Before the end of 2004, Central Taiwan has pushed the policy of trash incinerating. Up to now, there are four large-scale trash incinerators in Taichung city, Taichung County, and Chang Hwa County. Which cause ashes are processed via landfill, however, this way makes our environment unhealthy. In ashes, bottom ashes are in majority but low damage. Now, we are finding the fittest methods to decrease the loading of landfill and drive metal materials in ashes recycling then using residues of silicic acid salt to be substitute.
The research use Analytical Hierarchy Process (AHP) to establish estimation levels to proceed processionals & scholars investigating and matrix mathematical calculations to get the best method of ashes centralizing & recycling plant in Central Taiwan. Of course, financial affairs are also the main point for investors and sponsors when locals participates public development. The research will do feasibility evaluation、setting hypothetical parameters、estimating cost and profit of investment、net present-value(NPV)、internal rate of return(IRR)、discounted payback(DPB)、finance feasible analyzing、and sensitive analyzing for the reference to investors and sponsors.
Total evaluation results display ashes recycling plant building has to pay much attention to the effects of environment. Nan-tung district, Taichung City, predominates the hydrology、geology、ground using、engineering cost、ecology、and present environment over others cities, which is the best one to build ashes recycling plant in Central Taiwan. Regarding to financial evaluation, the business profit will affect planning which if feasible and will of investors. For this reason, we must consider to select area-across cooperation to decrease cost of entrusting operation. In addition, we have to promise years of entrusting operation and the lowest hand over tons to reduce risks of investors but increase locals’ investment pleasure.
