101年事業廢棄物管理-辦理電弧爐煉鋼業及鋁熔煉業之事業廢棄物清理查核專案計畫

中文摘要 我國電弧爐煉鋼業每年產生之有害集塵灰約達18~22萬公噸,97年以前因處理廠容量不足,導致集塵灰貯存量超過50萬噸以上,經環保署及工業局輔導增設處理設施後,國內已有3家共4座煉鋼集塵灰處理設施,總設置處理量達27.4萬公噸,已大於集塵灰產生量,並逐步處理既有貯存之集塵灰,惟仍無法於103年6月底將貯存之集塵灰完全處理,另外煉鋼爐碴再利用亦有安定化時間長及產品滯銷問題待克服。本計畫透過18廠次電弧爐煉鋼廠、2廠次集塵灰中間處理機構、11廠次爐碴再利用機構之現場查核作業及13件次集塵灰貯存延長申請案之審查作業,督促業者確實依廢棄物清理法及相關法令規定妥善處理集塵灰及再利用爐碴,同時透過14樣集塵灰資源化處理後衍生之集塵灰及爐碴,與煉鋼爐碴再利用產品爐碴粒料之採樣分析,掌握其物質特性,經現場查核結果集塵灰及爐碴皆能妥善貯存及清理或再利用,惟部分業者仍有未能達成環保署訂定之集塵灰分年處理目標問題,本計畫已提出解決方案供業者及相關主管機關參考。另外本計畫並完成研析爐碴再利用技術、調查國內再利用設施現況及分析其再利用後產品之經濟效益,提出爐碴加速清理可行措施,供相關主管機關參考解決爐碴再利用問題。此外,本計畫亦透過現場查核8家鋁熔煉業,6家鋁碴中間處理/再利用/最終處置機構及1家鋁碴再利用產品使用業者,督促業者誠實申報鋁碴產出情形及妥清理鋁碴,同時並完成研析鋁碴處理/再利用技術、調查國內處理及再利用設施現況與分析其再利用後產品之經濟效益,提出鋁碴加速清理可行措施,供環保署參考解決鋁碴清理問題。

The Project for the Auditing of Waste Cleanup of Steel-Smelting EAF and Aluminum Smelting Industries

英文摘要 There are about 180 to 220 thousand tones of hazardous electric arc furnace (EAF) dust generated by EAF steel smelting plant every year in Taiwan. The shortage of recycling treatment capacities led to a huge storage quantity of EAF dust of more than 500,000 tons. With the assistance from the Taiwan Environmental Protection Administration (EPA) and the Industrial Development Bureau (IDB), 4 treatment facilities in 3 factories have been established in Taiwan with a total treatment capacity of 274 thousand tons which exceed the annual production amount. The stored dross and dusts were treated gradually but the stored EAF dust quantity still couldn’t be treated completely by June 30 2014. In addition, the problems of product production and selling still need to be reinforced. This project has implemented on-site auditing of 18 steel plants, 2 EAF dust recycling treatment plants, 11 EAF slag recycling treatment plants; examined 13 applications for extending the EAF dust storage period in order to urge the EAF steel-smelting dust and other industrial waste generators to follow the Waste Disposal Act and other relevant laws and regulations. 14 dust and slag samples produced by recycling process and recycled slag pellets were analyzed to clarify the material properties. After on-site investigation, this project has found that the EAF dust and slag were stored, cleaned-up and treated properly, but the stored EAF dust quantity still couldn’t meet the annual treatment goal and complete the whole treatment before June 30 2014. Regarding the problem of couldn’t complete the entire treatment mount of the EAF dust, this project has already proposed measures to accelerate the treatment task and resolve the problems of proper storage of steel-smelting slag. In addition, through investigation of the treatment and recycling techniques and facilities of aluminum dross and dusts, this project has completed economical benefit analysis of recycling products. In addition, the project eight aluminum smelting factories, 6 aluminum dross treatment / recycling / final disposal facilities and one company using aluminum dross recycling products, urging the aluminum smelting industry to report the production of aluminum dross honestly, and to store, treat and recycle aluminum ballast properly. At the same time, the project completed the analysis of aluminum dross treatment/recycling technology, the investigation of domestic processing and recycling facilities and analysis of the economic benefits of recycling products. The project also proposed feasible countermeasures to accelerate the treatment task and resolve the problems of cleanup of steel-smelting slag.
