Abstract EN
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.
