfills in Muscat Governorate is challenging and complex, it is essential. In this study, MSW from Muscat Governorate landfills is examined. The MSW samples were collected et al. Amerat and Barka landfills in 2020 in order to determine some of the importance of their physiochemical properties and the ratio of materials (food, plastic, and paper). It was found that approximately 50% of the weight of the disposed waste was recyclable. There were high levels of biodegradable organic material in MSW. In terms of moisture content, MSW ranged from 21.5 to 43.3%. Both the volatility and loss of ignition of MSW were high. It was found that the total oxide ratios ranged from 12.4 to 44.06%. The elemental analysis of Muscat MSW resulted in six chemical formulas for MSW with and without sulfur. Silica is the most influential oxide, followed by calcium oxide. The findings of this study indicate that almost half of Muscat's municipal solid waste can be recycled. Solid waste can be recycled to create renewable materials that can replace oil as a by-product of the recycling industry. Additionally, Muscat MSW has a high moisture content, which enables it to be composted and biodegraded. Moreover, waste-to-energy technologies are feasible due to their high-energy content.
阿曼处理城市固体废物 (MSW) 的唯一方法是在未经预处理的工程垃圾填埋场中进行。有效的废物管理系统需要可靠的固体废物组成、特性和能量含量数据库。尽管调查马斯喀特省垃圾填埋场的废物具有挑战性和复杂性，但这是必要的。本研究对马斯喀特省垃圾填埋场的 MSW 进行了研究。2020 年，在 Amerat 和 Barka 垃圾填埋场收集了 MSW 样本，以确定其某些物理化学性质和材料（食物、塑料和纸张）比例的重要性。结果发现，约 50%的处置废物是可回收的。MSW 中含有大量可生物降解的有机物质。就水分含量而言，MSW 的范围为 21.5%至 43.3%。MSW 的挥发性和燃烧损失都很高。发现总氧化物比从 12.4%到 44.06%不等。穆斯卡特 MSW 的元素分析得出了六个有硫和无硫的 MSW 化学公式。二氧化硅是最具影响力的氧化物，其次是氧化钙。本研究的结果表明，马斯喀特市近一半的城市固体废物可以回收利用。固体废物可以回收利用，创造可再生材料，可以替代石油作为回收行业的副产品。此外，马斯喀特 MSW 水分含量高，可进行堆肥和生物降解。此外，由于其高能量含量，废物转化为能源技术是可行的。
