Abstract

Solid waste management is a global issue exacerbated by rapid population growth, urbanization, and economic development. Municipal solid waste, particularly food waste (FW), poses significant environmental, social, and financial challenges. In this study, we first review the waste management status of the State of Kuwait which is considered one of the world’s highest waste generating countries. Kuwait possesses a hydrocarbon-based economy that relies solely on crude oil exports for its financial stature. FW management options that can serve the country, in light of technological advances are also reviewed, namely for hydrogen (H2) production. The country can take advantage of H2 economy experiences to reduce its environmental print and diversify its economy too. This was proven by a case study that we present considering a functional unit of one ton of FW for H2 production in a life cycle analysis fashion. Anaerobic digestion with energy recovery taking dark fermentation as a viable route has proven to be most effective herein.

科威特国氢回收背景下的食物垃圾价值评估
固体废物管理是一个全球性问题,因人口快速增长、城市化和经济发展而加剧。城市固体废物,特别是食物废物,构成了重大的环境、社会和财政挑战。在本研究中,我们首先回顾了科威特的废物管理状况,科威特被认为是世界上废物产生最多的国家之一。科威特拥有以碳氢化合物为基础的经济,其财政地位完全依赖原油出口。根据技术进步,还审查了可以为国家服务的FW管理方案,即氢气(H2)生产。该国可以利用氢气经济的经验来减少其环境影响并使其经济多样化。我们通过一个案例研究证明了这一点,该案例研究以生命周期分析的方式考虑了一吨FW用于H2生产的功能单元。以暗发酵为途径的能量回收厌氧消化已被证明是最有效的。

期刊介绍: The Journal of Material Cycles and Waste Management has a twofold focus: research in technical, political, and environmental problems of material cycles and waste management; and information that contributes to the development of an interdisciplinary science of material cycles and waste management. Its aim is to develop solutions and prescriptions for material cycles. The journal publishes original articles, reviews, and invited papers from a wide range of disciplines related to material cycles and waste management. The journal is published in cooperation with the Japan Society of Material Cycles and Waste Management (JSMCWM) and the Korea Society of Waste Management (KSWM).
