This study presents a preliminary assessment of biodiesel production from waste sources available in the Kingdom of Saudi Arabia (KSA) for energy generation and solution for waste disposal issues. A case study was developed under three different scenarios: (S1) KSA population only in 2017, (S2) KSA population and pilgrims in 2017, and (S3) KSA population and pilgrims by 2030 using the fat fraction of the municipal solid waste. It was estimated that S1, S2, and S3 scenarios could produce around 1.08, 1.10 and 1.41 million tons of biodiesel with the energy potential of 43423, 43949 and 56493 TJ respectively. Furthermore, annual savings of US $55.89, 56.56 and 72.71 million can be generated from landfill diversion of food waste and added to the country's economy. However, there are challenges in commercialization of waste to biodiesel facilities in KSA, including waste collection and separation, impurities, reactor design and biodiesel quality.
本研究对沙特阿拉伯（KSA）可用的废物资源生产生物柴油进行了初步评估，以用于能源生产和解决废物处理问题。根据三种不同情景（S1、S2 和 S3）进行了案例研究：（S1）仅 2017 年的沙特阿拉伯人口；（S2）2017 年的沙特阿拉伯人口和朝圣者；（S3）到 2030 年的沙特阿拉伯人口和朝圣者，使用城市固体废物中的脂肪部分。据估计，S1、S2 和 S3 情景可分别生产约 108 万吨、110 万吨和 141 万吨生物柴油，相应的能源潜力分别为 43423 TJ、43949 TJ 和 56493 TJ。此外，通过将食物垃圾从垃圾填埋场转移出去，每年可节省 5589 万美元、5656 万美元和 7271 万美元，并可将其添加到该国的经济中。然而，在沙特阿拉伯将废物转化为生物柴油的商业化方面存在挑战，包括废物收集和分离、杂质、反应器设计和生物柴油质量。
