中文摘要	國內目的事業主管機關依事業廢棄物再利用管理辦法，公告部分廢棄資源可作為輔助燃料之用途，如廢橡膠、漿紙污泥、紡織污泥、廢木材等，考量國內每年廢塑膠袋膜數量漸增，而此類物質因其回收價值偏低，故目前其去化管道遭遇困難，為提高其再利用價值，並減少其進入焚化爐處理數量，以延長焚化爐使用壽命及避免占用處理量能，亟待規劃相關能源回收試驗計畫，以評估未來作為輔助燃料再利用之可行性。廢塑膠袋材質主要以聚乙烯(PE)及聚丙烯(PP)為主，然部分複合材質或生物可分解材質等亦常混雜於民眾回收之廢塑膠袋中；然因廢塑膠袋之回收價格並不高，且其重量並不重，若以人力或其他篩選或辨識方法執行，恐不符合成本效應；故大多數之回收廠商都不願意進行再次分類。一般而言，熱值在2,000kcal/kg以上時於合適狀態下即可持續燃燒，並認為適合作為燃料或輔助燃料。未經造粒之破碎廢塑膠袋之濕基低位發熱量已達5,290~5,420 kcal/kg，頗為接近燃煤之熱值(約5,000~6,500 kcal/kg)；就熱值之考量觀點，屬適合作為燃料或輔助燃料。本計畫中廢塑膠袋來源為桃園市、苗栗縣、台中市以及新竹縣各地的清潔隊或回收執行單位。本計畫收集處理之廢塑膠袋總量為267公噸，委由長祥環保有限公司進行廢塑膠袋膜破碎及造粒，大量收集之廢塑膠袋將先暫存於受本計畫委託清運廢塑膠袋的鼎壢公司，完成造粒之SRF亦運回暫存於鼎壢公司。試燒場域規劃於永豐餘工業用紙股份有限公司新屋廠2號流體化床鍋爐執行試燒作業，已進行實場試燒約200公噸廢塑膠袋造粒而成之固體回收燃料(SRF)，整體SRF造粒作業期間約為1個半月(9/1~10/15)，本計畫規劃SRF為達RDF-5等級，需壓縮成錠狀/球狀或柱狀，試燒規劃以廢塑膠袋SRF取代煤炭比例最高為10%，試燒試驗期程為10/19-10/23共五天。試燒作業配合執行環境監測作業，包括空氣污染物排放檢測及飛灰及底渣成分檢測作業，以確認試燒污染物排出情形。檢測結果顯示，空污及廢棄物檢測均符合法規規範，也沒有影響原灰渣再利用管道。以上述試驗資料進行評估廢塑膠袋製成之SRF作為取代燃煤之可行性，得到的評估結果為可行，惟因廢塑膠袋的購置價格較低，SRF製造商無獲利之可能，且光以廢塑膠袋製成之SRF的熱值高達9,000 kcal/kg，與燃煤之熱值相差甚巨，難以為中小型規模之鍋爐業者直接採納混燒，故建議SRF製造商可混合回收其他生活或事業廢棄物作為SRF的料源，一可相對獲取較高的利潤，再可降低SRF產品的熱值，有助於後續販賣給鍋爐業者使用。

國內目的事業主管機關依事業廢棄物再利用管理辦法，公告部分廢棄資源可作為輔助燃料之用途，如廢橡膠、漿紙污泥、紡織污泥、廢木材等，考量國內每年廢塑膠袋膜數量漸增，而此類物質因其回收價值偏低，故目前其去化管道遭遇困難，為提高其再利用價值，並減少其進入焚化爐處理數量，以延長焚化爐使用壽命及避免占用處理量能，亟待規劃相關能源回收試驗計畫，以評估未來作為輔助燃料再利用之可行性。廢塑膠袋材質主要以聚乙烯(PE)及聚丙烯(PP)為主，然部分複合材質或生物可分解材質等亦常混雜於民眾回收之廢塑膠袋中；然因廢塑膠袋之回收價格並不高，且其重量並不重，若以人力或其他篩選或辨識方法執行，恐不符合成本效應；故大多數之回收廠商都不願意進行再次分類。一般而言，熱值在2,000kcal/kg以上時於合適狀態下即可持續燃燒，並認為適合作為燃料或輔助燃料。未經造粒之破碎廢塑膠袋之濕基低位發熱量已達5,290~5,420 kcal/kg，頗為接近燃煤之熱值(約5,000~6,500 kcal/kg)；就熱值之考量觀點，屬適合作為燃料或輔助燃料。本計畫中廢塑膠袋來源為桃園市、苗栗縣、台中市以及新竹縣各地的清潔隊或回收執行單位。本計畫收集處理之廢塑膠袋總量為267公噸，委由長祥環保有限公司進行廢塑膠袋膜破碎及造粒，大量收集之廢塑膠袋將先暫存於受本計畫委託清運廢塑膠袋的鼎壢公司，完成造粒之SRF亦運回暫存於鼎壢公司。試燒場域規劃於永豐餘工業用紙股份有限公司新屋廠2號流體化床鍋爐執行試燒作業，已進行實場試燒約200公噸廢塑膠袋造粒而成之固體回收燃料(SRF)，整體SRF造粒作業期間約為1個半月(9/1~10/15)，本計畫規劃SRF為達RDF-5等級，需壓縮成錠狀/球狀或柱狀，試燒規劃以廢塑膠袋SRF取代煤炭比例最高為10%，試燒試驗期程為10/19-10/23共五天。試燒作業配合執行環境監測作業，包括空氣污染物排放檢測及飛灰及底渣成分檢測作業，以確認試燒污染物排出情形。檢測結果顯示，空污及廢棄物檢測均符合法規規範，也沒有影響原灰渣再利用管道。以上述試驗資料進行評估廢塑膠袋製成之SRF作為取代燃煤之可行性，得到的評估結果為可行，惟因廢塑膠袋的購置價格較低，SRF製造商無獲利之可能，且光以廢塑膠袋製成之SRF的熱值高達9,000 kcal/kg，與燃煤之熱值相差甚巨，難以為中小型規模之鍋爐業者直接採納混燒，故建議SRF製造商可混合回收其他生活或事業廢棄物作為SRF的料源，一可相對獲取較高的利潤，再可降低SRF產品的熱值，有助於後續販賣給鍋爐業者使用。

