“…For instance, Feng and colleagues [22] evaluated the influence of different I:S ratios ranging from 1:1 to 1:6 on biogas production from vinegar residue. In another study, biochemical methane potential was studied for thickened sludge at three I:S ratios of 1:1, 1:3 and 1:8 [23].…”

Anaerobic batch experiments were conducted at mesophilic temperatures to investigate the possibility of biogas recovery from tannery sludge originating from a tannery wastewater treatment process. According to preliminary findings, the highest biogas yield was obtained as 0.172 L biogas/g VS added within an inoculum to substrate (I:S) ratio of 1:10 and at solids content of 10.6 %. The highest methane yield of 0.089 L CH 4 /g VS added was achieved within an I:S ratio of 1:2 during the experiments. Relatively lower biogas and methane yields could be attributed to the low organic content of raw sludge cake. Potential inhibitors of anaerobic digestion, such as heavy metals, particularly chromium, chloride and sulfate available in raw sludge cake did not seem to influence the process adversely. Despite lower methane yields, it seemed possible to employ anaerobic digestion process for stabilization and energy recovery from tannery sludge, since the biogas obtained could further be used in the wastewater treatment plant as a source of energy. Co-digestion of tannery sludge with another type of substrate available (e.g., tannery solid wastes) can be an alternative to achieve higher biogas and methane yields considerably.

“…Anaerobic digestion (AD) as a means of taking advantage of solid organic waste to produce energy-rich biogas and reduce pollution has gained more and more attention. It has been proven in previous research that AD technology could be applied for vinegar residue which represents a praiseworthy solution to deal with vinegar residue and a fascinating option for producing renewable energy (Feng et al, 2013), while continuous AD of vinegar residue still rarely reported.…”

h i g h l i g h t sAnaerobic digestion of vinegar residue was investigated in continuous condition. CSTR showed a stable methane yield of 232.75 mL g vs À1 at OLR of 2.5 g vs L À1 d À1. Effluent recirculation significantly improved the stability of the AD system. a r t i c l e i n f o , were used. The highest volumetric methane productivity of 581.88 mL L À1 was achieved at OLR of 2.5 g vs L À1 d À1. Effluent reflux ratio was set as 50%, the results showed that effluent recirculation could effectively neutralize the acidity of vinegar residue, raise the pH of the feedstock, and enhance the buffering capacity of the AD system. Anaerobic digestion of vinegar residue could be a promising way not only for converting this waste into gas energy but also alleviating environmental pollution which might be useful for future industrial application.

“…The Buswell equation has been used to predict the BMP of various substrates. For example, the BMP of lipid and cellulose were estimated at 1 018 L kg -1 and 415 L kg using Equation 5 (Feng et al, 2013). The modified Dulong formula can also be applied to estimate the theoretical maximum CH 4 yields of all types of wastes .…”
