“…For F2, the total methane yield recorded an 88% increase, which was the highest value among all treatments (Table 3). These findings are comparable with the outcomes of Vivekanand et al, as they achieved an increase of methane yields up to 84% by combining manure with fish ensilage compared to the individual substrates [61].…”

“…These results confirm the importance of the nutrient mixing ratio in substrates, which affects the metabolic activity of the microflora in the digesters as stated by Rughoonundun et al [60]. It was noted that utilizing single substrates for AD could be inefficient because of various reasons including insufficient nutrients accessible for the microbial community, the degree of biodegradability, and the optimization of C/N ratio (the latter is demonstrated below) [61].…”

Methane Production from Alginate-Extracted and Non-Extracted Waste of Laminaria japonica: Anaerobic Mono- and Synergetic Co-Digestion Effects on Yield

This study investigated the potentiality of methane production from alginate-extracted (AEWLJ) and non-extracted (NAEWLJ) waste of Laminaria japonica through batch anaerobic fermentation in mono- and co-digestion with rice straw (RS) at different mixing ratios. Optimal C/N ratio was demonstrated, and system stability was monitored in terms of the total ammonia nitrogen, total volatile fatty acids, and pH throughout the digestion period. The results show that the combination of AEWLJ/RS at 67% mixing ratio generated the highest biogas yield of 247 NmL/gVS, which was 36% higher than the AEWLJ alone. The synergetic effect was clearly observed leading to an increase in the total methane yield up to 78% and 88%, respectively, for arrays of AEWLJ/RS and NAEWLJ/RS. The kinetic model showed a high coefficient of determination (R2 ≥ 0.9803) when the modified Gompertz model was applied to predict methane production. These outcomes support the possibility of an integrated biorefinery approach to attain value-added products in order to achieve circular economies.

“…On the contrary, some studies have reported opposing results. Vivekanand et al [42] had mixed three different substrates, including whey (W), manure (M), and fish ensilage (FE); however, they did not find any synergistic effects on methane yield, as compared to the mixture of two substrates. The authors observed the best results (566 mL CH 4 /g VS) with a mixing ratio of W 10:M 10:FE 80, while the best results with all mixture were found to be at M 15:FE 85 (729 mL CH 4 /g VS).…”

Evaluation of Anaerobic Co-Digestion to Enhance the Efficiency of Livestock Manure Anaerobic Digestion

2019

In this paper, the anaerobic co-digestion of three different organic wastes, including livestock manure, slaughterhouse waste, and agricultural by-products (ABs), was carried out to enhance the efficiency of mono-digestion of livestock manure. The characteristics of co-digestion were evaluated at different mixing ratios. The experiment was performed using the Batch test and was divided into two parts. The first experimental section (EXP. 1) was designed to evaluate the seasonal characteristics of ABs, which are the different ratios of fruits and vegetables, where the mixing ratio of spring (fruits:vegetables = 3:7) showed the highest biogas yield (0.24 m3/kg volatile solids). The second experiment (EXP. 2) was conducted by using ABs in the ratio that gave the highest biogas yield in EXP. 1 in combinations of three wastes livestock manure, slaughterhouse waste, and ABs. The highest CH4 yield was 0.84 m3/kg volatile solids (VS), which was obtained with a mixing ratio that had even amounts of the three feedstocks. In addition, the results of the second biochemical methane potential test, which assessed the digestive efficiency according to the mixing ratio of the three types of organic waste, showed that the CH4 production rate of the merged digestion was approximately 1.03–1.29 times higher than that of the mono-digestion of livestock manure. The results of our experiment were verified using the modified Gompertz model, the results of which were relatively similar to the experimental results.

“…Além disso, de acordo com Vivekanand et al (2018), a digestão anaeróbica de substratos únicos pode ser ineficiente devido a desequilíbrios na relação C/N, grau de biodegradabilidade e/ou devido à falta de nutrientes necessários à comunidade microbiana. Assim, o emprego de mais substratos na co-digestão anaeróbica, além de proporcionar melhores rendimentos na produção de energia sustentável, auxilia no tratamento final de diversos resíduos, reduzindo principalmente alto teores de matéria orgânica e promovendo sua disposição final a fim de controlar a poluição ambiental (Tsapekos et al, 2017).…”
