“…Since there is 58% methane in biogas and 21% oxygen in air, 1/0:58 = 1:72 volume of biogas requires 2/0:21 = 9:52 volume of air or one volume of biogas requires 9:52/1:72 = 5:5 volume of air (stoichiometric air requirement). From the complete combustion process, the stoichiometric primary aeration required is 5.5; then, the entrainment ratio r should be r = 5:5/2 = 2:75 [10]. The mixture flow rate at optimum aeration is found from Equation (6) [5].…”

“…The biogas stove does use 65 holes at 5 mm diameters (total burner port area = 12:96 m 2 ) set at 90°to the vertical, and the flames are fairly expanded on the left area. A larger burner port area would allow for greater flame stability [10]. Using 49 holes, with 10 mm gaps between holes, arranged in a circular pattern, gives a total circumference of 65ð10 + 5Þ = 975 mm as shown in Figure 7.…”

Energy shortage is the main problem while preparing food at the university in Ethiopia. Baking of injera consumes a lot of firewood due to the nature of baking mitad and layout of the system. The daily average firewood consumption is 8600 kg which is equivalent to 790.3 m3 of gas. In this study, an investigation of energy yield from food waste is examined by assessing the daily waste generation rate from the university student cafeteria and configuring the baking stove (mitad) that utilizes biogas energy. CFD is used to investigate the performance and heat distribution of baking mitad. In the study, the measured average daily biodegradable food waste and kitchen waste generation rate in the campus is around 863 kg/day. The conversion of this food waste using the anaerobic digestion system yields 43.2 m3 biogas per day. Utilizing the daily biogas generated for baking injera improves the overall food making process and reduces firewood consumption by 5.4%. This biogas energy yield is considered to be utilized for baking injera in the kitchen. The designed biogas mitad (stove) does not generate smoke due to the type of fuel used and configuration of baking mitad. Furthermore, the stove has an insulation mechanism considered to conserve the heat loss to the surrounding. Generally, the utilization of the biogas system and integration of the biogas injera baking stove will improve the overall food processing mechanism in the university.

“…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. They show that a bio filter containing immobilized aerobic sludge was successfully adapted for the removal of H2S and CO2 from the biogas produced using food waste.…”

The major source of odours emission in wastewater treatment plant is biodegradation of sludge, mainly anaerobic degradation. Odours are generated by a number of different wastewater components, first of all the sulphur compounds, hydrogen sulphide (H 2 S) and mercaptans. Domestic sewage contains 3-6 mg/dm 3 organic sulphur, mainly arising from proteinaceous materials and about 4 mg/dm 3 from sulphonates contained in the household detergents and 30-60 mg/dm 3 inorganic sulphur [1]. Anaerobic digestion of organic substances by a consortium of microorganisms through a series of metabolic stages (hydrolysis, acidogenesis, acetogenesis and methanogenesis) leads to biogas formation [2].
