Oman has witnessed a rapid growth in the generation of municipal solid waste due to the ever-increasing urbanization and expanding population. This escalation in the generation of municipal solid waste has burdened the existing waste management infrastructure and increased the carbon footprint of the sector. Therefore, the need of an integrated waste management system is rising in Oman and establishing waste-to-energy technologies is becoming an absolute necessity. Therefore, this study investigates the financial feasibility of incineration, gasification and anaerobic digestion technologies in the Muscat governorate of Oman. The potential cost and revenue streams during the economic life of waste-to-energy plants are estimated to evaluate the profitability of projects by a set of financial parameters. Incineration has emerged as the most profitable strategy with the positive net present value of 255 million USD compared to 169 and 97.9 million USD for anaerobic digestion and gasification, respectively. Furthermore, incineration offers higher energy potential at lower cost (0.06 USD/kWh) than gasification (0.11 USD/kWh) and AD (0.16 USD/kWh). However, AD plant turns out more favorable in terms of profitability index, payback period, and internal rate of return and levelized cost of waste, mainly due to the low investment cost. This study concludes that incineration stands out among all options because of the higher profitability, waste treating capacity, energy generation and carbon footprint savings. The sensitivity analysis reveals that change in carbon credit allowance affects the profitability of all waste-to-energy plants, whereas electricity tariff and capital investment affect only incineration and gasification.

阿曼苏丹国马斯喀特的废物转化能源技术用于城市固体废物管理的财务可行性

由于城市化和人口的不断增长，阿曼已经见证了城市固体废物产生的快速增长。城市生活垃圾产生量的不断增加给现有的废物管理基础设施增加了负担，并增加了该部门的碳足迹。因此，在阿曼，对综合废物管理系统的需求日益增加，建立废物转化为能源技术已成为绝对必要。因此，本研究调查了阿曼马斯喀特省焚化，气化和厌氧消化技术的财务可行性。据估计，垃圾发电厂的经济寿命期间潜在的成本和收入流可通过一组财务参数评估项目的盈利能力。焚化已成为最赚钱的策略，正净现值为2.55亿美元，而厌氧消化和气化分别为169和9790万美元。此外，与气化（0.11 USD / kWh）和垃圾焚化（0.16 USD / kWh）相比，焚烧能以更低的成本（0.06 USD / kWh）提供更高的能源潜力。但是，AD工厂在盈利指数，投资回收期，内部收益率和废物平均成本方面更有利，这主要是由于投资成本较低。这项研究得出的结论是，焚烧在所有选择中脱颖而出，因为它具有更高的盈利能力，废物处理能力，能源产生和碳足迹节省。敏感性分析表明，碳信用额度的变化会影响所有垃圾发电厂的盈利能力，
