Abstract

The generation of food waste (FW) is increasing at an alarming rate, contributing to a total of 32% of all the waste produced globally. Anaerobic digestion (AD) is an effective method for dealing with organic wastes of various compositions, like FW. Waste valorization into value-added products has increased due to the conversion of FW into biogas using AD technology. A variety of pathways are adopted by microbes to avoid unfavorable conditions in AD, including competition between sulfate-reducing bacteria and methane (CH4)-forming bacteria. Anaerobic bacteria decompose organic matter to produce biogas, a digester gas. The composition depends on the type of raw material and the method by which the digestion process is conducted. Studies have shown that the biogas produced by AD contains 65-75% CH4 and 35-45% carbon dioxide (CO2). Methanothrix soehngenii and Methanosaeta concilii are examples of species that convert acetate to CH4 and CO2. Methanobacterium bryantii, Methanobacterium thermoautotrophicum, and Methanobrevibacter arboriphilus are examples of species that produce CH4 from hydrogen and CO2. Methanobacterium formicicum, Methanobrevibacter smithii, and Methanococcus voltae are examples of species that consume formate, hydrogen, and CO2 and produce CH4. The popularity of AD has increased for the development of biorefinery because it is seen as a more environmentally acceptable alternative in comparison to physico-chemical techniques for resource and energy recovery. The review examines the possibility of using accessible FW to produce important value-added products such as organic acids (acetate/butyrate), biopolymers, and other essential value-added products.

协同厌氧消化食物垃圾以提高沼气和增值产品的产量:战略、挑战和技术经济分析。
厨余垃圾(FW)的产生量正以惊人的速度增长,占全球垃圾总量的 32%。厌氧消化(AD)是处理各种成分的有机废物(如厨余垃圾)的有效方法。由于使用厌氧消化技术将 FW 转化为沼气,废物价值转化为增值产品的情况有所增加。在厌氧消化(AD)过程中,微生物采用多种途径来避免不利条件,包括硫酸盐还原菌和甲烷(CH4)形成菌之间的竞争。厌氧细菌分解有机物产生沼气,即沼气池气体。其成分取决于原料的类型和消化过程的方法。研究表明,厌氧发酵产生的沼气含有 65-75% 的甲烷(CH4)和 35-45% 的二氧化碳(CO2)。Methanothrix soehngenii 和 Methanosaeta concilii 是将醋酸盐转化为甲烷和二氧化碳的物种。白云甲烷杆菌、热自养甲烷杆菌和树木甲烷杆菌是利用氢气和二氧化碳产生 CH4 的菌种。甲酸甲烷杆菌(Methanobacterium formicicum)、冶金甲烷杆菌(Methanobrevibacter smithii)和伏特甲烷球菌(Methanococcus voltae)是消耗甲酸盐、氢气和二氧化碳并产生 CH4 的菌种。在发展生物精炼方面,厌氧消化(AD)越来越受欢迎,因为与回收资源和能源的物理化学技术相比,厌氧消化(AD)被认为是一种更环保的替代技术。本综述探讨了利用可获得的 FW 生产重要增值产品的可能性,如有机酸(醋酸/丁酸)、生物聚合物和其他重要增值产品。
