摘要

花蓮縣預備設置之垃圾焚化廠，行政院環保署於93年5月25日核定停建；而花蓮縣一般廢棄物仍持續產生，而衍生垃圾無法有效處理等問題。縣內其他鄉鎮現有之垃圾掩埋場也陸續達到飽和及封場狀況下，因應環保署之跨區轉運合作模式，以垃圾轉運站之方式，解決目前焚化廠焚化空間餘裕量，同時也解決垃圾處理問及降低清運成本。
本研究以花蓮縣為個案，分析垃圾轉運站與本縣自建焚化廠何種垃圾處理方式對花蓮縣是可行的。本研究方法採用估算轉運站與擬自建焚化廠之污染物排放量進行比較，及計算轉運站與焚化廠處理垃圾每公噸花費成本，評估轉運或興建焚化廠何種處理方式，對花蓮縣北區五鄉市處理垃圾最適當。本研究空氣污染主要指標進行分析，包含PM、SOX、NOx，結果可知轉運方式之粒狀污染物排放量為0.738公噸/年、氮氧化物排放量為10.86公噸/年與硫氧化物0.015公噸/年，與擬興建焚化產生粒狀污染物1.76公噸/年、氮氧化物排放量為96.69公噸/年和硫氧化物排放量為4.76公噸/年進行比較，焚化排放粒狀污染物、氮氧化物和硫氧化物比轉運處理分別多1.022公噸、85.96公噸與4.75公噸；另依成本分析結果顯示轉運成本處理垃圾成本為2,075元/噸，擬興建焚化廠處理垃圾依據設計量為300公噸/日處理成本為3,118元/公噸， 因鄰近縣市皆有焚化廠處理垃圾，恐將無垃圾進廠焚化情況，每公噸垃圾處理成本為7,961元，本研究結果顯示目前轉運方式適合花蓮縣北區五鄉市處理垃圾問題。

Hualien County is planning to establish an refuse incineration plant but Environmental Protection Department, Executive Yuan decided to stop the construction on May 25th, 2004. However, general waste kept increasing in Hualien County so waste cannot be managed effectively. Other available refusal landfills in the county are gradually full and closed. Environmental Protection Department promotes the cooperative mode of cross-area transfer. Waste transfer stations will avoid the idleness in incineration plants, solve the problem of Waste management, and lower the cost of clearance.
The research takes Hualien County as the object, analyzing whether waste transfer stations or incineration plants established by the county is the more appropriate waste management for Huanlien County. The research compares the evaluation of pollution emission in transfer stations and in incineration plants, calculating the cost of managing a ton of waste in transfer stations and in incineration plants. The evaluation will decide whether transfer or establishment of incineration plants is the best waste management for five cities and townships in Northern Hualien County. The research analyzes main indexes of air pollution, such as PM, SOX, and NOx. The result shows in transfer stations the emission of particulates reaches 0.738 ton/year, the emission of nitrogen oxides reaches 10.86 ton/year, and the emission of sulfur oxides reaches 0.015 ton/year. By comparison, in incineration plants the emission of particulates reaches 1.76 ton/year, the emission of nitrogen oxides reaches 96.69 ton/year, and the emission of sulfur oxides reaches 4.76 ton/year. The emission of particulates, nitrogen oxides, and sulfur oxides in incineration plants is 1.022 ton, 85.96 ton, and 4.75 ton more than those in transfer stations respectively. Besides, the result of cost comparison shows the cost of transfer stations is 2,075 dollar/ton. By comparison, incineration plants are designed to burn 300 ton of waste everyday and the cost is 3,118 dollar/ton. There are incineration plants managing waste in nearby counties and cities so there might be no waste burnt in incineration plants. The cost of managing one tone of waste will be 7,961 dollars. The result of the research shows transfer stations are the more appropriate waste management for five cities and townships in Northern Hualien County.
