本研究以生命週期評估方法與蒙地卡羅不確定分析方法探討台灣地區廢棄物焚化處理之溫室效應與酸雨效應之衝擊評估，並以1度電與1公噸廢棄物為功能單位，進一步探討紙類與塑膠類對於溫室氣體排放和酸雨潛勢之環境衝擊及不確定分析，以期能作為相關廢棄物管理決策之參考。研究結果包括廢棄物處理生命週期評估結果與闡釋、紙類與塑膠類之生命週期評估與不確定分析及溫室氣體減量之情境模擬。詳細結果如下：
1.焚化廠之生命週期評估經單一得點，以重金屬、溫室效應及致癌性衝擊較高。
2.含生質碳廢棄物之溫室效應，不同功能單位之特徵化約為1.88 kgCO2-eq./KWh及781 kgCO2-eq./ton waste。
3.不含生質碳廢棄物之溫室效應，不同功能單位之特徵化約為1.20 kgCO2-eq./KWh及505 kgCO2-eq./ton waste。
4.紙類廢棄物之溫室效應介於0.68~3.86 kgCO2-eq./KWh及介於 610~865 kgCO2-eq./ton waste。
5.塑膠類廢棄物之溫室效應介於0.68~3.86 kgCO2-eq./KWh kgCO2-eq./KWh及983~1399 kg CO2-eq./ton waste。
6.廢棄物回收率之情境分析，以紙類回收率增加對於溫室氣體減量最具效益。 The aims of this study focused on the environmental impacts analysis for Taiwan's waste incineration by the life cycle assessment (LCA) methods and Monte Carlo uncertainty analysis. Moreover, LCA was performed with functional unit to evaluate the greenhouse effect and acidification etc., for the incineration plants. These results may provide for the policy making for waste management. The results contained the LCA interpretation, uncertainty analysis of the paper and plastic waste, and scenario simulations of green gases mitigation. Detailed results are as follows:
1.The incineration treatment LCA single scores were with the higher value of the environmental impacts like as the heavy metals, greenhouse effect and carcinogenic.
2.For the waste was with the biocarbon content, the greenhouse effect were 1.87 kgCO2-eq./KWh and 781 kgCO2-eq./ton waste.
3.For the waste excepted the biocarbon content, the greenhouse effect were 1.20 kgCO2-eq./KWh and 505 kgCO2-eq./ton waste.
4.The greenhouse effect of paper waste, the values were on the range 0.68~3.86 kgCO2-eq./KWh and 610~865 kgCO2-eq./ton waste by the different functional unit.
5.The greenhouse effect of plastic waste, the values were on the range 0.68~3.86 kgCO2-eq./KWh and 983~1399 kg CO2-eq./ton waste.
6.The scenario analysis results indicated that the greenhouse gas mitigation was more effective by waste recycling.
