“…An excessively alkaline pH can lead to the disintegration of microbial granules and subsequent failure of the digestion process (Sandberg et al, 1992). Anaerobic digestion of two or more substrates increased biogas or methane yield as it has been reported previously that high methane production of 603 mL CH4/g VS was obtained in the co-digestion of a mixture of 70% manure, 20% food waste and 10% sewage sludge at the OLR of 1.2 g-VS/L day (Marañón et al, 2012). Co-digestion of animal manure with agricultural residues also has been reported previously (Callaghan et al, 2002;Kaparaju & Rintala, 2005) and the co-digestion of poultry manure with the other waste such as food and agricultural waste that has the potential for methane production.…”

Food waste with high carbohydrate content is considered as a suitable substrate for fermentation of methane gas. In this study, co-digestion of poultry manure (PM) and food waste (FW) was used. Response surface methodology (RSM) and artificial neural network (ANN) were applied to optimize parameters of co-digestion of PM and FW at different ratios, initial pH values and temperatures. A comparative analysis was done using RSM and ANN in a predictive model of the experimental data obtained in accordance with the central composite design. The combined effects of the independent variables (ratio, pH and temperature) as the most significant parameters of methane fermentation of PM and FW were investigated. Optimization using RSM and ANN showed a good fit between the experimental and the predicted data as elucidated by the coefficient of determination with R 2 values of 0.991 and 0.998, respectively. Quadratic RSM predicted the maximum methane yield to be 537 mL CH 4 /g VS at the optimal conditions; ratio 80:20 (PM : FW); temperature 35 °C; and initial pH 7.11. The maximum predicted methane yield by the ANN model was 535.82 mL CH 4 /g VS at the following conditions; ratio of poultry manure to food waste 80:20; temperature 35 °C; and pH 7.00. The verification experiments successfully produced 538 mL CH 4 /g VS within 14 days of incubation. These experiments indicated that the developed model was successfully used to predict the fermentable methane production.

“…1b. The higher biogas production of 0.7 L g -1 VS removed is achieved by codigesting organic kitchen waste (OKW) and cattle manure (OKW:CM mixing ratio 75:25) (Aragaw et al 2013), but also cattle manure, food waste with glycerin (87:10:3) (Castrillon et al 2013) and cattle manure, food waste, sewage sludge (70:20:10 TS concentration around %4) (Marañón et al 2012) give very high methane generation of 0.64, 0.61 L g -1 VS with 93 % COD, 53 % VS removal, respectively. In a field study, biogas yield of 0.41 and 0.47 L g -1 VS loaded is conducted by co-digesting CM, chicken manure without or with maize silage around 50 % VS reduction in mesophilic condition (Yangin-Gomec and Ozturk 2013).…”

This literature review surveys the previous and current researches on the co-digestion of anaerobic processes and examines the synergies effect of co-digestion with cattle manure. Furthermore, this review also pays attention to different operational conditions like operating temperature, organic loading rate (OLR), hydraulic retention time (HRT), chemical oxygen demand (COD) and volatile solid (VS) removal efficiency and biogas or methane production. This review shows that anaerobic mono-digestion of cattle manure usually causing poor performance and stability. Anaerobic studies were generally performed under mesophilic conditions maintained between 35 and 37°C. Organic waste loading rate generally ranges from 1 to 6 g VS-COD L -1 day -1 stable condition in anaerobic digester. Generally, studies show that HRT for co-digestion of fruit-vegetables waste and industrial organic waste appears to exceed 20 days. However, the anaerobic co-digestion process is generally operated at HRT of between 10 and 20 days. VS and COD removal efficiency usually reaches up to 90 % due to codigestion with different type organic waste. Methane-biogas production is generally obtained between 0.1 and 0.65 L CH 4 -biogas g -1 VS.

“…Co-digestion has better nutritional balance and digester work so the ability to produce biogas is higher [4]. Many studies have developed codigestion methods such as biogas production from industrial waste beer and cow dung [5], co-digestion of livestock manure with food and sludge waste in order to increase biogas production [6], co-digestion of Thaihu algae and waste food waste in kitchens [7], anaerobic co-digestion of water hyacinth and sheep dung [8] and many others. Materials used as the main ingredients are generally derived from livestock waste and food industry waste.…”

Abstract. Biogas will be produced from a single organic substrate and controlled the ratio of carbon nitrogen by added inorganic nitrogen substances. The study has been tried to combine substrates from industrial tapioca industrial wastewater with tofu industrial wastewater. The experiments were carried out in batch anaerobic digesters with a C/N ratio range of 20 -30 and variation of microbial sludge from cow rumen, anaerobic sludge of tofu wastewater treatment plant (WWTP) and anaerobic sludge of tapioca WWTP. The ratio of C/N in the range of 20-30 didn't significant effect on the volume of biogas production. The microbial from cow rumen gives the best biogas production performance. Biogas yield is 2,199 liter per kg COD.
