“…2. In terms of biogas yield this corresponded to a range of 350 to 438 mL/g VS. Biogas yield values closes to these finding were reported by recent works for both food wastes and leachate codigestion with sewage sludge [6,46]. Results similar to our finding were also reported by [48] for which biogas yield varied from 233 to 344 mL CH 4 /g VS for leachate wastewater ratio from 1:9 to 5:5 with maximum yield at 3:7 ratio.…”

“…Recently an energetic yield increase up to 80% was achieved with food waste leachate as co-substrate [22]. Similar recent works in which different kinds of food wastes leachates were codigested with wastewaters using different ratios confirmed the hypothesis that co-anaerobic digestion is more likely to realize bio-gasification than single wastewater anaerobic digestion [6]. The mixing ratios of food waste leachate that produces the highest methane yield varied in a large range depending on both wastewaters and leachate characteristics and origin [23].…”

“…Anerobic codigestion of leachate has recently gained interest using different substrates, effluents and technolgies [1][2][3]. Leachates, particulary the young ones, are more and more considered as a source of energy and the most emerging reflexion in that field is associated to food waste and landfill leachates and wastewater codigestion in ordre to improve anaerobic wastewater plant efficiency and energy dependence [4][5][6].…”

The Biochemical Methane Potential (BMP) of fresh leachate and domestic wastewaters codigestion was determined by laboratory Bach Tests at 35ºC over a period of 90 d using a wide range of leachates volumetric ratios from 0% to 100%. To simulate wastewaters plant treatment step, all the ratios were first air stripped for 48 h before anaerobic incubation. The kinetic of biogas production was assessed using modified Gompertz model and exponential equation. The results obtained showed that cumulative biogas production was insignificant in the case of wastewaters monodigestion while the codigestion significantly improves the BMP. Air stripping pretreatment had positive effect on both ammonium concentration and volatiles fatty acids with reduction up to 75% and 42%, respectively. According to the Modified Gompertz model, the optimal anaerobic co-digestion conditions both in terms of maximal biogas potential, start-up period and maximum daily biogas production rate, could be achieved within large leachate volumetric ratios from 25% to 75% with a maximum BMP value of 438.42 mL/g volatile solid at 50% leachate ratio. The positive effect of codigestion was attributed to a dilution effect of chemical oxygen demand and volatile fatty acid concentrations to optimal range that was between 11.7 to 32.3 gO2/L and 2.1 to 7.4 g/L, respectively. These results suggested that the treatment of fresh leachate by their dilution and co digestion at wastewaters treatment plants could be a promising alternative for both energetic and treatment purposes.

“…Sludge can be separated into organic and inorganic sludge, and organic sludge can be highly reduced by incineration [15]. Currently, the management of sewage sludge produced from wastewater treatment plants is one of the most serious challenges in biological wastewater treatment.…”

“…In contrast, agro-wastes contain a high percentage of carbon and a low percentage of nitrogen (high C/N ratio). Different types of agro-wastes can be used in admixture with sewage sludge, such as rice straw [17], wheat straw [15] and municipal solid wastes [8]. Co-digestion of sewage sludge and decanter cake is considered the best solution for enhancing methane yield.…”
