“…For nitrogen, the biogas production is directly proportional to nitrogen concentration. Similar results were achieved by Singh et al (2010) which reported that the organic matter is reduced and converted to methane during anaerobic digestion of cattle waste slurry as substrate. The biogas produced was analyzed by gas chromatography, and substantial amount of methane was found in samples containing 4.5 mg/mL of nitrate as electron acceptor (90 %, Fig.…”

“…In this case, the highest biogas production was obtained 9 days after incubation. The biogas production is comparable to those reported by Singh et al (2010) and Jackson-Moss and Duncan (1990), using cattle waste slurry and domestic sewage as the growth medium, respectively (0.10-0.51 L/L Day; this work 0.2-0.43 L/L Day), but lower compared with a mixed sludge that contains tannery sludge (1.49 L/L Day; Di Berardino and Martinho 2009). The least amount of biogas generated was in the treatment with the intermediate C/N ratio of 8, where very little or no amount of biogas was detected in any of the replicates throughout the incubation period.…”

“…Samples were sent to different laboratories to validate our results. Quality of biogas could be considered higher than biogas production from sludge of a tannery sludge or municipal wastewater treatment plants reported elsewhere (Adl et al 2012;Arshad et al 2011;Di Berardino and Martinho 2009;Kalloum et al 2011;Singh et al 2010;Zupančič and Jemc 2010). The increase in methane production is related to the addition of nitrate in the system.…”

Effluents from the leather processing generally are discharged into rivers or are used to irrigate farmland. The biogas production from the digestion of sludge produced could be used as alternative sources for energy and power generation. A study was carried out to examine the effects of various electron acceptor amendments on biogas production from Mexican tannery sludge. Two bench scale experiments were performed: The first experiment used different electron acceptors (nitrate, iron and sulfate) and three different levels for each variable (4.5, 9.0 and 13.5 mg/mL); in the second only urea was used as a nitrogen source with three carbon/nitrogen ratios (6.0, 8.0 and 11). It was found that the reactors with nitrate as electron acceptor (4.5 mg/mL) generated the most biogas (200 mL of biogas accumulated in 25 days). Similarly, the reactors with the lower ratio of carbon/nitrogen (6.0) produced larger biogas production (131.50 ± 19.1 mL of biogas) in a shorter period of time (9 days). The results also showed that the addition of glucose did not significantly influence the production of biogas.

“…Initially, 500 ml of microbial slurry along with 10% cow dung is taken for 2 kg of waste in the digester. Cow dung is efficient for this process of slurry formation as it comprises bacteria called "Estinia Fetida" which is responsible for the enhancement of forth formation process which is the initial stages to indicate the biogas production (Singh et al, 2010). After that, the ratios taken were 70% kitchen waste along with 20 % of microbes in aqueous form.…”

Biogas is a non-exhaustible of energy which can be formed from anaerobic fermentation of different types of biodegradable waste such as food waste, plant waste, animal waste sewage and other organic waste. The typical composition of Biogas includes CH4 (50–70%) which is responsible for maximum energy content along with CO2 (25–50%) that can be collected, stored and supplied. Biogas acts as a multipurpose and an eco- friendly sustainable resource of energy which can be utilized for cooking, electricity generation, lightning, heating etc. Biodegradable waste specifically produced in large amounts as a kitchen waste. In modern society, the solid waste per capita has been consistently increasing as of increase in population and change in socio-economic-cultural habits. The biogas production through the kitchen waste thereof provides a solution of disposal of solid waste. The bio gas production through anaerobic degradation pathways can be controlled and enhanced with the help of certain microorganisms and advancements of new technologies. In this research work, an attempt is being made to produce the biogas from kitchen and food waste collected from hostel mess of Chitkara University, Punjab and a novel method of production of microorganism has been also proposed for fast degradation of waste. Under this project, a survey for the estimation of daily production of organic waste from hostel mess has also been done for fifteen day.

“…Jain, Dinesh kumar (2000), [6] carried studies on cattle dung and their residues insemination with kitchen waste and found that the increased biogas production using microbial stimulants. Ranjeet Singh, S. K. et.al [7]collected inocula from four different sources such as Jajmau tannery waste treatment plant (ITW), Jajmau municipal waste treatment (IMW), Unnao distillery (IDW) and batch reactor and carried studies for the generation of waste. Jong Won Kang et al (2010) [8]studied the On-site Removal of H2S from Biogas Produced by Food Waste using an Aerobic Sludge Bio filter for Steam Reforming Processing.…”
