中文摘要	本研究之主要目的為引進最新適當技術評估焚化爐飛灰及底灰中金屬含量及種類是否具有回收之經濟價值和潛力。並依據評估結果提供台灣地區焚化爐所產生飛灰及底灰之最佳管理策略。因此，為引進最新方法進行適當評估焚化爐灰渣中重金屬的回收之經濟價值和潛力，本研究延請國外焚化爐物質流分析專家P. BRUNNER 與S. MOORE擔任顧問，以建構台灣地區大型焚化爐飛灰及底灰中重金屬含量及來源之研析模式。除文獻資料之外，本研究亦針對北中南都會區大型焚化爐進行實地採樣分析，為增加樣品偵測的靈敏度，以感應耦合電漿光譜分析儀分析飛灰及底灰樣品中重金屬組成及各主要金屬之濃度，並同時建立適合國內灰渣樣品分析之技術資料庫。於獲得實地的資訊後，結合文獻資料，以物質流分析方法建構模式，並依所得資訊計算焚化爐有回收潛力之重金屬總含量。根據北中南三廠的濃度來看，重金屬濃度可略分為三群:鐵、鋁為本研究灰渣分析中重金屬含量最高的，銅、鋅、鉛則次之，鎘與鉻則最低。焚化爐重金屬分佈物質流研究結果顯示除重金屬鎘之外，其餘六種金屬皆大部分集中在底渣中。除了目前含量的計算，本研究亦將進行未來含量的預估，試圖提出短、中、長期各地大型焚化爐灰渣中可回收主要金屬總量、各金屬回收率及其潛在價值，以及各種回收技術之成本支出、二次污染防治成本相對比較分析，以供署裡作為施政的參考。

摘要	With very little natural metal resource, Taiwan imports most of the metal minerals for industrial uses and that is obviously unsustainable from a regional perspective. In order to use resource efficiently and reduce the demand of importing metals, recycling or recovering these metals from waste is a necessary and promising practice. Unlike most investigations that focus on toxic effects of heavy metals released from incinerators, this study assesses the recovery potential of metals commonly used and valuable for industries. The partitioning of iron, aluminum, copper, zinc, cadmium, chromium and lead between bottom ash and fly ash was investigated in three large municipal solid waste (MSW) incinerators located in the three largest cities, Taipei, Taichung and Kaohsiung, respectively in Taiwan. The flux of metals that pass through MSW incinerators was then estimated and the potential of metal recovery in MSW incinerators is assessed. The results show that these metals in our investigation can be divided into three groups based on concentration levels: iron and aluminum are the highest in concentration, copper, zinc, and lead are in the middle, and cadmium and chromium are the lowest. There are six metals in our investigation which tend to concentrate in bottom ash except for cadmium. The factors that might affect the distributions, like recycling rate, operation parameters and trash compositions, are discussed as well to explore if there is any regional difference. It is found that there is no obvious regional difference and recycling rates of plastics, rubbers and batteries are highly related to concentration of lead and zinc in fly ash as well as lead and copper in bottom ash. In conclusion, lead and zinc are the potential metals to develop further recovery policy when both concentrations in ash and technological feasibility are considered.

摘要

With very little natural metal resource, Taiwan imports most of the metal minerals for industrial uses and that is obviously unsustainable from a regional perspective. In order to use resource efficiently and reduce the demand of importing metals, recycling or recovering these metals from waste is a necessary and promising practice. Unlike most investigations that focus on toxic effects of heavy metals released from incinerators, this study assesses the recovery potential of metals commonly used and valuable for industries. The partitioning of iron, aluminum, copper, zinc, cadmium, chromium and lead between bottom ash and fly ash was investigated in three large municipal solid waste (MSW) incinerators located in the three largest cities, Taipei, Taichung and Kaohsiung, respectively in Taiwan. The flux of metals that pass through MSW incinerators was then estimated and the potential of metal recovery in MSW incinerators is assessed. The results show that these metals in our investigation can be divided into three groups based on concentration levels: iron and aluminum are the highest in concentration, copper, zinc, and lead are in the middle, and cadmium and chromium are the lowest. There are six metals in our investigation which tend to concentrate in bottom ash except for cadmium. The factors that might affect the distributions, like recycling rate, operation parameters and trash compositions, are discussed as well to explore if there is any regional difference. It is found that there is no obvious regional difference and recycling rates of plastics, rubbers and batteries are highly related to concentration of lead and zinc in fly ash as well as lead and copper in bottom ash. In conclusion, lead and zinc are the potential metals to develop further recovery policy when both concentrations in ash and technological feasibility are considered.
