energy sources are more reliable for energy production and eco-friendly due to its almost zero emission. Biogas as
a sub-product obtained from anaerobic decomposition (without oxygen) from organic residue is one of the most
efficient renewable energy which is currently being developed and commercialized in the world wide. One of the key
interest of biogas plants with energy generation is the disposal of comparatively large amounts of digestible waste
in economically and environmentally sustainable process. This study has investigated food waste produced in
Kangwon National University (KNU) and predicted bioenergy production through anaerobic digestion. The purpose
of this study is to perform economic analysis for predicting bioenergy sales revenue. The economic accomplishment
of the given biogas plant has been analyzed based on net present value (NPV) and payback period (PBP) techniques.
The case study has presented food waste yield of 304.1 tons per year in KNU, electricity yield of 62.41 MWh per
year. The biogas plant is a good economic recommendation according to the economic analysis results by 7.14 years
payback time, earning profits and showing a positive NPV of 12.75 million won.
