To obtain public acceptance for construction of landfill sites, it is important to consider not only the theoretical presentation of non-hazardousness of landfill sites, but also public confidence and public involvement at any planning stages of the landfill site construction. People living around a proposed landfill site tend to demand a non health-hazardous landfill site, which means improvement of the functions of the landfill site, on a negotiation table. On the other hand, an administration finds difficulty in constructing the improved landfill site because of budgetary restriction on public works. Therefore, those contradictory relations cause many difficulties in the negotiation.
The objective of this paper is firstly to examine the above mentioned contradictory relations between improving functions and construction cost of landfill sites, and secondarily to demonstrate the possibility of improved and less expensive landfill sites. Namely, thirty-two typical existing landfill sites were analyzed with regard to construction cost and functions related with improved landfill sites. Based on this case study, three ideally-improved landfill site models were proposed and their costs were estimated. It is concluded that each of the three models is sufficiently equipped with non health-hazardous functions and that the construction cost is reasonable.
