Enormous amounts of vegetable residues are wasted annually, causing many environmental problems due to their high moisture and organic contents. In this study, the methane production potential of 20 kinds of typical leafy vegetable residues in China were explored using a unified method. A connection between the biochemical components and the methane yields of these vegetables was well established which could be used to predict biogas performance in practice. A high volatile solid/total solid (VS/TS) ratio and hemicellulose content exhibited a positive impact on the biogas yield while lignin had a negative impact. In addition, three kinetic models were used to describe the methane production process of these agro-wastes. The systematic comparison of the methane production potentials of these leafy vegetables shown in this study will not only serve as a reference for basic research on anaerobic digestion but also provide useful data and information for agro-industrial applications of vegetable residues in future work.
每年都有大量的蔬菜残余物被浪费，因其高含水量和高有机物含量而引发诸多环境问题。在本研究中，采用统一方法探究了中国20种典型叶菜类蔬菜残余物的甲烷生产潜力。这些蔬菜的生化成分与甲烷产量之间建立了良好的关联，可用于实际预测沼气性能。高挥发性固体/总固体（VS/TS）比和半纤维素含量对沼气产量有积极影响，而木质素则有负面影响。此外，使用了三种动力学模型来描述这些农业废弃物的甲烷生产过程。本研究中对这些叶菜类蔬菜甲烷生产潜力的系统比较，不仅将为厌氧消化的基础研究提供参考，还将为未来工作中蔬菜残余物的农业工业应用提供有用的数据和信息。
