Abstract

Resource shortages, energy scarcity, and environmental degradation pose significant challenges to sustainable development, while waste-to-bioenergy technology provides a promising solution to overcome the above challenge. To quantify the associated socioeconomic impact, food waste in Singapore was investigated as a model case to evaluate the resource potential, energy security, and environmental sustainability of the food waste derived biobutanol. Results showed that positive policy interventions reduced food waste generation, but food waste remained reliable bioresource to produce biobutanol despite fluctuations, reducing the reliance of energy system on geo-resources such as petroleum. Biobutanol generated from food waste could function as part of natural gas stock or fulfill the transport energy needs previously satisfied by natural gas, improving energy diversity and security, in addition to decarbonizing energy system by food waste valorization and fossil fuel substitution. Analogous results could be extended to other countries with food waste issues. In conclusion, the waste-to-energy scenario is a sustainable option for food waste management, which synergized energy security, circular economy and decarbonization to reconstruct a sustainable resource-energy-environment nexus with a benign technology node.

将食物垃圾转化为生物丁醇的资源-能源-环境关系：资源回收、能源安全和温室气体减排的潜力

资源短缺、能源短缺和环境退化对可持续发展构成重大挑战，而废物转化为生物能源技术为克服上述挑战提供了一个有希望的解决方案。为了量化相关的社会经济影响，以新加坡的食物垃圾为例进行了研究，以评估食物垃圾衍生生物丁醇的资源潜力、能源安全和环境可持续性。结果表明，积极的政策干预减少了食物垃圾的产生，但尽管有波动，食物垃圾仍然是生产生物丁醇的可靠生物资源，减少了能源系统对石油等地质资源的依赖。从食物垃圾中产生的生物丁醇可以作为天然气储备的一部分或满足以前由天然气满足的运输能源需求，改善能源多样性和安全性，除了通过食物垃圾增值和化石燃料替代使能源系统脱碳之外。类似的结果可以推广到其他存在食物浪费问题的国家。综上所述，垃圾焚烧能源方案是一种可持续的食物垃圾管理方案，它将能源安全、循环经济和脱碳协同起来，以良性的技术节点重建可持续的资源-能源-环境关系。

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
