摘要

本研究採用整體質量平衡法（Overall Mass Balance, OMB）與統計學之迴歸分析（Regression Analysis）方法推求各行業製程之本土化之事業廢棄物產出因子（Discharge Factor, DF），同時針對錄音帶製造程序採用整體質量平衡法與元素質量平衡法（Elemental Mass Balance, EMB）探討物質流分析應用於產出因子之可行性，並分析以EMB推估後的廢棄物產出因子差異，期望能將已建立之DF應用於事業廢棄物之查核管制，以有效達到事業廢棄物管理目標。
本研究的DF驗證結果經過重新修正後，僅4項DF之MAPE值≧30％（預測能力不佳），MAPE值小於30％者則增加為32項DF，由此證明本研究所提出的事業廢棄物DF推估模式所預測之廢棄物產出量具有88.89％的可靠率。
另由元素質量平衡計算結果得知錄音帶製造程序之主要原物料（塑膠製品）中的含氯量百分比平均值（0.177％）與8筆資料之廢塑膠混合物中的含氯量百分比平均值（0.150％）的相對差異百分比為16.51％，結果判定若進料量中的有害成份百分比與出料量中的有害成份相同時，可能可以以一般事業廢棄物之DF推估得有害事業廢棄物中有害成份含量，不需要再分析有害事業廢棄物的成份。再比較分別以EMB、OMB方法求得之DFEMB1與DFOMB1的迴歸分析差異程度，DFEMB1為0.125（噸廢塑膠混合物/噸塑膠製品進料量）；DFOMB1為0.169（噸廢塑膠混合物/噸塑膠製品進料量），兩者之r值皆大於0.9以上且其DF差異程度不大，此顯示以塑膠製品進料量推估廢塑膠混合物產出量具有高度相關。

This paper studies application of material flow Analysis on Discharge Factor（DF）of industrial wastes for surveillance and management utilizing Overall Mass Balance（OMB）with method of regression analysis to estimate the amount of industrial wastes generated. It is mainly aimed at the tape manufacture process and the DF of its is in the work with OMB and Elemental Mass Balance（EMB）to treat practicability of material flow analysis on discharge factor which shows the difference between DF of OMB and EMB. Planning on surveillance and management system was also conducted with the registered data. It will promote the management of industrial wastes fill with ambition more effectively.
It is found that the DF of wastes of each manufacture process by registered data of industrial wastes were to confirm the accuracy of method by MAPE（Mean Absolute Percentage Error）method. The results showed that there were 4 DFs which were MAPE≧30％. After those DF estimate again, there were 32 DFs the MAPE≦30％. In conclusion, the results showed that the reliability of DF predicting production would be 88.89%.
The results of EMB estimation showed that the average percentage of chlorinity（0.177％）on mainly material and average percentage of chlorinity（0.150％）on mainly waste of tape manufacture process were to confirm the difference of method by RPD（Relative Percent Difference）was16.51％. If the hazardous ingredients of input on materials is the same with the its of output on waste, it may would be use DF of general industrial wastes to estimate the amount of hazardous ingredients on hazardous industrial wastes. Comparison between two methods（OMB and EMB）was also made estimate the results on DF of regression analysis of tape manufacture process. It showed that r value on DF of regression analysis of two methods（OMB and EMB）were more than 0.9 which showed that utilizing the amount of input on plastic material to estimate the amount of output on waste had high correlation at the same time.
