| Summary: | 碩士 === 國立臺灣大學 === 農業經濟學研究所 === 102 === The source of energy in Taiwan mostly comes from import. According to the Taiwan Energy Policy Whitepaper (2006), in order to achieve sustainable development targets in the future, the future development strategies of energy in Taiwan include the promotion and utilisation of non-carbon renewable energy. Using chicken manure as the raw material for power plants not only provides an alternative source for energy but also solves the land and water pollution problems from high nitrate concentration of animal wastes.
The main purpose of this research is to evaluate the feasibility of using chicken manure as the feedstock of the electricity power plant in Taiwan. First, we conduct a questionnaire survey to find out how chicken owners deal with chickens'' manure and what factor influences the willingness of manure supply. Then we build a linear programming model to choose the township as the target to set up the power plant in Changhua, and know which townships can become the suppliers of the manure. Finally, we use the cost-benefit analysis to evaluate the feasibility of the power plant investment, and find possible ways for the government to provide the proper incentive mechanism.
According to the questionnaire analysis, the layers'' manure are usually disposed after sun-dried but the broilers'' manure are disposed directly after cleaning in Taiwan. The owners mostly agree to provide chicken manure for burning power but there are significant differences about the willingness to supply manure. Owners who sell manure agree to provide chicken manure for the power plant, but owners who provide manure for free don''t agree to provide manure for the power plant. The linear programming results show that Fangyuan township is the place for setting the power plant due to its low transport costs. The raw material supply come from Fangyuan and Erlin townships.
The power plant using chicken manure does not have the investment feasibility under all three scenarios without any government subsidy. If the government subsidizes the equipments or electric selling prices, then the investment will be feasible under two scenarios. The subsidization based on electricity price is found to be more sensitive than subsidizing the equipment. Thus, with proper policy intervention based on scenarios 2 and 3, there will be opportunity for the power plant to become sustainable.
