This research was to investigate the potential of biogas production from the co- digestion of canteen wastewater and food waste. Batch experiments were carried out under various substrate ratios1 : 1 : 0, 1 : 1 : 1, 1 : 1 : 2, 1 : 2 : 1, 2 : 1 : 1, 2 : 2 : 1, 3 : 2 : 1, 4 : 2 : 1, 6 : 5 : 1, 8 : 5 : 1, 10 : 3 : 1, 10 : 4 : 1 and 10 : 5 : 1 (canteen wastewater : swine manure : food residue waste) at room temperature. The biogas production was carried for a retention period of 7 days to investigate suitable mixing ratio. The suitable ratio was tested in a plastic container 200 liter with bath and fed-batch experiment for a retention period of 45 days. The results revealed that fermentation slurry mixing ratio of 1 : 2 : 1 was found to be optimum, which gave the methane production with composition 47.34-61 %CH4. The biogas yield and thermal energy were 88.86 L/day and 69 kcal respectively.These primary results indicated the significance of co-digestion of canteen wastewater with food waste for biodegradation and biogas production.

This paper aims at finding the effect of co-digestion of cow dung and food waste on total biogas yield. Biogas production was improved through co-digestion of cow dung and food waste (FW) containing a small fraction of inoculum under mesophilic temperature (37ºC) over a retention time of 24 days. Co-digestion ratios of 1:1, 2:1 and 3:1 for cowdung/foodwaste were used for the study on anaerobic digestion on the co digested matter. Tests were carried out starting with the preparation of substrates, substrate characterization to determine the moisture content (MC), total solids (TS), volatile solids (VS) and ultimately batch anaerobic digestion experiments under thermophilic conditions (370C). The moisture content, volatile solids and total solids for food waste were 78, 22 and 90.7% respectively while the characteristics for cow dung were 67.2, 32.8 and 96.0 % respectively. From the study, a mixing ratio of cow dung: food waste of 1:2 was found to be the optimum substrate mixture for biogas production at 25595.7 Nml. The accumulated gas volumes of 18756.6, 14042.5, 13940.8 and 13839.1 Nml were recorded for cow dung: food waste ratios of 2:1, 1:1, 1:3 and 3:1 respectively. For a co-digestion containing more of the food waste than cow dung, a higher volume of biogas is produce.

Detailed Presentation

AbstractTo tap the organic waste generated onboard cruise ships is a very promising approach to reduce their adverse impact on the maritime environment. Biogas produced by means of onboard anaerobic digestion offers a complementary energy source for ships’ operation. This report comprises a detailed presentation of the results gained from comprehensive investigations on the gas yield from onboard substrates such as food waste, sewage sludge and screening solids. Each person onboard generates a total average of about 9 kg of organic waste per day. The performed analyses of substrates and anaerobic digestion tests revealed an accumulated methane yield of around 159 L per person per day. The anaerobic co-digestion of sewage sludge and food waste (50:50 VS) emerged as particularly effective and led to an increased biogas yield by 24%, compared to the mono-fermentation. In the best case, onboard biogas production can provide an energetic output of 82 W/P, on average covering 3.3 to 4.1% of the total energy demand of a cruise ship.
