Anaerobic co-digestion of food waste, cow dung, and sludge solution is experimented in the presence of calcium peroxide (CaO₂) as the catalyst to produce hydrogen and methane as a source of renewable energy. The substrate to inoculum ratios (v/v) of 1:1(S1), 1:2(S2), 1:3(S3), 1:4(S4) and 1:5(S5) are investigated in separate fermentative and methanogenic reactors. The result from the fermentative reactors indicate maximum hydrogen concentration of 26.34% with cumulative yield of 114.1 mL/g total solid (TS) in S3 compared to the other samples. Methanogenic reaction shows the highest methane concentration of 54.13% in S3. The highest daily (average) and cumulative biogas yield of 5.36 mL/g TS and 201.9 mL/g TS respectively are identified in S3. A maximum carbon dioxide concentration of 63.11% is found in S1. Overall, the substrate to inoculum ratio of 1:3 is spotted to be optimal for effective hydrogen and methane production during the anaerobic co-digestion process.

在有过氧化钙（CaO _2）的条件下对食物残渣，牛粪和污泥溶液进行厌氧共消化）作为产生氢气和甲烷作为可再生能源的催化剂。在单独的发酵罐中研究了底物与接种物的比例（v / v）1：1（S1），1：2（S2），1：3（S3），1：4（S4）和1：5（S5）和产甲烷反应器。发酵反应器的结果表明，与其他样品相比，S3中的最大氢浓度为26.34％，累积产率为114.1 mL / g总固体（TS）。产甲烷反应显示S3中最高的甲烷浓度为54.13％。在S3中，日最高（平均）和累计沼气产量分别为5.36 mL / g TS和201.9 mL / g TS。在S1中发现最大二氧化碳浓度为63.11％。总体而言，发现底物与接种物的比例为1：3是厌氧共消化过程中有效产生氢气和甲烷的最佳方法。