摘要	Pursuant to the management method for the reuse of industrial waste, the government authority in charge of the relevant end-enterprise announced that some waste resources can be used as auxiliary fuels, such as waste rubber, pulp and paper sludge, textile sludge, waste wood, etc., considering the amount of domestic waste plastic bag film each year Increasingly, due to the low recovery value of such substances, the current decontamination pipelines are experiencing difficulties.

Generally speaking, when the calorific value is above 2,000kcal/kg, it can be burned continuously under the right conditions, and it is considered suitable as fuel or auxiliary fuel. The low-level calorific value of the wet base of the crushed waste plastic bags without granulation has reached 5,290~5,420 kcal/kg, which is quite close to the calorific value of coal (about 5,000~6,500 kcal/kg); from the viewpoint of calorific value, it is Suitable as fuel or auxiliary fuel.

Dingli Company of waste plastic bags, and the finished SRF pelletized are also shipped back to Dingli Company for temporary storage. The trial burning site is planned to carry out trial burning operations at the No. 2 fluidized bed boiler of the Xinwu Plant of Yongfeng Yu Industrial Paper Co., Ltd., and the on-site trial firing of about 200 metric tons of solid recycled fuel (SRF) pelletized from waste plastic bags has been carried out. The period of SRF granulation operation is about one and a half months (9/1~10/15). The SRF produced in this project is RDF-5 grade, which needs to be compressed into ingots/spheres or columns. The trial burning plan uses domestic waste plastic bags to make SRF. The maximum ratio of SRF to replace coal is 10%, and the period for trial burning is 10/19-10/23 for a total of five days. The burning trial cooperates with the implementation of environmental monitoring operations, including air pollutant emission testing and fly ash and bottom slag composition testing operations to confirm the emission of trial firing pollutants. The test results show that both tests for the air pollution and waste are in compliance with regulations and specifications, and the original procedures for reuse of both ash and slag are not affected. The above test data is used to evaluate the feasibility of using SRF made of waste plastic bags as a replacement for coal. The evaluation results obtained are feasible. However, due to the low purchase price of waste plastic bags, SRF manufacturers have no profitability. The calorific value of SRF made of waste plastic bags is as high as 9,000 kcal/kg, which is very different from the calorific value of coal. Thus, it is difficult for small and medium-sized boiler plants to directly adopt the SRF (made of waste plastic bags) co-firing. Therefore, it is recommended that SRF manufacturers can mix and recycle other life or industrial waste to be used as the sources of SRF. Which not only can obtain relatively higher profits, and also the calorific value of SRF products is much reduced, which is helpful for subsequent SRF sales to the boiler plants.

摘要

Pursuant to the management method for the reuse of industrial waste, the government authority in charge of the relevant end-enterprise announced that some waste resources can be used as auxiliary fuels, such as waste rubber, pulp and paper sludge, textile sludge, waste wood, etc., considering the amount of domestic waste plastic bag film each year Increasingly, due to the low recovery value of such substances, the current decontamination pipelines are experiencing difficulties. In order to increase their reuse value and reduce the amount of them entering the incinerator for processing, in order to extend the service life of the incinerator and avoid occupying the processing volume Yes, it is urgent to plan related energy recovery test plans to evaluate the feasibility of future reuse as auxiliary fuels. Waste plastic bags are mainly made of polyethylene (PE) and polypropylene (PP).
