Abstract

Food waste production reaches actually about 1.3 billion tonnes per year, corresponding to the emission of 3.3 billion tonnes equivalent of CO₂, thus calling for improved recycling. Here we review food waste conversion into energy and products such as biohydrogen, biogas, biofuel, biodiesel, biochar, bioplastics, fertilizers, animal feed, organic acids, enzymes, and proteins. Food waste can be treated by incineration, pyrolysis, composting, anaerobic digestion, hydrothermal carbonization, and landfilling. Properties of food waste influence the efficiency of conversion.

将厨余垃圾转化为能源和增值产品：综述

食物垃圾的实际年产量约为 13 亿吨，相当于排放 33 亿吨二氧化碳当量，因此需要改进回收利用。在此，我们将探讨如何将厨余垃圾转化为能源和产品，如生物氢、沼气、生物燃料、生物柴油、生物炭、生物塑料、肥料、动物饲料、有机酸、酶和蛋白质。厨余垃圾可以通过焚烧、热解、堆肥、厌氧消化、热液碳化和填埋等方式进行处理。厨余垃圾的特性会影响转化效率。

期刊介绍： Environmental Chemistry Letters explores the intersections of geology, chemistry, physics, and biology. Published articles are of paramount importance to the examination of both natural and engineered environments. The journal features original and review articles of exceptional significance, encompassing topics such as the characterization of natural and impacted environments, the behavior, prevention, treatment, and control of mineral, organic, and radioactive pollutants. It also delves into interfacial studies involving diverse media like soil, sediment, water, air, organisms, and food. Additionally, the journal covers green chemistry, environmentally friendly synthetic pathways, alternative fuels, ecotoxicology, risk assessment, environmental processes and modeling, environmental technologies, remediation and control, and environmental analytical chemistry using biomolecular tools and tracers.
