Abstract
To dispose the tremendous amount of garbage produced everyday, Taiwan government has been implementing the policy to build 26 large-scale modern municipal incineration plants for the past two decades. With Nei-Hu Incinerator first being built in 1986, a total of 22 incineration plants has been completed and put into operation. Among them, 15 incinerators are Operation-Transfer (OT) plants. Studies have suggested that compared with Public-Own-Operate (POO) management, OT is more successful and creates more profits. Therefore, it is predicted that OT will still be the main operation mode for incineration plants built in Taiwan. However, due to the successful promotion of resource recycling and waste reduction, and the forthcoming phasing-out of these incineration plants after 2012, it is time for the government to start to reconsider the incinerator policies.hen the Environmental Protection Administration (EPA) evaluates existing incinerator policies or makes resource recycling and waste disposal plans, waste treatment cost is undoubtedly the most important factor to be taken into consideration. Now that Operate-Transfer is the most common and a very effective operation mode for the incineration plants in Taiwan, this study focuses on analyzing the cost factors of EPB of the local governments and the operation & maintainer enterprises under the OT management mode. The cost factor analysis is based on reviewing OT operation and management laws and regulations, authorization contracts, basic design of the incinerators, the waste disposal process, operational organization, and related research and studies. Besides, this study also collect data from the operating incinerators and compares other factors such as their capacity, business waste disposal, and electricity output profit to find out about the efficiency of the incinerators.his study finds that the expenditure of an OT incinerator includes mainly the staff cost, operation service cost, ash treatment cost, feedback fund, and supervision service cost. In addition to the capacity of the incinerator and its basic design, the operation service cost depends on how much profit the operation enterprises can make from electricity output and how much business waste they dispose. It is shown that the bigger the capacity of an incinerator is and the more profit is earned from electricity output and business waste disposal, the higher efficiency the incinerator has. As for the operation enterprises, 90% of the expenditure comes from the staff cost, the operation cost and the maintenance cost, and a high percentage of the operation cost is the cost paid on chemicals. Therefore, it is suggested that the operation enterprises should calculate and find out he proper amount of chemicals they should put in while disposing waste. This can not only avoid wasting chemicals, but also reduce ash production and thus save the following treatment cost.eyword：Operation-Transfer、Municipal incineration plants、Cost factors、peration & maintainer cost、Operation & maintainer contract
