Abstract
The purposes of this research are to analyze cost and engineering economic value of the interlocking block pilot plant using Mae Moh power plant bottom ash. Primary data were collected through the survey of production from interlocking block pilot plant scale 1,000 unit per day. Secondary data were collected from related documents. Net Present Value (NPV), Benefit-Cost Ratio (BCR), Internal Rate of Return (IRR) and to conduct a sensitivity analysis of the project were used to analyze cost and engineering economic value of project. The results showed that the interlocking block pilot plant investment cost is 2,027,000.00 baht, the operation cost per year is 1,707,200.00 baht, and total cost per unit is 6.12 baht. The discount rate at 3 percentages and 7.12 percentages was used to analyze. The engineering economic value analysis showed that the net present value (NPV) was equal to 7,465,205.13, 5,836,766.15 baht, Internal Rate of Return of the project (IRR) was equal to 60.51, 54.34 percentages, The Benefit Cost Ratio (BCR) was equal to 1.45, 1.42 respectively and the payback period was equal to 18.85 months. Therefore, the interlocking block pilot plant using Mae Moh power plant bottom ash project is worth for the investment.
