Feasibility study of producing refuse derived fuel from landfill : case study Phuket sanitary landfill
Abstract:
This study aimed to analyze refuse derived fuel at Phuket Sanitary Landfill and
includes the heat content and economic viability in order to propose an alternative for
solving Phukets solid waste problem. Samples of 200-kg of solid waste at Phuket Sanitary
Landfill were extracted and piled for processing through mechanical biological treatment for
1 and 4 months. Upon completion, the samples were tested with Bomb Calories Meter based
according to ASTM D 5965-07a Standard. Economic feasibility was carried out for each
process to find the net present value, internal rate of return, and benefit-cost ratio.
Findings indicated that the average heating value from the sample processed
through biological mechanical treatment for a month and 4 months were 4,888 and 6,568
kilocalories per kilogram, respectively. The heating values provided were higher than that of
lignite. Regarding economic feasibility, for the 1-month process, the net present value was
844 million baht with an internal rate of return of 936 percent and benefit-cost ratio of 12.84
(10 percent discount rate). For the 4month process, the net present value was 918 million
bath with an internal rate of return of 431percent and benefit-cost ratio of 5.78.
Furthermore, the project sensibility analysis was performed with a higher project cost and
lower benefits. The results were still worthwhile with the exception of the case of a lower
benefit for the 4-month process.
The results revealed that heat generated by processed solid waste from Phuket
Sanitary Landfill were suitable for use as fuel. The product from the 1-month process was,
however, more appropriate for Phukets solid waste problem due to the physical limitations
of Phuket. The findings would be useful as a guideline for solid waste problems in other
areas
