Sixteen data sets (two of which were measured in this study) with a combined total of 145 measurements of ultimate methane yield (UMY) during mono- and co-digestion of ternary biomass mixtures were used to assess impact of co-digestion on the relative change in UMY (ΔUMY) as a function of biomass mix composition. The data involved 9 biomass materials (brewery spent grains, chicken manure, cow manure, fresh grass clippings, pig manure, primary sewage sludge, vegetable food waste, wheat straw, and rice straw). Results of the assessment shows that co-digestion in 85% of yields positive values of ΔUMY regardless of the biomass materials used, however, a smaller fraction (15%) resulted in negative ΔUMY during co-digestion. The data further indicate that for each set of ternary biomass material mixtures there exists an optimal biomass mix composition at which ΔUMY is at a maximum. Statistical analyses based on the data used here indicate that the maximum value of ΔUMY (ΔUMY) is always positive regardless of biomass materials being co-digested.
使用了16个数据集（其中两个是本研究中测量的），这些数据集总共包含145次三元生物质混合物单消化和共消化过程中最终甲烷产量（UMY）的测量值，以评估共消化对作为生物质混合组成函数的UMY相对变化（ΔUMY）的影响。数据涉及9种生物质材料（啤酒糟、鸡粪、牛粪、鲜草屑、猪粪、初级污水污泥、蔬菜食物垃圾、小麦秸秆和稻草）。评估结果表明，无论使用何种生物质材料，85%的共消化产生了正值的ΔUMY，然而，较小比例（15%）的共消化在共消化过程中导致了负值的ΔUMY。数据进一步表明，对于每组三元生物质材料混合物，都存在一个最佳的生物质混合组成，此时ΔUMY最大。基于此处使用的数据进行的统计分析表明，无论共消化的生物质材料如何，ΔUMY的最大值（ΔUMY）始终为正。
