摘要：

This research aims to study biogas production in King Mongkut's University of Technology North Bangkok Prachinburi Campus. Information of biogas energy from the food waste fermented in 2,000 liters capacity tank was analyzed to determine the heating value in order to calculate the Net Present Value (NPV), Internal Rate of Return (IR) and Discount Payback Period (DPB). All the measured values from 15 days testing period are the gas quantity of 0.5-0.9 m(3) and the average heat value of 10 MJ/m(3).Ten fertilization chambers that have capacity of 6,000 liters each for biogas production should be replaced the original size of 2,000 liters tank because using the original tank could not reach breakeven point. By using 10 champers of 6,000 liters capacity each, the payback period has yielded within 5 years and 5 months and given the rate of return 22.48 percent per years throughout 20 years of recovery period.
