摘要

发展中国家对食物垃圾(FW)的不当管理造成了环境和卫生问题,是对可持续发展的一大威胁。据预测,未来 10 年,全球厨余垃圾的产量将增加 33%,估计每年将产生 16 亿吨垃圾,造成 1.2 万亿美元的经济损失,其中 50%至 60%来自消费后来源。要实现可持续的废物管理,必须从线性经济转向循环经济,使废物成为燃料和化学品等新产品的资源。本研究汇编了 2010 年至 2024 年间发表的 119 项研究成果,对各种 FW 循环利用方案进行了深入研究。这些可能性包括三种热处理工艺--燃烧、热解和气化--可产生生物燃料和生物炭。此外,还研究了通过生物和生物化学过程将 FW 转化为生物燃料、生物肥料、木炭和生物塑料的可能性。这项研究的新颖之处在于,它强调采用分散的、针对特定地区的方法来管理包装废物,尤其是一次性塑料,并将家庭废物的价值提升与联合国的可持续发展目标(SDGs)联系起来。

A comprehensive review of food waste: composition, current management, thermal treatment, valorization into bioproducts and sustainable development goals linkages

The improper management of food waste (FW) in developing nations causes environmental and hygienic problems and is a major threat to sustainable development. It is projected that the production of FW will increase by 33% globally over the next 10 years, resulting in an estimated 1.6 billion tons of waste per year and an economic loss of $1.2 trillion, with between 50 and 60% coming from post-consumer sources. Moving from a linear to a circular economy, where waste is a resource for new products like fuels and chemicals, is essential to achieving sustainable waste management. The results of 119 studies published between 2010 and 2024 are compiled in this study, which offers a thorough examination of FW recycling options. These possibilities include the three thermal treatment processes—combustion, pyrolysis, and gasification—that can yield biofuels and biochar. The possibility of converting FW into biofuels, biofertilizers, charcoal, and bioplastics through biological and biochemical processes is also investigated. This study is novel in that it emphasizes decentralized, regionally-specific approaches to managing packaging waste, especially single-use plastics, and connects FW valorization to the sustainable development goals (SDGs) of the United Nations (UN).

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).
